Why do azaleas drop their leaves, and why do azaleas drop their leaves

Rhododendron leaves are losing their leaves for these reasons.

There are many varieties of rhododendrons that have been waiting for a long time, and the reasons for the loss of leaves under different varieties are also different, and the common reasons may include: 1Not enough water:

Rhododendron is a sensitive plant and often loses its leaves if it is not properly watered or insufficient; 2.The growth environment is not suitable: too strong light, too low humidity, and too much soil nutrients will cause rhododendrons to lose their leaves; 3.

Pests and diseases: lack of nutrients or poor growth environment will cause rhododendrons to lose their leaves, in addition, moss mite invasion will seriously damage the beautiful crown of rhododendrons, and the shrunken leaf veins are also a manifestation of bryomite disease blind rent; 4.Hereditary factors:

Different rhododendron varieties have different resistance resistance, and some varieties are very prone to leaf loss. In summary, the leaves of rhododendrons may be caused by insufficient water mills, improper growth environment, pests and diseases and hereditary factors, and the solution is to replenish water to plants in a timely and sufficient manner, improve environmental nutritional conditions, and find pests in time to control and replace plant species.

1. Replace the potting soil.

Because it prefers to grow in soft, breathable, well-drained acidic loam, but because of the application of alkaline water for a long time, it may cause the loam to become compacted and alkaline, so the root growth will be restricted and suffocated, causing the leaves to fall and die.

You can replace the potting soil inside and replace it with new culture soil to ensure that the pH value is smaller, or add Bika microbial agent to balance the pH value.

2. Increase or decrease light.

It is a semi-negative flower that generally needs shade in spring, summer and autumn, but in winter it needs to be exposed to sunlight, and if there is too little sunlight contact at this time, it will cause leaf loss. In the case of the scorching summer sun, exposure to the scorching sun can also cause this situation.

The right amount of light should be given according to the season, if there is no light, it should be moved outdoors, and if there is too much light, it should be placed in a cool place.

3. Adjust the temperature.

Temperature is critical for maintenance, once the temperature is above 30, or below 3 in winter, the plant will have a bad effect, the whole plant will change, and the leaves will naturally fall.

The position can be adjusted according to the weather conditions, and it is best to keep it at 15-25.

Rhododendron leaves may be due to these reasons.

Hello dear! 1. The soil is too alkaline, and the rhododendron prefers a weakly acidic soil environment. If alkaline soil and water are used for a long time, it will affect the absorption of nitrogen and iron by the roots, resulting in iron deficiency and oxygen deficiency of plants, and the lack of chlorophyll and yellowing and shedding.

The solution is to add a little ferrous sulphate to the pot to acidify the soil. 2. If the fertilization is too concentrated, it will cause fatal damage to the rhododendron, which is manifested as fallen leaves on the surface, but is actually a root injury. The folk proverb says:

Shiragen has strength. The yellow root is sick, and the black root is dying. "The solution is to check the root system, if the root system is yellow, it can be treated as soon as possible, and if it is blackened, it is already terminally ill and difficult.

Remove dry fertilizer, change the soil partially, do not replace it all, and do not wash the roots. Water several times a day, dilute the fertilizer, and place it in a sheltered place from scattered light, keep the environment moist, and slowly recover.

3. Rhododendron usually needs more than 12 hours of light to produce buds. However, the cuckoo has a certain selectivity to light intensity, prefers semi-shade, and is afraid of strong light. Exposure to strong light will cause a large number of leaves to fall in the rhododendron.

and even cause death. The solution is to move the cuckoo to a shady place. 4. Rhododendron with too much water likes moisture, is afraid of drought, and is not waterlogged, such as long-term water accumulation in the pot or long-term drought without watering, often resulting in a large number of fallen leaves.

If the treatment is not timely, only dead branches and leaves will be left soon, and eventually the plant will die. The solution is to change the potting soil to improve the potting soil conditions, promote the slow recovery of the root system, and breed new roots.

It is necessary to respect the habits of the rhododendron and conform to the habits of the rhododendron such as liking weak acidity, avoiding heavy fertilizer, being afraid of drought and flood, being afraid of strong sun, and being moist, so that the rhododendron can grow well.

It may be a lack of nitrogen, you try to change the soil, it may be caused by a lack of nutrients. Also, you can use rice washing water to water the flowers, because rice water contains nutrients. If you have the habit of drinking tea, you can use tea residue to water the flowers, and put the tea leaves on the soil, which is very useful for plants.

