< Back The Food Explorer (The True Adventures of the Globe-Trotting Botanist Who Transformed What America Eats By Daniel Stone Do you ever wonder where the tasty vegetables, fruits and spices we consume come from? No, I am not talking about the grocery store, or your backyard garden. I am talking about where in the world they originated and how they got to North America. Enjoy this review of “The Food Explorer” by Daniel Stone. And I am certain that you will be tempted to click on your Amazon app and purchase the book! Review by Linda Holt, Master Gardener Did you ever wonder where your banana came from? Or how about that juicy navel orange you crave every morning not only for its sweetness but also for the healthy dose of Vitamin C it provides? Avocados, surely, they are a California staple, along with the almonds we enjoy in everything from the true nut to the almond milk used as a substitute for dairy milk (originally brought to California from Spain by the Franciscan Padres). I must admit that I have always been under the false assumption that America just had these treasures in abundance when this country was founded. I, like many Americans, assumed that the variety of food grown in my garden or purchased from farmers markets and grocery stores, has always been a part of our heritage. However, “The Food Explorer,” corrects the false idea that the incredible wealth of fruit, vegetables, nuts, and even cotton, that we enjoy originated in the United States. This fascinating book explains the origin of these plants from many varied countries and jungles around the world. Author Daniel Stone, armed with a multitude of seemingly endless journals, letters and records, shares the delightful and fascinating story of David Fairchild, a late-nineteenth century food explorer and his benefactor Barbour Lathrop, a wealthy, private citizen whom he met aboard a ship bound for Italy. As a 20-year-old botanist, David left his Kansas home to work for the Department of Agriculture. There he studied ways to combat plant fungus. Along with a colleague named Wallace Swingle, he created a new government agency that they called the “Office of Seed and Plant Introduction”. Between the years of 1894 and 1904, David (consumed by his wanderlust for travel) searched the far reaches of the world for the unusual and delectable. Over that time he transported an inventory of over 4,000 plants; including avocados and watermelons from Chili, Soy Beans from Indonesia, Meyer Lemons from China, nectarines from Pakistan, kale from Croatia, hops from Bavaria and pomegranates from Malta to name a few. It wasn’t always easy, as some of the plants would not survive the journey or due to the abundance of plants and the lack of qualified people to handle them at home, some would eventually die before they could be moved and reproduced. Additionally, he suffered diseases, bargained with island tribes and was once arrested. One of the most fascinating things that Daniel Stone contributed to our nation is the introduction of the cherry blossom tree from Japan. After David fell in love with and married Marian Hubbard Bell (daughter of Alexander Graham Bell), he decided to relinquish his extensive travels and purchase a 10 acre parcel located near Chevy Chase Maryland. There he began to fill the space with his favorite trees and shrubs that he found during his travels. Marian had only one plant request: the Japanese flowering Cherry tree that she referred to as “Cherry Blossom.” The consequential history of this famous tree that outlines the DC Capitol streets is quite extensive and is best read rather than condensed herein. David Fairchild did lead an enviable life that was made possible by happenstance and living during a time period known as “the Gilded Age,” a time of rapid economic growth and industrialization. His story, as told by Daniel Stone, is a fascinating read. I hope you enjoy it as much as I did! Photo credits: book jacket

< Back Put these insects under gardening law until you annihilate THEM! Marjorie Blare, Dakota County Master Gardener This is the time of year when bugs, not eliminated earlier in the year, try to take over your plants. Don’t get those creepy-crawly pests ruin your houseplants. Read this article to learn how to prevent getting those bugs and how to eliminate them if they manage to creep in. THEM : A HORROR HORDE OF CREEPY-CRAWLY PESTS CLAWING OUT OF THE SOIL AND FROM UNDERNEATH LEAVES! Kill one and two take its place! Steps you can take to reduce the chances of an infestation: Chose the right plant for the place it will live; take into consider light, temperature, soil/air humidity and air circulation. Before bringing them inside, inspect stems, tops and undersides of leaves (also the pots), for insects, webbing, holes and eggs. Things you can do to treat infestations: Use a forceful stream of water to dislodge insects. Physically remove pests with fingers or tweezers. Use yellow sticky traps to trap flying insects like whiteflies, fungus gnats or thrips. Small numbers of scale insects can be scraped off with a fingernail file or the like. Re-pot using new soil and sterilized pots, making sure to thoroughly wash off old soil. Prune if a pest issue is limited to a few leaves, stems or branches. Dispose of the entire plant if it’s heavily infested.

