Can you grow red bayberry trees in the north?

Myrica rubra is not suitable for growing in the north. Because the basic moisture conditions and temperatures in the north cannot be reached, even if there is, it is impossible to grow normally. Myrica rubra likes a warm, humid, cloudy climate. Intolerant of strong light, not cold. Mountain north or east, deep soil layer, loose fertile, good drainage acid soil planting is appropriate.

1) The planting time. Spring planting and autumn planting. Spring planting is from February to early April, autumn planting is from September to November. Spring planting is generally good. Yunnan, Guizhou, Guangxi, Sichuan, Hunan, Jiangxi, Guangdong and Fujian can also be planted from October to late March of the following year.

2. Planting density. It is advisable to plant 33 ~42 plants per mu with row spacing of 4m×4m or 4m×5m. The ratio of male to female is 100:1. If there are wild Myrica rubra in the area, male plants can not be matched.

3. Apply basal fertilizer. Planting holes 80×80×60cm, applying compost 50kg or manure 25-30kg or cake fertilizer 3- 4 kg per hole, adding calcium superphosphate 1kg, covering with fertile topsoil 15-20cm thick.

4. Planting. When planting, the seedlings are placed in the center of the hole, the root system is stretched, the seedlings are righted, and then fine soil is added, and the seedlings are tamped with a foot or a hoe. Pouring enough root fixing water, covering the top with subsoil 20-30cm higher than the ground, and covering the joint under the ground is appropriate. After seedling planting, the high temperature season in July and August should be loosened, watered and covered in time to reduce water evaporation.

1. The main disease of Myrica rubra is brown spot, also known as anthracnose, which is an important disease that damages the leaves of Myrica rubra. Serious disease causes a large number of leaves, causing insufficient nutrition of the tree, and finally leads to the decline of fruit quality. The pathogen overwinters in ascocarp in diseased leaves, and the disease occurs in late March to early April of the next year. The disease is more serious in plots shaded by tree crown, insufficient sunlight, poor soil, lack of potassium fertilizer and organic fertilizer.

Control methods:

(1) Clear the garden. Autumn and winter season, combined with pruning, concentrated burning or deep burial of diseased leaves, disease branches.

(2) Strengthen cultivation management: In the management of growing season, the management of soil, fertilizer and water should be strengthened reasonably, and the ventilation and light transmission conditions of trees should be improved in combination with pruning. (3) Spray control: At the early stage of disease, i.e. after flowering, spray 1500g of Bome 1 degree stone sulfur mixture per mu for control.

2. Whitefly is the main pest of Myrica rubra, which damages young shoot leaves, and occurs more seriously in June and July.

Control methods:

(1) Protect and utilize natural enemies such as ladybugs and wasps, and implement insect control.

(2) During winter and spring pruning, cut off dead branches and branches with high insect density, and burn them intensively to reduce insect sources.

(3) Spraying control: In July when the pest occurs seriously, spraying 4.5% cypermethrin EC per mu can achieve good results.
