What is the cause of the yellow leaves of the hibiscus, and what is the reason for the yellowing of

In the process of daily maintenance, the leaves of hibiscus will turn yellow if they are not properly maintained. There are many reasons why the leaves of hibiscus turn yellow, and if you find yellow leaves, you need to treat them in time, so what should you do if the leaves of hibiscus turn yellow? Let's take a look!

The primary cause of yellowing of hibiscus leaves is moisture. Because most hibiscus grows with weak roots, it is easy to lack water and dry up due to excessive dryness of the roots. Therefore, the soil in the pot needs to be added to it immediately as soon as it dries, and the rainy season in the south of the Yangtze River is the high incidence period of yellow leaves in summer.

The potted plants should be moved to a ventilated place with scattered light to increase the evaporation of water, especially the old seedlings that have grown for more than two years, which are more likely to dry out due to lack of water, so we must develop a good habit of watering.

Lack of light is also an important reason for the yellowing of hibiscus leaves. Hibiscus loves light, so in spring and autumn, it is necessary to move the hibiscus to a ventilated and light-permeable place, direct sunlight will increase its growth rate, the stronger the light, the faster it grows. In summer, the high temperature is hot, and it is necessary to transplant the hibiscus under the indoor balcony, do not directly receive sunlight, ensure sufficient scattered light, and replenish water in time; In winter, the hibiscus requires less light during the dormant period, so it is enough to keep the indoor temperature suitable.

Hibiscus blooms most vigorously in spring, and needs to be pruned in time after flowering, and a quarter of the branches can be cut appropriately. After pruning, add nitrogen fertilizer to the hibiscus, prune the branches to an appropriate extent, change to apply liquid fertilizer containing phosphorus and potassium, and apply thin fertilizer frequently to ensure that the growth of the hibiscus is in good condition and prevent the leaves from yellowing.

Hibiscus flowers yellow leaves, flower buds, is it lack of light, lack of water, rotten roots, or lack of fertilizer?

The reasons for the yellowing of the leaves of the hibiscus are:

1. Improper watering.

Hibiscus is a plant that likes a warm and humid environment, but is afraid of stagnant water, if it is watered too much during the maintenance process, the soil will be moist and not breathable, resulting in inhibition of root respiration, so that the rhizome will be hypoxic and wilted, and excessive water will make the new leaves of hibiscus flowers become light yellow, and the old leaves will be yellow and fall off.

2. The light is too strong.

Hibiscus flowers can grow in full light and can tolerate shade, but in the summer high temperature and strong light season, if it is directly exposed to the sun without any shading measures, the leaves will be burned, resulting in the phenomenon of yellowing of leaves.

3. Infected with pests and diseases.

The yellowing of hibiscus leaves may also be caused by pests and diseases, some pests and diseases will leave large black spots on the back of the leaves, and in severe cases, it will cause the leaves to turn yellow, so the diseased leaves should be cut off in time and sprayed with carbendazim solution.

4. Improper fertilization.

Although hibiscus flowers like fertilizer, but can not be fertilized too thick or too often, too thick fertilization will cause root damage, and too frequent fertilization will cause fertilizer damage, both will inhibit root activities, resulting in yellowing of leaves, is not conducive to the healthy growth of hibiscus.

Hello dear. The yellow leaves of hibiscus increase watering, the environment is ventilated, proper light, and fertilization is increased. 1, hibiscus root system is weak, lack of water is very obvious, will directly occur yellow leaf phenomenon, usually after the potting soil is dry, should be watered immediately, and to water thoroughly, the growing season needs a lot of water, generally every day in the morning and evening grinding pure watering 1 time, if the weather temperature is humid, you can appropriately reduce watering, to avoid excessive water accumulation, rotten roots.

2, small hibiscus branches and leaves flourish, the distance between the leaves is small, if the environmental ventilation effect is not good, the water between the branches and leaves can not evaporate normally, long-term maintenance of high humidity, will also be yellow leaves, breeding should pay attention to the environmental ventilation performance, generally grow more than 2 years hibiscus has higher requirements for the environment, poor maintenance, it is easy to appear yellow leaves. 3, hibiscus growth light-loving, spring and autumn can be directly placed in the sun maintenance, summer sun exposure is too strong, easy to burn leaves, should be properly shaded, insufficient light can not provide plant photosynthesis nutrients, branches spring source leaves are long and soft, easy to occur yellow leaves, appropriate scattered light can also promote the growth of plants. 4. Hibiscus needs a lot of nutrients when flowering in spring, when the supply of water and light is insufficient, it is necessary to fertilize appropriately, and ammonia fertilizer can be applied after pruning the flowering plants.

