Prevention and treatment of yellowing of flower leaves

In the process of flower growth, it is easy to cause the leaves to turn yellow for various reasons. At this time, we must find out the reason before treatment, so that the flowers can recover as soon as possible. The editor will introduce to you the causes and control methods of three common yellow leaves of flowers, which can be learned by flower friends in need.

Cockscomb flower

1. Due to the drooping leaves due to lack of water, water should be sprayed on the leaves immediately to speed up the absorption of water by the plant, and then water should be watered in the basin. Pay attention to less watering at this time to make the soil moist, and do not water more.

2. In potted peanuts, long-term non-fertilization or insufficient fertilization will cause the phenomenon of yellow leaves; applying too much concentrated fertilizer will burn the roots, affect water absorption, and also cause yellow leaves, which can be diluted and washed away from the soil. The lack of fertilizer can lead to basin soil hardening, leaves yellow, thin, thin, branches slender, yellow, tender, should be fertilized immediately. At the same time, spraying Huazhuangtiling can make the buds strong, the petals enlarged, the flowers colorful, the flowers fragrant and the florescence prolonged.

3. Diseases and insect pests are harmed by mosaic virus. Yellow and green plaques appear on the leaves after mosaic virus infection. Attention should be paid to prevention, spraying new high lipid film in time and giving sufficient light and ventilation. Aphids and red spiders absorb nutrition and water on the back of the leaves, so that the leaves are withered and yellow and even the leaves of the whole plant wither and fall off, which can be recovered by killing insects in time.

Prevention and treatment of yellowing of leaves of family flowers

In the process of flower growth, the leaves often turn yellow, which is mostly caused by the imbalance of cultivation and management. Too much water, too little sunlight and too little fertilizer will cause leaves to turn yellow, but the situation of yellowing is different, so we should carefully observe and analyze the causes and manage them in time.

First, the tender leaves are dark yellow and dull, the old leaves have no obvious change, the branches are small and yellow-green, and the new shoots are not long, indicating that they are overwatered. Remove the flowers from the pot and place them in a ventilated, cool, self-drying soil mass and then put them back into the basin.

Second, the dry yellow is different from the water-deficient yellow, the water-deficient yellow is withered and dry at the tip or edge of the leaf, and the old leaves wither and fall off from the bottom up, but the growth of the new leaves is relatively normal. Pay attention to watering enough and thoroughly.

Third, the burning yellow and strong sunlight shines directly on some shade-loving flowers (such as hanging orchids, hairpins, etc.), which can easily cause the withering of the tips and edges of the flowers and the macula in the sunrise part of the leaves. Just move to the shade.

Fourth, lack of light yellow for a long time in a shady environment, the leaves can not get enough sunlight, can not form chlorophyll, the whole leaves turn yellow and then fall off, supplementary light can avoid the disease.

Fifth, the yellowing of flowers caused by excessive fertilization or excessive concentration, showing dry brown at the tip of the new leaves, the leaves are generally thick and without luster, and the concave and convex do not stretch, and the old leaves are scorched yellow and fall off. Fertilizer should be stopped immediately and some fertilizers should be washed with a large amount of washing.

Sixth, the lack of fat yellow shows that the color of the young leaves becomes lighter, showing yellow or light green, while the old leaves are more normal or gradually change from green to yellow. Check the basin soil if there is a dry knot phenomenon should change the soil, usually apply thin fertilizer frequently and timely pour some alum water.

Flower leaves yellowing how to avoid plant leaves yellowing simple ways to avoid plant leaves yellowing today is an article about flower leaves yellowing. Here are some simple ways to prevent plant leaves from yellowing. Let's take a look.

Yellowing of leaves has always been a big problem in raising flowers, which makes many flower friends have a headache, especially for novices who encounter symptoms of yellowing leaves and do not know how to treat them at all. So, today, Huahua will introduce some common plant maintenance methods to tell you how to prevent plant leaves from yellowing!

1. Avoid yellowing of wealth trees

Pay attention to fertilization

Rich trees are fat-loving flowers and trees. If there is not enough fertilizer, the leaves will turn yellow easily. When changing the pot every year, add the right amount of base fertilizer to the bottom of the flowerpot to make the root system grow stronger.

Add some ingredients:

The base fertilizer can be made from deciduous humus soil and some garden soil mixed with bean cake dregs and broken bone dregs, but it should be cooked and fermented before use.

Pay attention to the light

Rich trees like the warm and humid environment, can not be placed in the environment without light for a long time, can not be exposed to the sun, especially in summer, every few days, it is necessary to spray water with a spray can to wash the dust off the surface of the leaves, increase humidity and strengthen photosynthesis.

Pay attention to watering

Watering is the key to whether the rich tree can grow well or not. The root system of the rich tree is underdeveloped and is very sensitive to water. When watering too much, it is especially easy to rot. Every time you water it, you must first check the dry and wet condition of the soil, and then water it, otherwise it is very easy to rot the root.

2. Avoid yellowing of green apple

Increase humidity

Green pineapple likes the humid environment, when the environment is too muggy, dry, not ventilated, it is easy to cause the leaves to yellowing.

If possible, you can put the green apple near the humidifier. If not, you can use a spray can to spray the leaves, stems and air roots of the green apple several times a day.

In the pot holder of the green radish pot, add the right amount of water to make it evaporate and increase the humidity of the air.

When the air is seriously dry, you can use plastic bags to cover the whole pot of green turnips to create a small moist environment.

