What s the deal with the yellowing of hibiscus leaves?

The yellowing of the leaves of the hibiscus flower is caused by improper maintenance, and the hibiscus flower is a common flower, which is often used in greening, such as roadside green belts, urban residential areas, etc. Hibiscus flowers are also suitable for home farming, and they can be planted in pots and placed on their own balconies. So, what's the deal with the yellowing of hibiscus leaves?

1. Improper watering.

Hibiscus is slightly drought tolerant, it does not like large water, as long as there is water in the daily soil, that is to say, we have to keep the soil slightly moist. If there is not enough water in the soil and the leaves of the hibiscus flower cannot absorb the water, then its leaves will turn yellow and look listless; If you water too much at once, there is water in the soil, and the ventilation is not good, then the root system of the hibiscus flower is prone to rot, and then it will cause yellow leaves. Daily watering of hibiscus flowers should pay attention to the amount, see dry and wet, plant lack of water and timely watering, open hibiscus flowers in the rainy season to pay attention to drainage.

Second, apply thick fertilizer.

Hibiscus needs to be fertilized during the growth period, especially before the flowering period, because flowering needs to consume a lot of nutrients, so we need to fertilize properly during the flower bud differentiation period to promote the differentiation of hibiscus flower buds, if the plant lacks fertilizer, its leaves are easy to yellow, but it can not be fertilized excessively, if the fertilizer is excessive, it will lead to root burning, which will also cause the phenomenon of yellow leaves. When the hibiscus flower is overfertilized, it is necessary to water it once to dilute the fertilizer in the soil, and if it does not work, it can also be solved by changing the pot. <>

3. Pests and diseases.

In spring, summer and autumn, hibiscus flowers are more prone to pests and diseases, especially the weaker plants, after the occurrence of hibiscus pests and diseases, its leaves will turn yellow, the plant will become thinner and weaker, and the later stage will also affect flowering. In order to control pests and diseases, we should observe the plants more during the growth period to see their growth. It is also necessary to pay attention to the plants around the hibiscus flower, and if there are pests and diseases, they should also be controlled in time to avoid infection.

The flowers of the hibiscus flower resemble peony flowers and also resemble hibiscus, and its flowers look delicate, like a little girl. Hibiscus flowers are suitable for planting in the courtyard or balcony, and it can grow well with moderate sunlight and sufficient moisture in the soil.

There are several reasons for this:1. Improper light: insufficient or too strong light will affect the photosynthesis of camellia and cause yellow leaves.

2. Insufficient fertilization: The growth of camellia leaves requires potassium, and too little fertilization will cause yellow leaves.

3. Water accumulation in potting soil: water accumulation leads to root rot and affects the growth of camellia.

4. The temperature is too high: the water evaporates too quickly at high temperature, which affects the growth of leaves.

The yellowing of hibiscus leaves is mostly due to excessive water, so it is enough to control watering and ventilate more.

The flowering period of hibiscus flowers is in summer and autumn, once the flowers are large and brightly colored, they are deeply loved by people, but many people in the process of breeding, there will be the phenomenon of yellow leaves of hibiscus leaves, even if the flowers are beautiful, the ornamental plummeting decline, what should be done at this time.

1. Watering. Osmanthus likes a warm and humid environment, but once Hongsun waters too much, it is easy to accumulate water and hurt the roots, if you water too little, it will be due to insufficient water, and the leaves will turn yellow, so you must control the amount of watering when watering, and keep the soil moist at all times.

2. Fertilization. If less or no fertilization is applied when fertilizing, it will make the hibiscus flowers because of the lack of fertilizer yellow leaves, and the application of too much fertilizer will easily cause root burning and produce yellow leaves, so we must pay attention to the correct amount to make the hibiscus flowers grow better.

3. Pests and diseases.

If there is no problem with normal maintenance, it is very likely that there are pests and diseases in the hibiscus flower, but the hibiscus flower with pests and diseases, its leaves slowly turn yellow and wither, and there are traces of aphid bites on the leaves.

4. Change the pot. If it is not suitable to change the pot, it is easy to have yellow leaves, and it must be forbidden to change the pot during the flower type period.

Hibiscus is a common ornamental plant, its leaves are green, the flowers are bright, the ornamental value is particularly high, suitable for planting in garden scenic spots and courtyards.

However, in the production process of hibiscus, the leaves often turn yellow, and the yellowing of its leaves will affect the normal growth and also affect its ornamental value, so what makes its leaves yellow?What should I do with it when its leaves turn yellow?

What should I do if the leaves of the hibiscus flowers are yellow1.

Hibiscus is a green plant that likes a warm and humid environment, in the process of its growth, if the watering is not reasonable, it will cause its leaves to turn yellow, normally, Lingbo slag in the normal growth of kapok, as long as the soil is kept moist, if the soil is too dry or too wet, it will make its leaves yellow, then the best way to deal with it is to control the amount of watering, and in the English high incidence weather to do a good job of drainage.

2. Fertilization is not reasonable.

Improper fertilization of hibiscus flowers during the growth process, and when it appears too much or too little fat, it will also cause its leaves to turn yellow.

