First, the permeability of the nutritious soil is not good; the soil is overripe or overgrown, and the tussah leaves used before preparing the nutritious soil cannot be overrotted or overgrown. If the nutritious soil is prepared with unmatured tussah leaves, heat will be generated after fermentation in the basin. However, the oak leaves are too rotten and a small amount of river sand is added, which makes the soil quickly become mud in the basin. Under the condition that the soil is sticky, the water content is not easy to evaporate, and the permeability is extremely poor, bacteria often enter from the wound. So when changing the basin, you should be careful not to hurt the leaves and roots. All the above factors will cause local discoloration and decay of the root system, and in serious cases, the whole root system will rot in a very short time.