What's going on with the yellowing of the leaves of the hibiscus.

Hibiscus is a plant in the Malvaceae family, and when its leaves turn yellow, it is usually caused by overwatering, too much light, improper fertilization, etc.

A common cause of yellowing of hibiscus leaves.

1. Watering: Hibiscus likes to be moist, although it is drought tolerant, but long-term lack of water will cause the leaves to turn yellow, especially in summer, it is easy to dry up due to lack of water due to dry roots. If you water too much, the roots will rot and yellow leaves will appear.

2. Light: If the little finger chain coarse hibiscus is placed in a dark environment for a long time, it cannot photosynthesize, which will affect the accumulation of chlorophyll and cause yellow leaves.

3. Temperature: If the temperature is too high, the moisture of the leaves will evaporate quickly, causing the leaves to turn yellow, and if the temperature is too low, the hibiscus will be frostbitten, and the leaves will also turn yellow.

How to treat the yellowing of hibiscus leaves.

1. Watering: Hibiscus summer is the high incidence period of yellow leaves, at this time, the potted plants should be moved to a ventilated and scattered place, and watered in time. But don't water too much, just keep the soil moist.

2. Nutrients: The leaves caused by insufficient nutrients will turn yellow, and the hibiscus should be repotted in time, and then repotted once every 1 or 2 years, so as to facilitate the flourishing growth of the root system.

3. Pests and diseases: The yellow leaves should be cut off in time when there are pests and diseases in hibiscus, pay attention to ventilation, and spray with dimethoate or carbendazim for control.

Prevents yellowing of hibiscus leaves.

After the spring flowering of the hibiscus, a quarter of the branches should be pruned in time, and then nitrogen fertilizer should be added once, and thin fertilizer should be applied frequently to ensure the good growth of the hibiscus and prevent the leaves from yellowing.

<> hibiscus yellow leaves, is caused by too strong light, insufficient nutrients, watering discomfort and other reasons, when breeding hibiscus, it is necessary to place the plant in the scattered light, to avoid it by strong direct light, and to apply phosphorus and potassium fertilizer once a month, so that the hibiscus leaves restore verdant green, and according to the degree of soil dryness and wetness to water, to maintain the normal growth of hibiscus.

1. The light is too strong.

Hibiscus is not tolerant to strong direct light, it will turn yellow when the light is too strong, when cultivating hibiscus, it is necessary to place the plant in a place that can irradiate the scattered light to promote the healthy growth of the plant, or to do a good job of shading measures for the hibiscus, the rental bush can be covered with a shade net above the plant, so as not to burn its leaves.

2. Insufficient nutrients.

When cultivating hibiscus, if the fertilization is too little, or the fertilizer is too simple, it will lead to malnutrition of the plant, which will make the leaves of the hibiscus yellow, and it is necessary to apply phosphorus and potassium fertilizer every other month during the growth of hibiscus, and regularly spray potassium dihydrogen phosphate on the leaves of the hibiscus to delay the senescence of the plant.

3. Watering discomfort.

Hibiscus likes water, but does not like waterlogging, when cultivating hibiscus, if watering is too frequent, it will cause the plant to rot in water, so that its leaves will wither yellow, and if watering too little, it will cause the leaves of hibiscus to wither yellow, and it needs to be watered according to the dryness of the soil to keep the soil moist.

4. Maintenance method.

When maintaining hibiscus, it is necessary to prune the branches and leaves of the plant regularly, you can cut off the dead yellow leaves of the hibiscus to avoid the loss of excess nutrients, and cut the branches and leaves that are too dense to improve the light transmission and ventilation between the plants, and change the potting soil for the hibiscus every 1-2 years.

Generally speaking, there are three reasons for the yellow leaves of hibiscus. First of all, it may be caused by too little watering, although it is said to be able to tolerate a certain dry environment, but long-term drying will cause the plant to die. Secondly, it may be caused by insufficient light, if the plant is grown in a shaded and airtight environment for a long time, the plant is prone to malnutrition.