Apply chemicals outdoors whenever possible. Use a well-ventilated area to spray plants indoors. Enclose your plant in a plastic bag and seal shut. Cut a small hole and insert your spray nozzle. Spray your plant, especially under the leaves. Remove the nozzle and quickly cover the hole with duct tape. Keep it out of direct sun until dry. CAUTION: Mention of a pesticide or use of a pesticide label is for educational purposes only. Always follow the pesticide label directions attached to the pesticide container you are using. Be sure that the area you wish to treat is listed on the label of the pesticide you intend to use . Remember, the label is the law. Never use any pesticide on a plant that is moisture-stressed. Water the soil a day or two before applying pesticides. extension.umn.edu Managing insects on indoor plants With no natural enemies indoors, inspect your houseplants weekly for insect pests like mealybugs and scale.

< Back Chow Mein – A Vegetable “Left-Overs” Recipe Joy Johnson, Master Gardener Joy Johnson is a prolific vegetable grower. She has found this recipe for Chow Mein not only delicious but helpful in making use of the abundant vegetables in her cupboards. Whether using your own vegetable stash or those purchased at the grocery store, you will enjoy this recipe! Are you buried in vegetables from your garden? Like me, can you not bear to weed out plants or seedlings? I am always sure that everything will fit in the garden and that not everything will grow and produce. I am usually wrong on both counts! I have a very full garden with the raspberries hanging over the broccoli and the beets, the cucumbers growing on the fence because there is no room for them on the ground and the tomatoes growing up and over the fence, with no room to walk in between the plants. And then I’m always sure I’m never going to get very many vegetables as they start out few and far between, suddenly I’m buried in bowls full of veggies on my kitchen table! Here is a recipe that I’ve been making for years to use some of my mountain of vegetables. Since the words “Chow Mein” actually mean “left-overs”, I have proven over the years that it turns out no matter what vegetables I put in it (don’t put in tomatoes though) and no matter what quantity of vegetables are used. You don’t have to put in the chicken, and if you want it spicier, you can add Italian sausage. If you need to add more sauce because of the quantity of vegetables, you can easily double that part of the recipe. I often serve it topped with the crunchy Chinese noodles and/or cashews. Chow Mein Prepare and have ready: 1 lb pork, beef, chicken or shrimp. (I usually use chicken) cut in thin slices. 3 c. celery, sliced diagonally 2 c. onions, sliced lengthwise ¾ c. mushrooms, fresh or canned (drain) 3 c. fresh bean sprouts Combine in a small bowl and set aside: 1 T. fresh ginger, chopped OR ¼ tsp powdered ginger 1 tsp sugar 3 T. cornstarch 5 T. soy sauce ¾ c. soup stock or reconstituted bouillon Heat in a large skillet: 1 T. oil. Add meat and stir-fry just until done. Remove from heat. In another skillet, stir-fry in 1 T. oil each vegetable just until slightly cooked. Add each vegetable to meat skillet after stir-frying. Just before serving, reheat meat mixture and add sauce. Cook just until sauce thickens and clears. Serve hot with rice and enjoy!

< Back Making Delicious Meals with Hardy Vegetables Joy Johnson, Master Gardener Master Gardener Joy Johnson is an accomplished vegetable grower but even she struggled this year with the effects of the hot weather and drought on her crops. Still, she offers 4 tried, true and delicious recipes for using the vegetables that were garden champions this year. You will want to read this article for inspiration in the kitchen! It’s the first of August and I’m hoping your garden is flourishing this month. I must tell you, with the drought and the rain and the storms, some of my veggies are doing great and some are struggling along. Gardening is always a gamble, we do our part to plant, weed, fertilize, mulch and water, but sometimes even with all that TLC our veggies might not produce like the seed catalogs promised they would. I consider it a challenge. My garden has thrown down the gauntlet, asking me if I can make something nutritious and delicious with its sometimes-meager offerings. I accept that challenge! Since I like to eat lighter in the summer, I have been focusing on soups and salads. Here are a couple of soup recipes and a colorful salad. The Italian Garden Vegetable Soup is vegetarian and is quick and easy to make. The Zuppa Toscana is my hack of Olive Garden’s soup of the same name. This is a heavier cream-based soup, and makes great use of tons of kale, which you may have in abundance right now! And the Broccoli Slaw is a triumph over critters and heat. This month I also included a Martini drink recipe. My brother and I grow lots of basil and this cocktail that he came up with is a cool, refreshing use of basil. Grapefruit is one my favorite fruits. You can use canned grapefruit juice, but fresh squeezed elevates this cocktail to a gourmet level. Italian Garden Vegetable Soup (makes 6-8 servings) 2 medium zucchinis, sliced 2 medium yellow summer squash, sliced 1 small or medium eggplant, peeled and diced 6 medium tomatoes, diced (whatever variety you grew are fine) 2-4 ears of corn, kernels cut off the