1、 How much soil

For potting maintenance, first select the appropriate flowerpot, and then fill the soil. The soil in the pot should be lower than the edge of the flowerpot, about 2-5cm lower, so as to facilitate watering and fertilization, so as not to overflow the water and wash away the soil. The height of the soil should not be too low. Ensure that the root is wrapped in the soil, so that the root can absorb nutrients. If it is too low, the root exposed outside is also easy to damage the root and affect the absorption. There are no specific requirements for how much soil to put, which can be adjusted according to the size of flower pot, plant growth and soil quality

2、 Other requirements for soil

In addition to the requirements on how much soil to put, it is also necessary to consider the preparation of soil itself. If it is a plant that cannot withstand water and humidity, the soil preparation should focus on air permeability and permeability. River sand, perlite and vermiculite can be added appropriately to increase the effect of air permeability and drainage. If you like nutritious plants, you can use humus soil and garden soil as the main medium, and add rotten organic fertilizer as the base fertilizer at the bottom to ensure good nutrition supply. When potted plants are filled with soil, they can be operated according to specific conditions