Don't worry about the rhododendron losing its leaves, solve these 3 reasons in time, and it will soon come to life with bright colors.

Reason: The sudden change in the growth environment of the newly bought azalea, especially the sudden change in air humidity, can easily make it fall off.

Solution: Put the newly bought azaleas in a relatively cool environment for a while.

Reason: Rhododendron has high requirements for air humidity, the humidity in the trellis is generally 70-80%, and the humidity in the home is generally a little more than 20%. If the air is too dry, the azaleas will reduce water evaporation by shedding their leaves.

Solution: Increase the humidity of the air around the azalea, you can use a spray, or you can put a pot of water around it.

Cause: Too much watering can cause the rhododendron's root system to rot, further aggravating its leaf loss.

Solution: Reduce watering and wait for the soil to dry before watering, <>

The reasons for the loss of leaves in rhododendrons are: dry soil, poor ventilation, and strong direct light.

1. Soil aridity

Rhododendron has individual leaves yellow, falling, flower buds become dry, at this time you can weigh the weight of the potting soil, feel particularly light, most of them are not watered for a long time, the soil is too dry caused, the root system can not absorb enough water, will hinder normal growth.

2. Poor ventilation

Rhododendron likes to grow in a well-ventilated environment, if the maintenance environment is closed and not ventilated, the rhododendron will turn yellow and wilt, the phenomenon of falling, and in severe cases, the plant will be infected with diseases and rot roots.

3. Direct sunlight

Rhododendron likes sunlight, but long-term exposure to strong light will cause a large number of leaves to fall, especially in the ground, can not move, the most prone to yellow leaves, leaf dropping, at this time to pull a layer of shade net.

Rhododendron Simsii Planch）：

Also known as mountain red, mountain pomegranate, is evergreen or ordinary green shrub. According to legend, there were cuckoo birds in ancient times, crying day and night and coughing up blood, dyeing red flowers all over the mountain, hence the name. Rhododendron generally blooms in spring, with 2-6 flowers per cluster, and the corolla is funnel-shaped, with red, light red, apricot red, snow blue, white, etc., and the flower color is lush and gorgeous.

It grows under mountain shrubs or pine forests at an altitude of 500-1200 (-2500) meters, and is a typical acidic soil indicator plant in south-central and southwestern China.

The whole plant of this species is used for medicinal purposes: there are diseases such as qi and blood activation, replenishment of deficiency, internal injury and cough, kidney deficiency and deafness, irregular menstruation, rheumatism and so on. Because of the bright red color of the corolla, it is a famous flower plant with high ornamental value and is cultivated in various parks around the world.

Jiangxi, Anhui and Guizhou in China regard azaleas as the provincial flower, and there are as many as seven or eight cities designated as the city flower. In May 1985, rhododendron was rated as one of the top ten famous flowers in China.

The record of rhododendrons was first seen in the Han Dynasty's "Shennong's Classic of Materia Medica", in which the "sheep heel" was listed as a poisonous plant. The history of rhododendron cultivation has a history of at least 1,000 years, and in the Tang Dynasty, ornamental azaleas appeared, at this time the azaleas have been transplanted into the garden for cultivation, and the famous Tang Dynasty poet Bai Juyi (772-846) had a soft spot for azaleas.

Bai Juyi not only wrote many poems praising rhododendrons, but also transplanted and cultivated them himself, and the first transplantation did not survive, and he wrote "Fighting for the deep roots of the stone, and moving to others for no reason"; In 820, it was finally transplanted to life, and the poem said: "Today's flowers in Zhongzhou Zhouli, last year's tree on the top of Lushan Mountain, has been pityfully damaged and newly planted, and the flowers are still blooming." ”

According to records, in the first year of Tang Zhenguan (785), people had collected rhododendrons for cultivation, the most famous being the azaleas cultivated in Zhenjiang Helin Temple.

In the Song Dynasty, there was a new development in the cultivation of azaleas, and the poet Wang Shipeng once transplanted azaleas in the courtyard: "The creation of my small garden, this flower is better than the gold belt." "Southern Song Dynasty "Xianchun Lin'an Zhi":

Rhododendron, there is this flower in the Bodhi Temple at the Qiantang Gate, it is very prosperous, Su Dongpo has the rhododendron poem of Nanyi Hall, the foundation of the hall is preserved, and there are many mountains where this flower is located. It shows that azaleas are common in Hangzhou courtyards.