cob (steam first, then it’s easier to cut them off) 2 parsnips, peeled and thinly sliced 1 clove garlic, minced 2 cups veggie broth (store bought or homemade) 1/2 cup chopped fresh basil 1/4 cup chopped fresh parsley (dried is fine too. You’ll see I used dried in the photo. My parsley didn’t do well this year, but I have plenty of dried from last year) 1/4-1/2 tsp onion salt Salt and pepper Place all ingredients in a large pot. Bring to a boil and then reduce heat to steam vegetable in broth for 10 minutes. Add more salt and pepper if you’d like. Zuppa Toscana (make 8-10 servings) 1 large white onion diced 1 ½ pounds ground Italian sausage. I have a home blend of venison and spicey Italian port sausage that is quite spicey. You can use a mild Italian sausage or a spicier variety depending on how much heat you want. 7 small red potatoes, peeled, quartered, and thinly sliced 2 cups chicken broth 4 cups water 1-2 tsp red chili flakes (don’t use this if you use a spicier sausage) 1 pint whipping cream 1 large bunch of kale, tough stems removed, and leaves chopped Chicken bouillon powder. In a large pot, brown the onion and sausage; drain fat. Add potatoes, broth, water, and chili flakes. Cover pot and bring to a boil for about 20 minutes, until potatoes are tender. Stir in the cream. Soup will thicken the longer you keep it warm and stirred. Mix kale into hot soup for about the last 5 minutes of cooking. Taste and adjust seasoning with small addition of bouillon, if desired. Cashew Broccoli Slaw (makes 6 servings) I grew tiny cabbages, a couple of red ones and a couple of green ones (lots of insect damage). But you don’t need a lot to make this tasty salad. My broccoli also didn’t produce much. I consider it a triumph that I can use what I grow to make something good regardless of its quantity or quality. Dressing: 1 cup plain yogurt 1/3 cup sugar 1 T apple cider vinegar In a medium bowl, whisk together yogurt, sugar, and vinegar until smooth. Salad: 1 medium sized head of broccoli, washed, peel the stems and chop 1 small head of red cabbage, washed and thinly sliced and chopped 1 small head of green cabbage, washed and thinly sliced and chopped 1 carrot, grated or julienned ¼ cup garbanzo beans, drained and rinsed ¼ cup chopped green onions 1 cup raisins or craisins 1 cup cashew pieces, salted Add broccoli, cabbage, green onions and raisins/craisins to the bowl. Fold slaw mixture into dressing until evenly coated. Chill until ready to serve. Toss cashews into the salad right before serving. Dale’s Grapefruit-Basil Martini 3 parts fresh-squeezed grapefruit juice 1 part grapefruit vodka (Dale uses Citron – the one with no added sugar) ½ part Elderflower liqueur (Dale uses St. Germain) ½ part fresh lime juice ½ part simple syrup to taste (1 part sugar, 2 parts water) 1-2 springs fresh basil 2-3 drops grapefruit bitters Muddle basil in the grapefruit juice and refrigerate for 24 hours in a Mason jar. Stir or shake periodically. After 24 hours, strain out the basil (a few remaining green flecks are okay). Mix all ingredients in a shaker with ice, shake and strain into a martini glass. Garnish with basil (which really provides more of a basil punch!) Photo credits: Joy Johnson (1, 2, 3, 4, 5)

< Back Rain Gardens Whether you live in a city or along a lake or river, managing storm water run-off is something to consider in your landscape. Read this article to finds ways to do it. Whether you live in a city or along a lake or river, managing storm water run-off is something to consider in your landscape. Roof tops, roads, driveways and sidewalks create impervious surfaces. These surfaces cannot absorb water. If rainwater and snow melt is not able to be absorbed into the soil, run-off occurs. Run-off can carry sediments and pollutants such as oil, pet waste, debris and nutrients from lawn clippings and fertilizers. These pollutants can then end up in our rivers and lakes. Even municipal storm sewers may lead directly to rivers and lakes. Simply put, a rain garden is a shallow depression filled with selected trees, shrubs, flowering plants and grasses designed to allow rainwater run-off to absorb into the soil. Rain gardens help to filter pollutants, absorb nutrients and allow sediments to settle before entering the ground water. Rain gardens are also useful in controlling erosion by trapping and allowing the water to infiltrate rather than run down a slope. Also, rain gardens may add interest and beauty to a landscape, or add elements to attract butterflies and birds. While rain gardens are a popular trend right now, not all landscapes offer suitable sites. There needs to be enough room to allow water to be absorbed into the soil and not seep into a nearby building or basement. Also, if the soil is heavy clay or already saturated ponding may occur; and ponds have a different purpose in the landscape. Some situations can be amended to allow for proper infiltration. In these cases it is best to consult a specifically trained professional. Dakota Soil Water & Conservation District offers Landscaping for Clean Water workshops in rain garden design and implementation. Site selection, size, shape, choosing proper plants and other materials, and maintenance are all topics covered in the workshops. Demonstration sites have been planted as part of previous workshops to show how attractive and beneficial rain gardens may be.

