What about the latest azalea leaves?

The characteristic of azaleas is that they like acidic soil, like moisture and warmth, and are afraid of thick fertilizer, sun exposure, drought and flood. Abnormal fallen leaves often occur in poor management. Here are the reasons and solutions for cuckoo falling leaves.

What if the rhododendron loses its leaves?

1. Defoliation due to environmental discomfort

Most of the cuckoos sold on the market are cultivated in greenhouses and cannot adapt to the natural environment of the family after being bought back, often with fallen leaves or even death. Rhododendrons cultivated in different places have the same problem.

[solution] the newly purchased cuckoos should try to maintain air humidity, proper shade, keep the basin soil moist, need ventilation but can not blow directly in the cold wind, and are in no hurry to change soil and fertilize, so as to make it safely through the adaptation period as far as possible. Winter should be given full light, in indoor maintenance as far as possible under the south window, 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. Unsuitable defoliation in basin soil.

[solution] the acid soil with good ventilation and rich humus must be used to cultivate the soil, and the pH value of 5.5 to 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. fat and harmful deciduous leaves

Cuckoos do not like big fat, and the most common deviation in planting cuckoos in families is not lack of fertilizer, but excessive fertilization. Once the use of raw fertilizer, thick fertilizer will appear scorched leaves are caused by fallen leaves. The so-called fat damage.

[solution] when changing the basin, add an appropriate amount of slow-release fertilizer to the basin 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. Once the fertilizer damage is found in the family planting, the fertilizer should be stopped immediately, and the fertilizer in the soil should be irrigated and moved to the ventilated place for maintenance after watering. Some of them need to be washed twice, and the normal growth can be restored gradually after about half a year of maintenance.

4. Waterlogging defoliation

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, root system damage, rot, resulting in fallen leaves.

5. Dry and harmful deciduous leaves

If you are not careful, forget to water, or do not water thoroughly for a long time, there will also be fallen leaves. 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.

6. Daylight, strong wind

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.

[solution] attention should be paid to the cultivation of cuckoos in sunny and sheltered places sooner or later.

7. Physiological deciduous leaves

The flowering is too dense, and the old leaves will be removed when the nutrition is not supplied in time or when drawing new leaves, which can be solved by changing soil and fertilizing normally. Domestic cuckoos usually blossom and sprout new leaves from April to June, and the old leaves will fall off. Pruning and reshaping after flowering, cutting off dense branches, cross branches, weak branches, drooping branches, overgrown branches and disease and insect branches, not only help ventilation and light, promote strong branches, but also reduce fallen leaves.
