Do blueberries fruit on old or new wood?
Understanding Blueberry Fruit Production The fruit is produced on the tips of side-shoots which were new the previous year. (In essence, fruit is produced on year-old wood.) The most productive canes are around three years old. Wood that is over four years old begins to lose vigour and eventually becomes unproductive.
Can you prune blueberry bushes in the summer?
Our growing season is long enough that we can prune blueberries soon after harvest (by the end of July, as a rule of thumb), and the plants will have time to set flower buds (from which fruit develop) for the next year on shoots that grow after pruning. Jul 3, 2019.