< Back Fall Scavenger Hunt by Mary Gadek, Dakota County Master Gardener Come join the adventure of a fall scavenger hunt as a Junior Fall Garden Detective! Teach the child in your life how to detect the arrival of autumn in Minnesota. Read along here for a guide to gathering clues and using some scientific observations in an outdoor search to confirm fall’s arrival. It is time for all Junior Fall Garden Detectives to investigate how we know that fall has returned to our yards and gardens. Let’s find the clues, scientific observations, and evidence your child can collect about fall. Then, participate in a scavenger hunt revealing autumn’s cool air, shorter daylight, and changes in gardens, creatures, and our lives. CLUES As the seasons change from summer to fall, the air temperatures drop and the days get shorter. Look for these clues to determine when the seasons change: ● Air temperatures . The Minnesota average temperatures on September 1 are 77 degrees daytime, 59 degrees nighttime. By November 1, the temperatures have decreased to an average of 50 degrees daytime, 35 degrees nighttime. ● Daylight . From the start of school in early September through the end of September, you may have noticed less daylight each day as you hop on your school bus in the morning until you are playing at the park at the end of the day. Daylight on average decreases by one hour and 15 minutes from August 1 through October 15. The equinox is when the days and nights are said to be equal in length for the entire globe. For the Northern Hemisphere, (the northern half of the world), where Minnesota is located, the fall equinox will be on September 22, 2024, at approximately 7:43 am, kicking off the start of the season. EVIDENCE Some scientific observations, or evidence, of the seasonal changes may include: ● Trees . Trees and bushes are dropping an array of leaves with bright reds, yellows, oranges, and browns. Burning bush (or Euonymus alatus), along with oaks and maple trees create intense red leaves. River birch and yellow poplar trees have showy yellow displays in the fall. ● Plants. Flowers and plants around the yard have lost their blooms and dropped their leaves as their energy returns to their roots below the ground. The final fruits of many plants are ready for harvest, like apples and pumpkins. ● Creatures. The arrival of fall invites the creatures in your yard, or local park, to either migrate to the warmer south or prepare to hunker down for the Minnesota winters by making nests or dens. Birds, like Canadian geese, wood ducks, and the loon, form flocks and fly south. Look up to the autumn sky as the migrating birds fly in a triangular formation to head to warmer locations. Butterflies, like the monarch, partake in a long journey to winter in warm Mexico. You may notice that the butterflies are no longer to be found in the garden. Other animals, insects, and birds remain in Minnesota during the winter by hibernating, or sleeping, in covered areas or under the brush of the colorful fallen leaves and nearby evergreens. Look closely, squirrels are collecting seeds and acorns to save up for their winter meals. SOLVE Now, it’s time for a fun expedition outside in your yard, neighborhood, or local park to search for these clues and evidence of fall and its impact on our daily lives.

