1、 Bloom several times

Hydrangea blooms in June every year. It only blooms once, but because of the particularity of flowering, it always gives people the illusion that it blooms many times. It is the old and new branches that bloom. The old branches bloom earlier, and sometimes they fail before the new branches bloom. Therefore, there is an illusion that they bloom at least twice

2、 Reasons for not flowering

1. Too weak light: Hydrangea is a light loving plant. If there is no light for a long time or the light is too weak, the leaves will grow in vain, and the flower buds will not bloom due to insufficient nutrients

2. Improper pruning: pruning should be carried out after the flowering period every year. If the plant grows too vigorously due to improper pruning or non pruning, and it is re pruned in early spring, it will blossom less or not bloom in June
