How to yellow the leaves of azaleas? the solution to the loss of leaves of rhododendrons

Azaleas are neutral flowers and plant a pot at home, which adds a lot of atmosphere to the home decoration and makes people look very comfortable, but some friends find their azaleas leaves more and more yellow when they are planted, which is very distressing. The following editor will introduce the way to solve this problem.

What if the rhododendron leaves turn yellow?

1. Improper water and fertilizer

Azaleas, such as underwatering or overwatering, over-fertilizing or applying unripe raw fertilizer, will cause leaves yellowing and serious death of the whole plant. Water and fertilizer should be appropriate. When there is too much water and fertilizer, you can turn the basin and change the soil.

2. Alkali in soil and water.

If the basin soil is alkaline or irrigated with alkaline water for a long time, it will affect the absorption of iron by plants, resulting in iron deficiency and yellowing of leaves. You can buy some ferrous sulfate and water the cuckoo with 0.2% solution every day, or you can add a few drops of edible vinegar to the water to increase the acidity of the soil.

3. Malabsorption of root system

When the summer temperature is high, the yellowing is particularly obvious, and it will improve or return to green after the autumn is cool. For this kind of yellowing phenomenon, measures should be taken to protect and protect the roots. It is necessary to maintain a high temperature when overwintering, shade in summer, spray water to cool down, maintain good ventilation, and promote the healthy growth and development of plant roots.

The solution to the loss of leaves of rhododendron

1, to maintain the humidity of the air and basin soil, proper shading, need air circulation, and there is no rush to change soil and fertilize. Give sufficient light in winter, under the south window as far as possible in indoor maintenance, the ambient temperature can not be lower than 5 degrees. Do not change places at will, so as to avoid drastic changes in temperature. Don't put it in a place where the air is dirtier.

2. The acid soil with good ventilation and rich humus must be used in the culture soil, and the pH value between 5.5 and 6.5 is the most suitable. Usually some alum fertilizer should be properly applied, or a little ferrous sulfate should be added to the water. If alkaline soil is used, it will cause leaf yellowing and shedding.

3. When changing the basin, add an appropriate amount of slow-release fertilizer to the basin soil (the fertilizer is coated with organic film, 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.

4. Cuckoos should be cultivated in sunny and sheltered places sooner or later.

How to raise azaleas

1. Soil: the general cultivation methods of plants and flowers are inseparable from the good soil environment, and the soil environment is more important for the cultivation methods of azaleas.

2. Watering: watering is a very important work. For the cultivation method of rhododendron, the watering skill is very important. When watering, it is necessary to water properly, and the best watering time is in the morning and evening. This is good for azaleas to absorb water.

3. Fertilization: azaleas are very atmospheric flowers and do not need too much fertilizer to grow, so be careful not to apply too much fertilizer. Too much fertilization will make it difficult for azaleas to absorb and die. Proper fertilization can make azaleas grow well and bloom beautifully.

4. Sunshine: another very important and indispensable thing in the planting method is the absorption of sunlight. For plants and flowers, it is necessary to promote photosynthesis. Therefore, the growth of azaleas is also inseparable from the sun, but can not be exposed to the sun all day, suitable sunshine can make azaleas bloom more beautiful and moving.

Matters needing attention in planting rhododendron

1. The acid soil with good ventilation and rich humus must be used in the culture soil, and the pH value between 5.5 and 6.5 is the most suitable. Usually some alum fertilizer should be properly applied, or a little ferrous sulfate should be added to the water. If alkaline soil is used, it will cause leaf yellowing and shedding.

2. Cuckoos do not like big fertilizer, once raw fertilizer and thick fertilizer are used, fertilizer damage will occur.

3. When changing the basin, add an appropriate amount of slow-release fertilizer to the basin soil (the fertilizer is coated with organic film, 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. The root system of cuckoo is slender, such as poor permeability of basin soil or excessive watering for a long time, coupled with poor ventilation, the system is damaged, resulting in wilting and falling leaves.

4. when watering the cuckoo, we must pay attention to "watering it thoroughly" and usually spray water on the leaf surface and its surroundings to improve the humidity of the environment.

5. Cuckoos like light but fear the scorching sun, like ventilation but fear strong winds. Placing in the hot sun in summer and in the tuyere in spring (especially in early spring) and autumn will lead to a large number of fallen leaves. Attention should be paid to the cultivation of cuckoos in sunny and sheltered places sooner or later. Cuckoo's soil should be permeable and acidic.

What is provided above are some tips and matters needing attention for planting azaleas. You can operate according to the above method, but there may be some other situations in the process. So we should combine the above theory with the actual situation to find out the most suitable method for planting.
