(1) Whether overwatering: Although orchids like a humid environment, never overwater, which causes root rot and withered leaves.
(2) Whether too little fertilizer or overfertilization: Too little fertilizer makes orchids malnourished and causes withered leaves; overfertilization causes fertilizer burn and withered leaves.
(3) Whether too much light: Orchids are flowers that love shade and fear sun.
(4) Whether humidity is too low: Orchids require humidity kept between 60-80%; too dry conditions cause withered leaves.
(5) Whether the temperature is low: Orchids are suited to surviving in a warm environment; low temperatures or freezing both cause orchid leaves to wither.
(6) Whether they have contracted diseases or encountered pests: These both cause orchid leaves to wither.
(7) Whether to repot and change the soil in time: Generally, orchids should be repotted and have their soil changed once every 2-3 years or so.
(8) Whether air pollution is present in the environment where the orchids are cultivated: Orchids are one of the indicator flowers for air pollution and are very sensitive to it. For example, they are very sensitive to cooking fumes, coal smoke, smoke and dust, paint, air fresheners, chemical synthetic agents, insecticides, and so on. The slightest carelessness causes orchid leaves to wither or even die.
