Simple Guide to Pruning Blueberry Bushes
This pruning guide was written by the growers at DeGrandchamp Farms, a Michigan blueberry farm with over 300 acres of production and decades of experience growing blueberries.
How to Prune Blueberry Bushes (Simple Guide for Healthy Plants)
Simple annual pruning will keep plants healthy and producing higher yields with bigger berries.
This guide explains when to prune blueberries, how to prune young bushes, and how to prune mature plants.
When Should You Prune Blueberry Bushes?
Blueberry bushes are best pruned while the plant is dormant.
The ideal pruning time is:
- Late winter
- Early spring (most preferred)
- Late fall after leaves drop
Spring pruning is usually best because it allows you to identify branches damaged by winter cold and remove them before the plant begins growing again.
Plants pruned in fall may bloom slightly later in spring than bushes pruned during winter or early spring.
Pruning Young Blueberry Plants (First 3 Years)
Young blueberry plants need very little pruning during their first few years. The main goal is to help the plant build a strong structure.
During the first three years:
Remove:
- Broken or winter-damaged branches
- Weak or spindly growth near the base of the plant
This encourages strong upright growth that will support fruit later.
Should You Remove Flowers from Young Blueberry Plants?
This is optional. Once we complete a new planting on our commercial farm, we do not do this as it is too labor intensive for the amount of acres we plant at a time.
However, removing flower buds on young plants allows the plant to put its energy into root and branch growth instead of fruit production. You will not have blueberries the year you do this.
You can remove buds by:
- Pinching them off by hand
- Lightly pruning them off
Stronger plants in the early years lead to much better yields later.

How to Prune Mature Blueberry Bushes
Once plants are established, they should be pruned every year.
Follow these three simple steps:
1. Remove Winter-Damaged Wood
Cut out any branches that were injured during winter.
2. Remove Weak or Low Branches
Remove fruiting branches that are:
- Spindly
- Less than 12 inches from the ground
Low branches produce small fruit and make harvesting difficult.
3. Remove the Oldest Canes
Each year remove 1–2 of the oldest canes and any branches that show weak growth.
This encourages the plant to produce new, vigorous canes, which produce the best blueberries. The best branches for fruit production are 2-4 years old.

The Goal of Blueberry Pruning
Pruning helps manage:
- Plant size
- Plant shape
- Air circulation
- Fruit quality
- Ease of harvesting
Well-pruned blueberry bushes are easier to pick, fertilize, and maintain.
Pro Tip From Our Farm
Blueberry plants naturally want to produce too many small branches. Removing weaker growth each year allows the plant to focus energy on fewer, stronger canes that produce larger berries.
Frequently Asked Questions
Do blueberry bushes need pruning every year?
Yes. Annual pruning keeps plants productive and prevents overcrowding.
What happens if blueberry bushes are not pruned?
Plants become dense and shaded, which leads to smaller fruit and lower yields.
Can blueberry bushes be pruned too much?
Blueberries are very forgiving. Removing older wood and weak growth each year actually improves production.
Need Blueberry Plants?
If you’re planting blueberries at home, choosing the right variety for your climate makes a big difference.
At DeGrandchamp Farms, we grow thousands of blueberry plants each year and supply gardeners with varieties proven to grow well in northern climates.
