How to raise potted camellias?

Camellia is a traditional ornamental flower in China, also known as Camellia. It is the general name of many plants and horticultural varieties of Camellia in Theaceae. Because of its beautiful shape, bright green leaves and colorful flowers, camellias are cherished by the horticultural circles all over the world. There are many kinds of flowers, such as red, purple, white and yellow. Let's take a look at how to raise potted camellias.

Growth habits of Camellia

Camellia fear the wind and enjoy the sun, high terrain, good ventilation, warm and moist, good drainage, loose and fertile sandy loam, loess or humus. PH5.5~6.5 is the best. The optimum temperature is between 20 and 32 ℃, stop growing when the temperature is above 29 ℃, and the leaves will be anxious at 35 ℃, which requires a certain temperature difference. The environmental humidity is more than 70%, and most varieties can withstand the low temperature of-8 ℃. In the south of Huaihe River, they can survive the winter naturally and like acid soil, and require good air permeability. The root hair is developed and can usually be cultivated with a mixture of peat, sawn wood, laterite, humic soil or above.

Propagation methods of Camellia

1. Cutting: cutting propagation is mostly carried out from May to June. It is appropriate to choose strong annual branches as cuttings, cut them into 10-12 cm long, leave the upper 2-3 leaves, and remove the lower leaves. Insert into Susha seedbed or flowerpot. River sand or loose mountain soil can be used as basin soil. After planting, pour water thoroughly, spray water properly later, keep the soil moist, and provide shade, it can take root in about 60-70 days.

2. High pressure: the high branch pressing is mostly carried out between April and May by selecting the annual branches, peeling the ring in the high pressure part with a width of 0.5 cm, and wrapping the ring with a moderate size of plastic film with a length of 10-15 cm. First, tie up the lower mouth, inside the moist culture soil, often keep the soil moist, and then fasten the upper part of the mouth, and then cut it off and plant it.

How to grow potted camellias?

1. Soil: soil is the foundation of camellia growth, and all nutrients of camellias are obtained from soil, so there is a high demand for soil. Generally, the soil contains high humus, PH value is between 5 and 6.5, and is slightly acidic. The best soil configuration is 50% of mountain soil, 40% of sawdust or edible fungus residue, 10% of cake fertilizer or livestock manure and 10% of phosphorus fertilizer.

2, temperature: the suitable growth temperature of camellia is 18-25 degrees Celsius, the temperature of the environment is too high or too low is not conducive to the growth of camellias, especially in winter, move the plants to the indoor growth, move the plants to the balcony at noon, and pay attention to sunscreen in summer to prevent the temperature from being too high.

3. Watering: camellias like to grow in a humid environment, so we should mainly water camellias, but we should pay attention to keeping the soil not too dry or too wet, generally watering more in spring and summer, which is also beneficial to the growth of camellias. In winter, we should pay attention to less watering, and it is better to water every two to three days.

4. Fertilization: Camellia is a fertilizer-loving plant, so in the process of breeding, pay attention to fertilization, generally in the growing period, add phosphorus and potassium fertilizer, which is also conducive to the growth of camellia, so as to make the flowers bloom more luxuriantly, at the same time, the main fertilization should not be too much.

5. Pruning: the pruning of camellias is also very important. When the buds of camellias are dense, regular pruning is recommended to cut off weak branches and arrange buds, which can also promote the absorption of nutrients by camellias.

6. Diseases and insect pests: Camellia is very easy to produce diseases and insect pests, generally there are two kinds of diseases and insect pests, black mold and anthrax. Pay attention to spraying some medicine to eliminate diseases and insect pests during the period of diseases and insect pests, which can play a good role in promoting growth.

7. Turning the pot: it is recommended to turn the pot and change the soil once after potted for one year, so as to provide a better growth environment, and the new pot should be larger than the old one to facilitate the expansion and development of the root system. The time to turn the basin should be in spring, April or autumn. In the process, try to remove some of the old roots, replace them with fertile and loose new soil, and combine them with base fertilizer.
