The rich tree is supposed to be raised like this in winter. No wonder I always have yellow leaves.

The rich tree means to get rich, and it is also very good for decoration, so it is very popular with everyone, but many flower friends report that the rich tree is not easy to raise, its leaves turn yellow and lose its leaves easily, and the rich tree has never survived the winter. in fact, the rich tree cannot survive the winter because it has not done a good job in winter conservation:

1. The temperature is too low and frozen. It is the cold winter season. If you accidentally put the rich tree where the cold wind can blow, or the cold air is too low, then it will not take long for you to find that the leaves of the rich tree begin to scorch and fall off. Solution: keep the indoor temperature no less than 8 ℃. If the temperature is too low, consider using a plastic bag to keep it warm. Don't put the rich tree where it can blow to the cold wind. 2. Too much watering leads to the loss of yellow leaves and the cold weather in winter. If you pour too much water on the rich tree, the basin soil will be too wet for a long time, it will cause lack of oxygen in the soil, and the beard root will rot, which will hinder the normal breathing of the rich tree and the absorption of nutrients, thus causing the leaves to turn yellow and fall off.

Solution: to reduce the frequency of watering the rich tree in winter, once a month is enough. 3. The air is too dry in winter, especially when there is heating in the north, the excessive dryness of the air will lead to scorch and yellowing of the leaves of the rich trees. Solution: usually spray more water on the leaves of the rich tree to increase the humidity of the air.

4. Diseases and insect pests are relatively cold in winter, so most of the time the doors and windows are closed and the ventilation is very poor. if the rich tree grows in such an environment for a long time, it is easy to breed red spiders and shell insects, resulting in yellowing leaves. Solution: although it is cold in winter, you can choose to open the window for 2 to 3 hours when the temperature is high at noon, which is not only good for plants, but also conducive to the health of your family.

How to raise a rich tree in winter? What if the leaves of the rich tree turn yellow?

The main reasons for the loss of potted rich trees are as follows:

1. The ambient temperature is low. If the indoor ambient temperature of your rich tree is maintained above 15 degrees Celsius and the temperature is below 18 degrees Celsius, the tree stops growing. The tree is native to tropical America and widely distributed in Southeast Asia. It is required to grow at an appropriate temperature of 18-30 degrees Celsius, not cold-resistant, and leave the room at the end of March or early May of the lunar calendar in spring. Avoid room temperature below 8 degrees Celsius, otherwise frost injury will occur. Those who are light fall their leaves, and those who are heavy die.

two。 There is not enough light. Wealth trees like the light but avoid direct sunlight, and keep it indoors where there is scattered light, while it is better to put it indoors in winter. Starting from late April, choose a sunny and warm noon, move the basin out of the outdoor or balcony, directly see the sun for 1-2 hours, and gradually extend the time until full light management. in the outdoor full light environment, the leaf node is short, the leaf is wide, the color is dark green, the crown is plump, and the base of the stem is fat. In low light for a long time, the branches are thin, the petiole is drooping, and the leaves are light green. No matter under what environment, do not suddenly change the location, change the location should be gradually adapted to the process, such as suddenly moving the plant from the shade to the sun, will make the leaves burn, scorched edge, affect the appearance. Long-term lack of light, the plant is easy to appear yellow leaves and accompanied by shedding.

3. The moisture is too wet. Rich trees do not have high requirements for water and should not be watered too much to prevent stagnant water in the basin soil, causing root rot and plant death. The indoor water is watered once in summer and 5-10 days in spring and autumn, but it is not an absolute interval, so it should be grasped flexibly, and the principle of "dry and wet" should be taken as the principle. If the water is too wet, there will be waterlogging, yellow leaves, root rot and shedding.

4. There is too much fertilizer. If the plant grows rapidly in the period of suitable temperature, regular fertilization should be applied regularly to ensure the luxuriant growth of the plant, and the second thin fertilizer should be applied in about 20 days, but less nitrogen fertilizer should be applied to avoid overgrowth. When changing the basin, we should not only replace the new nutrient soil, but also add rotten base fertilizer to make it thrive. If too much fertilizer is applied, or if the fertilizer is not rotten, the roots will burn, yellow leaves will occur and fall off.

5. The leaves are covered with thick dust. The leaf surface such as dust is too thick, which not only affects the appearance, but also affects the respiration and photosynthesis of the plant. Seriously affect the healthy growth of the plant, the dust on the leaf surface should be sprayed clean in time, or wipe clean with a soft cloth. What if the leaves of the rich tree turn yellow?

