Causes and solutions for rhododendrons to lose their leaves

Rhododendron leaves are losing their leaves for these reasons.

Rhododendron flowering is very beautiful, there are several types, the flower color is different, there are spring cuckoos, summer cuckoos, etc., the flowering time is not the same, but the growth habits of azaleas are about the same, when we raise azaleas potted plants, some friends say that although the azaleas are very beautiful, it is really a bit contradictory, especially want to raise a pot at home, but I feel that I can't raise it well, for example, sometimes I will encounter such a situation, that is, the leaves on the branches are dry and tip, or they fall off when they touch it, If you find that the leaves are not green enough, the tips of the leaves are black, or the edges are scorched, etc., then you must pay attention to these points in maintenance

First, don't water too much

Too little or too much watering is not good, especially in summer, when the temperature is relatively high, when the air humidity is small, we must water the azalea in time before the potting soil becomes dry, the potting soil can not be short of water for a long time, the lack of water will cause the leaves to dry up and wilt, and even the yellow leaves will fall, and at the same time increase a certain air humidity.

However, if the pot soil has been wet, or the rain has been too long, has been so that there is water in the pot, which will also lead to large water, stuffy roots, at this time, if you don't want to trouble, you can remove the pot, the soil ball is directly placed in a shaded and well-ventilated place, the water is dissipated, be sure not to bask in the sun, be sure to ventilate, control the return wheel to water, reduce the amount of watering. Do not water the potting soil if it is not dry.

Second, you need to pay attention to the high temperature in summer

Because of the rhododendron in summer, it is best not to expose it to the sun, and to shade it if you can, put it under some other trees to take a shade, or put it in a place without direct sunlight, so that the leaves will be green.

If the temperature is too high, watering is not timely, the temperature is too high, placed in a place that is not ventilated, it will also be easy to fall off leaves, in summer, be sure to astigmatism, keep the potting soil slightly moist, maintain good ventilation on the line, so pay attention not to bask in the sun in summer, to put in the shade, astigmatism, ventilation of the place to maintain, the leaves will naturally be green.

Third, fertilization must be cautious

Hypertrophy can also lead to black leaves, yellow leaves and so on. Especially in the summer when the temperature is high and the temperature reaches 30 degrees, do not apply fertilizer anymore. In order to avoid fattening and causing the leaves to turn yellow.

If the potting soil is not replaced for a long time, it is not possible to do it for a long time, the soil becomes barren, and the soil in the pot can be seen with the naked eye to become lighter and more compact, so that the soil is not conducive to the growth of rhododendrons, we can loosen the potting soil in the autumn, add some fertile and acidic humus, about three or four centimeters thick, in the pot. What's going on with rhododendrons dropping their leaves? Find 3 reasons, the leaf color is in a good green state, and the leaky letter will bloom more next time!

<>1. Temperature: To treat the rhododendrons that have lost their leaves, the ambient temperature needs to be controlled at about 20 degrees to avoid poor growth of the reeds.

2. Watering: Rhododendron is not resistant to waterlogging, and it is necessary to wait for the surface of the soil to turn white before watering.

3. Light: Move the azalea to the scattered light to avoid it being directly exposed to strong light.

4. Soil: Prepare slightly acidic fertile soil for rhododendrons. ”

Rhododendron is also known as Yingshan red, is a flower with high ornamental value, there are many flower friends like to breed plants at home, rhododendron breeding is more troublesome, we need to take care of it carefully, otherwise there will be all kinds of problems, the following by the fortune tree home for you to explain what to do with the azalea leaves.

Rhododendron sheds leaves causes.

The soil is not comfortable

Rhododendron cultivation has very high requirements for the soil, rhododendrons like loose and fertile acidic soil, pH value between 5 6 is the most suitable, and when we breed, long-term soil change may lead to soil alkalization, which will have a serious impact on the growth of rhododendrons.

