There is a kind of plant that always blooms quietly in the courtyard when the weather is slightly cooler in late autumn. It is the camellia. When the camellia is cultivated in the garden, it should be accompanied by shade trees or other plants planted on flower stands for shade and warmth. The area generally has better autumn planting. Fertilization must grasp three key periods, namely: apply topdressing fertilizer between February and March to promote the growth of spring shoots and flower buds; apply topdressing fertilizer in June to promote the growth of secondary branches and improve drought resistance; Base fertilizer can improve the cold resistance of plants and lay a good foundation for the growth of new shoots in the next spring.
The size of the pot and the proportion of the seedlings should be appropriate. The soil used for the flower pot is best to add 1/2 to 1/3 cut pine needles that have been decomposed for one year in the garden soil. Avoid potting in high temperature season. Water should be poured enough after potting. In the high temperature season of summer, the leaf surface evaporates a lot, so the leaf surface needs to be sprayed with water.
The water spray should be carried out in the early morning or evening, and avoid spraying water at noon. In winter, the plants gradually enter dormancy, and the frequency of watering should be reduced accordingly. Do not pour cold water under the high temperature and hot sun, so as not to cause the roots to be unsuitable and cause physiological defoliation. In high temperature or windy days, the evaporation of the leaf surface is large, so it should be watered or sprayed more. When the air humidity is high, reduce the amount of watering. Antifreeze measures should be taken in winter. It is advisable to keep potted plants at 3-4°C for overwintering indoors.
If the temperature exceeds 16°C, it will promote early germination. The fertilization, pruning and pest control of potted camellias are basically the same as those of open field cultivation.
