Management Techniques For Blueberries

1. Key points of pruning management technology after blueberry harvesting 1. The branching point must be selected correctly for pruning blueberries after harvesting. When pruning blueberry trees, look from the bottom up from the base to find the branching point of the main branch. Cut back each main branch 40 cm from the ground. If there are no sturdy spring shoots that can be selected within a close distance above and below the cut of the main branch, simply find an outer bud point on the main branch to shorten the main trunk. If there are relatively sturdy spring shoots within a close distance of 5-8 cm above and below the cut of the main branch, then keep the spring shoots on the main branch at a length of 5-15 cm depending on the situation, and then choose an outer bud point to shorten the spring shoots.
Note: Only the thick spring shoots closest to the bifurcation can be retained on the main branch. Only 2-3 spring shoots can be retained on each main branch. Moreover, when pruning the spring shoots, it is recommended to keep very thick spring shoots long, and pay attention to shortening the relatively weak spring shoots.
2. Pruning after blueberry harvest must leave enough green leaves. When pruning a blueberry tree, 10-15 cut points should be left according to the age of the tree. Generally, dozens of green leaves that can photosynthesize must be left on the tree after pruning. After shortening the main branches and leaving enough branch points, all the thin and weak branches on the blueberry tree that grow too much, too dense, too weak, and too old, as well as those that grow in unreasonable positions and affect the tree's shape, ventilation and lighting, should be directly cut off.
3. When harvesting and pruning blueberries, the auxiliary branches at the bottom must be handled properly. After pruning the main branches of blueberries, all the remaining young and tender upright new shoots should be pinched and topped to remove the growth advantage of the top of the tender shoots and promote the germination of the lower buds. For blueberry trees with weak tree vigor during pruning or with few leaves on the tree after pruning, wait until the main branches are pruned in spring, first keep the thin and weak branches at the bottom, let it use the photosynthesis of green leaves to produce nutrients for the tree body and promote germination. When the new shoots that sprout next grow to 10 to 20 centimeters and have the ability to photosynthesize, then cut off all the thin and broken branches and leaves at the bottom reserved in the early stage.
For blueberry trees that are vigorous during pruning or have plenty of green leaves after pruning, you can either directly cut off all the creeping, thin and broken branches that grow horizontally at the bottom, or you can reserve them for use for 2-3 weeks and then cut them all off