Treatment: What to do if you find that the azalea has lost its leaves, if it is because the soil is not suitable, it is recommended to change the soil directly. If the soil in the north contains a lot of alkali salts, ferrous sulfate can be used for neutralization and reuse.

Improper watering

Breeding rhododendrons have very high requirements for watering, we also have to master watering skills, watering can not be too much, it is easy to cause the rot of its roots, resulting in leaf fall, and long-term lack of water will also cause its leaves to dry up and fall.

Treatment: If the leaves fall due to excessive watering, we need to move the roses to a place with better ventilation conditions for maintenance, and properly loosen the soil to allow the water to evaporate faster. When we are short of water, we need to hydrate it appropriately.

Improper lighting

Light is also very important for rhododendrons, which need to be given a reasonable amount of light, which needs to be given enough scattered light under normal circumstances, and also needs to avoid damage to the leaves caused by strong light, which can dry up and fall off.

Treatment: For light, it should be placed in a sunny place under normal conditions for maintenance, and in summer, it needs to be shaded and sprayed with an appropriate amount of water around.

Improper fertilization

Rhododendron demand for fertilizer is not high, so it is necessary to pay attention to the fertilization concentration and amount of fertilization, the concentration is too high or the fertilizer is too blind, which will cause its leaves to burn off and fall off.

Treatment: When breeding rhododendrons, because of too much fertilization causes their leaves to fall, we need to immediately stop fertilizing and increase its watering, so that the excess fertilizer flows out of the basin with the water, and it needs to be replaced when necessary.

The above content is a detailed introduction to what to do when rhododendrons lose their leaves, and through the above analysis, we can have a better understanding of rhododendron farming.

Through our introduction, I believe you have a deeper understanding of what to do when azaleas drop their leaves, and find the reason for the correct treatment.

1. Curing temperature; Rhododendron has strict requirements for maintenance temperature, especially in autumn and winter, when the weather is cold, it is necessary to pay attention to low temperature frost damage. Rhododendron should generally be kept at a maintenance temperature of more than 10 degrees in autumn and winter, otherwise it will cause defoliation due to low temperature. In winter, because the weather is cold, do not change pots and apply a lot of fertilizer at this time, so that the plant absorption rate is slow, and the natural growth will not be very good.

Rhododendron in autumn and winter try to place it in a sunny place at home, so that it receives warm light, and care for azaleas should also pay attention not to move the position of the pot frequently, so as to ensure the growth of azaleas.

2. Fertilization intensity; Rhododendron is a fertilizer-loving plant, and its fertilization process is divided into two steps, that is, base fertilizer and top dressing. Because the root system of azaleas is relatively fragile, try not to choose too thick fertilizer when applying base fertilizer at the beginning, so as not to overnutrient and burn the flower roots. Top dressing is a very technical thing, and if it is not done well, then the flowers will have yellow leaves and fallen flowers.

Rhododendron should also ensure that thin fertilizer is applied frequently, so as to ensure the growth of azaleas in autumn and winter.

3. Selection of soil substrate; Rhododendron likes to grow in acidic and well-drained and loose soil, although we may prepare no problem with the soil substrate at the beginning, but after a long period of curing, the acidity in the soil will decrease, at this time we need to prepare some acidic solutions regularly to water it to improve the acidity of the soil. If the soil substrate is fine, the natural rhododendrons will not appear bad during the growth process.

4. The change of seasons; People will have some small problems when the seasons change, and azaleas are no exception. Whether it is the transition from summer to autumn or the upcoming transition from autumn to winter, the azalea will automatically reduce the moisture in the branches and leaves because the weather is slowly getting colder, and finally it will enter a dormant state in winter.

5. Pruning of branches; Any plant will grow and flourish after pruning its branches. Rhododendron is a flowering plant, so it is necessary to prune the discarded branches and long branches in the pot before the flowering period begins, so as to promote the differentiation of new shoots, and the number and speed of flowering will naturally increase.
