The tips of the leaves of the azaleas began to turn red and black, like burnt, and began to curl, wh

It is recommended that you go to the gardener forum.

Some time ago, I wrote an article about the most delicate flowers in winter, there are azaleas, there may be some flower friends who will refute these flowers, because their rhododendrons have been cultivated for a long time, there are almost no problems, in fact, rhododendrons have been bred for many years, and it is really not easy to have problems in the later stage of breeding, but as long as you contact a friend of rhododendron, it may not be too good, so today we will take a look at the problem of this topic, what is going on with the rhododendron leaf tip turning black and zooming, how should I solve it.

The black burnt edge of the rhododendron leaf tip is associated with these points and needs attention.

1.The light is too strong.

If the potted azaleas are in the sun in the summer heat, then the long-term sun exposure will cause the leaves to dry out and sunburn, causing the leaves to turn black, so in summer, do not dry it directly, give it sun protection, and put it on the north side of the balcony. No matter what you usually do, you can't water it often, the flowers of this plant can also be cultivated, or it is relatively drought resistant, long-term watering is not a problem, but once you water too much, there will definitely be a problem, so when the leaf tips begin to turn black and scorch, you must deal with it in time, in order not to feed and not survive.

2.The potting soil is poor and the potting soil is agglomerate.

If the potting soil is not fertile enough to change the soil for a long time, the soil will not be fertile and will become more stiff, which is not conducive to the growth of the rhododendron root system, resulting in poor leaf development.

3. Watering too little and low air humidity.

In spring, autumn and summer, you need to water a little more, not only to make the potted soil moisture slightly moist, but also to increase a certain air humidity, if not watered in time, in addition to the drought for too long, the air humidity is not large enough, then its leaves will also change, there is a dry or black situation. Therefore, the following points should be paid attention to when preserving rhododendron potted plants. No matter which season the humidity is relatively high, it is very beneficial to the growth of plants, so it will be better to reproduce, but the indoor humidity is not very large, which will naturally cause the leaf tips to turn black and burn, and it is recommended to sprinkle water around the plants regularly when propagating.

For domesticated azaleas, the leaf tips are black and scorched, first of all, because of lack of water. It may also be that he is lacking some kind of nutrient and needs to be replenished in time.

The main reason is that the azaleas are often exposed to the sun, so the leaf tips will be black and scorched.

Summary. Hello dear, azalea leaves are caused by high temperatures and excessive sunlight like burnt. Rhododendron prefers cool and semi-shaded environments, where excessive temperatures and strong sunlight can cause the leaves to burn.

Try to place it in semi-shade and avoid exposure to strong sunlight. Rhododendron needs the right amount of water, but overwatering or lack of water can cause damage to the leaves. Make sure the soil is kept moderately moist, but not overwatered to avoid root rot.

Hello dear, rhododendron leaves like scorched high temperatures and excessive sunlight lead to the cavity of the cryptonucleus.

Rhododendron needs the right amount of water, but overwatering or lack of water can cause damage to the leaves. Make sure the soil is moderately moist, but not overwatered to avoid root rot.

What's going on with the azalea leaves?

Hello dear, azaleas prefer acidic soils, and if the soil is too alkaline, Li Sou may cause the leaves to burn. Check the pH of the soil, and if it is too high, consider using an acidic fertilizer or adding a special soil conditioner for rhododendrons. Excessive fertilization or high fertilizer concentrations may also cause the leaves to burn.

Follow the principle of using fertilizer in moderation, choose an acidic fertilizer suitable for rhododendrons, and apply it correctly to the wild according to the package instructions.

Rhododendron leaves are scorching, and it is recommended to check for the above possible problems and adjust light, moisture, soil and fertilizer management appropriately.

Dear, you can follow the above operation for treatment.

Dear, there are many reasons for the scorching foliage of azaleas, so let you follow the above methods to ensure the normal growth of azaleas.

Rhododendron can be infected with brown spot or erythema. Prevention and control can be carried out according to the onset symptoms of leaves.

Introduction: Rhododendron, one of the top ten famous flowers in China. Flower in the Shih Tzu, alias:

Yingshan red, mountain pomegranate, mountain heel, red heel, Jindalai, mountain cuckoo, red azalea, Yanshan red, Yanshan flower, Qingming flower, Gesang flower (Tibetan), Jindalai (Korean), mountain pomegranate, etc. Among all the ornamental flowers and trees, it can be called beautiful flowers and leaves, and it is suitable for ground plants and potted plants, and it is the most widely used. In the natural distribution of azaleas in the world, there are many kinds and huge quantities, none of them can match China, and China is a treasure trove of rhododendron resources in the world!

