There are many reasons why mint leaves fall off: the temperature of the growing environment is too high and needs to be cooled down; If the air is too dry, it needs to be watered, and then covered with plastic bags to increase the humidity of the air; If it is caused by excessive fertilization, it is necessary to stop fertilization and rinse off the excess fertilizer with water.

First, the temperature is too high.

1. Reason: Mint doesn't like high temperature environment. If the ambient temperature around the plant is too high, the surrounding water will evaporate and the plant will be short of water, which will have a great impact on the plant and the plant will lose its leaves.

2. Solution: Pay attention to helping plants dry. You can move the plants to places where they can't get sunlight when the sun is strong, or you can choose to sprinkle water on the plants to help them cool down.

Second, the air is too dry.

1. Reason: It likes humid environment. If the surrounding environment is too dry, plants will lose their leaves.

2. Solution: In this case, water the plants in time, and then put plastic bags on the plants, which can give the plants a moist growth environment.

Third, excessive fertilization.

1, reason: excessive fertilization will burn its roots, damage the health of plants, and the plants will lose their leaves.

2. Solution: In this case, there are two remedies. First of all, stop fertilizing plants immediately, water plants in large quantities, and let the excess fertilizer flow away from the leak at the bottom of the basin with the water; The second is to directly change the soil for plants to ensure that there is no fertilizer in the soil. After successful soil replacement, normal farming can be carried out.
