Why are the new leaves of plants wrinkled?

Foliage of new leaves of foliage plants is likely to be caused by improper maintenance. If it is not fertilized in time during the breeding period, the newly grown leaves will not be able to absorb nutrients, which will affect its growth and become wrinkled. After its germination, it is also prone to wrinkles if the humidity is insufficient, so it needs to be replenished with water. There is the sun, the new growth belongs to the tender leaves, can not be exposed to the sun, so burns will wrinkle.

Mite infestation. Recently, there has been a phenomenon of new leaf shrinkage in a variety of crops, and vegetable farmers have different views on the causes of this phenomenon. Some suspect that it is caused by thrips or mites, while others think it is caused by viruses. In fact, the main reasons for the shrinkage of new leaves of vegetables can be attributed to three points: mite invasion, viral disease and hormone poisoning. The manifestation of mite attack.

Leaf wrinkle, this kind of curling leaf, is often caused by comprehensive factors. Soil hardening, salinization, excessive moisture and other factors lead to poor root growth, high temperature, poor ventilation, uncoordinated fertility, and side effects of pesticide use, which exist more or less in the field at present.

How to solve the problem of curling and wrinkling the new leaves of the rich tree?

1. If the leaves are curled and wrinkled caused by the lack of moisture, they need to be watered immediately, and then carefully maintained and watered. Spring and autumn can be watered every other week, and once a day in summer. The rich tree will be dormant in winter. Do not need a lot of water, watering every 15 to 20 days, each watering to control the amount of water, to avoid stagnant water rotten roots, but also cause leaves curl wrinkle, and may even wither and die.

2. Treatment method: change the soil of the rich tree, replace the brand-new basin soil and re-maintain it, and cut off its old, weak and disabled roots when changing the soil. Fourth, excessive fertilization for the maintenance of wealth trees requires reasonable fertilization, and thin liquid fertilizer can be applied every 20 days in the growing season. Once too much fertilizer is applied and the concentration of fertilizer is too high, it will burn the roots of the plant and cause its new leaves to curl.

3. In this case, the solution is very simple, that is, immediately water the rich tree, then carefully maintain it, change the watering method, and it will return to normal after a period of time. Generally speaking, rich trees can be watered every other week in spring and autumn, once a day in summer and every 15-20 days in winter.

What if the holly bought during the Spring Festival has grown leaves?

Please make sure that holly gets the right amount of water and proper light to maintain its healthy growth.

After properly watering holly leaves, the demand for water will increase. In order to maintain a suitable growth environment, appropriate watering is needed to ensure that the soil remains slightly wet. At high temperature in summer, watering frequency should be increased to avoid yellowing or shedding of leaves caused by soil dryness, affecting growth. Timely fertilization with the growth of leaves, holly will consume more nutrients.

The plant does not have a strict demand for water and fertilizer, but it needs to be watered regularly during its growth.

Increase the amount of water after the leaves of American holly grow out, the water consumption will also increase, it likes the humid growth environment, so its drought resistance is poor, especially in the hot summer, it needs to be watered frequently to ensure adequate water. If the soil is dry for a long time, yellow leaves and fallen leaves are likely to appear, hindering the growth and germination in the later stage. However, be careful not to have too much water, it is just wet and there is no water.

However, pay attention to the amount of water is not too large, wet on the line, can not accumulate water. Timely fertilizing the growth of North American holly consumes more nutrients, so topdressing should be carried out in time after growing leaves. Fertilizer species can choose phosphate fertilizer or compound fertilizer, which can supplement the necessary nutrients and promote more vigorous growth. Fertilizer is usually applied two or three times. If the plants are not fertilized for a long time, the growth will become weaker and the number of blossoms and fruits will be reduced.

Properly watered the new leaves of North American holly need more water to maintain growth, so the soil should be kept moist. In the period of high temperature in summer, the watering frequency should be increased to avoid yellowing or shedding of leaves caused by drought. At the same time, it is necessary to avoid stagnant water caused by too much water, so as to avoid root damage.
