How to choose potted soil

Potted plant is a special small environment, because the capacity of potted soil is limited and the buffer capacity of water and fertilizer is poor, so the requirement of potted soil is more strict. Good pot soil should be loose, water permeability and ventilation capacity is better, but also should have a strong water retention, fertilizer holding capacity, but also lighter weight, rich resources. The soil is loose and permeable, which is beneficial to the growth and development of the root system and the activity of rhizosphere fungi; good drainage will not lead to root rot due to stagnant water; good water retention and strong fertilizer holding capacity can maintain sufficient water and fertilizer for the growth and development of flowers.
