The hydrangea flower fifting ratio is unbalanced
there may be more nitrogen fertage，less phosphop and po钾ferture，causing its vegetative growth to be too strong，which is not advantive to the emergion of flower bads，so that the plants in the second，the first三年内不能正常开花。
maybe because of more watering
when the new shoots of the plant grow to a certain length，they should be given appropriate“water permitter”to inhibit its vegetative growth and promote flower bud differention.
Unappropriate illumination time control
The hydrangea is a short day plant that maintained darkness for more than 10 hours a day for about 6 weeks to form flower bads.促进栽培的植物需要经过6-8周的寒冷期（5-7°C），将植物置于20°C的温度下促进开花。当花序可见时，温度降低到16°C左右，这样它就可以开花2周左右。
