Treatment methods of yellowing of common flower leaves

For flowers, if there is yellowing and chlorosis of leaves, it means that there are already some problems in flowers, and there are actually many reasons for flower leaves yellowing. Generally, too much watering and too much fertilizer are the most common. So how to deal with the yellowing of flower leaves?

Excessive or inappropriate application of chemical fertilizer will cause leaf wilting and yellowing (fertilizer damage). If there is too much chemical fertilizer at one time, or the soil moisture is insufficient, after fertilization, the concentration of fertilizer solution in the soil is high, causing reverse osmosis of water in flower cells, causing flower dehydration and wilting, resulting in serious death. When some chemical fertilizers, such as ammonium bicarbonate, are applied in the case of high temperature, it is easy to produce a large amount of ammonia, burn the leaves of flowers, turn yellow in the lower leaves of light flowers, and wither the whole plant in heavy ones. Therefore, the application of chemical fertilizer should not be too much at one time, and the amount of urea per mu should not exceed 10 kg. Depending on the size of the pot, it is appropriate to apply 1.5 Mel 1.0 grams per pot.

Watering too often or continuous rain for a long time makes the soil in a state of stagnant water for a long time, resulting in the reduction of oxygen in the soil, which can not meet the needs, leading to abnormal life activities of flowers, causing leaves to yellowing or even wilting, at this time, it is required to stop watering or avoid rain and let the soil dry, so as to improve soil ventilation, increase oxygen content, reduce the toxic effect of excessive soil carbon dioxide on flowers, and make flowers grow normally.

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.

Flower friends, have you learned?

What about the yellowing of flower leaves? the reasons for the yellowing of 11 kinds of flower leaves.

The causes of flower leaf yellowing are water yellow-dry yellow-light-hungry yellow-fat yellow flower leaves yellowing, but also affected by soil pH, diseases and insect pests, drug damage, smoke and dust, humidity, imbalance of trace elements in soil, poor ventilation and other factors can also cause leaf yellowing. As for the metabolism of branches and leaves, the temporary imbalance of nutrient water after transplanting and the withering of leaves during dormancy are normal physiological phenomena of plants. The following common leaf yellowing analysis

Common causes of yellowing of flower leaves 1. Overwatering

The basin soil is too wet for a long time, which causes anoxia in the soil, causes some fibrous roots to rot, hinders normal respiration and absorption of water and nutrients, and causes leaves to turn yellow and fall off. After the injury, the young leaves turn pale yellow, and then the old leaves gradually turn yellow. watering should be controlled immediately, fertilization should be suspended, and the soil should be often loosened to make the soil well ventilated.

2. Drought dehydration

Flower cultivation leakage watering or long-term watering half waist water (that is, upper wet and lower dry) will affect nutrient absorption, and it is also easy to cause dull and dull leaves and drooping leaves. First, the lower old leaves aged, and gradually withered and yellowed off from the bottom up. At this time, a small amount of watering and spraying is needed to gradually recover and then turn to normal watering.

3. Lose weight for a long time

There is no application of ammonia fertilizer or no change of soil for a long time, and there is a lack of nitrogen and other nutrients in the soil, resulting in thin branches and leaves and thin and yellow leaves. It is necessary to pour the pot in time and gradually apply rarefied mature liquid fertilizer or compound flower fertilizer into new loose and fertile culture soil.

4. Excessive fertilization

If you fertilize too much, the new leaves will be thick and uneven, and the dry tips of the old leaves will fall off. You should immediately stop fertilization and increase the amount of water to make the fertilizer flow out from the drainage hole at the bottom of the basin, or immediately pour the pot, rinse the soil block with water and then plant it again into the basin.

5. Hot and high temperature

In summer, if you put cool flowers (such as cyclamen, Golden Bell upside down, four Seasons Begonia) in a high temperature place to let the strong light shine directly, it is very easy to cause the young leaf tip and leaf edge to scorch, or the leaf yellow to fall off. Move to a well-ventilated shady place in time.

6. Excessive covering of yin

If the sun-loving flowers are kept in shade or lack of light for a long time, it will cause the branches and leaves to grow, the leaves are thin and yellow, and they do not blossom or rarely bloom. Be careful to move the flowerpot to the sunny place.

7. Alkalinity of soil and water

There are more saline and alkali in soil and water in most areas of northern China, and flowers with acid-like soil are planted, such as rhododendron, camellia, Michelia, gardenia, orchid, magnolia, sweet-scented osmanthus and so on. Due to the lack of soluble iron and other elements that can be absorbed by the soil, the leaves will gradually turn yellow. Acid soil should be selected when planting, and alum fertilizer and water should be often watered during the growth period.

8. Airtight

If too much nitrogen fertilizer is applied, the branches and leaves will grow luxuriantly, coupled with the long-term unpruned, resulting in insufficient light in the inner chamber branches and leaves, which is easy to cause the leaves to yellowing and falling off. Reasonable fertilization should be applied and pruning should be strengthened to make it ventilated and transparent.

9. Air drying

When the indoor air is too dry, some flowers that like the humid environment, such as hanging orchids and orchids, often appear leaf tip dryness or leaf edge scorching and so on. Attention should be paid to water spraying, plastic film cover and other methods to increase air humidity.

10. Improper temperature

If the room temperature is too low in winter, the flowers are often vulnerable to cold damage, which leads to the yellowing of the leaves and death in severe cases. If the room temperature is too high, the transpiration of the plant is too high, and the root water and nutrients are in short supply, the leaves will turn yellow. Please pay attention to adjust the room temperature in time.

11. Soil partial acidity

It is easy to lose acid and magnesium in southern red loam. planting flowers and trees with alkali-tolerant or mute soil, such as oleander, yellow poplar, Yingchun, etc., are often prone to green and yellowing between the veins of old leaves. Can apply calcium magnesium phosphate fertilizer or spray magnesium sulfate solution.
