1、 Causes of new buds and black leaves

1. The loam is too wet: the newly emerged buds have black leaves, which may be due to the failure to take care of their own hands when watering, and the application of too much water, which makes the moisture of the loam inside become very large, so it accumulates in the root, which is a precursor of root rot, and the root can not absorb water well, so black leaves will naturally appear in some of the new buds

2. Fertilizer burn: Generally speaking, the root system is relatively delicate. If nutrients are not applied according to its natural growth, but high concentration chemical fertilizer or fermented raw fertilizer are used, the root system will be burned and the effect will not appear

2、 Corresponding solutions

1. When too much water is found, it needs to be stopped immediately and placed in a well ventilated place, but there can be no direct sunlight and some astigmatism to speed up the evaporation of water inside. If it is confirmed that it has rotten roots, take out the plant, cut off the rotten part and replace it with new pot soil

2. If there is too much nourishment, you can irrigate the water and dilute the fertilizer. It can be carried out continuously for many times and can be saved
