How to raise a safe tree? Introduction to the Culture method of Ping an Tree

The peace tree means auspiciousness, symbolizes peace and happiness, and has a happy life. At the same time, Ping an tree can emit the smell of correcting peculiar smell and purifying the air, so it is deeply loved by many family companies. But many people raise safe trees, and after a period of time, the leaves wither and slowly wither, and the leaves turn yellow. Therefore, there are many techniques and precautions for the cultivation of Ping an trees. Here are the flowers and plants to share with you the cultivation methods of Ping an trees:

one。 Introduction to the Culture method of Ping an Tree

Ping an tree likes light and shade, warmth and heat, and is not resistant to drought, stagnant water, cold and dry air. It is commonly cultivated in acid sandy soil which is loose and fertile, good drainage and rich in organic matter. As long as loose and fertile, good drainage, partial acidity can be. Generally do not need watering, spray water on the leaves every 2 to 3 days, water thoroughly once a week or so. Especially after the beginning of autumn, we should water less and spray more. Stagnant water will cause leaves to fall off, plants withered and yellow, and in serious cases, roots will rot. Here is a detailed description of how to raise Ping an trees:

1. Spring management

Potted safe trees had better be moved out of the room before and after Ching Ming Festival in spring. Due to the repeated seasonal temperature before and after the Qingming Festival, it is necessary to pay attention to the damage to plants caused by the cold in late spring. In addition to fertile soil and sufficient basal fertilizer, potted safe trees in spring can be topdressing dilute liquid fertilizer or compound fertilizer once a month from mid-spring to early autumn. It is prone to anthracnose and brown spot in spring, which can be prevented with 1% Bordeaux solution, and a small number of diseased leaves can be removed and burned in time.

2. Summer management

When the temperature is high and the light is strong in summer, potted safe trees need to be protected from the light. If the light is too strong, it is easy to cause the leaves to turn yellow. When the temperature exceeds 32 ℃, it is often necessary to spray water to the leaf surface and its surroundings to humidify and cool down, so that it can maintain exuberant growth. Apply rarefied liquid fertilizer or compound fertilizer once a month. There are many leaf rollers in summer, which can be sprayed with pyrethroid.

3. Autumn management

After entering the autumn, the temperature drops gradually, potted Ping an trees should control watering, gradually reduce the amount of water, and often spray water to the leaf surface and its surroundings, pour the basin and drain in time after rain to avoid stagnant water in the potted soil, resulting in yellowing leaves and even rotting roots and death. Before cooling in autumn, 0.2%-0.3% potassium dihydrogen phosphate solution should be applied twice in a row to increase the cold resistance of the plant, promote the Lignification of young shoots as early as possible, and ensure a safe winter.

4. Winter management

The safe tree is not resistant to cold, so it is best to move it indoors. The overwintering temperature should not be lower than 5 ℃. If the plants maintained or cultivated in the open field encounter frost for more than 5 days, it will easily lead to bark cracking, branches and leaves withering, or even the whole plant freezing to death. The larger plants could endure a low temperature of about 0 ℃ for a short time. In winter, watering should be controlled, the soil should be kept dry, and all forms of topdressing should be stopped to prevent fertilizer from injuring the roots, causing leaves to yellowing or scorching and shedding, so it is difficult to restore the original appearance of the plant.

6. Pest control

Aphids are easy to grow on the young leaves and new buds of Ping an tree. after spreading plant ash, rinse with clean water; spraying neem leaf juice can effectively kill insects; spray 2000 times of imidacloprid wettable powder.

two。 Matters needing attention in the Culture of Ping an Tree

1. In the process of breeding, if the branches and leaves are too dense, it is necessary to clean and remove the leaves and prune the branches regularly to keep them ventilated and ventilated.

2. Peace trees can be pruned all the year round, but spring or autumn is a period of exuberant growth of peace trees. if they are pruned at this time, it is easy to send out new branches. Prune some branches when the temperature is 20 ℃ in spring to increase the number of branches, but pay attention to the distance between the cut mouth and the bud hole of the Internode, otherwise it will lose water and cause the branches to wither. And the cut must be smooth and not tearing.

3. The main reason for the blackening of the leaves of Ping an trees is the damage caused by diseases and insect pests. Brown spot is the most important disease. This disease generally occurs in the case of poor indoor ventilation, hot and humid, or insufficient crossing the line. the leaves will produce some brown spots at the beginning, which will continue to expand later, and there will be a lot of black dots on the leaves, so that the leaves will slowly blacken and seriously fall down, and the disease is at its worst from April to May every year.
