How to choose potting soil? Good potting soil should have these characteristics

Good potting soil should have the following characteristics: 1. Strong water retention capacity: good potting soil should be able to retain enough moisture to control the humidity inside the pot, providing the bonsai with an environment suitable for its growth. 2. Strong drainage capacity: excess water must be drained out of the pot in time; potting soil with poor drainage tends to become compacted, and at the same time excess water will cause the bonsai roots to rot, directly leading to the death of the bonsai.

3. Good aeration: the soil structure must be good, there must be gaps in the soil, and there must also be a certain amount of space between the soil particles so that the bonsai roots can obtain enough nutrients.

Good inorganic potting soil has very good drainage capacity, and fresh air must be able to continuously enter the soil to ensure the healthy growth of the bonsai,
