1、 What kind of soil

The selection of soil is very important for plant growth. This condition is good and is very favorable for plant growth. It is suitable for growing in sandy soil with soft texture and good drainage performance. It is best to ensure certain nutrition. You can mix vegetable garden soil, humus soil, sand and base fertilizer according to 5:2:2:1 at home, so as to meet its requirements. In particular, it is necessary to avoid the use of sticky and hardened loam, which may be impervious to water and cause waterlogging roots

2、 Precautions

1. It is suitable to grow in slightly acidic or neutral soil, and the pH value should not be too high, otherwise it will affect the plant and hinder the growth in the later stage

2. More soil can be loosened every day, which can keep the loam active and promote water penetration, so as not to produce water accumulation, otherwise the rhizome is easy to rot in the soil with high water content

3. When selecting loam for planting, pay attention to the depth of the buried soil, and bury the soil near the first leaf node of the plant, which can help to grow root tubers in the later stage
