Causes of withered Leaf Tip of domestic Orchid and its solution
Potted orchids often experience leaf tip dryness, or even whole leaf wilt, for the following reasons:
One is caused by orchid anthracnose and round spot. The disease occurs in large numbers during the rainy season or when it is hot and rainy at the turn of summer and autumn. The solution is to spray 1000 times of carbendazim or 50% carbendazim in the disease-prone period, once every 10 days, for 4 times in a row.
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 0 ℃, orchids should be moved to indoor ventilation and sunny places for maintenance before winter. When you move outside in spring, you should pay attention to avoid the harm of late frost. The traditional experience of "no wind in spring, no days in summer, no dryness in autumn, and no dampness in winter" is of great benefit in preventing orchid leaves from drying up.
For the orchid leaves that have been withered at the tip, if the situation is not too serious, the method of manual cutting can be used, using scissors (preferably by alcohol disinfection) by "∧" in the shape of about 10 mm below the dry part, so that it can still be kept full of green, and it is better to spray on the fungicide after pruning.
Note: "not windy in spring, not dry in summer, not dry in autumn, not wet in winter" refers to not moving outdoors too early in spring to avoid strong winds; proper shade in summer to protect against scorching sun exposure; frequent watering in autumn to prevent drought; basin soil should not be too wet in winter to prevent freezing and rotting roots. This statement is in contrast to the natural environment of the south, if it is a heated room in the north, you have to look at it according to your own environment!
