The azalea leaves have fallen off, what should I do?

Because the rhododendron is a flower in the south, it also has high requirements for humidity, we must give it a large air humidity, we have to artificially create an air humidity for it, you can put a brick at the bottom of the pot, put it in a container, pour water into the container so that the bottom of the pot does not touch the water, so that it can have a continuous evaporation of air humidity. When the humidity is high, it will grow normally, and there will be no leaf litter.

Another rhododendron must maintain good ventilation, ventilation will not appear rotten leaves and fallen leaves, azalea likes large air humidity like moist soil, but it does not mean that it likes to water it all the time, let it grow in a silted environment so that its root system will rot. The ventilation effect of the winter maintenance rhododendron is very poor, and it will not dry for a long time after watering. If the soil has been silting, it will lead to the problem of root damage, and the root system will inevitably fall off in a large area, and the flower buds will also fall off in a large area.

Another is the azaleas we bought, which are generally made of very permeable soil. For example, the pine needle soil is planted directly, so that after watering, the water can flow directly from the bottom of the pot, and after flowing down, the water left in the potting soil is very small, and the indoor temperature is very high in our winter in the family, and some even squat directly on the ground with floor heating.

You don't know that the potting soil is completely dry, you don't water it, it can't get water, its leaves will roll inward, and then fall off in a large area, generally this situation is the most common, if your leaves have dry edges, the potting soil has been completely dry, which proves that it lacks water and quickly watered it. Raising azaleas is very harsh on moisture, whether it is moisture or humidity, so you should often look at the potting soil to see if the potting soil is dry If the potting soil is deducted two centimeters, there is no water, quickly water it, do not wait until you try the pot is very light and then water it, which will inevitably hurt the roots and cause leaf fall.

If you want to raise azaleas, the first one to increase the humidity of the air and the other not to see bright light. Especially in winter, give it some scattered light, let it bloom completely, and then gradually increase the light for it, and create a better ventilated environment for it as much as possible. If you don't fertilize it during flowering, fertilizing it will cause it to sprout, and growing sprouts will cause the buds to fall off.

After its flowers are completely bloomed, cut off the residual flowers and then fertilize it, as long as you maintain the azaleas according to these points, you can raise it very well all year round.

This means that the environment may be too hot or too cold, causing all the leaves of the azalea to fall off, so you must pay attention to the temperature of the environment, but also pay attention to air circulation, and have a certain amount of regular watering.

The azalea leaves have fallen out, so you should water it frequently, then fertilize the azalea regularly, and plant the azalea in a sunny place.

If the leaves of the planted azaleas have fallen off, don't panic. It must be watered on time every day, fertilized frequently, and given plenty of sunlight.

This is because of the environment, the growth environment of the rhododendron needs a more humid environment, you can add more water to it appropriately.

The first is to consider the lack of water and water in time. The second is to consider whether there are insects and kill them in time. The third is to consider whether the temperature is too low or too high to adjust in time. Fourth, there are environmental factors. The fifth is to consider whether the soil is nutrient-free and replace it in time

Rhododendron leaves are losing their leaves for these reasons.

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 put a few drops of edible vinegar on the watering to relieve the pH value.

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.

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.

There are actually many reasons for the rhododendron to drop the leaves, but the subject's rhododendron has been dropping its leaves in the summer, which may be caused by the hot weather, which shows that the rhododendron must be selected in the summer, otherwise the leaves will be very unsightly, it is recommended to move to a place with less light and ventilation in time, so as to slowly alleviate the phenomenon of falling leaves.

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.

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.

The meaning of the rhododendron

1. Prosperity

Rhododendron is an auspicious and beautiful flower in our country, and it is often used to decorate public places and express the meaning of praising the prosperity of the motherland during festivals and celebrations. And there is a cloud in "Grass and Flower Spectrum": "If the red mountain is born on the top of the mountain, its year is rich and stable, and people compete to pick it."

2. Friendship lasts forever
