1. Soil requirements1. Air permeability: The soil for planting azaleas should have good air permeability. If it is too sticky, it will be detrimental to the growth and breathing of the plant roots. 2. Acidity and alkalinity: It is best to use slightly acidic soil with a pH value of around 5.5-6.5. Do not use alkaline soil. If you use alkaline soil to grow the plant, the leaves of the plant will be very withered and yellow, and in severe cases, it will die. 3. Humus: There must be a certain amount of humus in the soil. Only with sufficient nutrients can it be more conducive to the growth of azalea. It can be dug from under trees such as pine and cypress. 2. Soil preparation methodMost home-based farming uses prepared soil for cultivation, and you can use leaf mold, sandy soil, and a small amount of base fertilizer. If the soil is a little heavy, add some broken tiles to the bottom of the pot. The soil must be disinfected before mixing and can be exposed to the sun. You can also add some coal slag to the soil to improve drainage. It is not recommended to use red soil as this type of soil is relatively sticky. |
