It will clump when you hold it tightly in your hands, but will fall apart when you release your hands. Using soil prepared in this way to grow plants can promote rooting.

2. Soil preparation mainly based on hard planting materials: the materials used are weathered rock particles, small stones, pine bark, and humus. After mixing the above materials, use a sieve to sift out three sizes of soil. Use the large planting material at the bottom of the pot to facilitate drainage, the medium planting material in the middle, and the small planting material on the top. Using this kind of soil to grow it will make it grow stronger and stronger.
