Can orchids be topdressed in early winter? & lt phosphorus and potassium fertilizer >

After the solar terms in beginning of winter, no matter what fertilizer is applied, it should be adapted to local conditions:

1. In the southern region, after the beginning of the winter solar term, the daily minimum temperature is still above 15 degrees Celsius, and orchids are still in the growth period, so they can be fertilized completely.

2. However, in the northern region, after the solar term in beginning of winter, the daily minimum temperature has dropped to below 10 degrees Celsius, and orchids are about to enter the dormant period, so it is not suitable to fertilize again.
