Camellias prefer loose, fertile, acidic soil with a pH between 5.5 and 6.5. Good drainage is very important for the plant, not only to help the roots breathe, but also to avoid water logging and root rot.In addition, it can not be cultivated in sticky or alkaline soil, which is not conducive to plant growth.
1. Coconut bran: Coconut bran is the fiber powder of coconut shell, which is generally the by-product of coconut processing. As a pure natural organic matrix, it can improve the soil structure.Because of its good air permeability and water retention, it is very suitable for camellia, a moisture-loving plant, and its decomposition rate is very difficult, so it can be used for a long time.
2. River sand: For camellia, river sand mainly has the effect of increasing drainage capacity. Usually, the proportion of river sand mixed into the soil should not be too large. Otherwise, if the drainage capacity is too strong, no water can be left, and the plant will grow poorly due to water shortage.In addition, we must use river sand rather than sea sand, which contains salt and is not conducive to plant development.
3. Slag: Slag and river sand have similar effects, and also increase the drainage effect. Because of high temperature burning, sterilization and disinfection are also completed.However, it is usually necessary to immerse in water and filter properly to screen out the powder or large particles and retain the small particles.
4. Garden soil: Garden soil is the soil in the garden. This kind of soil is generally planted with plants, so its composition and structure are all right. It is suitable for planting most plants.But in order to be on the safe side, it is usually disinfected first, exposed to the sun, and then screened and reused.
Cultivating camellias with their own soil can provide a better growing environment.It is usually mixed with garden soil, river sand, slag and coconut bran in the ratio of 3:3:3:1.
