Learn how to prune Northern Highbush blueberries to improve fruit size, bush health, and harvest quality. At Chelan Ranch, we prune in early spring every year.
Why Prune Northern Highbush Blueberries?
-
Promotes Vigorous Growth: Pruning helps stimulate new growth in blueberry bushes. Blueberries produce fruit on newer wood, and removing older branches encourages the development of more productive wood.
-
Improves Fruit Quality: Pruning thins out the bush, allowing more sunlight and air to reach the canopy. This improves berry size and sweetness. It also lowers the risk of fungal disease by reducing moisture buildup.
-
Helps in Pest Management: Pruned bushes have fewer dark, dense spaces where pests thrive, making pest management easier using natural methods or fewer chemicals.
-
Increases Yield: Removing dead, damaged, or diseased wood helps the plant redirect energy to healthy branches, increasing total fruit yield.
-
Longevity of the Plant: Pruning keeps blueberry plants productive for many years. Without it, bushes become overgrown and less fruitful, with shorter lifespans.
When to Prune Northern Highbush Blueberries
At Chelan Ranch, our elevation is around 2,000 feet. We prune in March when the buds begin to swell. Early spring helps us tell fruit buds from leaf buds:
-
Fruit Buds: Larger, rounded, and formed at the tips and upper shoots from last year’s growth.
-
Leaf Buds: Smaller, pointed, and found along stems. These produce leaves and shoots essential for photosynthesis.
Understanding this difference is key to effective pruning.
Tools You Need to Prune Blueberries
-
Hand pruners
-
Long-handled loppers for thick canes
-
Gloves (for rubbing off twiggy wood and bloom buds)
Clean all tools before and after pruning to avoid spreading disease.
How to Prune Northern Highbush Blueberries (Step-by-Step)
For Young Bushes (Years 1–3):
-
Remove flower buds in year one.
-
Cut out dead or weak shoots.
-
Keep 3–4 strong new canes each year.
-
Open the center of the plant for light.
For Mature Bushes (Year 4+):
-
Remove old, dead, or broken wood.
-
Cut out canes older than 6 years.
-
Keep only 9–12 of the most vigorous canes from the base.
-
Maintain a balance of old and new canes. Rotate wood by removing the oldest canes and leaving young whips as replacements.
-
Open the interior of the bush to sunlight. This promotes fruiting wood and good hormonal balance.
-
Improve air circulation to reduce disease and stimulate new cane growth.
-
Limit fruiting laterals to 5–6 per upright cane. The best fruit grows on laterals 6 inches or longer.
-
Use gloved hands to rub off twiggy wood. Avoid weak, short laterals.
End Goal: Seek Balance
-
Moderate pruning = Best balance of fruit and growth.
-
Hard pruning = Fewer berries, more new wood.
-
Light pruning = Small berries, weak twiggy growth.
Moderate pruning creates lasting balance and promotes long-term plant health.
