"Yingshanhong" what if the leaves of azaleas are dry? What are the solutions? Can it blossom in winter?

Rhododendron, one of the top ten famous flowers in China, has always been loved by everyone. According to the relevant records, the cultivation history of rhododendron has a history of at least more than a thousand years, which was first described in the Han Dynasty. So, what if the rhododendron leaves are dry? What are the solutions? Can azaleas blossom in winter? How to maintain it?

First, what if the rhododendron leaves are dry? What are the solutions?

1. Improper watering

Azaleas have a particularly high demand for water, and excess or lack will cause the leaves to turn black. Especially in summer, the weather is hot, water evaporates quickly, not watering in time will lead to dry soil, lack of moisture in plants, and leaves turn yellow and black. However, too much watering will make the basin stagnant, and the water that cannot be discharged smoothly will accelerate the decay and blackening of the leaves.

Solution: when the leaves have blackened, we should dispose of the necrotic parts in time. At ordinary times, we should observe the state of the soil frequently and strictly control the amount of water. Judge whether watering is needed by pressing the soil. When pressing, water exudates means that there is too much watering. Otherwise, if it is dry, it needs to replenish water.

2. Excessive fertilization

Most potted flowers do not need to be fertilized, but only need to be fertilized during the annual pot change. Azaleas are not tolerant to fertilizer, and many people apply too much fertilizer in pursuit of the quality of flowering, which will lead to excessive fertilizer concentration in the soil and burn out the roots, thus eroding the whole rhododendron plant.

Solution: when we apply fertilizer, we should follow the principle of "applying thin fertilizer frequently". The concentration of fertilizer should not be too high. And you only need to use a small amount of dilute liquid fertilizer before flowering and topdressing after flowering to ensure adequate nutrients.

3. Air drying

Azaleas are suitable for growing in a humid environment, in addition to frequently watering to keep the soil moist, the humidity of the air is also particularly important. If the air is too dry and there is no external water supply, the leaves will turn black and yellow.

Solution: the moisture and humidity of the environment around azaleas need to be kept at 60%-80%. We can put a basin of water next to the azaleas, spray some water mist around it, or put it in a place with high relative humidity to increase the humidity of the air. As long as the water balance, the leaves will not blacken and die.

4. The light is too strong

Azaleas like semi-shade and astigmatism, the summer light is too strong, if the azaleas are placed directly in the sun, it is easy to sunburn the leaves. However, it should not be placed directly in a hidden place to hinder photosynthesis, otherwise the leaves will blacken and fall off.

Solution: we should adjust the placement of azaleas in time and put them in a ventilated place to avoid exposure. At the same time, it is necessary to ensure that there is enough light so that the leaves can absorb sunlight and grow better.

5. Disease pollution

When azaleas are infected with brown spot or black spot, and there are small black spots on their leaves, many flower friends will ask what to do if the azaleas leaves turn black. In fact, this is caused by the environment is too wet or dark, these black spots will eventually spread to the entire leaf, leading to withering and falling off.

Solution: in this case, treat the diseased leaves before spraying the potion, then spray 0.4 Bordeaux, 0.5 degree stone sulfur mixture or chlorothalonil, while mixing flour to increase the adhesion of the drug. In peacetime maintenance, we should also pay attention to ventilation and apply organic phosphorus and potassium fertilizer to increase disease resistance. Usually maintenance also needs to create a good growth environment for azaleas, pay attention to ventilation.

6. Root necrosis

The blackening and death of rhododendron leaves is mostly caused by root necrosis. once there is a root problem, it will endanger the whole soil environment and affect the whole rhododendron plant. When the root system can not absorb nutrients normally, the leaves will be malnourished and blackened.

Solution: when we find the signal that the leaves are black, we should pay attention to the treatment from the root and prescribe the right medicine to the case. The problem of blackening of leaves can be effectively solved by watering azaleas and spraying leaves with methyl topiramate or mancozeb in the ratio of 1: 1000, spraying about three times a week.

Can azaleas blossom in winter? How to maintain it?

1. The rhododendron that blossoms in winter is the western rhododendron. This kind of rhododendron grows more in greenhouses and greenhouses. Its florescence is artificially controlled. It usually blooms before the Spring Festival and ends in April next year.

2. The most suitable environment for rhododendron is ventilated, moist, semi-shady and warm. So people who want azaleas to bloom in winter need to be conserved according to their different environment. For plants growing in the south, azaleas can adapt to outdoor temperatures and spend the winter outdoors. As the temperature in the north is too cold, azaleas must be placed indoors to blossom around winter and can bloom two or three times a year.

3. Loose and fertile loess is required, and it is even better if it is acidic loess. Growers can plant azaleas in the mud basin, because the mud basin is more breathable, which is conducive to the growth and development of roots. Do not use human dung for fertilization. Flower fertilizer can be added to the pot once or twice a month. Keep in mind that the amount of fertilizer should be strictly controlled, knowing that if the fertilizer is too heavy, the plants will burn to death.

4. The most suitable temperature for azaleas to live indoors is 10 to 25 degrees. Because azaleas love a semi-shady environment, they should not be exposed to the sun excessively in summer or too low in winter.
