Hydrangea doesn't blossom for a long time? Pruning it, the flowers bloom bigger than football.

Hydrangea does not blossom for many reasons, if the light is too weak, it needs to be given more light; if the light time is too long, it needs to be reduced; if it is caused by improper pruning, it needs to be pruned correctly and timely; if the temperature is too high, it is necessary to reduce the temperature; if caused by too much nitrogen fertilizer, it is necessary to reduce the application of nitrogen fertilizer.

First, increase the light.

1. Reason: Hydrangea likes a little shady environment, but it should have enough light. If the light is not enough, it will make it easy to grow, and finally let the leaf grow too big, the growth is affected, the leaf consumes too much nutrients, it will greatly affect the formation of flower buds, resulting in it does not bloom.

2. Solution: move it to a place with plenty of light, especially in winter. In the Spring and Autumn period, you can irradiate it with scattered light.

Second, reduce the lighting time

1, reason: sometimes because it is kept indoors at night by the light, it will let the light time is too long, affecting the differentiation of flower buds, thus affecting flowering.

2, the solution: in the flower bud differentiation, can not give it too long light, less than 10 hours a day, so as to promote its flowering.

Third, correct pruning

1. Reason: hydrangea generally blossoms on the old branch. if the old branch is not pruned, it will affect the flowering next year.

2. Solution: after its flower failed last year, cut off the residual flowers and ensure that there are 3 to 4 buds on each branch, while all other branches can be cut off. The best time is before the end of August.

Fourth, lower the temperature

1, the reason: many hydrangea flowers, they like to stay in a lower temperature environment before flowering, if the temperature is higher than 10 degrees, it will affect flower bud differentiation, resulting in it can not bloom.

2. Solution: when its flower bud begins to differentiate, put it in an environment where the temperature is lower than 10.

Fifth, reduce nitrogen fertilizer

1. Reason: although it likes fertilizer very much, if it is not applied properly, it will affect its flowering, especially if there is too much nitrogen fertilizer, it will have the opposite effect.

2. Solution: after flowering every year, apply less nitrogen fertilizer, and then give priority to phosphorus and potassium fertilizer, so that it can blossom as soon as possible.
