1, slow down. Let 1 year-old branches grow naturally without pruning, which is called slow release, also known as throwing release and long release, and is mostly used in young tree vegetative branches.

2. Shortcuts. The pruning method of cutting off part of 1 annual branches is called short cutting, which is mostly used for branches at all levels to promote crown expansion.

3, thinning branches. The pruning method of cutting or sawing off 1 annual or perennial branches from the base is called thinning.

Step 4 take it back. Cutting off or sawing off a part of perennial branches is called retraction, which is carried out during dormancy.

5. Carve flower buds. Use a hacksaw bar to pull horizontally above the bud and reach the xylem to stimulate the bud to sprout branches.

6. Choose your heart. Before the lignification of new shoots in summer, the tips of new shoots are removed or cut off.

7. Opening Angle: Young sweet cherry trees grow vigorously, with small bottom angle of main branches and upright tree posture. The bottom corner of the main branch must be manually opened in the second year after planting.
