The ideal soil for these types of plants is one that has a sandy texture and a somewhat more acidic pH. However, it can grow in other types of soils without any problem. What it is more demanding is in terms of drainage. We remember that drainage is the capacity of the soil to be able to filter rain or irrigation water.
