1. Soil

It is appropriate to use loose and permeable, unobstructed drainage, rich in organic matter fertile acid culture soil or rotten leaf soil. The hardening of basin soil or pH value higher than 7.5 will also cause yellowing of plant leaves, serious poor growth and decrease of sprouting ability, and affect bud regeneration, and even shorten its cultivation life. For this reason, small plants should change pots once a year, large plants can change soil once every two years, and loosen the soil once a month during the growing season, especially after heavy rain, flowerpots should be checked in time, water should be poured out as soon as possible, and loose soil should be replaced as soon as possible. Potted plants, the annual time to turn the pot to change soil, it is best to arrange after the spring to sprout before it is more appropriate.

2. Lighting

The light requirement of Ping an tree varies with age. It is shade tolerant when young, and the 3-year-old and 5-year-old plants grow faster in shade, while the 6-and 10-year-old plants require plenty of sunlight. Potted plants into the summer, can not be given full light, can be placed in the shade of trees or under the shade, give about 50% of the scattered light, sooner or later let it fully see the light, then the growth is better. If the light is too strong, it is easy to cause leaf yellowing and affect the ornamental effect.

3. Temperature

The suitable temperature for its growth is from 20 ℃ to 30 ℃. Young trees are not tolerant to low temperature. If frost lasts for more than 5 days, the plants maintained or cultivated in the open field can easily lead to bark cracking, branches and leaves withering, and even the whole plant being frozen to death. Whether it is a small number of plants in family pot or large-scale production and management cultivation, the greenhouse temperature should be maintained at no less than 5 ℃ in winter in order to keep the leaves green and beautiful all the time. Larger plants can endure a low temperature of about 0 ℃ for a short time when there is no cold wind in the greenhouse.

4. Watering

Ping an trees like to be wet, usually wait for the basin soil surface to be watered when half of the soil is dry, and often spray water or spray on the leaves when the weather is dry. Wait for about half of the basin soil to dry before watering in winter. Ping an tree likes the environment with high air humidity and general relative humidity. Only when it is more than 80% can it grow vigorously. In summer or dry autumn, or even put indoors in winter, you should often spray water on the leaves to create a more humid space environment. If there is stagnant water in the basin, it is easy to cause root rot.

5. Fertilizer

Ping an tree has plump plants, large leaves and prosperous growth, so it needs a large amount of fertilizer. Potted safe trees not only require fertile soil, but also apply thin cake fertilizer or alum once a month from mid-spring to early autumn. After entering autumn, phosphate and potassium fertilizer should be applied twice continuously, such as 0.3% potassium dihydrogen phosphate solution, so as to increase the cold resistance of the plant, promote the young shoots to Lignification as early as possible, so that they can survive the winter safely. All forms of topdressing should be stopped in winter to prevent fertilizer from injuring the roots and causing the leaves to yellowing or scorching off, otherwise it is difficult to restore the original appearance of the plant.

6. Change the basin

Small trees of Ping an tree should change their pots once a year, and large trees can change pots once every two years. It is the appropriate time to change pots after coming out of the room in spring and before sprouting. Every time you change the basin, you need to get rid of about 1 pound 3 of the lodging soil and replace the loose and fertile new soil and base fertilizer. Usually need to loosen the topsoil once a month, especially after the heavy rain to check the flowerpot, found that stagnant water in the pot should be poured as soon as possible, and replace the loose soil.

7. Disease

Ping an tree is prone to brown root disease in autumn. at the initial stage of the disease, it can be sprayed with 50% methyl thiophanate sulfur suspension 800 times or 50% Gen Yuling wettable powder 800 times for control. Seriously diseased plants and plants withered due to disease should be uprooted and burned and disinfected with carbendazim 600 times solution.

Note:

1. A small number of diseased leaves should be removed and burned in time to avoid yellowing and withering of the whole leaves, resulting in a large number of fallen leaves.

2. If there is stagnant water in the basin soil, it is easy to lead to plant yellowing, lower leaves yellowing and falling off, and in serious cases, it will cause rotten roots and death. If the soil adhesion is heavy or the acidity is low, it will cause the leaves of cultivated plants to yellowing and sprout regeneration to decrease, thus affecting the growth life of plants.

3. Whether in the adaptation period or in the overwintering dormant period, watering should be controlled and no topdressing should be applied. The first topdressing should wait for the sprouts to grow rapidly. After entering autumn, phosphate and potassium fertilizer should be applied twice in a row, and all forms of topdressing should be stopped in winter to prevent fertilizer from harming the roots.
