It is common for potted orchids to have dried tips of leaves, and even the entire leaf can wither. The reasons are as follows:
Firstly, it is caused by orchid anthracnose and round spot disease. This disease occurs in large quantities during the plum rain season or when it is hot and rainy in late summer and early autumn. The solution is to spray carbendazim or thiophanate-methyl during the prone period, once every 10 days, for 3-4 consecutive times.
Additionally, when orchids suffer from frost damage or late frost, it is also easy to cause dried or discolored leaf tips. Therefore, in areas where the temperature is below 0℃ in winter, orchids should be moved to indoor ventilated and sunny places before winter. When moving them outdoors in spring, attention should be paid to avoid late frost damage. The traditional experience of "no wind in spring, no sun in summer, no dryness in autumn, and no moisture in winter" is very beneficial for preventing dried orchid leaves.
For orchid leaves with dried tips, if the condition is not too serious, artificial pruning can be used. With a pair of scissors (preferably sterilized with alcohol), cut about 10 millimeters below the dried part in the shape of an "∧". This can still keep the pot full of green, and it is even better if a fungicide is sprayed after pruning.
Note: "No wind in spring, no sun in summer, no dryness in autumn, and no moisture in winter" means not moving outdoors too early in spring to avoid wind damage; shading appropriately in summer to prevent sunburn; watering frequently in autumn to prevent drought; and keeping the potting soil not too wet in winter to prevent freezing and root rot.
