What should I do if the tips of the red maple leaves dry up and fall off the leaves in spring?

Red maple likes sunlight, is suitable for warm and humid climate, is afraid of scorching sun exposure, is more cold-tolerant, slightly drought-tolerant, not waterlogging-resistant, and is suitable for growing in fertile and loose well-drained soil. It is a neutral shade tree species, which will cause the leaf edge to roll in the dry and hot wind in summer, and the high temperature sunburn will also damage the bark.

Depending on the cause, there may be several reasons for dry branches.

1. Dry leaf curls caused by high temperature and strong light burns.

Cause of occurrence. Red maple is a neutral shade tree species, especially on dog days, if it is blown by hot and dry winds, it will cause leaf edge rolling, and severe high temperature and sunburn will also damage the bark.

Solution. 1. Build a shade net, and the shade net should be more than 50 cm at the top of the red maple.

2. When planting plants, it is best to consider planting them in a slightly cool place.

2. Caused by fungal diseases.

Characteristics of dry leaf manifestations caused by fungi.

Dry leaves caused by fungi generally have the following characteristics: the leaf tip and the leaf edge of the upper part of the leaf will produce water-stained green spots in the early stage of the disease, and with the development of the disease, the diseased part will appear scorched, and gradually expand to the lower and inner part of the leaf, and finally the upper half of the leaf will die. The junction between the diseased part and the healthy part is russet, the middle is dark red, and finally the whole leaf 3 4 is dead, only the base of the leaf is green, the tip of the dead part of the leaf is curled, grayish-white, and the whole leaf is like a fire.

Solution. 1. Cut off the diseased leaves before the disease spreads at the beginning of the disease to reduce the source of reinfection;

2. Spray 800-1000 times of Royal Forest Fungus or Pendritic Fungi + 1000 times of Lurun 1000 times of liquid on the leaves, and spray 2-3 times alternately at an interval of 7-10 days.

3. The root system is weak and the water is insufficient.

Characteristics of manifestations caused by weak roots.

Generally, it is easy to appear in the newly transplanted red maple in the current year or transplanted within a year. Generally, the newly transplanted red maple in spring needs a recovery process, if the root system does not recover before the arrival of the summer high temperature season, it is easy to cause the imbalance of water budget and cause the leaves to dry up, and finally cause the dry branches to die.

Solution. 1. First of all, check whether there is deep planting water during planting;

2. For dry or overlapping branches, it is best to thin branches and leaves;

3. To promote the rapid growth of the root system, it is recommended to water the root of Triumgen Bido to promote the rapid growth of the root system.

After spring, the tips of the red maple dry up and fall leaves, and I personally think that it is mainly caused by the lack of corresponding water or fertilizers and other factors.

Resolution. 1. Cut off the scorched leaves.

2. Check whether the roots are rotten and cut off the rotten parts.

3. Change the soil again, pour fungicide solution, and sterilize the soil and roots.

4. Astigmatism breeding, dry and then watering.

1. Reduce watering: If it is caused by too much watering and obstructing the respiration of the root system, it is necessary to drain the stagnant water as soon as possible, strengthen ventilation, evaporate water, and reduce the amount of watering in the later stage. 2. Increase light:

If it is caused by a lack of light, it is necessary to increase the light, get more sunlight, and ensure that you receive more than 8 hours of light every day. 3. Reasonable top dressing: If there is fertilizer damage, remove the pot and trim the roots as soon as possible and re-cultivate.

4. Pruning in time: If the leaves are wilting in the changing season, pruning can be carried out in time.

After the car, the red maple leaves are not dry, you can water a little or add some nutrient solution.

See if you need some nutrient solution!

The reasons for the dry hair curls of red maple leaves are as follows:1. The light is too strong: the dry hair curls of the red maple leaves may be sunburned by strong light, so they should be shaded in time and placed in a semi-shaded and ventilated place.

2. Lack of water: If you do not water for a long time, the soil is dry and water-deficient, which can easily lead to yellow leaves and rolled leaves, so you should replenish water as soon as possible, and it is best to water thoroughly.

3. Environmental discomfort: If the leaves are prone to curls and yellow leaves in a closed and dry environment for a long time, ventilation should be strengthened and water should be sprayed frequently.

4. Insect pests: When red maple is infected with insect pests, the leaves are prone to curls and dry up, so they should be sprayed in time.

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.

The following three points are summarized.

1. Too strong light Although plants can only grow better with sufficient light, but if the maple tree is often exposed to the sun, it is easy to be burned, and the leaves are dry and yellow.

