Ask for advice on Yingshanhong downhill pile. I just bought a Yingshanhong downhill pile. It has many fibrous roots, but it doesn't bring any soil. How to plant it?

Yingshanhong is not afraid of cold, but prefers to bask in the sun. First of all, you should trim and cut the stump according to its future shape, so as to ensure that it can be placed in a very shallow bonsai basin and try not to hurt the fibrous roots. You can find a big, deep basin and plant it with ordinary loose garden soil. Never fertilize it. Choose the front according to the shape, set it in the south sunshine, slowly fill the soil, and move it to the leeward and sunny position, which is better outdoors. Then pour enough water. After the water seeps down, it is best to cultivate wet soil on the pile head, leaving only a few places to germinate. This is called pile cultivation. At least one year or even two years, during which pruning and coring are combined. Then you can go to the bonsai basin to enjoy it.
