Why the leaves of rich trees turn yellow and its prevention and treatment? What are the key points of planting techniques?

Small trees of the kapok family, 4-5 m tall, with a loose crown, young branches chestnut brown, glabrous. Leaflets shortly stipitate or subsessile. Flower solitary branch apical leaf axil; pedicel stout, yellow stellate velutinous, deciduous; calyx cup-shaped, subleathery; petals yellowish green, narrowly lanceolate to linear, upper part revolute. During the flowering period from May to November, the fruit matured successively, and the seeds germinated naturally after falling to the ground. So, the cause and prevention of the yellowing leaves of the rich tree? What are the key points of planting rich trees?

I. the causes and prevention of yellowing of the leaves of rich trees.

1. Overwatering

The root system of the rich tree is relatively weak, and it will be affected by too much water and too little water. In the maintenance process, it is necessary to grasp the slightly dry water content, watering should not be too much.

2. Lighting

The rich tree is also a kind of tree species with high demand for sunlight, and proper sunlight can ensure its vitality. If the plant is yellowed when it is placed in the shade for a long time, it needs to be moved to a place where the sun can be exposed.

3. Too much fertilizer

Excessive fertilization causes the roots of the rich tree to rot, remove the plant from the pot, clean up the rotten part, replace it with new soil, and replant it. Or through watering, dilute the nutrients in the soil, reduce fertility.

4. Exposure to the sun

In summer, if you put cool flowers (such as cyclamen, Golden Bell upside down, four Seasons Begonia) in a high temperature place to let the strong light shine directly, it is very easy to cause the young leaf tip and leaf edge to scorch, or the leaf yellow to fall off.

5. Lose weight for a long time

There is no application of ammonia fertilizer or no change of soil for a long time, and there is a lack of nitrogen and other nutrients in the soil, resulting in thin branches and leaves and thin and yellow leaves.

Second, what are the key points of planting rich trees?

1. The climate of growth

The rich trees like the high temperature and humidity climate, the cold tolerance is poor, the seedlings avoid frost, the adult trees can withstand light frost and long-term 5-6C low temperature, South China can survive the winter in the open field, and the north should be moved into the greenhouse in winter.

2. Suitable soil

Like fertile and loose, permeable and water-retaining sandy soil, acidic soil, avoid alkaline soil or clayey soil, more resistant to water and moisture, but also slightly resistant to drought.

3. Place of origin

Originally from Central America, Mexico to Costa Rica. Cultivated in Xishuangbanna, Yunnan, China. The pericarp can be eaten when it is not ripe, and the seeds can be fried.

4. Mode of reproduction

Melon and chestnut trees can be propagated by sowing or cutting.
