First, the soil to be applied. Soil is the growth foundation of potted camellia, because the root system of camellia depends on the growth and development of soil, and the water and nutrients needed for camellia life activities are mainly absorbed from the soil. Camellia likes mountain red (yellow) loam with acid, high humus content and loose ventilation, and its pH value is between 5 and 6.5. Alkaline soil or cohesive soil cannot be used as the substrate for potted camellia. Soil preparation: 50% of mountain soil (mature red loam for crops), 40% of sawdust or edible fungus residue, 65,438+00% of cake fertilizer powder or livestock manure and phosphate fertilizer powder, all of which are evenly mixed, properly watered, bagged and aged for more than 20 days in summer and autumn and more than 30 days in spring and winter. This kind of soil is not only loose and breathable, but also can keep fertilizer and water, which is suitable for the growth and development of camellia.
Second, there should be moderate illumination. Camellia needs suitable light, but it is also afraid of high temperature and direct sunlight.
Third, the temperature should be appropriate. Temperature is an important condition for physiological activities of camellia. Camellia likes warmth, and its optimum growth temperature is 18℃ to 25℃, and its relative humidity is 60% to 65%.
