How to trim the flowers after the cannon hits four doors

1. Prune the fireworks. The fireworks that have already blossomed will not bloom again, so it is necessary to prune this part of the old branches in time and leave the nutrients to the robust branches to ensure the flowering effect.

2. During the growth of fireworks, don't tear the vines at will, which will cause the fireworks to grow badly and bloom less. When the branches grow to a certain height, topping is needed to promote the germination of new branches, so as to bloom more. Some old branches and weak branches should be cut off in time to avoid consuming nutrients and affecting the flowering in the next spring.
