1. Temperature.

If you want camellias to grow better, the growth temperature must be controlled at 18-25℃. Too high or too low temperature will affect its growth. When the temperature is high in summer, you should pay attention to sun protection to avoid excessive temperature. If it is too high, it will burn the branches and leaves; when the temperature is low in winter, it can be moved indoors and allowed to receive appropriate light when there is sunlight during the day.

2. Water.

A humid environment can make camellias grow better. You can water them more appropriately in spring and summer, and water them less in winter. Generally, watering once every 2-3 days is enough. Always ensure that the soil is not too dry or too wet.

3. Fertilize.

Don’t forget to fertilize it when breeding. Appropriate application of phosphorus and potassium fertilizers during the growth period can make it grow better and bloom more lushly, but be careful not to fertilize too much.

4. Pruning.

Pruning can help camellias grow better. It is best to prune when the flower buds are too dense. Generally, weak and diseased branches should be cut off, which can help it absorb nutrients better and prevent the flowers from withering. It should be cleaned up in time to reduce nutrient consumption.

5. Change pots.

Generally, you need to change the pot once after one year of breeding. When changing the pot, it is best to change to a larger pot, which will be more conducive to the growth of the roots. The best time to turn over is April, and you can adjust it appropriately during the process. Remove some old roots, add some base fertilizer and water appropriately.

Extended information:

1. Breeding environment.

1. Soil: Camellia is suitable for loose, acidic soil with good drainage. Calcareous soil must not be used.

2. Watering: When new pots are placed, the watering should be sufficient and thorough. The amount of watering can be determined according to the weather, as long as the soil remains moist; in summer, you can water more appropriately. Meet its germination needs; it is best to water in the morning or evening in summer; pay attention to drainage during the rainy season to avoid water accumulation.

3. Fertilization: Camellia does not like fertilizer, so there is no need to fertilize too much. Generally, mixed fertilizer is used, mainly phosphate fertilizer, but nitrogen fertilizer is also acceptable. The fertilizer must be fully decomposed before it can be used. Apply more fertilizer when it is strong and weak. Fertilize less or not at all when seedlings are growing.

4. It likes a warm and humid environment. It should be given sufficient light in spring and rainy seasons to prevent the branches from becoming thin.

2. Reproduction methods.

1. Propagation by cuttings: Cut relatively strong branches to a length of about 10 cm, remove all the leaves in the lower part, and leave 2-3 leaves in the upper part. After cutting, water some water to ensure the soil. Keep it moist and it will take about two months for roots to take root.

2. Layering propagation: Select the last year's branches, peel the bark at the high-pressure part, and cover it with a film, then tie the lower opening tightly, fill it with culture soil, and tie the upper opening tightly. Once the roots have taken root, cut them off before planting.

3. Common pests and diseases.

Common pests are generally stem borers and scale insects, and common diseases include anthracnose and black coal disease. After discovering diseases and insect pests, diseased leaves and branches should be cleaned up promptly, and pesticide spraying should be used for prevention and control.
