❶ the extreme heat in summer makes many seedlings withered branches, leaves and even dead. For the seedlings that are still in need, the dead branches and leaves shall be cut off in time to help them recover their vigor.
❷ many trees, especially some flowering shrubs, differentiate flower buds in early autumn. If they can be properly pruned at this time, it will not only facilitate the flower bud differentiation of trees, but also improve the lignification of new branches, which will help trees survive the winter safely.
For Prunus pumila, green peach, etc., measures such as twisting the shoot can be taken to control the vegetative growth of its branches and save nutrients for flower bud differentiation. The new branches of other trees can be picked properly. After plucking, the branches are stronger, lignified and have stronger cold resistance. For autumn flowering shrubs such as crape myrtle, rose and hibiscus, the residual flowers should be cut off in time after each flower to prevent their bearing, so as not to consume too much nutrients and affect their growth.
❸ thin cut the over dense branches in the tree crown to prevent them from being ventilated due to over density.
❹ scrape off some sprouts on the trunk with a sickle in time, which can effectively prevent them from growing into large branches.
❺ remove the pest branches, sagging branches, inward branches and branches that affect the tree shape in time.
