What if the orchid doesn't blossom for many years?

The internal cause of orchid not blooming for many years: the root system of ① is underdeveloped and the plant is not sturdy. In order to absorb more nutrients and lay a good foundation for flowering, it is necessary to strengthen fertilizer and water management in order to make the roots of orchids more and longer, strong and disease-free.

② is planted on a single plant, and orchids "like to gather together but afraid of leaving their mother", so try not to plant a single plant.

The external reason why orchids do not blossom for many years: lack of ① light: full light in winter and spring and semi-shade in summer and autumn.

The fertilizer amount of ② before flowering is insufficient: in order to apply enough phosphate fertilizer 5 months before flowering, it is appropriate to use Shihuabao 3, borax, potassium dihydrogen phosphate and other fertilizers.

Insufficient watering of ③: the pot soil was too dry in autumn, which hindered the accumulation of nutrients in orchids and seriously affected the germination and flowering of orchids in the second year. Therefore, we should pay attention to watering in autumn, do not let the basin soil too dry.

④ diseases and insect pests: timely prevention and elimination of diseases and insect pests.
