What is the reason for the yellowing of the leaves of potted flowers?

In general, the color of the top leaves of potted flowers is normal, but the lower leaves gradually dry up and fall off. This is usually due to the fact that the potting soil cannot be watered for a long time, causing the lower leaves to age and turn yellow. Watering should be increased appropriately to keep the soil moist.

If the potting soil is too wet, the young leaves are pale yellow from the top of the flowers, and the old leaves are gradually yellow, and the new shoots are shriveled.

Compared with your flowers, it seems that the pot soil is too dry and yellow, it is recommended to water it thoroughly, not only use a sponge to soak in the water, so that the surface is wet, the soil is not wet inside, the old flower farmer originally grew moss outside the pot, and the water was caused by the penetration of the inside and outside, that is, after the water was sufficient.

Frequent watering of flowers and plants, once the potting soil is too wet for a long time, the communication between the soil and the air is not smooth, it will cause a lack of oxygen in the soil, so that the roots of flowers and plants appear rotten roots, so it will cause the leaves to turn yellow and fall off. If you find that the flowers and leaves are yellow due to too much watering, you need to water sparingly, and let the potting soil ventilate in time to promote water evaporation.

If the leaves of potted flowers are yellow, generally speaking, it depends on whether there is a lack of water, and some are caused by a lack of fertilizer.

The roots are big and the soil is less, and the pots are not enough, cut some old roots, change to a large pot, get some good soil, add some organic fertilizer or nutrient soil, replant it, and water it well.

There is no normal lighting.

You're watering too diligently.

Haven't watered for a long time.

You loosen the soil for him, see if the soil is dry or wet, and if it is dry, water it thoroughly (water seeps out from the bottom)!If it's wet, put it on the windowsill and give it proper light! When the potting soil is dry, get some rice water and pour it.

In general, there are several reasons for the yellowing and falling of flower and grass leaves.

1. Water yellow. Excessive water and stagnant water in the potting soil will lead to root lesions and rot of the plant, and the symptoms are that the new young leaves are dark and dull, and the new shoots are atrophied.

Solution: control the water and loosen the soil in time to let the water evaporate as soon as possible.

2. Dry yellow. Contrary to water yellowing, it refers to the phenomenon of yellowing of plant leaves caused by lack of water caused by improper watering for a long time. For example, if the potting soil is too full and cannot be watered thoroughly, it is manifested that the color of the new leaves is normal, but the old leaves start to dry up and fall off from the roots.

Solution: Take out too much potting soil and water it thoroughly, or use the soaking method to let the potting soil absorb the water.

3. Fat yellow. Excessive fertilization makes the new leaves appear thick and unstretched, and the old leaves turn yellow and fall off.

Solution: Stop fertilizing, water frequently, or sprinkle some leafy vegetable seeds in the pot and pull them out when they germinate and grow to a certain height, so as to consume too much fertilizer.

4. Lack of fat yellow.

Long-term failure to change the potting soil, insufficient fertilization, or too small potting caused by the yellowing of leaves.

Solution: Apply fertilizer and water in time according to the needs of plant growth, change the pot and soil once in one or two years, and apply sufficient base fertilizer when changing the pot. There are many other reasons for the yellowing of potted leaves, and I will continue to introduce them in future articles, so please continue.

As long as we have the patience to find the right cause, we can solve the problem by prescribing the right medicine, and we can make the potted flowers grow healthily.

If you find that the leaves of potted plants are yellow, you should first take pruning measures to avoid the loss of excess nutrients. Prune yellow leaves, dead leaves, diseased branches, cross branches, and long branches. Then find the cause of yellow leaves, and you need targeted treatment.

If the watering is improper, there is a shortage of water or there is a lot of water, the watering method should be adjusted in time. If there is a shortage of water, replenish the appropriate amount of water, and drain it as soon as possible if there is stagnant water. If the soil is compacted, it is better to change the soil of the plants, and it is better to loosen the loam soil rich in organic matter.

If the light is too strong and burns the leaves, it is necessary to shade the light in time and ventilate more. If it is caused by low temperature, move to a warm environment and ensure that the temperature is above 10. If it is caused by a lack of nutrients, it is necessary to supplement fertilizer in time, and apply thin fertilizer frequently to ensure that the nutrients are sufficient.

If the thick fertilizer burns the roots, it should be washed with large water to dilute the fertilizer solution.

It is very common for potted plants to have yellow leaves, so it is necessary to find the cause of yellow leaves according to the symptoms and deal with it in time. Let's talk about the solution in detail.

Watering is an important part of the maintenance and management process of potted plants.

Most potted plants have yellow leaves, which are caused by improper watering, and the potting soil is too dry for a long time, or the water is large and siltation may cause the leaves to turn yellow.

