This kind of flower likes yellow leaves in spring. Cut it and water it for three days and it will be green!

Watering often causes leaves to turn yellow.

Some people grow flowers and always like to water them more. They can't wait to water them once a day. After a long time, if the leaves turn yellow, it is yellow water caused by too much watering!

Symptoms:

Yellow leaves caused by excessive watering. The veins are green, but the leaves are obviously yellow, and gradually turn yellow from the tip of the leaf. In addition, the new leaves grow slowly in Huang Liang, and the old leaves gradually turn yellow and wither.

If it is yellow leaves caused by excessive watering, nine times out of ten there will be problems with the roots. Pull it out and have a look. Most of the roots are rotten by water! Author |C Jun forgot

Solution:

1。 Take the god of wealth tree as an example. The yellow leaves of the rich tree were found. After inspection, it was found that it was caused by excessive watering. Stop the water quickly and put it in a well-ventilated place to let the excess water in the basin evaporate as soon as possible. If there is too much water, you can also take the rich tree out of the basin, let the roots and soil in the basin dry, and then put it in the basin. 2. If the stem is softened and there is black rot near the root system, it is accompanied by rotten roots. Take the rich tree out of the pot, clean the soil on the root system, check the rotten part of the root system and cut off the black rot. 3. Put the lower end of Fu Guishu into carbendazim solution for sterilization and disinfection. If it's too much trouble, you can also sprinkle some carbendazim powder directly on the wound. The sterilization effect is also quite strong. 4. Serve again. When in the basin, pay attention to laying tiles on the bottom of the basin to increase water permeability and prevent water from rotting the roots. Try to choose loose and breathable nutrient soil for basin soil. If the water permeability is good, watering more will not rot the roots and the leaves will not turn yellow! If you want to avoid the yellow leaves caused by accumulated water and rotten roots at home, you should pay attention to daily watering. If it is a small flower, such as green radish, chlorophytum, hawksbill, etc., you can weigh the flowerpot and water it when it feels obviously lighter. 6. If you can't move the flowerpot at all, such as the rich tree, the happy tree and other big flowers, find a chopstick, poke it 3-5cm under the pot soil, pull it out and find that the pot soil is dry, and then water it. In this way, we can roughly judge whether the flowers at home should be watered or not, and prevent water and rotten roots from causing yellow leaves.

Without water, the leaves are yellow and faded!

Some flower farmers are busy for ten days and a half and are not at home. If the flowers raised at home are not particularly drought-tolerant, nine times out of ten, the yellow leaves will wither and even die directly!

Yellow leaf symptoms:

Yellow leaves caused by water shortage are mainly old leaves withered, falling off from bottom to top, leaf tips and edges withered and wilted, leaves drooped, and even the whole pot of leaves dried up!

What if there is water shortage?

1。 If the water shortage of flowers is not serious, but the stems are drooping, like longevity, then put a tray under the flowerpot, add water to the tray, and squat for longevity without watering. 2. If, like Lysimachia christinae, not only the stems wither after lack of water, but also there will be many yellow leaves, then be cruel, find a pair of scissors and cut off all the roots 2-3cm on the surface of the basin. This is called baldness. Put the bare Lysimachia christinae in a sunny place, and remember to ensure sufficient water. In a week or so, you can see that it has small leaves, and within a month, it can become a green pot again!

Yellow leaves caused by lack of fertilizer

The temperature rises in spring, which is a good time for flowers to grow wildly. If enough fertilizer is added, it will grow wildly, but if there is not enough fertilizer, it will also cause the leaves to turn yellow!

Symptoms:

If nitrogen fertilizer is lacking, it will be found that the color of the whole leaf becomes lighter, and the old leaves turn yellow from the tip of the leaf and gradually expand like new leaves, while the newly grown leaves are dull and the stems are short and thin, indicating the lack of nitrogen fertilizer.

How to improve the phenomenon of fertilizer deficiency?

1。 Pour some homemade soybean water and peel water. If you find that the flowers at home are short of fertilizer and the leaves are yellow, you should supplement nutrition in time, such as homemade soybean water and peel water.

2. Flower lovers who don't want to make their own fertilizers, such as Huaduoduo 1 or Austrian green slow-release fertilizers and compound fertilizers, can also try to buy Huaduoduo 1 or other slow-release fertilizers and compound fertilizers. When watering every time, add some water in proportion, and water every 10 day, which can also supplement nutrients for flowers and reduce the yellowing of leaves. 3. Add some base fertilizer when changing pots. When changing pots and growing flowers in spring, you can also add some basic fertilizers to supplement nutrition, such as chicken manure, sheep manure, cooked soybeans and slow-release fertilizers. You can grab a handful and sprinkle it directly in the pot, so that nutrients can be released slowly in the soil and the yellow leaves can slowly recover.

Yellow leaves caused by fertilizer damage

Contrary to the lack of fertilizer, if fertilizer is applied in spring, the concentration is too high, or raw fertilizer is fed, the leaves will turn yellow.

Symptoms:

Excessive fertilization will lead to excessive fertilizer, which will lead to seedling burning, overgrowth, lodging, wilting and even serious death. If you look at the leaves carefully, you will find that the leaves are a little black and yellow, and there are some burnt edges, which are completely different from the yellow-green that lacks fertilizer.

