How to raise flowers in the family, why do you always have yellow leaves?

There are many reasons for the yellowing of leaves: 1. Lack of ferrous sulfate, so the soil contains more alkali. 2. Watering too much and waterlogging is caused.

3. Watering half of the water, each time the water is not thorough, the roots of the plant are in the lower part, and half of the water is equal to no watering. 4. Insufficient light, unable to photosynthesize normally, and not much chlorophyll, so the leaves are yellow. 5. It is also easy to cause high and low water temperature.

6. Generally, if the temperature of flowers is lower than 15 degrees in winter, they should also have yellow leaves. Normal growth above 18 degrees. The fertilizer can be diluted by soaking in water with soybean cake (all-purpose fertilizer) before watering.

Combined with the main reasons for the above problems, it is enough to prescribe the right medicine.

Yellowing of flower leaves is a common symptom in flower culture, mostly caused by the lack of nutrients in the soil, and its performance is different due to the different types of fertilizer lacking, and its specific manifestations are as follows:

1. Nitrogen deficiency: yellow leaves occur first in the old leaves at the base, and soon expand to the leaves in the upper part of the branches.

2. Lack of manganese, sulfur and iron: yellow leaves occur first in the tips of the new parts.

3. Magnesium deficiency: the leaf veins are yellow, while the leaf veins are still green.

4. Phosphorus deficiency: the leaves appear dark green or blue-green, the leaves are sharp and pointed, the leaves are narrow, upright, and the plant grows slowly.

5. Potassium deficiency: the leaf margin is whitish and whitened inward, while the leaf veins and their base are green, and then the whole leaf gradually yellows until brown, and finally withers yellow.

6. Calcium deficiency: the root system is short and thin, and the growth is weak, which causes the whole plant to be weak.

In addition, the yellowing of flower leaves is often caused by comprehensive factors, and the reason for its symptoms is inappropriate human management, such as too much or too little watering, insufficient or too strong sunshine, alkaline water quality or unsuitable water temperature, etc., are important reasons for yellowing leaves.

Lack of sunlight, it may be that there is too much watering, and the temperature is too high to breathe.

Introduce how to use ferrous sulfate when flowers have yellow leaves, and what to pay attention to when using ferrous sulfate.

1. Suitable lighting. The yellowing of the leaves of flowers is most likely caused by poor lighting. If the light is too strong or the sun is not exposed to the sun for a long time, the plants cannot photosynthesize and will appear yellow.

If the sun is too strong and you get sunburned, you should shade the sun as soon as possible and spray water frequently to promote the recovery of the plant. If it is caused by long-term lack of sunlight, it is necessary to increase the light, and more astigmatism in the initial stage to give the plant an adaptation stage, and slowly increase the light.

2. Watering appropriately. The yellowing of flower leaves may also be caused by a lack of water, which consumes a lot of water during the growth period, and there is no stagnant water to replenish the water, and the roots cannot absorb water, and the leaves will appear dry and yellow. If it is caused by this seeding situation, it is recommended to water it as soon as possible to allow the plant to absorb enough water, and the growth will slowly resume.

3. Reasonable top dressing. Flowers and plants consume a lot of nutrients during the growth period, such as early fruiting for a long time without top dressing, the soil is poor, can not absorb the required nutrients, and it is easy to have yellowing after a long time. If this situation is caused, it is recommended to top dressing as soon as possible, select suitable fertilizer varieties according to the growth stage, and use thin fertilizer to supplement fertilizer frequently, so as to promote the recovery of growth as soon as possible.

Note that raw fertilizer must not be applied, otherwise it is easy to produce fertilizer damage and noisy cultivation.

4. Timely temperature control. The cold tolerance of many flowers and plants is relatively poor, if the temperature can not be well controlled after winter, it is easy to frostbite if it is in a low temperature environment for a long time, resulting in yellow leaves. If it is low-temperature frostbite, it is necessary to raise the temperature and control the temperature in time to keep warm.

5. Replace the soil. Flowers and plants are different, and the requirements for the soil are not high. Some plants prefer acidic soils, while others prefer alkaline soils.

If the pH of the soil is not suitable or too sticky, it will hinder the respiration of the root system and cause yellow leaves. The soil should be changed as soon as possible according to the growth habits of the plants to ensure that the soil is suitable.

The leaves of the family raise flowers are yellow, under normal circumstances, they are usually watered frequently, watering more, the potting soil is humid for a long time, the roots are rotten, and the leaves are yellow if they can't absorb the water nutrients.

