When are apricot trees usually grafted?

Apricot grafting can be divided into three periods, namely, spring, summer and autumn.

The bud shrinks and blackens or the petiole touches but does not fall, indicating that it has not survived and needs to be reconnected in time.

4. Apricot trees should be watered in time before and after grafting to promote sap flow and improve the survival rate of grafting.
