Why do the flowers raised at home turn yellow? What is the reason for the yellowing of the leaves of

Why do the flowers raised at home often turn yellow? One reason could be because the pot is not changed very often. The lack of nutrients in the soil can cause the roots and leaves to turn yellow.

In one case, it may be because the soil is too wet due to frequent watering in the pots at home, so it will turn yellow.

Potted flowers due to the root in the pot is free to restrict, can not be free to stretch around, the development of the root system is hindered, the ability to absorb water and nutrients declines, if in watering, fertilization and other aspects of improper management, it will make the root system hypoxic, block its ability to absorb, and then there will be yellow leaves or even rotten roots to die. Here are the causes of these causes and solutions.

The salinity content of soil and water is too large. Especially in the northern region, the cultivation of acid-loving flowers, such as rhododendrons, gardenias, camellias, osmanthus, etc., due to the lack of iron and other elements in the soil, the leaves will gradually turn yellow. Therefore, acidic soil should be used for transplanting, and alum fertilizer should be watered frequently during the growth period.

The temperature is not suitable. In winter, the temperature is low, and most warm-loving flowers are often susceptible to cold damage, which leads to yellowing of leaves, and in severe cases, yellowing and death. If the temperature is too high, the nutrients and water in the roots cannot meet the growth of the branches and leaves, and the leaves will turn yellow.

The temperature should be adjusted in time to meet the needs of flower growth. Too much watering, too much water in the soil, resulting in insufficient oxygen in the soil, poor aeration, partial rot of the root system, causing the leaves to turn yellow and fall off. At this time, it is necessary to control watering and fertilization, immediately loosen the soil, make the soil aerated well, and replace the soil in serious cases.

The potting soil is too dry. Flowers sometimes forget to water or are not watered at all, and the roots cannot absorb water, causing the leaves to wilt and droop. Gradually withered and yellowed and fell off.

At this time, the leaves should be sprayed with water first, and then a small amount of water should be poured in, and then managed normally after the recovery state. Excessive fertilization is too strong. Excessive and too concentrated fertilization will cause the leaves to yellow and fall off, at this time, the amount of watering should be increased, so that the fertilizer flows out of the drainage hole at the bottom of the pot, or immediately pour the pot, rinse the soil with water and then replant it into the pot.

If the pot and soil are not changed for a long time, the flower roots cannot grow, the nutrients in the soil are lacking, and the potting soil is compacted, resulting in thin plants and thin, small and yellow leaves. This requires timely repotting and soil change, and the introduction of new loose and fertile humus and organic fertilizer.

Poor ventilation. Especially in the summer high temperature weather, coupled with the growth of branches and leaves, coupled with the long-term lack of pruning, the inside of the branches and leaves is impermeable, and the photosynthesis is not strong, which is easy to cause the leaves to yellow and fall off. Pruning should be intensified, and some overly dense branches should be cut off to ventilate and transmit light.

The branches and leaves caused by pests and diseases are yellow, leaf spots appear, and when the whole leaf is yellowed and falls off, the leaves that suffer from insect pests will also become local yellow wilt, and even the whole leaf will turn yellow and fall off. Prevention and prevention should be carried out in a timely manner, and rational use of drugs should be achieved.

Summary. Of course! Goldenrod is a great plant to keep at home.

It doesn't need much sunlight and just needs the right amount of light to grow lush. Moreover, the growth rate of yellow flowers is relatively fast, so you can enjoy the process of their beautiful flowers opening at home. It should be noted that goldenrod is sensitive to moist soil, so it is necessary to control the frequency and amount of watering to avoid overwatering.

You've done a great job! Can you elaborate on that?

Goldenrod is a plant that is suitable for keeping at home. It prefers moderate light and grows quickly. Care should be taken to control the frequency and amount of watering and apply fertilizer regularly. In short, as long as there is a proper environment and care, it can grow up at home hungry or in the middle of a long time.

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.

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.

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

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.

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.
