What causes dry, withered tips on orchid leaves? I'm looking for control methods.
Infection with anthracnose and round spot disease can cause the leaf tips to dry up. Orchids are not cold-tolerant, and frost damage can also cause drying. In autumn, the potting soil should be kept moist to prevent the leaf tips from withering due to excessive dryness. In winter, do not water too much, to prevent the plant from freezing injury or root rot.
