What to do if the leaves of the red maple tree wither, what is the reason why all the leaves of the

The temperature is high, the light intensity is high, the humidity is small, the tip of the red maple leaf will dry up, the leaf edge will dry up, and the leaves will turn green. In general, it is necessary to water more often, keep the soil moist, and have proper shade to reduce sun burn.

Red maple originally grew in a warm and humid environment, and has been widely planted in the Yangtze River basin and other places. The following will tell you about the specific red maple planting method and the planting method of red maple trees.

In order to promote the growth of saplings, it is necessary to apply fertilizer at the right time and in the right amount. In early spring, hydrogen fertilizer was mainly applied, and the ratio of hydrogen, phosphorus and potassium was 6:l:

3. The principle of fertilization is "thin fertilizer and more application", which is applied once every 7-10 days. In late spring and summer, in order to increase the organic composition of the soil, the main thing is to apply well-rotted pig pen fertilizer. After entering autumn, it is advisable to apply well-rotted vegetable cakes, oil cakes, soybean cakes or compound fertilizers, which can be applied by holes around the roots or by ring.

The ratio of phosphorus to potassium is 2:3:5.

When the seedlings grow to a certain extent, they need to accept photosynthesis to the maximum, and the garden or pot culture should be careful not to keep it in the shade, and it can be properly shaded in the hot summer. If it is not a single plant, there are also planting density considerations. Generally, if the dry diameter is less than 1 cm, the plant row spacing is meters, and the plant row spacing of the dry diameter of 1-2 cm is meters.

When transplanting, the seedlings need to be pruned first, and the middle roots, some of the overly long and slender roots and long branches should be removed. Seedlings with a thickness of more than 2 cm must be transplanted with mud balls.

There are three types of pests that harm red maple. Underground pests such as grubs and mole crickets gnaw on the roots and basal stems of seedlings, which can easily cause seedlings to die. You can use 50 cans of phoxanthion EC or 1000 times of Lesben liquid, pour the roots or mix fine soil to sprinkle.

Pests that infest branches and leaves, such as beetles, stinging moths, aphids, etc., often eat red maple leaves, resulting in poor growth of seedlings, and need to use avermectin, trapping, and dimethoate 800-1000 times for spraying. Dry-boring pests such as beetle, heartworm and other harm to the branches of red maple, resulting in the death of red maple seedlings and even the whole plant, it is necessary to use 2000-3000 times to spray inulin, green kung fu and so on, or inject pesticides such as methamidophos and dichlorvos into the branches at the mouth of the insect channel and seal them with sticky mud.

1. If it is caused by an infectious disease, you can cut off the dry branches and leaves, and spray carbendazim or chlorothalonil solution. 2. Strong light exposure: If it is caused by strong light exposure, it can be properly shaded and avoid direct strong light.

3. Lack of water: If it is caused by insufficient water, it can be watered in time. 4. Nutritional deficiencies:

If it is caused by insufficient nutrition, basal fertilizer can be applied in advance, and thin fertilizer can be applied according to different growth stages.

Pests and diseases.

The red maple comes from the Latin source: Acer palmatum'atropurpureum', also known as bai red maple, is a variant of maple family du chicken paw maple, is a deciduous tree, produced in Zhejiang, Anhui, Jiangsu, Henan, Jiangxi, Shanghai and other places.

The red maple tree is 2-8 meters high, and the branches are mostly slender and smooth, with purple-red tinges.

Normal, the old leaves, all the leaves, will grow new leaves. The old leaves can be plucked in Futian, and new leaves with stronger ornamental properties can grow after half a month. Maple likes moist, semi-shaded; Avoid western sunbathing. Attention should be paid to the place of placement.

1.Infection Cause: The leaves of the red maple are dry and wilted, so it is necessary to judge whether it is infected with the disease. If the red maple is not properly managed, it may be infected with leaf blight, causing a large number of leaves to wither and fall, affecting the normal growth of the red maple tree.

2.Bright light exposure Causes: After entering the hot summer, as the temperature rises and the sun's rays intensify, the leaves of the red maple may be burned.

3.Lack of water Reason: Red maple needs water during cultivation management, and if it is not watered enough for a long time, it will lead to soil drought.

4.Insufficient nutrients Causes: Red maple trees should ensure adequate nutrition during the growing season, if insufficient fertilization and lack of nutrients, it will lead to leaf wilting.

The leaves of the red maple are wilted, mainly because of the lack of water in the ground where the red maple grows.
