Why does the orchid bud wither?

1. Caused by high temperature

1. Reason: the bud of an orchid usually begins to breed from April to May. And it takes a summer for them to bloom. If the temperature is too high in summer, its bud may be spoiled by the heat and wither.

2. Treatment: when it is hot in summer, move it to a cooler position in the house, or a better ventilated position, to cool it down.

Second, the air is too dry

1. Reason: if the environment for the conservation of orchids is particularly dry, the humidity is 20% or even lower. The water in its bud will volatilize in large quantities and become dry.

2. How to deal with it: move it to a position with relatively high humidity, or put a basin of water on the ground near it. To increase the humidity around it.

III. Excessive fertilization

1. Reason: if too much flower fertilizer, especially nitrogen fertilizer, is applied when it is pregnant with buds, it will cause it to be in a state of overnutrition and keep growing branches and leaves, but the bud will become dry.

2. Treatment methods: proper control of fertilizer, especially flower fertilizer with more nitrogen, can be suspended temporarily. Wait for its bud to grow smoothly, then resume the application.