How to solve the fat damage?

1。 Take gardenia as an example. If the pot soil is fertilized too much, or the original fertilizer is used to cause fertilizer damage, root irrigation should be carried out in time, that is, a large amount of water should be poured, which is generally 5-8 times the capacity of the flowerpot. Then put the flowerpot in a well-ventilated place, wait for the soil to dry thoroughly, and continue to water the roots. Repeat for 2-3 times, so that all the excess fertilizer in the soil is washed away. 2. If the fertilizer damage is particularly serious and there is no way to solve the problem of root irrigation, then directly wash the roots and change the soil, clean the soil on the roots, put it under the faucet, and wash the fertilizer on the roots. Then change the clean soil and put it in a well-ventilated place to slow down the pot. Relax, the new leaves will be healthy! 3. When fertilizing flowers daily, everyone must pay attention to thin and diligent fertilization, and the concentration should not be too high; If self-made fertilizer is used, it must be retted for 1-2 months, and then used after the fertilizer is completely decomposed. Don't fertilize directly, or you will be fattened again.

Iron deficiency causes leaves to turn yellow.

Another reason for the yellowing of flowers and leaves at home is the lack of trace elements, especially iron, which is one of the special needs of flower growth. Once lacking, it will appear on the leaves, the most obvious is the yellow leaves.

Main symptoms:

Iron is an important component of chlorophyll synthesis in leaves. If the flowers at home are short of iron, the leaves will turn yellow, indicating that the tender leaves and mesophyll turn yellow, but the veins are still green. The whole leaf has a grid structure, then the leaves turn yellow and white, and the veins gradually turn yellow.

Iron-deficient yellow leaves of Fuguizhu

:0 10 1。 If the flowers at home have yellow leaves because of iron deficiency, the easiest way is to pour some ferrous sulfate, generally according to 1: 10. 2. If you have rusty nails at home, you can also put them in a bottle and soak them in water for more than 1 week. /kloc-soaking in nail water once a day can also effectively alleviate iron deficiency. 3. If the hydroponic flowers lack iron, you can directly throw the rusty nails into the bottle and let the rust slowly release in the water. You can also add iron to the flowers to prevent the leaves from turning yellow. 4. In daily watering, you can also add some white vinegar or citric acid to the water to improve the pH of the soil, and it can also effectively improve the iron-deficient yellow leaves, especially the acid-loving flowers such as gardenia, jasmine, camellia and rhododendron. In addition to iron deficiency, if there is a lack of certain elements, plants will also turn yellow, and the symptoms of yellowing are different. You can compare them according to the pictures.

How to solve iron deficiency:

As the weather gets hotter and hotter, those flowers that like to scatter light should not be directed at noon, otherwise it is easy to burn the leaves. You can tell if you are sunburned by looking at the leaves.

Too much light will burn the leaves.

Sunburned leaves, the edges and edges of the leaves will be dry and scorched, as if they were burnt, and the leaves

Yushu sunburn:

Hydrangea sunburn:

1。 When you find that the flowers at home are sunburned and have black spots, you should cut off the leaves with yellow black spots in time. These injured leaves can't be recovered. When they stay on plants, they still consume nutrients. Take it off. 2. For some flowers that like to scatter light well, such as hydrangea, Hosta, White Palm, etc. When the weather gets hot, move to a bright place indoors. Avoid direct sunlight and prevent the leaves from getting sunburned. 3. If the flowers planted outdoors, or the flowers raised in Nanyang Terrace, are afraid of sunburn in summer when it is particularly hot, you can also pull a sunshade net for them, or cover them with an umbrella when it is particularly hot at noon to achieve the purpose of sunshade. In addition to sunburn, the light at home is not good, and the leaves will turn yellow if you don't bask in the sun for a long time. At this time, you should move to a place with good light to get more sunshine, and you will recover after a while. Like this pot of Lysimachia christinae, the leaves turn yellow because of insufficient indoor light. Just move outside and get some sunshine.

What if you get sunburned?

Roses, green radish, rich trees and other flowers. Once caught, pests and diseases will be directly displayed on the leaves, because many insects like the twigs of leaves. Once they start biting the leaves, it will cause bacterial infection on the leaves. Everyone knows to recruit bugs from leaves!

Diseases and pests cause leaves to turn yellow.

Once the flowers at home are infected with diseases and insect pests, the tender leaves are the most susceptible to infection, which are generally characterized by yellowing, yellowing, even necrosis, wrinkling and deformity. In severe cases, it will fall off as soon as it touches the leaves.

Symptoms:

Rose pests and diseases:

1. If spots are found on the leaves, it is probably a fungal infection. For example, you can spray carbendazim and chlorothalonil. If it's too much trouble, you can also spray them with onion water and pepper water. 2. If it is caused by spiders, aphids and other pests, you should buy special drugs for treatment. Red spider can choose to use two drugs alternately, Jin Manzhi and Icarus, to prevent insects from developing drug resistance, while aphids can be killed with imidacloprid.

How to treat it?

The simplest and straightforward reason for the yellowing of leaves may be natural aging, that is, a pot of flowers will slowly turn yellow and fall off. If only the bottom 1-2 leaves turn yellow, nothing else will happen, which is natural aging. Take it off, don't worry. Author | Return to Heaven
