1. Prefer warmth and avoid cold. The suitable temperature for camellia growth is 15 ~ 25℃, and when it is higher than 30 ~ 35℃, it grows slowly or is in a semi-dormant state. Camellia will be damaged by freezing at the temperature below 0℃ for a few days, so we should take warm-keeping measures for Camellia. Potted camellia should be placed in a sunny and sheltered warm place to avoid freezing injury. The temperature required for flower bud differentiation of camellia is about 25℃, usually from May to June.
It's better to be half cloudy than hot sun. The sunshine time required for the normal growth of camellia is about 10 hour. When potted in the courtyard or balcony, the sunshine time should not be less than 4 hours to meet the needs of camellia branch growth, leaf bud development and flower bud differentiation. If the light is insufficient for a long time and photosynthesis is reduced, camellia will grow poorly. But camellia is afraid of direct sunlight. Provide sunscreen when the sun is shining in midsummer, and spray water on the leaves or the ground several times to avoid burning the leaves.
3. like humidity and avoid dryness. When flowering in winter, the soil should be kept moist to prevent the flowers from wilting. When new branches and leaves grow in spring, the soil moisture should be higher, so water and spray water in time. At the beginning of flower bud differentiation (May), the soil should be dry to facilitate normal flower bud differentiation. When it is hot in summer and autumn, water it. In particular, potted camellia should be watered 1 time in the morning and evening, and at the same time, the leaves and the ground should be sprayed with water many times to keep the environment moist and spend the summer safely.
I like fertile acid soil. Tea likes loose, fertile, humus-rich and well-drained acidic soil. It is most suitable for planting in a semi-cool and warm place, avoiding the northwest wind. Avoid low-lying water. When potted, the culture soil should be prepared according to the requirements, and the pH value is 5.5 ~ 6.5. And choose purple sand basin, with more padding at the bottom to facilitate drainage and ventilation. Camellia avoid alkaline soil. Camellia is sensitive to alkaline soil. When planted in alkaline soil, the light ones are stunted, the heavy ones stop growing, and the new leaves become smaller and yellow. When the soil is too sticky, the root system of camellia cannot be stretched, and it is not easy to dry and loosen after watering, which is easy to cause root rot. Therefore, whether planted in the ground or potted in camellia, we should choose the culture soil mainly composed of mountain mud or pine needles and rotten leaves, and pay attention to cultivating the soil in Feishan tea garden to create good basic conditions for the growth and development of camellia.