Nowadays, Jiangxi, Anhui and Guizhou take azalea as the provincial flower, and there are as many as seven or eight cities that are designated as the city flower, which shows people's love for rhododendron. When the azaleas are in full bloom, just when the cuckoo bird is crying, the ancients left many poems and beautiful and moving legends, and there is a custom of taking flowers as a festival. Rhododendron is mostly a shrub or small tree, which has its own living habits and shapes due to different ecological environments.

The smallest plants are only a few centimeters tall and are cushion-shaped and close to the ground. The largest is several feet tall and stands majestically and magnificently.

There are many reasons why azaleas turn black, so there are many possibilities that can cause azalea leaves to turn black, such as: watering the azalea, inappropriate ambient temperature, improper lighting conditions, etc., all of which can cause the azalea leaves to turn black. Unsuitable ambient temperature, improper lighting conditions, etc., can cause the leaves of azaleas to turn black.

In addition to the effects of watering and temperature on azaleas, if not properly maintained, it is possible to cause the leaves of azaleas to turn black. The light conditions of the azalea should be in semi-shade, or there should be scattered light.

That means that there is a problem with the root system, there is a problem with the stem and leaves, that is the problem of the root system, it is best to check the root system, if the root system is wrong, then the plant can not be wanted.

Some time ago, I wrote an article about the most delicate flowers in winter, there are azaleas, there may be some flower friends who will refute these flowers, because their rhododendrons have been propagating for a long time, and there are almost no problems, in fact, rhododendrons that have been bred for many years, and later reproduction is really not prone to problems, but just contacting friends of azaleas, it may not be very good. So today we will take a look at this problem, what is the problem with the black zoom of the rhododendron leaf tip, and how can we solve it?

1. The leaf tips caused by watering are blackened

In fact, many people don't know what the problem is when breeding rhododendrons, and later found that after various inquiries, it turned out that this problem will occur because of watering, and it may be possible to ensure good recovery if you pay more attention to it in the future, but it is recommended that you can not water frequently no matter what you usually do. The flowers of this plant are also multiplying, and they are still relatively drought resistant, so long-term watering is no problem. But once you water too much, there will definitely be problems.

Therefore, when the leaf tip begins to have black scorch, it must be dealt with in time, otherwise it will not survive.

2. The light is too strong

Outdoor propagation of azaleasIf you are careful, you will find that azaleas are planted in the shade and there are not many hours of exposure to the sun in a day. Therefore, it is not recommended to put the rhododendrons propagated at home in a good position directly in the sun, because the strong sunlight in summer will cause problems to the plants, such as rhododendrons will appear black and scorched leaf tips, move it to a cool place in time to breed.

3. The air is too dry

There are many places where azaleas are planted in Qingdao, and its shadow can be seen everywhere in the park. Some flower friends may ask why my rhododendron always grows badly. In fact, it also has a lot to do with humidity, Qingdao is a coastal city, no matter which season the humidity is relatively high, it is very good for the growth of plants.

Therefore, reproduction will also be good, but the indoor humidity should not be large, otherwise it will naturally cause the leaf tip to be black and burnt. It is recommended to spray water around the plant regularly when propagating.

It is very likely that the water is relatively small, and the surrounding temperature is relatively high, at this time, the azaleas should be placed in a place with a suitable temperature, watered regularly, and at the same time to maintain the permeability and drainage of the soil, so that the azaleas will grow better.

Because the azalea lacks fertilizer, it will appear black. How to solve this problem, then the rhododendron should be watered and fertilized in time.

It is possible that you will hand in too much fertilizer and be burned to death, at this time you can dig up the azaleas, change the pot again, and water some water.

Please note the following: (1) Usually rhododendrons will grow vigorously when they live in acidic soils, and if they are in alkaline soils, they will soon die of leaf yellow decay. Rhododendron is seen as an indicator plant for acidic soils.

Humus soil is generally acidic soil, and pine leaf humus is the best, which is an ideal cultivation soil for planting rhododendrons.

2) Watering, rhododendrons are afraid of waterlogging, and are not drought tolerant, too dry or too wet is not good for plant growth. If there is a lack of water during the flowering period, the petals will be soft, the flowers will droop, the color will not be bright, and even the flowers will wither and die. The principle of watering is not to dry or water, watering must be watered thoroughly, and half of the water is strictly prevented.

I don't know where you are (south or north), it's hard to say that you water once a few days.

3) The water quality of watering, long-term use of tap water will aggravate the alkalinity of the potting soil, which is not conducive to the growth of rhododendrons. Therefore, the water must be treated before use. Long-term watering of ferrous sulfate aqueous solution, or 10-15 days in a pot sprinkled with a little ferrous sulfate.

4) Watering, azalea is a flower that does not need a lot of fertilizer, if the fertilizer is applied too much or too thick, it will be detrimental to its growth. It should be fertilized at the right time and in the right amount. That is, "dry fertilizer is applied less, liquid fertilizer is applied thinly."
