2 Summer pruning Summer pruning includes sprouting, fixing branches, removing cores and removing side branches. (1) Bud wiping: Wipe off buds with bad position and direction, twin buds, medium and weak buds. (2) Fixed branches: according to the planned yield, select and keep branches with good growth and large inflorescences. (3) Picking the core and picking the tip of the attachment: Picking the core is generally carried out before flowering 1 week, and it is best to pick the upper part of the branch above the walnut-sized leaves 2-3 days before flowering. There are 1-2 secondary branches at the top of the new branch, and the rest are all smoothed or 1-2 leaves are left under the inflorescence for repeated coring. For the secondary branch at the top of the new branch, leave 4-5 leaves for repeated coring.
