Camellia is one of the top ten famous flowers in China, so how to cultivate camellia? Also known as camellia, it belongs to the camellia genus of the camellia family, and is a type of evergreen shrub and small tree. Camellia flowers are full and graceful, dignified and elegant, and are one of the ten traditional famous flowers in China. It is also one of the world's famous flowers.
I. Propagation methods of camellia: divided into seed propagation, grafting, cutting, and layering.
1. Seed sowing
Suitable for single or semi-double petal varieties. In mid to late October, place the harvested fruit in a well-ventilated indoor area to dry in the shade, and after the fruit cracks open, take out the seeds and sow them immediately. If sowing cannot be done immediately in the fall, store the seeds in sand until February of the following year. Before sowing, seeds can be mixed with a new type of lipid membrane, generally, autumn sowing has a higher germination rate than spring sowing.
2. Grafting
Grafting is an important step in camellia cultivation. Choose healthy semi-lignified branches, cut from bottom to top with one bud and one leaf, one by one. Cut the scion into a楔 shape and place it in a damp towel. Clean the mud and sand from the rootstock seedlings, then cut off 1 to 1.5 cm above the cotyledon, split the stem longitudinally along the cotyledon suture line to the same depth as the cut surface of the scion; insert the cut scion into the split of the rootstock, align one side of the cambium layer, and tie it tightly with a plastic film tape.
3. Cutting
Select the current year's semi-mature branches from the outer part of the tree crown with full tissue, intact leaves, plump leaf buds, and no diseases or pests. The cutting length is generally 4 to 10 cm, with two leaves at the tip and a heel at the bottom. Maintain sufficient humidity during cutting, avoid direct sunlight, and spray water on the leaves to keep a thin film of water on the leaf surface to increase the survival rate.
4. Layering propagation
During the plum rain season, select strong one-year-old branches, perform a ring-shaped stripping 20 cm from the top, 1 cm wide, wrap it with decomposed leaf soil and cover it with plastic film. After about 60 days, roots will form, and it can be directly potted, with a high survival rate.
II. Growing environment
To know how to cultivate camellia, you need to understand its growing environment. Camellia prefers fertile, loose slightly acidic soil, warm, humid, and semi-shaded conditions. It dislikes high temperatures, avoids direct sunlight, and dries out. Temperature is one of the important conditions for camellia growth, with a suitable growth temperature of 18 to 25°C. It is slightly cold-resistant, with most varieties able to withstand -10°C low temperatures, heat-resistant, but growth is inhibited above 36°C. High or low temperatures are not conducive to camellia growth.

III. Cultivation management
Camellia cultivation does not require high demands, but some things should be noted. Soil is the fundamental condition for camellia growth and should be chosen with high humus content, slightly acidic soil, and kept from being too dry or too wet.
IV. Watering
Water more in spring and summer, and water every two to three days in winter; water moderately during normal times. Avoid waterlogging, which can cause root rot. The amount of watering should change with the seasons, with fewer waterings in winter. Never water with cold water under high temperatures and strong sunlight. If the humidity is high, reduce the amount of watering.
V. Fertilization
Do not over-fertilize or apply heavy fertilizers, as this can damage the roots and reduce the number of flowers. It is best to use organic fertilizer as the base fertilizer for camellias, which are plants that like fertilizer. Generally, during the growing period, adding phosphorus and potassium fertilizers is beneficial for camellia growth, making the flowers more lush, but also be careful not to over-fertilize.
VI. Disease prevention and control
Camellia is prone to red spider and scale insect infestations, which can be controlled by spraying 40% omethoate emulsion 1000 times dilution or cleaning thoroughly. During the plum rain season, high humidity often causes anthracnose, which can be controlled by spraying equal parts Bordeaux mixture or 25% carbendazim wettable powder 1000 times dilution.
The above is the experience of how to cultivate camellia trees to make them grow well, as well as the cultivation and maintenance of camellia flowers, hoping to be helpful to you in your life!