The first reason for the yellowing of the leaves of the rich tree: improper watering

Rich trees like warm and humid climates. too much or too little watering will cause the leaves to turn yellow.

Too much watering, the soil in the basin is often kept too wet, the roots of the rich tree can not breathe smoothly, the roots rot, and then gradually spread to the branches, and finally the leaves turn yellow, wither and fall off, and in serious cases the whole plant dies. Too little watering, wet above the basin soil and dry below, will not only affect the absorption of nutrients, but also cause the leaves to be dull, and gradually wither and fall off from the bottom to the top. The rich tree makes a silent protest against your laziness.

Solution: timely ventilation, basin turning or water replenishment.

When watering too much, put it by the window to make it ventilated and loosen the soil. If the basin soil cannot be dried in a short time and is silt-like, you can pad a layer of absorbent cotton cloth on the bottom of the flowerpot and replace it with a new one when wet through, or blow it with a fan breeze. If the soil does not dry out by all means, then change it.

When watering too little, the soil surface cracks, in the case of not all yellowing, gradually replenish water. First wet the soil surface, water a little for an hour, and gradually water through. Avoid one-time watering, lest the root absorb water and expand, affecting the growth.

Reason 2: improper lighting

Rich trees like sunlight, but they are not resistant to direct sunlight, and hot sun exposure or long-term shade can also cause withered and yellow leaves.

Put the wealth tree in the corner of the indoor wall, pay too much attention to the ornamental effect, so that the wealth tree has been in a shady environment for a long time, which will lead to the growth of new branches and leaves, dull old leaves and a large number of shedding. Summer is hot, you can only blow air-conditioning in the house, how can the rich tree withstand the impact of the scorching sun. If you forget to move it to a shady place at noon, you can only accept the yellowing of the leaves.

Solution: move to the semi-shade.

For the case of sudden exposure to sunlight, which leads to the yellowing of the leaves of the rich tree, there is little chance of saving. The leaves are yellowed due to excessive exposure, and the water volatilization of the leaves is serious, which is difficult to recover in a short time, so it is recommended to move to a semi-shady place. Properly watered, the yellowed leaves will slowly fall off, waiting for new buds to grow.

Reason 3: too much fertilizer

If you are in a hurry, you must be afraid that the rich tree will become malnourished due to lack of fertilizer. But not even excessive fertilization. The nutrient absorbed by the rich tree is quantitative, if the fertilizer is too much, the plant absorbs enough nutrients, the remaining fertilizer will burn the roots of the rich tree, resulting in yellowing leaves.

Solution: pruning and changing soil.

Excessive fertilization causes the roots of the rich tree to rot, remove the plant from the pot, clean up the rotten part, replace it with new soil, and replant it. Or through watering, dilute the nutrients in the soil, reduce fertility.

Reason 4: temperature discomfort

Some people hate summer and winter because one temperature is too high and the other is too low. In fact, the same is true of plants. The suitable temperature for rich trees to grow is 20 ℃ ~ 30 ℃. Too high or too low will affect their growth.

If the temperature in the growing environment of the rich tree is too high, the transpiration is too strong, and the water and nutrients in the roots are insufficient, the leaves will gradually dry up and turn yellow. But if the temperature is too low, for example, the winter temperature is lower than 16 ℃, the leaves are easy to yellowing and falling off, and the leaves below 10 ℃ are easy to die.

Solution: warming.

In summer, because the temperature is too high to cause the rich tree yellow leaves, move the plant to a shady place in time, sprinkle water to cool down, if the yellowing is not serious, it will slowly resume growth. In winter, raise the maintenance temperature appropriately to avoid plant frostbite.

Reason 5: diseases and insect pests

The rich tree is attacked by fungi and bacteria, which leads to leaf spot disease, local necrosis of the leaves, yellow patches or spots, and in serious cases, the whole piece is withered and fallen.

There are not only germs coveting the rich tree, but also many pests such as red spiders and shell insects, which will also cause the withered and yellow leaves of the rich tree, so observe carefully.

Solution: spray chemicals.