In the end, it may be that the plants are not pruned.

1. It may be caused by improper watering.

Many people may know that hibiscus flowers like a warm and humid environment, so when maintaining hibiscus, it is necessary to provide a warm and moist environment that is conducive to growth, but if you water it too much or too little when watering, it will cause the leaves of the hibiscus to turn yellow due to insufficient watering, so you must pay attention to controlling the amount of watering to water the hibiscus and keep the soil moist.

2. Reasons for improper fertilization of hibiscus.

Hibiscus naturally needs to be fertilized from time to time when it grows, because if it is not fertilized for a long time, it will make the hibiscus flower unable to grow normally due to lack of fertilizer, and the leaves will turn yellow. And if you fertilize too much when raising hibiscus flowers, it is not good, and it is easy to let the strong fertility cause root burning and yellow leaves to the roots of the flowers. Therefore, as long as it is properly fertilized when raising hibiscus, hibiscus flowers will generally be fertilized with phosphorus and potassium fertilizer, and a little auxiliary nitrogen fertilizer will be fine.

3. Pests and diseases make hibiscus flowers appear yellow leaves.

For hibiscus, if there is no problem with normal maintenance that makes its leaves yellow, it is likely that the hibiscus flower has pests and diseases, and the hibiscus flower will be infested by pests and diseases. For example, leaf blight can cause the leaves of hibiscus flowers to turn yellow or even wilt, while aphids can bite the leaves of hibiscus flowers, causing the leaves to turn yellow due to the lack of leaf juice due to the bite of aphids.

4. The reason for changing pots during the flowering period makes the leaves of hibiscus flowers turn yellow.

When maintaining hibiscus, if you want the hibiscus to grow normally, it is also a very important step to repot the hibiscus, but when you repot the hibiscus, you should pay attention to the time, if you change the pot of the hibiscus at the wrong time, it will make the hibiscus grow badly. For example, in the flowering period of hibiscus flowers to repot the hibiscus flowers, at this time the hibiscus flowers are using all the nutrients for the growth of buds and flowering, if the repotting is carried out, it will have a certain impact on its roots, so that the roots can not supply the normal demand for nutrients, and it is easy to make the leaves of the hibiscus flowers yellow.

Hibiscus syriacus (scientific name: hibiscus syriacus) is usually in full bloom during the summer stool season, and is also known as the August cannon. Its leaves are thicker and more beautiful, but if you notice that your hibiscus leaves are starting to turn yellow, or even dry up and fall off, then you need to consider the cause of this problem.

In general, there are various reasons for the yellowing and wilting of hibiscus leaves.

First of all, lack of water or poor drainage is the most common cause of yellowing of the leaves. Hibiscus is a plant that prefers sunlight and moisture, and if the soil is dehydrated or poorly drained, it will cause the roots and leaves to lack moisture, which in turn will cause the leaves to yellow.

Secondly, soil quality problems can also cause the leaves of hibiscus to turn yellow. If the soil acidity is too high or too low, it will have a certain negative impact on the growth and development of hibiscus, it is recommended to carry out soil pH test, if there is a problem, you need to adjust the soil pH to provide a more suitable environment for the growth of hibiscus.

In addition, yellowing of hibiscus leaves may also be due to pests and diseases. For example, pests such as hibiscus cyclotrons, aphids and spider mites can cause damage to the leaves of hibiscus, and the lack of bridges can cause yellowing of the leaves. At the same time, hibiscus is also susceptible to fungus and bacteria such as gray mold, black spot and leaf spot, which can also cause yellowing and dryness of leaves.

Finally, yellowing and wilting of hibiscus leaves may also be due to insufficient or excessive fertilizer. During the growth of hibiscus, if the necessary nutrients are not available for a long time, the leaves will turn yellow, and in severe cases, the plant may even die. On the contrary, if the fertilizer is excessively applied for a long time, it will cause damage to the root system of the hibiscus, causing the leaves to turn yellow and dry.

All in all, there are many reasons for the yellowing and wilting of hibiscus leaves, which need to be comprehensively analyzed and considered. If you find this happening with hibiscus, look for problems with water shortages, poor drainage, soil quality, pests and diseases, and fertilizer problems. Only by finding the right cause can we solve the problem in a targeted manner and help the hibiscus to regain healthy growth and bloom beautiful flowers.