Precautions for raising flowers at home:

Pay attention to watering, home maintenance potted plants are generally watered more, potted plants are generally dry and wet, before watering to see the dry and humid of the pot soil is better, dry watering can be, the soil is not dry and watering, it doesn't matter if the soil is dry, because the roots also need to breathe, the humidity and air can not enter the soil, the roots are easy to rot due to lack of oxygen, and the leaves will turn yellow after a long time, and then die.

Pay attention to the temperature, most of the potted plants are southern evergreen plants, like high temperature and high humidity, the temperature in the north is a little low in winter, you need to pay attention to heat preservation, try not to blow the cold wind to the plant, and do not put heating on the side, it is easy to burn the leaves. It is better to spray potassium dihydrogen phosphate on the leaves frequently, which can improve the cold resistance of potted plants and promote the greener, brighter and larger leaves of plants.

Pay attention to ventilation and light, potted plants in the family can not be placed indoors for a long time, it takes a period of time to move to a bright and ventilated place on the balcony, it is better to see light and ventilation, there are two weeks, and then put it back indoors in a bright place.

Pay attention to pests and diseases, potted plants in the family are generally poorly ventilated, easy to breed insect pests, mealybugs, red spiders, you can go to the flower shop to see the purchase of a package of plant insecticides or mite net, a pack of watering can spraying, spraying plant leaves and branches, the rest of the potting soil, spraying three or four times a week, basically can get rid of insect pests.

Pay attention to pruning, potted plants are generally woody plants, not afraid of pruning, cut off long branches, pests and diseases, fast-growing plants, must be pruned, the type is full and better-looking, can promote the growth of side branches, but also reduce the occurrence of pests and diseases.

Starting from the two aspects of dehydration and poor ventilation, we will teach you to water properly, prune and thin branches in time, strengthen ventilation, and avoid the phenomenon of yellow leaves in the month.

Teach you three tricks to keep the leaves of green plants from yellowing!

If the flowers and leaves are yellow, you should first figure out the cause and solve the problem according to different reasons.

1. Shade yellow. Because potted flowers are placed in the shade for a long time, the light is insufficient, so that the leaves become thinner, the leaf color becomes lighter or the leaves turn yellow and fall off. Light should be increased gradually.

2. Worm yellow. Affected by red spiders, floating dust, whiteflies and other hazards, the leaves lose green, yellowish, should be sprayed in time to kill acaricides.

Generally speaking, the cause of yellowing of leaves can be found from several aspects such as watering, fertilization, soil pH, light, air, pests and diseases.

1. Improper watering: too little watering and too much watering will cause the leaves to turn yellow, the difference is that when there is a lack of water, the leaves start to wither from the edge and turn yellow, just like the picture below.

When you water too much, the new leaves of the plant turn yellow first, and the old leaves generally do not change much. Like the following.

2. Improper fertilization.

Similarly, too little or too much fertilization can cause yellowing of the leaves. For many people, they always want to make plants eat fat in one go, and unconsciously fertilize too much. At this time, if you look closely, you will find that the front end of the new leaf appears brown, the leaf surface of the old leaf is thick and dull, and even the old leaf is scorched and peeled off.

When too little fertilization is applied or the roots of the plant are not absorbed enough nutrients due to soil compaction, the young leaves of the plant will appear lighter in color, which is the unhealthy yellowish or pale green. If there is a shortage of fertilizer for a short time, the old leaves will be relatively normal, and if there is a lack of fertilizer for a long time, the old leaves will gradually turn from green to yellow.

3. Improper lighting.

Different plants have different light needs, some need light all day, while others only need strong scattered light. Even the same plant, at different stages of growth, has different requirements for light. With too much light, for many shade-loving or semi-shade-loving plants, you can find that the leaf tips and leaf edges of the plants are wilted, and yellow spots appear where the leaves are irradiated.

However, if there is too little light, the leaves lack photosynthesis and cannot synthesize chlorophyll, and the leaves of the plant will turn yellow and then fall off.

4. Improper soil pH.

This is often overlooked by many people, some plants prefer alkaline soils, while others need acidic soils to thrive. Therefore, you must understand the soil preferences of the plants you plant, so that the plants can grow healthily and happily in the soil they like.

1. The solution of improper watering: watering is based on the principle that the soil is dry and wet, that is, the surface of the soil is white and dry, and it is watered thoroughly until there is water flowing out at the bottom. If the soil is too wet and the leaves turn yellow, keep it in a sunny or ventilated place.