The fertilizer applied to hibiscus flowers during the growth process should be mainly phosphorus and potassium fertilizer, and if it appears that the leaves turn yellow, it should be supplemented with the application of appropriate nitrogen fertilizer.

If the leaves turn yellow because of too much fertilization, you need to water the fertilizer in time.

3. Pests and diseases.

The appearance of pests and diseases is also the main reason for the yellowing of the leaves of hibiscus flowers, some diseases will leave a large number of small black spots on the back of the leaves, and the leaves will turn yellow when they are serious, at this time it is necessary to spray drugs in time, it is best to spray mancozeb, when the drugs eliminate all the pests on the hibiscus flowers, its leaves will slowly return to normal color.

4. Root system damage.

Usually if people make hibiscus into potted plants, in indoor breeding, it is necessary to replace new pots every year, when replacing pots, if you accidentally damage the renewal of hibiscus, and then move into a new pot, it will also cause the leaves of hibiscus to turn yellow and fall off, this is the best treatment, is to put hibiscus in a cool environment to slow down the seedlings, and after its root system returns to normal, it will grow new green leaves.

1. Improper watering: excessive water will make the new leaves of hibiscus flowers turn pale yellow, and the old leaves will turn yellow and fall off. 2. The light is too strong:

Exposing it directly to the sun will burn the leaves. 3. Infection with pests and diseases: After being eroded by pests and diseases, a large number of yellow spots will appear on the leaves.

4. Improper fertilization: mainly due to excessive fertilizer concentration and excessive fertilization.

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.

Hibiscus flowers are always yellow leaves, which may be caused by overwatering, you need to control the frequency of watering, you can wait until the soil surface is white before watering, and pruning in the spring of each year, you can cut off the wilted and yellowed leaves of hibiscus, and place the hibiscus flowers in a bright place to promote its synthesis of chlorophyll.

1. Control watering

Hibiscus flowers are not resistant to waterlogging, when cultivating hibiscus flowers, if you water too much, it will cause the root system of the plant to rot in water, so that the leaves of the hibiscus flowers are yellow, you need to wait until the soil surface is white before watering, and when watering the hibiscus flowers, you need to let the tap water stand for 1-2 days before use.

2. Pruning

When cultivating hibiscus, it is necessary to prune in the spring of each year, and the branches and leaves that are too dense can be cut off to improve the light transmittance and ventilation between plants, and the wilted and yellowed leaves of the hibiscus should be removed to reduce the loss of nutrients and promote the growth of green new leaves.

3. Lighting conditions

Hibiscus is a sun-loving plant, it can grow normally in a bright environment, when cultivating hibiscus, it needs to be placed in a place where it can be exposed to sunlight to promote photosynthesis of plants, but when the light is too strong, it is necessary to do shade measures for hibiscus flowers to avoid its leaves being burned.

4. Maintenance method

When maintaining hibiscus, it is necessary to apply nitrogen fertilizer and phosphorus fertilizer to the plant after flowering to make the flowers of hibiscus more brilliant, and spray potassium dihydrogen phosphate on the flowers and leaves of hibiscus to delay the senescence of the plant, and in winter, move the hibiscus to an indoor temperature higher than 10 degrees.

<> hibiscus for water requirements is not very high, during the growth period to keep the courtyard moist, not drought can, if the watering is too little or the rainy season does not pay attention to the water in the courtyard, it will cause the leaves of the hibiscus to yellow and fall, timely hibiscus on the watering requirements are not strict, we should also maintain a heart for the growth of hibiscus, should not accumulate is the principle of hibiscus watering.

Vigorous growth, full of beautiful flowers is the hope of every flower friend who plants hibiscus, so it has also led to many people will fertilize a lot of hibiscus, resulting in yellowing of hibiscus leaves, poor growth, hibiscus fertilization with phosphorus and potassium fertilizer as the main fertilizer, supplemented by nitrogen fertilizer for reasonable top dressing, if too much fertilization will make the fertilization thick, burn the root system, make the leaves yellow and fall, if the daily fertilization finds that the hibiscus leaves are yellow and fall, it is necessary to pay attention to whether it is a problem caused by too much fertilization.

Aphids are one of the more common insect pests of hibiscus, which has caused serious harm to the growth of hibiscus. Aphids suck the sap from the leaves, and too much sucking can cause the leaves to gradually turn yellow and wilt. Therefore, aphids are also an important reason for the yellowing of leaves, if so, it is necessary to spray pesticide sprays in time for treatment;

Similarly, disease is also an important factor in the yellowing and wilting of hibiscus leaves, especially leaf blight. Leaf blight is characterized by the production of many small black lesions on the back of the leaves, and the use of sprays such as mancozeb can restore the leaves to normal.

The healthy extension of hibiscus is inseparable from repotting, but changing the pot needs to grasp the timing, the flowering period of hibiscus is forbidden to change the pot, the most likely cause of repotting is to cause certain damage to the root system of the hibiscus, once the root system is damaged, the flowers and leaves of the hibiscus will receive certain damage, resulting in the yellowing of the leaves and falling off.