< Back Snow Mold! It’s Not About Putting Snow in a Mold As the snow begins to melt, you may start to see a grayish, and sometimes pinkish, circular straw-like, matted patch in your yard, especially near the street where snow was piled up for what may have seemed like decades to some but was only a few months. The spot can also have a “webby” fungus appearance. If you have this phenomenon in your yard, then click on this link to learn about snow mold and what you can do to prevent it from happening again next Spring. Janelle Rietz-Kamenar, Master Gardener Snow Mold is a fungus that develops and thrives when early, deep snow covers the ground prior to the ground being frozen. Snow mold can continue to grow once the snow has melted in the Spring as long as the conditions remain wet and cold. There are 2 types of snow mold found in Minnesota: Gray snow mold produces sclerotia which look like dark, hard round bodies on the grass blade. Pink snow mold produces pink-colored spores and fuzzy mycelium. Areas of your lawn that are affected with snow mold will generally take longer to green up in the Spring but usually come back to normal and therefore, is not usually too serious. In a bad weather year, it can, however, kill the grass. If you want to “spring” into Action this Spring: You can choose to break up and spread the larger snow piles around in the affected areas. This will help the snow melt faster and dry out quicker. You can gently rake the area to create a faster drying process and prevent further mold growth. Preparation to avoid snow mold altogether must be done in the Fall with these easy steps: If your yard is prone to snow mold, skip a Fall nitrogen fertilizer which the fungus thrives on. Continue to mow your lawn until the grass stops growing. Cut grass to 2 inches (but not shorter) to prevent the grass from matting and allowing mold to grow. Rake up leaves If you have certain areas in your yard where snow mold is a problem, consider a snow fence to reduce large piles of snow. While snow mold can be a little unsightly in the Spring, a few actions can help alleviate the problem quickly!

< Back Extend the Growing Season with Greenhouses Mickey Scullard, Dakota County Master Gardener The doldrums of winter are upon us and gardeners are drooling over seed catalogs and dreaming of fresh vegetables and riots of flower colors. But spring planting is still several months away. This is an excellent time to research gardening season extenders such as greenhouses, cold frames, and low tunnels. They could help you start your growing season sooner in the spring and last longer in the fall. To determine which one(s) will best meet your growing needs, there are some key questions you will want to ask yourself and information you’ll want to consider. This article explains the basics and provides helpful resources to move your from – that’s interesting to – I’d like to try that in my yard. The doldrums of winter are upon us and gardeners are drooling over seed catalogs and dreaming of fresh vegetables and riots of flower colors. But spring planting is still several months away. This is an excellent time to research gardening season extenders such as greenhouses, cold frames, and low tunnels. They could help you start your growing season sooner in the spring and last longer in the fall. To determine which one(s) will best meet your growing needs, there are some key questions you will want to ask yourself and information you’ll want to consider. A greenhouse can be described as a place to grow plants inside. Greenhouses can be heated or unheated. They are usually made of glass or plastic to enable light to shine through and they have a roof. Using the sun, the greenhouse captures heat and light. This then generates warmth for plants to grow. Greenhouses also allow gardeners to control the environment because plants grown inside the greenhouse are not subject to the wind, variable rain amounts, and temperature extremes. You may be able to manage pests like insects more easily, and that means you can use fewer pesticides. And if you, like many of us, are plagued by rabbits or deer, you may be able to keep them away from your plants, too! Unheated Greenhouses An unheated greenhouse allows a gardener to start plants earlier in the spring and extend the harvest season longer into the fall months, but it will not be usable during the winter. To use a greenhouse all year in Minnesota, it needs to be heated. Heated greenhouses increase the costs not only of construction but also for operation. (More on heated greenhouses, known as “Deep Winter Greenhouses” below.) Determining the purpose of the greenhouse will help you decide which option is best in terms of function and costs. Greenhouses may be standalone or may be an added structure to your house, garage, or sheds such as a lean to. They need to be placed in a location that receives full sun. Next, you need to determine the building materials, which will be based on whether you want a heated or unheated greenhouse. Size may be dictated by your available space, availability to sunlight, and how you hope to use your greenhouse. Sizes can range from tabletop greenhouses to a tent-like shelf structure to large buildings with room for several people to work simultaneously. Greenhouses need to be anchored so they don’t fly away or tip over. They need ventilation to provide air flow but also to vent excessive heat so plants don’t burn or keep warmth in on colder days. Flooring needs to allow for drainage and prevent weeds from growing. And once the structural items are addressed, shelving and benches to hold the plants and other supplies will need to be selected. If a greenhouse doesn’t fit in your