The amount of water required for potted plants should be flexibly adjusted according to seasonal temperature and other conditions. It should be insisted on not drying or watering, drying and watering thoroughly, so that the potting soil can be dry and wet. If there are yellow leaves caused by too much watering, at the beginning, depot it in time, dry the roots in a cool and ventilated place, prune off the rotten roots and yellow leaves, sterilize and disinfect the roots, and then change the soil again.

Potting soil siltation or compaction should be replaced in time, and loose is preferred.

Soil siltation or compaction causes the potted leaves to turn yellow, and the potting soil needs to be replaced in time. Generally speaking, we can change the soil every 2 years. It is recommended to use loose vegetable garden soil or peat soil, humus soil, coarse sand, and organic fertilizer in the ratio of 5:3:1:1.

Diffused light, comfortable environment.

Everything grows by the sun, potted plants like to grow in scattered light, exposure to the sun or strong light will cause the leaves to wither, affecting the aesthetics. Ordinary potted plants prefer a cool, moist diffused light environment. Place the bonsai in a warm and sunny location every day.

Sprinkle water around the potted plants often to keep the air humidity high, and soon the plants will be able to grow new branches and leaves.

1.The yellowing caused by excessive watering, this kind of first the young leaves turn yellow, and then the old leaves turn yellow, reduce watering.

2.The yellowing of the leaves caused by too little watering is the yellowing of the old leaves, just increase the watering.

3.Yellowing caused by a bacterial infection, which has spots on the leaves, requires spraying with chlorothalonil solution.

4.If it is caused by poor ventilation, move to a well-ventilated place and a bright place.

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

There are several main types of causes of yellowing of the leaves of potted flowers:

1) Yellow leaves caused by excessive watering are manifested in the dark yellow and dull young leaves, but there is no obvious change in the old leaves, the branches and stems are small and yellow-green, and the new shoots are shrunk and not long.

2) Due to the long-term lack of watering, or less watering, the leaves are yellow, and the old leaves fall off from the bottom up, but the new leaves generally grow normally.

3) Potted flowers that like yellow and dampness, such as spider plant, evergreen, hosta, etc., if exposed to strong direct light, the leaves will appear scorched at the top or edge.

4) Alkali yellowSome acidic soil flowers and trees, such as gardenia, camellia, rhododendron, jasmine, etc., such as potting soil or water quality is alkaline, the leaves turn from green to yellow, and even fall off.

5) Fat yellow due to more fertilization or excessive concentration, the top of the new leaves appear dry brown, although the general leaf surface is thick and shiny, but most of them are uneven and unstretched, and the old leaves are dry and yellow and fall off.

6) Damp heat yellowSome potted flowers that are not resistant to high temperature and high humidity cause yellow leaves due to poor ventilation and improper shading in midsummer. For example, the hanging bell begonia has this phenomenon in summer.

7) Lack of fertilizer yellow potted flowers only watering for a long time without fertilization, or do not change the pot for many years, the roots are rolling, the top dressing is easy to leak, and the plant can not get fertilizer, resulting in yellowing of the leaves.

Potted flowers are harmed by diseases and insects or encounter sudden cold and heat, which can also cause yellow leaves to fall off. If only a few leaves are yellowed and fall off on the lower branches of the plant, this is a normal phenomenon of leaf maturity and aging.

1. Control watering: After entering the room, because the space is not as open as the outdoors, the water transpiration on the surface of the pot and the plant is reduced. If you continue to water as before, the potting soil will be wet and the roots will rot, and the leaves on the ground part of the plant will turn yellow.

2. Reduce fertilization: In autumn, most flowers turn from vigorous growth to slow growth, and after the flowers enter the house, they will enter the stage of rapid growth due to the rising temperature. However, the absorption of fertilizer is not as good as in summer, so it is necessary to reduce or stop topdressing to prevent the plants from turning yellow leaves.

3. Adjust the light: Some flowers that like strong light, such as Yueji, Fusang, etc., if they are placed in a shady place after entering the house, due to insufficient light, the plants will have yellow leaves. On the contrary, placing shade-loving bird's nest ferns and monstera in places with too much sunlight will also cause the leaves to lose green and yellow.

The location of the flowers in the room should also be adjusted reasonably.

4. Environmental ventilation: the environmental canopy will gradually increase the content of ethylene, the gas that causes flower senescence, in the air. Therefore, keeping good ventilation is one of the effective measures to prevent yellow leaves of indoor flowers.

5. Maintain the right temperature: Due to the uncomfortable ambient temperature, many flowers will also have yellow leaves, especially in the case of a large temperature difference between flowers before and after entering the room. For example, if you move Milan and azaleas to a greenhouse at a minimum outdoor temperature of around 5, and the ambient temperature rises to about 25 during the day due to inattention to cooling, the plants will soon have yellow leaves, and this should also be prevented.
