What if the leaf tip of the orchid is dry?

Potted orchids often have leaf tip withering, or even whole leaf wilt, which is mainly caused by orchid anthracnose and round spot. This disease occurs in plum rain season or at the turn of summer and autumn when it is hot and rainy. It can be prevented by spraying 50 grams of carbendazim 1000 times or 50 grams of carbendan once every 10 days for 4 times. Families can buy small packages of sterilized pesticides.

In addition, when orchids suffer from frost injury or late frost, it is also easy to form leaf tip drying or discoloration. Therefore, in areas where the winter temperature is below O ℃, the orchids should be moved to indoor ventilated and sunny places for maintenance before winter. When moving outdoors in spring, you should pay attention to avoid the harm of late frost. Traditional experience: "Spring is not windy (spring should not be moved outside too early to avoid strong winds), summer is not a day (summer should be properly shaded to prevent the scorching sun), autumn is not dry (autumn should be often watered to prevent drought), winter is not wet (winter basin soil can not be too wet, prevent freezing and rotting roots). It is very good to prevent orchid leaves from drying up.

If the orchid leaves that have been withered at the tip of the leaf are not too serious, the method of manual cutting can also be adopted. With scissors (preferably sterilized by alcohol), they can be cut off in the shape of "^" about 10 mm below the dry part, which can still be kept full of green. It would be better to spray the above-mentioned fungicide after pruning.
