What causes orchid buds to wither

1. High temperatures
1. Cause: Orchid buds generally begin to form from April to May. They then go through a summer before they bloom. If the temperature is too high in summer, the buds may be damaged by the heat and wither.
2. Solution: During periods of high summer heat, move it to a cooler spot indoors, or to a well-ventilated spot, to cool it down.
2. Air that is too dry
1. Cause: If the environment where the orchid is grown is very dry, with humidity at 20% or even lower, the moisture in its buds will evaporate in large amounts and they will dry out.
2. Solution: Move it to a spot with relatively higher humidity, or place a basin of water on the ground near it, to increase the humidity around it.
3. Too much fertilizer
1. Cause: If too much flower fertilizer is applied while it is forming buds, especially nitrogen fertilizer, it will end up in a state of excess nutrients, constantly growing branches and leaves, while the buds dry out and wither.
2. Solution: Control fertilizer appropriately; in particular, fertilizer with a high nitrogen content can be temporarily stopped. Once its buds have grown successfully, resume applying it.