Strengthen ventilation and spray chemicals in time. According to different diseases and insect pests, choose the corresponding fungicides, spray once every 5-7 days, spray 3-4 times basically meet. (recommended medicament: carbendazim, chlorothalonil, Huasen)

Reason 6: the branches and leaves are too dense

The growth ability of the rich tree is relatively strong, so the branches and leaves grow vigorously, if you do not have the habit of regular pruning, then the branches and leaves hidden at the bottom will turn yellow and droop because of lack of light and lack of ventilation.

Solution: pruning in time.

The wealth trees in many flower friends' homes have grown into straw hats and are not pruned. As a kind of foliage plant, it is important to have luxuriant branches and leaves. But it is your fault that there are too many leaves that hinder the growth of the plant.

The rich tree grows faster, for the potted plants with luxuriant branches and leaves, you can prune part of the branches, do not have to give up, they will soon grow new buds, and the plants will grow more luxuriantly.

If you can't bear it, let's take a look at how the flower friends prune the rich tree. →→ "diagram" the pruning method of the rich tree.

Reason 7: soil is alkaline.

Soil is an indispensable factor for the growth of wealth trees. in most parts of the north, the soil contains more saline and alkali, but the wealth tree likes acidity, and it is a big deal if the soil is not satisfied with water and soil. the result of malnutrition is that the leaves are withered and yellow.

Solution: acidify the soil.

Rich trees are suitable for growing in acidic soil, and yellowing rich trees can be remedied by changing the acidity and basicity of the soil in time. Do not need to take off the basin, do not need to change the soil, just apply a certain amount of ferrous sulfate to the soil and sprinkle it directly in the flowerpot, which can not only increase the soil fertility, but also acidify the soil, killing two birds with one stone.

Be careful not to use vinegar in the process of acidifying the soil. It is true that vinegar can quickly make the soil sour, but because the change is radical, it will damage the organic matter in the soil and reduce the soil fertility.

How to prevent the leaves of rich trees from yellowing and control the amount of water

In order not to let you cry because the leaves of the rich tree are yellowing, we have to do everything before it turns yellow, starting with watering. Watering the rich tree should follow the principle of "no dry, no watering, watering thoroughly". It can be watered once every 15 to 20 days under normal maintenance.

What? You said that the explanation of the editor is too rough, which I can not bear, the editor, I want to put on a big move, to recommend to you the professional knowledge of the flower grower to water the wealth tree →→, "the talent said," how to water the wealth tree, don't thank me too much.

Reasonable illumination

To maintain the wealth tree, you have to do your best every day. Starting from late April, choose a sunny and warm noon, move it outside or on the balcony, and receive sunlight for 1-2 hours at first, and then gradually extend the time. You will get unexpected results.

Of course, it is best to spend the summer in the morning or evening, when the sun is relatively mild and will not cause harm to the wealth tree.

Moderate fertilization

To fertilize the rich tree, we should follow the principle of "applying thin fertilizer frequently", apply fertilizer according to the growth of the plant, apply liquid fertilizer or mixed flower fertilizer every 1 to 2 weeks, and add rotten base fertilizer in time when changing pots.

Control the pH of the soil

In fact, most of the soil in the family is bought directly from the market, and the soil in the basin is acidic. But why is there still the phenomenon of yellow leaves? This is related to our watering and soil exchange, when watering, try to choose acidic water (Rain Water, river water, tap water after placement); in addition, ferrous sulfate solution can be irrigated at ordinary times to ensure that the acidity and alkalinity of the soil is in a suitable range.

Clean the branches and leaves regularly

First, it is necessary to prune in time, cutting off overdense, overgrown and diseased branches to enhance the light transmittance of the plant. Second, to clean up the dust on the leaf surface, too much dust on the leaf surface will not only affect the appearance, but also reduce photosynthesis and lead to leaf yellowing.

Timely control of diseases and insect pests

When raising rich trees indoors, because of ventilation, light and humidity, diseases and insect pests are unavoidable. The key point is to take preventive measures. In addition to cloudy, rainy days and winter, it is necessary to ensure that the air in the maintenance environment is smooth; in the hot and redundant season, spray fungicides once each to take precautions.

Keep the right temperature

The rich tree is sensitive to temperature, yellowing when it is hot and yellowing when it is cold, so the appropriate temperature is very important. The suitable growth temperature of rich tree is 22-35 ℃, which is higher than 35 ℃, and the growth slows down. The lowest temperature in winter is 16-18 ℃ (basically the same as the indoor temperature). Below this temperature, the leaves turn yellow and fall off, and the plants below 10 ℃ are easy to die.
