2. Acidity and alkalinity: it's better to use slightly acidic soil with pH value of about 5.5-6.5. Do not use alkaline soil. If you use alkaline soil to breed, the leaves of the plant will be very yellow and wither even if it's serious.
3. Humus: there should be a certain amount of humus in the soil. Only with enough nutrition can the Rhododendron grow better. It can be dug under pine, cypress and so on.
