How many times a year does hydrangea bloom?

1. How many times does it bloom?

Hydrangea blooms in June every year. It only blooms once, but because of the special nature of its flowering, it always gives people the illusion that it blooms multiple times. It blooms on both old and new branches. The old branches bloom earlier, and sometimes the new branches bloom only after they wither, so there is an illusion that it blooms at least twice.

2. Reasons for not blooming

1. The light is too weak: 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 too long and the flower buds will not bloom due to insufficient nutrients.

2. Improper pruning: Pruning is required after the flowering period every year. If the pruning is improper or not done at all, the plant will grow too vigorously. If it is pruned heavily in early spring, the number of flowers will decrease or even disappear by June.