Pay attention to fertilization

If the green pineapple is not fertilized properly, more or less fertilizer will easily cause the leaves to turn yellow.

Huahua suggests that during the growth of green pineapple, you can spray urea to make foliar fertilizer every half a month.

Add some ingredients:

Often pour some rice water, fish tank water, can also promote the green apple to grow more prosperous.

3. Avoid yellowing of sunflower with loose tail

Increase air humidity

When loose-tailed sunflower is dry in the air, it is easy to cause the edges of the leaves to turn yellow, dry and scorched, so it is necessary to spray water on and around the leaves three or four times a day.

Reduce the light

From May to September, sunflower must grow in a semi-shady environment. If the light is too strong, the leaves will turn yellow and scorched. In summer, you can put it in the place of scattered light.

Increase the amount of water

The summer temperature is high and evaporates quickly, if the moisture is insufficient, it is easy to cause the dry tip of sunflower leaves to turn yellow, so it is necessary to replenish water in time.

Add some ingredients:

In order to avoid excessive watering leading to stagnant water at the root, when changing pots for loose-tailed sunflower, you can put some cinder and broken tiles at the bottom of the flowerpot.

4. Avoid yellowing of rich bamboo.

Increase iron element

Iron deficiency is an important reason for the yellowing of rich bamboo. You can go to the flower market to buy a bag of ferrous sulfate to supplement iron.

Add some ingredients:

When you cultivate rich bamboo in water, you can also put a few nails in the bottle.

Reduce the light

The summer light is strong, do not put the rich bamboo in the strong light exposure, otherwise the leaves are easy to dry yellow. When the rich bamboo is cultivated in water in summer, it can be put indoors, and the general light can satisfy its growth.

5. avoid yellowing of Anthurium andraeanum

Increase the light

Sometimes we find that the old and new leaves of Anthurium andraeanum have turned yellow. the possible reason is that the light is too weak. Take a look at the growth environment of Anthurium andraeanum, increase the light appropriately as needed, and pay attention to avoid exposure.

adequate manuring

Lack of fertilizer, weak growth, of course, easy to yellow leaves. To apply fertilizer to Anthurium andraeanum, we generally choose a fertilizer with a ratio of nitrogen, phosphorus and potassium at 1:1:1, diluted a thousand times and irrigated every seven days. You can also buy special fertilizer for Anthurium andraeanum to make it grow better.

Add some ingredients:

In order to make Anthurium grow better, we can bury cooked soybeans in the soil of Anthurium andraeanum, and bury three or four grains in a flowerpot, which is simple, practical and convenient.

6. Avoid yellowing of hanging orchids

Proper watering

Cymbidium likes a humid environment, the soil should always be moist, but there can be no stagnant water, because Cymbidium is a fleshy root system, stagnant water can easily cause root rot. Cymbidium has strong drought resistance, so don't accumulate water if you can do it.

adequate manuring

Green pineapple is fertilized with liquid fertilizer every half a month during the growing season. You can also buy special fertilizer for hanging orchids to make the plants grow more exuberantly.

Add some ingredients:

Hanging orchids can also often water some rice water, fish tank water, expired milk, etc., to promote the healthy growth of plants.

Proper shading

Hanging orchids like the semi-overcast environment, summer to avoid exposure to the sun, indoor scattered light can be maintained. When the air is dry, spray water to and around the leaves.

7. Avoid yellowing of ivy

Increase the humidity of the air

The growth of ivy needs high air humidity, especially in summer, on the one hand, watering the soil in time to keep the soil moist, on the other hand, spraying more water, or putting ivy around the humidifier.

Appropriate amount of fertilizer

In the growing season of ivy, thin cake fertilizer can be applied every two to three weeks, try not to apply fertilizer in summer and winter, and be careful not to get it on the leaves, because the leaves are scorched easily.

Add some ingredients:

Dilute the beer 10 times and spray the leaves of ivy to make them greener.

8. Avoid yellowing of asparagus

Rational watering

If you want to keep asparagus from yellowing, watering is the key. If you water too much, the branches and leaves will easily turn yellow, grow poorly, and easily lead to rotting roots. If you do not have a good grasp of water, you can use the method of alternating between large and small water, that is, pour small water three or four times and then pour through the heavy water again to keep the basin soil moist without stagnant water.

adequate manuring

Asparagus does not need much fertilizer, but it is easy to have yellow leaves if it is insufficient. In the growing season of asparagus, mature organic fertilizer is usually applied every half a month. In addition, we can pour some alum fertilizer to asparagus to promote its healthy growth.

Add some ingredients:

The retting cake fertilizer will be diluted 10 to 20 times to irrigate asparagus, which can make asparagus flourish.

9. Avoid the yellowing of the dragon blood tree

Proper watering

The dragon blood tree likes the warm and humid environment and the environment with plenty of light. In summer, it can be watered every 3 to 5 days to keep the soil moist. Everyone can spray water on the leaves of the dragon blood tree every morning or evening to avoid dry and yellow leaves caused by dry air.

Reduce diseases and insect pests

When the dragon blood tree is put in indoor maintenance, due to poor ventilation, it is easy to recruit red spiders, destroy the green leaves, and make the leaves fade. When discomfort symptoms are found in the leaves, the leaves must be checked in time and treated immediately once they are found. The leaves can be sprayed with dichlorvos or trichloroacarol emulsion.

Add some ingredients:

In order to prevent the dragon blood tree from being infected by red spiders, we can soak the orange peel with water for one day and night, filter and spray the plant, which can play an effective role.
