Camellia japonica L growth habit

Camellia japonica L is native to China. It likes a warm, humid and semi-shady environment, afraid of high temperatures, and avoids the scorching sun. The suitable temperature for growth of Camellia japonica L is 18-25℃, 13-18℃ from March to September, and 10-13℃ from September to March of the following year. When the temperature is above 12℃, the bud will start to sprout, and the growth will stop when the temperature is above 30℃. The initial flower temperature is 2℃, and the suitable temperature for flowers to bloom is 10-20℃. Camellia japonica L cold-tolerant varieties can tolerate -10℃ for a short time, and the general varieties -3--4℃. In summer, if the temperature exceeds 35°C, leaf burns will occur. Camellia japonica L is suitable for an environment with sufficient moisture and humid air, avoiding dryness. In summer and autumn with high temperature and drought, water or spray water in time, and the relative humidity of the air should be 70%-80%. Pay attention to drainage during the rainy season to avoid waterlogging and rot in the roots.

Camellia japonica L is a semi-negative plant. It is suitable for growing under scattered light. The seedlings need to be shaded for fear of direct sunlight. However, long-term overshadowing is not good for the growth of camellia, with thin leaves and less flowering, which affects its ornamental value. Adult plants need more light to facilitate the formation and flowering of flower buds.

For open field cultivation, choose deep, loose soil and good drainage, the most suitable pH is 5-6. Alkaline soil is not suitable for the growth of camellia. Use fertile loose, slightly acidic loam or leaf-humid soil for potting soil.