In severe cases, remove the plant from the pot and place it in a ventilated place, dry it and put it back in the pot.

2. Improper fertilization solution: fertilization is based on the principle of thin fertilizer and diligent application, generally once every half a month during the growth period, and no fertilization is applied during the dormant period. If you apply too much fertilizer, stop fertilizing immediately and water to dilute the fertilizer so that the excess fertilizer can flow out from the bottom.

You can also transplant some fast-growing grasses to quickly consume excess fertilizer. If the fertilizer is too little, the fertilizer should be supplemented appropriately, and the plants that have not been repotted for two years should be repotted or replaced with new soil.

3. The solution of improper light: understand the demand for sunlight of the plants you plant, so that the plants that should be exposed to the sun are more sun, and the plants that cannot be exposed to the sun are less sunny, and the yellowing of the leaves caused by improper light will be greatly improved.

There are many reasons for the yellowing of flowers and leaves, but the most common ones are.

Improper watering, too dry environment, improper fertilization, improper light, improper soil, so when we cultivate flowers and plants, we should maintain them according to the growth habits of each different plant, and if the watering is improper, the soil should be loosened after watering to avoid water accumulation in the potting soil.

In the process of cultivation, if it is found that the tip of the new shoot of the potted flower has shrunk, the young leaves are pale yellow, and the old leaves have gradually turned yellow, it indicates that the soil has been wet for a long time, the soil is hypoxic, and some roots have rotted. This may be caused by excessive watering, and the potting soil drainage is not smooth enough, or even cloudy and rainy, and the potted flowers have not been exposed to the sun for a long time. The potted flowers with mud should be soaked out of the pot and placed in a cool, ventilated and rainy place, so that it can be quickly breathed and dissipated water, and a little water can be sprayed on the leaf surface at the same time, and the flowers should be restored after 3 to 5 days, and the pot should be re-potted for maintenance.

Hello, first of all, what kind of flower do you want to say? However, the main reason for the yellowing of flowers and leaves in ordinary families is insufficient light and unbalanced watering, which is caused by lack of water, and of course, nitrogen fertilizer is also one thing. Tell you the simple way If the leaves are light yellow, it means that there is a lack of water, if it is very yellow and dry tips, it is a big lack of water.

When raising flowers at home, do not water more, and at the same time look at what kind, some like light, and some like a semi-shady environment. At the same time, the flower fertilizer is applied at the same time. Sometimes watering is too much, causing plant roots to rot and reducing their ability to absorb water and fertilizer; If the light is insufficient and normal photosynthesis cannot be carried out, the light can be adjusted appropriately; Lack of fertilizer, especially trace elements (iron, manganese, etc.), should be applied according to the time of application of flower fertilizer.

It is usually due to a lack of nitrogen fertilizer, or the sun shines for too long.

Excessive water The manifestation of excessive watering is that the young leaves are dark yellow and dull, the old leaves have no obvious changes, the branches are small yellow-green, and the new shoots are shrunk and not long. The flowers should be depotted and placed in a ventilated and cool place to dry the soil before putting them back into the pot.

Too little water The yellow of the lack of water is the withering and dry leaf tips or edges, and the old leaves are withered and yellow from the bottom to the top, but the growth of new leaves is relatively normal. Pay attention to watering when watering enough, water thoroughly.

The sunlight is too strong and the strong sunlight directly hits some shade-loving flowers, such as spider plants, hostas, etc., which is easy to cause the leaf tips and leaf margins of flowers to wither, and the sunny part of the leaves to appear yellow spots. Move the plant to the shade.

Insufficient light If the shade environment is placed for a long time, the leaves do not get enough sunlight to form chlorophyll, and the whole leaves turn yellow and then fall off. Move the potted plant to a sunny environment and add light.

Excessive fertilization Excessive fertilization or excessive concentration of flowers caused by yellowing is manifested in the appearance of dry brown at the top of the new leaves, and the general leaf surface is thick and dull, and the concave and convex are not stretched, and the old leaves are scorched and yellow. Fertilization should be stopped immediately, and part of the fertilizer should be washed with plenty of washing in severe cases.

Lack of fertilizer and yellowing The young leaves become lighter in color, yellow or light green, while the old leaves are more normal or gradually turn from green to yellow, which indicates a lack of fertilizer. Check that if the potting soil is dry, the soil should be replaced, and the thin fertilizer should be applied diligently and some alum water should be poured in a timely manner.