budget, you may consider these options, which may be less expensive, to extend your growing season. For individual plants, you could use a cloche, which is sometimes called a bell jar. It protects individual plants from cold temperatures and other weather extremes. Cold frames, which are essentially mini-greenhouses, can be created using old windows, doors, or other building materials, with glass or plastics. They are an excellent method for starting some seeds, especially the cool weather loving plants like lettuce, broccoli, spinach, cauliflower. They can also be used to get seeds started indoors used to being outside without full exposure to the cold, wind, or rain. Another option you may be less familiar with is low tunnels, which are usually temporary structures that basically create a barrier to the elements like wind, cold, excessive rain, and pests. They can be built with PVC pipe, electrical conduit, or rebar that are used to create hoops that are covered by plastic. The plastic can be purchased at home improvement stores or local hardware store and is recommended to be between 0.8-2 mil. Deep Winter Greenhouses Greenhouses in Minnesota must be heated to be usable year-round, unless they are constructed using Deep Winter Greenhouse (DWG) methods. This is a new approach to creating a year-round growing environment in the cold North, enabling gardeners and producers to grow vegetables in a non-heated structure. Building a greenhouse with heat and operating the heating source, as well as the maintenance costs, can become costly and often make them unobtainable for the majority of home gardeners. The University of Minnesota Extension calls DWGs passive-solar greenhouses that use energy from the sun to generate heat. This lessens the need to use traditional heating methods. This is accomplished by careful alignment of the building structure in an east-west position. The south facing direction is built out of a glazing wall, which can be angled based on the latitude of the site to maximize solar energy. This is advantageous for northern climates especially on very cold days. Inside the DWG, the air heats up, is blown underground, and stored in a thermal mass made of soil or rocks, essentially acting like a battery. While this does create a great growing environment, DWGs are not suitable for all plants. Plants that do best grow in minimal light and include lettuces, herbs, Asian greens, sprouts, and brassicas e.g., bok choy, broccoli, cauliflower, cabbage, choy sum, kohlrabi, napa cabbage, rutabaga, turnip. The initial set-up costs for DWGs, with an estimate of $18,583 to build ($33 per sq ft) with annual costs ranging from $35 to $2,148 depending on what fuel sources are used, how many seeds are purchased and quantity and type of soil and amendments are used. There Regional Sustainable Development Partnerships (RSDP) and Center for Sustainable Building Research have created a DIY version of the DWG Starting a DIY Deep Winter Greenhouse Operation on a Budget . Aimed more toward farmers than backyard gardeners, it may still provide some information that may be useful on a smaller scale. The RSDP also provides blueprints, construction manuals, resources, and information on other types of solar greenhouses. This has been a very brief overview of greenhouses and other growing season extenders.

< Back A Plain Vanilla Murder and Hemlock Now that your outside garden has been put to bed for the winter, take some time to relax and read some entertaining plant fiction. As reviewer Gail Maifeld explains, reading the mysteries - “A Plain Vanilla Murder” and “Hemlock” by Susan Wittig Albert, is not only fun, it’s educational. Written by Susan Wittig Albert Reviewed by Gail Maifeld The garden is put to bed so put your feet up with two delicious mysteries by Susan Wittig Albert: A Plain Vanilla Murder and Hemlock. Both mysteries incorporate the titled herbs as the premise for the mystery plot and are the two latest books in The China Bayles mystery series. A Plain Vanilla Murder takes place in and around the fictious town of Pecan Springs, Texas. China and Ruby Cox are presenting a workshop entitled Plain Vanilla. China’s workshops are popular but someone at this workshop has a deadly motive. China is puzzled when a dear friend’s daughter disappears, a university professor is found murdered, and a fragile, rare orchid is stolen from the professor’s lab. Much is at stake: plant patent, an orchid that is extinct in the wild, & the life of an innocent girl. Learn about the most taken for granted herb vanilla. Did you know it only grows wild in Chili because that is where the unique insect lives that has the physiology to pollinate vanilla? Hemlock takes China Bayles to the mountains of North Carolina where an old & rare book is missing from the gardening book collection of the Hemlock House Library. This rare book, A Curious Herbal, was written and illustrated in the 1730’s. Hemlock is a compelling mix of mystery and herb lore. A member of the carrot family, hemlock looks like Queen Anne’s Lace and is lethal to humans and animals. The addition of a haunted house, a ghost, the local Hemlock Society, and a shooting, all create an absorbing novel. Learn about Vanilla and Hemlock while enjoying a mysterious romp that includes red herrings and suspicious characters. Photo Credit: Gail Mailfeld (1,2)

