1、 What kind of soil

1. Nutrition: the soil used for the cultivation of house roll silk must be nutritious, which can provide the demand for growth, give sufficient nutrients to the plant, and promote the healthy growth of house roll silk. If the soil is very poor, it is difficult to absorb nutrients normally, and the growth will be relatively slow

2. Air permeability: it is also important to ensure air permeability. It cannot withstand water and humidity. If it grows in an environment with too much ponding for a long time, it is prone to problems and the root will rot. therefore, air permeability is also very important. Sufficient air permeability is needed to make the root breathe and breathe normally

3. Drainage: it is also necessary to ensure the performance of drainage, so that if you accidentally apply too much water, you can also ensure the normal discharge of water, so as not to accumulate in the flower pot, which can help the root

2、 Preparation method

First, lay a layer of ceramsite on the bottom part, which can play the role of drainage. The soil inside can be prepared according to the proportion of rotten leaf soil, coarse sand and vermiculite, and a little bone powder should be added inside, so that it can have both air permeability and nutrition at the same time. Pay attention to changing the new basin soil every two years to ensure that it can grow healthily and normally
