Why did the newly bought azaleas lose their leaves? Measures to avoid flowers and leaves of rhododendron

Flower friends who want to cultivate cuckoos, the cuckoos you buy from the flower market are usually cultivated in greenhouses, and if you bring them home from the flower market, without the greenhouse environment, it is easy to cause the cuckoos to appear yellow leaves and wither. At this time, some measures need to be taken! The specific practices are as follows.

First of all, we should first find out the root system of rhododendron.

The cuckoo, which grew up in the greenhouse, has a very good growth environment and proper maintenance, which leads to the loss of leaves after the lack of these conditions. In fact, in comparison, that is to say, this is like a spoiled child, suddenly sent to live in poor areas, it will be difficult for him to adapt.

II. Measures

(1) the azaleas that have just been bought should be given sufficient air humidity as far as possible to keep its basin soil moist, and should not be placed directly in the outdoor cold air, and friends who maintain them at home can put them on the sunny south balcony.

(2) he should be given enough light in winter and early spring, keeping the temperature no less than 12 degrees Celsius, preferably between 18 and 22 degrees Celsius.

(3) once the azaleas are cultivated in one place, do not transfer the position casually, lest the azaleas will not adapt because of the drastic change of temperature. If the young leaves of the rhododendron wither, it means that there is a lack of water. If the potted soil is not dry, water should be sprayed on the potted plant and the surrounding environment to increase its environmental humidity.

(4) if you find the azaleas bought by yourself, and the root system is injured, you should nourish its roots first. If it still can not recover, then the buds of azaleas should be removed, leaving only a few buds, which can reduce the consumption of nutrients absorbed by azaleas, and then give it normal maintenance operation.

(5) in autumn, we should give priority to spraying water, supplemented by watering. At this time, the climate has gradually begun to drop, and the temperature has also become lower, so the potted soil of azaleas is not so easy to dry through. Once it is watered too much, but it is prone to the phenomenon of rotting roots.

(6) pruning the azaleas. If the azaleas have yellow leaves or diseased branches, it is also easy to cause them to lose their leaves. At this time, these branches and leaves should be cut off in time, so as not to cause excessive consumption of nutrients.

The editor reminds everyone that if there is a phenomenon of falling leaves in the azaleas you bought, you should pay attention at this time. To see this phenomenon, you can first refer to several situations introduced by the editor above, and then find corresponding methods to solve this problem in time.

Why does the rhododendron lose its leaves? the solution to the loss of leaves in rhododendron.

The main reasons for the loss of rhododendron leaves are improper water and fertilizer, alkali soil and water, etiolation of element deficiency and poor root absorption. Azalea must be watered in time in the process of planting, but it should not be watered too much, just the right amount. Usually, we should apply some alum fertilizer to the azaleas and give them reasonable light.

Reasons for the loss of rhododendron leaves 1. Improper water and fertilizer

It is mainly caused by mismanagement. The root system of rhododendron is delicate, afraid of early, waterlogging, and fat. If the water is insufficient or missed, it will cause the leaves to wilt and droop, when the leaf tip is scorched and scorched, and the leaves and buds fall off. If the soil is watered too much and the soil is too wet for a long time, the root system will suffocate and rot, which can easily lead to the yellowing and shedding of the old leaves in the lower layer, and the serious leaves will almost be stripped off. If the fertilizer is too thick or the raw fertilizer is not mature, the plant will be damaged by fertilizer, and the leaves of the lighter ones will turn yellow and the leaf tips will be scorched. The branches dried up, a large number of leaves fell, and the heavy ones died of the whole plant. Once fertilizer damage occurs, it is necessary to increase watering to make fertilizer flow out of the drain hole and, if necessary, to turn over the basin to change soil.

2. Alkali in soil and water.

Rhododendron likes slightly acidic loose soil. if the basin soil is alkaline or irrigates alkaline water for a long time, it will inevitably affect the root absorption of nitrogen, iron and other elements, resulting in plant iron deficiency and leaf yellowing. In order to prevent chlorosis caused by iron deficiency, go to the chemical store to buy a small packet of ferrous sulfate (commonly known as black alum). Soak it in a water tank and water it with 0.2% black alum every day, so that the leaves will not turn yellow or even wither and fall off. In addition, a few drops of edible rice vinegar can also be added to the water for watering flowers, which can also increase the acidity of the soil.

3. Etiolation of element deficiency

When the plant is deficient in iron or magnesium, it will cause chlorosis between the veins of rhododendron leaves, but the veins of rhododendron leaves are still green; when sulfur deficiency, it will also lead to yellowing of young leaves, serious whitening and transmission to old leaves, which elements can be determined by leaf analysis and soil analysis, and then supplement the corresponding elements. Usually, iron deficiency is the most common, as long as the leaves turn yellow, it is considered to be caused by iron deficiency, but sometimes this is not the case.

4. Root malabsorption.

Under the same environmental conditions, all kinds of rhododendrons are maintained and managed by the same person, and some varieties are easily yellowed, such as "Xintiandi", "Dahong double sets" and so on, which is related to the absorption function and environmental adaptability of the plant itself. Especially when the temperature is high in summer, yellowing is especially obvious, and most of them improve or return to green after cool autumn. Although the symptoms are similar to those of iron deficiency, iron supplementation has no effect on it. Root protection and root protection measures should be taken to deal with this kind of yellowing phenomenon. It is necessary to maintain a high temperature when overwintering, shade when it is hot in summer, spray water to cool the surrounding environment, maintain good ventilation, and promote the healthy growth and development of plant roots.

5. Temperature / sunshine

The temperature and humidity are not suitable, the temperature is either too high or too low, and the humidity is either dry or humid. Such an environment is not suitable for rhododendron growth, resulting in the loss of leaves will often occur. Lack of light for a long time. If the azaleas are placed in the dark corner for a long time, it is inevitable that the fallen leaves will wither. As the saying goes, the growth of all things need sunlight, if there is no light, then naturally can not survive.

The solution to the loss of leaves of rhododendron

1. Watering the right amount: Azalea must be watered in time in the planting process because its roots are not resistant to drought, but we should also be careful not to water too much, just the right amount. Be sure to pay attention to "watering thoroughly", usually to spray water to the leaf surface and its surroundings to improve the humidity of the environment.

2. Keep the acid soil: usually you should apply some alum fertilizer to the azaleas, or add a little ferrous sulfate to the water to maintain the soil acidity value of planting azaleas.

3. Proper amount of fertilization: add an appropriate amount of slow-release fertilizer to the rhododendron pot soil (organic film is coated with fertilizer, and the fertilizer is slowly released to supply plant nutrition through the infiltration of the film), which is safe, clean, long-lasting, colorful and Yemao. This fertilizer is often used in horticultural production, which is both convenient and clean, and the planted rhododendron leaves are luxuriant.

4. Reasonable sunshine: if you give the azaleas reasonable light, you can put the azaleas in a place with plenty of light, and then move to a semi-shady place after the weather turns warm in spring. It is best to cultivate azaleas in sunny and sheltered places sooner or later.
