I love to eat blueberries and also wanted to add some bushes to my yard for pollinators and privacy and beauty. So, adding a few blueberry bushes seemed to be a good option. We planted 5 blueberry bushes a couple of years ago and have moved them around the yard a couple of times, trying to find a location where they would thrive. In the process, I’ve learned several things that you can do for your blueberries in early spring before they’ve even budded that will help them thrive.

Blueberries have very shallow roots, so remove all weeds and grasses that may have grown up around the bushes, then add a layer of mulch 3-4 inches thick. After that, look carefully at your bushes and prune out any dead or dying branches. Also prune out any conflicting growth; branches that are growing into the center or crossing over or rubbing against other branches. 

Another thing to do is to step back and look at the overall shape of your bush and prune so it has a balanced look on all sides. For smaller branches, use a bypass pruning shears or snips. For larger more mature bushes and branches, use a pruning saw. You should do this pruning while the bush is fully dormant, and no buds have formed.

Blueberries need an acidic soil with a pH between 4.5 -5.5. There are a couple of ways to amend the soil around your blueberry bushes. You can use elemental sulfur pellets available at Walmart, Fleet Farm, Ace Hardware and on Amazon. Wear gloves when you apply. Wait to apply until the soil temperature is at least 55 degrees. Sprinkle 2 handfuls in a ring around the plant, on top of the mulch and then lightly rub it into the mulch.

You can also use a fertilizer that has a 5-3-3 balance or get a fertilizer like Plant Tone or Holly Tone. These are usually promoted as evergreen and azalea food (those plants also like a more acidic soil). Only fertilize once this year.

Then you should add a layer of compost 2-3 inches thick in a 2-foot diameter ring around your bushes. Make sure your compost smells like grass, not garbage, to ensure that it is fully composted.

Next add 3 inches of a natural mulch, not dyed. For example, bark mulch, woodchips, cedar or hay, or pine straw. Mini pine bark nuggets are mildly acidic and can help acidify your soil. Make an 18–24-inch ring around your bushes, 2-3inches deep.

The last step is to wet down the entire area. Keep in mind that doing all these things, like adding compost and mulch, won’t last all year. Check your bushes throughout the growing season watching for decomposition, bare soil, and/or weeds starting to creep in. Pull the weeds, reapply a 2–3-inch layer of mulch as needed.

Then look forward to a delicious blueberry harvest.
