Late winter to early spring, before bud break, is a good time to prune blueberries. You want to be certain the plants are dormant when you prune.
Suggestions made during this tutorial include:
- prune out old canes or weak shoots
- when pruning out older branches, remove old canes as close to ground level as possible
- blueberries fruit on one-year old shoots
- swollen buds are fruit buds
- smaller, pointed buds result in vegetative growth, which will be the fruit wood in the following year
- best fruiting canes are three to six years old
- removing at least 50% of the fruiting potential each year results in higher quality fruit and a longer, healthier life for the blueberry bush
