Raising camellias and azaleas requires loose, fertile, acidic soil, which can be prepared from leaf mold soil, garden soil and river sand. Maintain long-term exposure to sunlight, but avoid exposure to the sun. Watering can be done after the soil surface is dry, but the amount of water should not be too large. Apply phosphorus fertilizer once a month before flowering, and add nitrogen and phosphorus fertilizer after the flowers fade. There are two methods of propagation: cutting and grafting. If you encounter pests and diseases, you need to remove the diseased branches and leaves and spray them with pesticides.

1. Breeding methods

1. Soil: Camellia azalea is suitable for growing in loose, fertile, acidic soil. It can be prepared with leaf mold soil, garden soil and river sand, and a flowerpot with good permeability should be used.

2. Light: The growth of camellia and azalea cannot be separated from sufficient light. It is necessary to ensure long-term sunlight exposure every day, but it needs to be shaded in summer and cannot be exposed to strong light, otherwise the leaves will turn yellow and dry.

3. Watering: Camellia azalea prefers a humid environment . Water when the surface of the soil is dry but still moist inside. Do not wait until it is completely dry. The amount of water should not be too large to avoid water accumulation and flooding of the roots.

4. Fertilization: Before the camellias and azaleas bloom, phosphate fertilizer should be applied once a month. After the flowers fade, nitrogen and phosphorus compound fertilizers should be added to make up for the nutrients consumed during the flowering period. In summer and winter, the growth is relatively slow or enters the dormant period, so it is not suitable to fertilize.

2. Reproduction skills

1 , Cutting: Cutting is a common propagation method for camellia and azalea, and is usually carried out from May to June. Cut a relatively thick branch, between 5-8 cm in length, remove the lower leaves, and apply indolebutyric acid on the bottom to facilitate rooting. Then the cuttings are placed in loose and breathable acidic soil, and the temperature is controlled at about 20-25°C, and roots will soon take root.

2. Grafting: For varieties that are more difficult to survive, grafting can also be used. Cut the bottom of the scion into a wedge shape and insert it into the gap in the rootstock. Tie the fit tightly and cover with a plastic bag to keep the air moist.

3. Pest and disease control

1 , Disease: Leaf spot is relatively common, and the leaves will turn yellow and dry after the disease occurs. The diseased leaves need to be removed and sprayed with thiophanate-methyl solution for control.

2. Insect pests: Aphids are the main pests, causing leaves to curl and become brittle, and also affect flowering. It is necessary to capture the adults and kill the eggs with lime sulfur mixture.