< Back Vegetables Indigenous to North America Interest in native or indigenous plants, including fruits and vegetables, is on the rise as people begin to understand how these plants promote both a healthy environment and a healthy diet. This article will explore some of the vegetables that are indigenous to North America, including Minnesota and provide some useful references for those interested in exploring this topic more thoroughly. Larry Caola, Dakota County Master Gardener Intern and Julie Harris, Dakota County Master Gardener Interest in native or indigenous plants, including fruits and vegetables, is on the rise as people begin to understand how these plants promote both a healthy environment and a healthy diet. This article will explore some of the vegetables that are indigenous to North America, including Minnesota. But first, let’s define some terms. Indigenous vegetables are defined as “locally-produced (usually within traditional systems), socially and culturally accepted as local foods, and eaten by previous generations or introduced for a very long time.” https://www.ishs.org/ishs-article/1102_27 . “A plant is “native” if it has occurred naturally for thousands of years in a region, ecosystem, or habitat without human introduction. https://www.nwf.org/Native-Plant-Habitats/Plant-Native/Why-Native . Minnesota is home to a wide range of native and indigenous plants and vegetables each with many different cultivars. An important source for indigenous plants in Minnesota is a work by Frances Densmore - Plants Used by the Chippewa Indians , originally published in 1927 and later retitled How the Indians Use Wild Plants for Food, Medicine & Crafts . Densmore documented nearly 200 plants and their uses for food, medicine, dyes, charms, and crafts. Her work offered a firsthand look at the plants used by Indigenous communities across Minnesota. For example, she recorded the use of Spreading Dogbane for heart issues and Chokecherry bark for stomach ailments—remedies later validated by U.S. pharmacological references. Her contributions remain deeply influential today. (See references below.) While it’s easy to find general references to staple crops like beans, squash, and corn, it is more difficult to uncover exact cultivars. Densmore’ book is an excellent source for this research. Frances Densmore More recently, many organizations are attempting to identify and save seeds that are indigenous to North America. In Minnesota, environmentalist and Native American activist Winona LaDuke initiated the White Earth Land Recovery Project to protect indigenous seeds, help the community to overcome type-2 diabetes and also strengthen the community’s spiritual and cultural heritage. Other organizations that are working to catalog and conserve indigenous seeds are Seed Savers Exchange and Slow Food International’s Ark of Taste . One organization, Food Tank, has compiled a list 20 foods that are indigenous to the people in North America. Some foods on this list are familiar and some or not: but all are interesting. Acorns (California native oak trees) American Persimmon Wild Rice (Anishinaabe Manoomin) Bay of Fundy Dulse (a red seaweed from Canada) Blue Camas (Pacific Northwest, root vegetable) Candy Roaster Squash (Appalachian Mountain native) Chaya (native to Yucatan Peninsula, evergreen plant) Chiltepin Pepper (southern U.S., very spicy) Cholla Cactus Flower Buds (southwestern U.S.) Garambullo (central Mexico, sweet red or purple fruit) Highbush Cranberry (native to Alberta, Canada) Mesquite Beans (southwestern U.S.) Ostrich Fern Fiddleheads (northeastern North America) Pawpaws (largest edible fruit in North America) Ramon seed (superfood used by Mayans) Roy’s Calais Flint Corn (northern U.S. and Canada) Seminole Pumpkin (native to the Everglades) Tehucan Amaranth (indigenous to the Tehuacan Valley of Mexico) Tepary Beans (southwestern U.S.) Wild Ramps (wild onions native to eastern North America) Indigenous vegetables that are more familiar locally include beans, corn and squash. One traditional method of growing these crops is known as the “Three Sisters.” The term “Three Sisters” refers to corn, squash, and beans traditionally grown together using intercropping techniques. These plants support one another: corn offers structure, beans enrich the soil with nitrogen, and squash shades the ground to retain moisture and suppress weeds. This method has been used for generations, and studies have confirmed its effectiveness. Three Sisters plots have shown significantly better soil health—including higher CO₂ respiration and nitrate levels—compared to monoculture plantings. Corn – Red Lake Corn One variety native to Minnesota is Red Lake Corn, cultivated by the Red Lake Ojibwe along Red Lake’s southern shores. This eight-rowed corn features mixed white and blue kernels, occasionally with red. It’s a distinct and culturally significant variety grown by skilled Indigenous farmers. Beans – Pole beans Cherokee Trail of Tears pole bean . The Cherokee people carried these beans with them during their forced removal from their ancestral lands, highlighting their importance as a source of sustenance and cultural identity. For purposes of the Three Sisters, look for varieties that will grow up and wrap around corn stalks. Many varieties with roots in North America are available. Squash – Cucurbita maxima Cucurbita maxima , one of the five cultivated squash species, originated over 4,000 years ago in South America. Though it favors warmer climates, some varieties have historically been grown in cooler regions like Minnesota. Frances Densmore referenced it as a basic but important food source. This long-vining plant needs full sun, fertile soil, and space to spread. Its seeds also have medicinal uses, and the fruit is versatile—great for soups, roasting, or baking. Some varieties are even grown for ornament or livestock feed. Squash, Cucurbita maxima If you are interested in growing heirloom vegetables indigenous to North America, look for Native seed companies like Seedsavers Exchange.

