What to do if the leaves of Michelia turn black

1. Humid environment

(1) Specific reasons: There are two possible situations. One is determined by the weather, the humidity of the environment is relatively high and the surroundings are relatively humid. The second is caused by artificial watering. Watering too much at one time will cause water to accumulate in the container.

(2) Solution: If it is caused by climate, then we have no way to adjust it and can only move it to a relatively drier place. If it is the second case, then it is within our adjustable range. Although it has a high demand for water, excessive water can cause harm. In general, we should follow the principle of seeing dry and seeing wet. The most important thing is not to have too much water.

2. Fertilizer problem

(1) Specific reasons: We all know that the concentration of fertilizer applied to most plants cannot be too high. Otherwise, it will cause damage to the roots. Among them, one very important external manifestation is the blackening of leaves. Then there is the question of quantity. Even if the concentration is appropriate, applying too much is not good.

(2) Solution: If this is the reason, the concentration and amount of fertilizer must be adjusted and adjusted in time. Try to use a lower concentration and more often. Also, don’t take too much each time.

3. Bacteria Problem

(1) Specific reasons: There are some harmful bacteria that may cause plants to become sick and then the leaves turn black. This is also a very likely reason.

(2) Solution: Cut off the infected and blackened leaves. Then, spray the appropriate medicine. Then you need to adjust the surrounding environment. It cannot be too humid.
