Step 2: Solution
Move the flowerpot to the shade, spray more water on the branches and leaves to increase the humidity, and the evaporation of water will take away some heat, thus cooling the asparagus.
Improper temperature
1. Reason
Asparagus has a temperature suitable for its own growth. Generally speaking, the optimum temperature of asparagus is between 65438 02℃ and 65438 08℃. Staying in a low environment for a long time will cause frostbite, which will lead to slow metabolism and yellow leaves.
