Camellia breeding method

Choose a site from September to October, apply plantar manure, plow and level, choose strong-growing, disease-free camellia branches as cuttings, cut them into 10 cm long, remove the lower leaves, and insert them with the cut. On the nursery border. When inserting, the line spacing is 18-21 cm, and the plant spacing is 6-9 cm. After inserting, water, and then cover tightly with plastic film, and cover with reed curtain to shade, timely topdressing, watering, and loosening the soil to keep the seedlings moist. Take root after 2 to 3 months. When the branches are as high as 50-80 cm, they can be transplanted and planted.

Camellia is commonly grown in pot, because it grows slowly, has a small root system, and has more small hairy roots. Change the basin once every three years, and it is advisable to fertilize it in the beginning of summer and prevent excessive watering. Fertilizers are mainly 60% grass charcoal soil, 30% leaf humus soil, and 10% coarse sand. Pay attention to ventilation.When the flower buds can be distinguished, 1 to 3 flower buds are left on each branch, so that the excess will not be removed

Excessive consumption of nutrients makes the flowers small but not beautiful. Camellia is good for cultivating into a low shape, plus applying thin alum fertilizer every 10 days, it will still be full of smiles and sultry feelings when it blooms.

Camellia can be planted in gardens in the south of the Yangtze River, and potted in the north, and the potting soil must be prevented from freezing. Due to the growth temperature of camellia, it is appropriate to be around 25°C during the day and no less than 16°C at night, and the pot soil is required to be dry, avoid moisture, and have good drainage. Because the camellia loves acid and alkali, the potting soil should be mixed and composted in the ratio of 4 parts of sandy loam soil, 3 parts of humus soil, and 3 parts of compost soil.

The camellia must be watered more after it is potted, and then watered again every 1 to 2 days. The whitening of the pot soil is a sign of watering. But if the pot soil is too wet for a long time, it is easy to cause rotten roots. Evaporation is large in summer and more water is required. If you see yellow leaves, the soil is not acidic enough, so 0.2% to 0.3% ferrous sulfate (black vitriol) water should be watered every 15 to 20 days.

Camellia pest control

Camellia is mostly infested by scale insects. If the leaves are withered and yellow, the plant growth is weak, and scale insects gather on the backs and branches of the leaves. They use filamentous mouthparts to penetrate the tissues of the branches and leaves of the camellia to absorb nutrients and secrete wax, causing coal pollution. They should be in their active period. (April to May and July to August) Stone sulphur mixture or rosin mixture. If it occurs in a small amount, it can be manually scraped off.

Camellia pests also include “caterpillars”, “tea moths”, “tea halphis”, etc., which can be sprayed with insecticides such as 50% oxidized dimethoate milk or 80% dichlorvos cream 1000 times. Camellia diseases include “tea round spot”, “algal spot”, and “anthracnose”. For bacterial diseases, 500 times potassium permanganate solution or 1000 times agricultural streptomycin can be used to prevent and control; for epidemic diseases, 600-800 times solution of 25% retinoxin can be sprayed, or 75% dixon or 50% carbendazim can be used. Irrigate roots with liquid or 70% thiophanate methyl 700-800 times liquid, once every 10-15 days, 3 times in total.
