1. Cause

When this happens, most of the factors are caused by its soil plate. Because of this phenomenon, the air permeability of the soil is affected, and the water seepage becomes very difficult, so the basin soil will either be in a dry state or in a wet and waterlogged state. If we often do not fertilize it, or the fertilization method is wrong, it is more likely to cause its roots to rot. even if it does not rot, it is easy to cause it not to absorb nutrients, which leads to the stiff seedling of the plant

2. Measures

Once this happens to the plant, we need to solve the problem from the root system

First of all, we should change the pots and root. The specific method is: take it out of the original basin, then cut off some rotten and withered roots, and then put it into the solution of naphthylacetic acid and disinfectant. Soak it for about five hours, and then dry it. Then choose a mud basin that fits the size of the plant and puts a quarter of the coarse slag at the bottom to make it easier to drain. After that, the sterilized river sand is used as the substrate, the seedlings are placed, and then placed in a relatively humid and cool position. A solution containing urea is applied to it once in about ten days, and plant hormones can be added to it

The second is to give it a pot of rejuvenation. The specific steps are: when new leaves begin to grow or new roots grow, you can put a pot on him. At this time, water supply and drainage layers should be added, and the soil needs to be loose and fertile. Give it a few days to slow the seedling after putting it into the pot, and then it can be managed normally

3. Small method

There are some ways to prevent this phenomenon. You can pour some Baijiu before Qingming and autumn, and when you pour Baijiu, you can't splash wine on the plant. It will be effective in a week or two. It's best to use less in the initial stage. When it takes a long time, it will take effect and can't be used after it takes effect