< Back Seed Bombs - An Explosion of Color Julie Henrichs, Dakota County Master Gardener The calendar has turned to March and the excitement builds in anticipation for Spring, but wait, I can’t plant seeds outside yet. Don’t worry, DIY seed bombs are a great way to get your hands dirty and also introduce your children and grandchildren to a way of transforming a barren or hard to grow area of your yard into a beautiful flower spot. Seed bombs date back to the 1930’s when Masanobu Fukuoka, a Japanese microbiologist had many areas of his farm that were overgrown with weeds. He created seeds bombs and spread them throughout his farming land and found this to be an effective way of farming and eco-friendly as well. Urban settings also utilized seed bombs in the 1960’s and 1970’s when they were used to clean up urban neighborhoods and create “green spaces”. Seed bombs are great gift for family and friends as well. What is a Seed Bomb and How Do We Make Our Own? Seed bombs are a combination of seeds, clay and compost placed together to be placed or thrown in areas that need beautifying. The clay mixture protects the seeds from creatures that would eat it (ex. insects and birds) and the compost provides the nutrients for the seeds to germinate and grow. What You Need : Powdered Clay (can be found at craft stores or on-line or air-dry clay) Potting Soil or Compost Native/Local Wildflower Seeds (not all seeds will germinate so use a variety of native, non-invasive wildflower seeds) Water Container for Mixing Let’s Make Seed Bombs : Mix All Ingredients – 1 Cup Seeds 5 Cups of Soil or Compost 2-3 Cups of Clay Powder (Air Clay can also be used, but adjustments as to the amount of clay may be needed. Slowly mix in water with your hands until everything sticks together, then roll mixture into firm balls. Balls can also be formed into fun shapes like hearts or stars too. Place seed bombs in an area to dry. Once seed balls are dry and the weather is warm enough then it is time to plant the seed bombs. Plant your seed bombs by throwing them at bare spots of your garden and wait to see what pops up!

< Back Why are Those Bugs Swarming Around My Front Door? Julie Harris, Master Gardener As the weather is growing cooler, you may be experiencing a mass of bugs swarming your outside walls and doors. As we get prepared for winter, the bugs that don’t die off, survive by burying themselves in the soil, or leaves. But there are a few who want very much to spend the winter inside your home. The “big three” offenders are boxelder bugs, Asian lady beetles, and brown marmorated stinkbugs. These bugs may not be noticeable in the summer when they live and feed on sources in your yard. As the weather grows cold, however, they look for ways to get into your warm house. They are especially drawn to the part of your house that gets afternoon sun. Brown Marmorated Stink Bug These bugs are most prolific during hot, dry summers following warm springs. This year may have produced the right conditions for them to be quite plentiful. In the fall, the bugs look for cracks and spaces around doors and windows to sneak into your house. While they are not generally harmful, they can be an annoyance. They don’t feed on wood or other building materials and they don’t spread disease to people or pets. However, Asian lady beetles sometimes bite when handled and they, along with the stinkbugs create a bad smell when stressed or crushed. Asian Lady Beetles The best way to manage these bugs is to seal cracks and holes around windows, doors and foundations. Check window screens, broken seals around doors and windows. Don’t forget to look at the seals around wires, pipes, vents, soffits and fascias. If you have large invasions, you can treat the outside of your home with an insecticide treatment although targeting these bugs is difficult. As they are not feeding while they are trying to invade your home, pesticides may not work. (Note that any use of pesticides must be done with utmost care as they carry some risk.) Once inside, your best option is to remove them with a vacuum or broom or just crushing them. Note that vacuuming won’t kill the bugs, so they should be disposed of outside. These bugs generally do not live for more than a few days inside your home when they are active but they can be a nuisance, staining surfaces with their excrement. Some bugs remain inactive in your home over the winter. If you see them inside in the spring, they are waking up and trying to go outside. They are generally slow moving and can be eliminated fairly easily. In short, these bug invaders are big on the ICK scale but generally can be controlled without causing harm.