2. Improper watering Sometimes overwatering does not help the plants in the slightest, and even has the opposite effect, I suggest that when you are watering, it is best to ensure that the potting soil is moist, of course, when the weather is hot, you can spray the leaves with a watering can from time to time, so as to increase the humidity of the environment.

3. Fertilizer factors During the growth of maple trees, if the fertilization is improper, it may also lead to the phenomenon of fat yellowing, I suggest that you fertilize 1 to 2 times a month when fertilizing, it is best to choose nitrogen, phosphorus and potassium fertilizer to mix fertilizer in proportion, so that its growth is relatively large, or Trim special fertilizer.

Maple leaves, why did you suddenly start drying? Because he may be dehydrated, he has not been exposed to water for a long time.

If it's dry, it's supposed to be out of water, and if it blows out, you should put it out there and let it rain.

1.High temperature and strong light: when the leaves of red maple are dry, it may be due to the reason of high temperature and strong light, red maple belongs to the shade of the tree species, especially in summer, if it is blown by dry and hot wind, it will cause the leaves to dry up, and the severe high temperature environment will also damage the surface of the tree.

2.Lack of water: When the leaves of red maple are dry, it may be due to the lack of moisture in its roots, resulting in the problem of dead leaves, which generally occurs when it is newly transplanted or transplanted within a year.

The leaves of the red maple are dried up.

1.Avoid light treatment: When the high temperature dries up, you can put the red maple in a cool place in the middle hall, which can avoid direct sunlight, prevent the leaves from drying up, and also help maintain the nutrients required by the leaves.

2.Watering in time: If the red maple is dry due to insufficient water, it should be treated with reasonable watering, and regular watering according to its growth cycle can maintain the water required for the growth of the red maple.

1. Red maple leaves wilt generally appear in the change of seasons, the change of seasons leads to the change of temperature difference, red maple is a relatively valuable foliage tree, and the rapid change of temperature may make it unadaptable. During the change of seasons, daily management should be strengthened, especially when spring turns to summer, and the light time and intensity are increased, so it is recommended to carry out appropriate shading treatment and frequent watering.

2. The red maple is easy to wither the leaves soon after planting, which may be that the red maple tree is not suitable for the local water and soil environment. It is recommended to first understand the living habits of the red maple tree, and then change it according to the living habits of the red maple tree.

3. It may be that the light intensity is too large, and a large amount of water in the plant is evaporated, so the leaves are wilted. Potted plants should be moved to a location with suitable temperature and good ventilation immediately, taking care to shade the sun and replenishing water at the same time.

4. It may also be infected with pests and diseases. Remove the withered leaves in time, or prune the branches, and spray the drug for **, and at the same time add some fertilizer to the plant to calm the Zen, improve the ability to resist pests and diseases, and wait for the red maple to rejuvenate the skin.

The drying of the leaves of the red maple may be caused by too much light, so when the light is too strong in summer, it is necessary to build a shade net above the red maple. It can also be caused by a lack of water in the root system, so you need to water the soil to moisturize. The lack of nutrients during the growth period of red maple will also lead to the drying of leaves, and compound fertilizer needs to be applied every 1 month during the growth period of red maple to maintain the normal growth of red maple.

The cause of the dry leaves of the red maple.

Red maple needs sufficient light during the growth process, but it is not tolerant to direct sunlight, and if it is exposed to direct sunlight for a long time, it will cause dehydration and dryness in the middle of the red maple leaves. Therefore, when the light is too strong in summer, it is necessary to build a shade net above the red maple to weaken the intensity of the light, and the potted red maple can be moved to a ventilated and cool place for maintenance.

Red maple in the growth period of the need for water is larger, especially in the summer high temperature season, during this period need to be watered every 2 3 days, if the soil is in a dry state for a long time, it is easy to make the red maple leaves wilt, will reduce its ornamental value.

Red maple is suitable for growing in a fertile environment, need to apply an appropriate amount of fertilizer to maintain the normal growth of red maple, if not fertilized for a long time, the lack of nutrients in the soil, will make the red maple leaves appear yellow and dry. Therefore, in the growth process of red maple, compound fertilizer needs to be applied every 1 month to supplement the nutrients required for the growth of red maple.

Red maple is susceptible to gray mold and leaf blight during the growth period, and the leaves of red maple will dry up after the disease. At this time, it is necessary to prune off the more seriously diseased leaves, and spray chlorothalonil solution once to kill the bacteria in the soil and restore the growth of red maple as soon as possible.
