Is the whitening of the leaves of the peace tree the cause?

The leaves of the peace tree turn white because the red spider absorbs chlorophyll, so it is necessary to spray dicofol and other acaricidal pesticides, and at the same time spray potassium dihydrogen phosphate or a spray of chlorine, and the leaves turn green after ten days.

This is a scale insect infestation, and the scale insect part can be wiped with alcohol or white vinegar. Cut off the yellowed leaves. Scale insect control:

1. If you find that there are scale insects on individual branches or leaves, gently brush them off with a soft brush, or combine them with pruning to cut off the insect branches and leaves. It is required to be brushed, cut, and burned in a centralized manner, and do not litter.

2. Mix liquor with water, the ratio is 1:2. When treating insects, water the surface layer of the potting soil thoroughly. Scale insects begin to move at room temperature 7 in spring. It can be watered once in mid-April, and then every half a month or so, and it is effective for 4 consecutive times.

3. Use 50 ml of vinegar or rice vinegar to soak the small cotton ball in vinegar, and gently wipe it on the stems and leaves of the damaged flowers and trees with a wet cotton ball, and the scale insects can be wiped off and killed. This method is convenient and safe, which can not only achieve the purpose of insect control, but also make the damaged leaves green and shiny again.

4. Gently and repeatedly wipe the diseased plant with alcohol to get rid of the scale insects, and it can be removed very cleanly and thoroughly. If you wipe the orchid leaves with alcohol, not only can the scale insects be removed, but also the larvae that are not clear to the naked eye, they are also completely killed, and the second year is rarely found to be harmful to the proprietary scale insects, this method is simple, safe, and the effect is good.

The leaves of the peace tree are yellow, and there are a few points to solve, which can be easily done.

The environment in which you raise a peace tree is too unventilated. Powdery mildew caused by over-watering and insufficient light.

First, the treatment method.

Once the leaves of the tree are found to be yellow, the yellowed leaves should be cut off immediately. Even if they are not cut, stupid potatoes will consume nutrients and affect their ornamental value. If the condition is severe, it is necessary to remove the pot and check the condition of the root system to see if there are any rotten roots.

If the cover is removed, it should be cleaned immediately and replanted. Note that it is better to replace the previous soil, as some germs will remain in the soil. If this plant is planted directly, it is likely that root rot will occur again.

2. Change the maintenance method.

1. Less watering: Usually a small amount of watering. Remember that there can be no water in the potting soil, and the amount of watering should be properly controlled.

In addition, on rainy days, it is necessary to take measures to take shelter from the rain. 2.Blocking glare:

It should not be left in the sun in the summer. Let it grow indoors or in a shady place, such as the shade. Spray as much water as you can to replenish the hydration it needs.

Summary. Proper water control: water accumulation causes yellowing of leaves, so it is necessary to loosen the soil and drain it in time, and water it after the soil is dry in the later management.

Supplemental light: Lack of light leads to a decrease in chlorophyll, so move the peace tree into a place of astigmatism to receive light. Soil change fertilization:

The poor soil affects the growth of the root system, so it is necessary to replace the fertile and loose soil for the safe tree and replant it.

Proper water control: water accumulation causes the leaves of the mountain to turn yellow, so it is necessary to loosen the soil and drain it in time, and water it after the soil is dry in the later management. Supplemental Lighting:

Lack of light leads to a decrease in chlorophyll, so the peace tree should be moved into the astigmatism to receive light filial piety line irradiation. Soil change and fertilization: The poor soil affects the growth of the root system, so it is necessary to replace the fertile and loose soil for the safe tree and replant.

What should I do if the leaves of the peace tree are dry?

There are many reasons for the dry leaves of the peace tree, if it is just changed or the environment has changed, the plant has not adapted to the cause, you can maintain it slowly. If it is caused by the alkalinity of the substrate, it is necessary to replace it with weakly acidic flower soil. If it is caused by too cold in winter, you need to keep warm in time.

If it is caused by rotten roots, you need to prune the root system and repot it.

The reason why the leaves of the peace tree are yellow and falling.

1. Improper watering.

When we are watering the peace tree, if the amount of water is not in place or too much watering leads to its water accumulation, it will make the leaves of the peace tree yellow or fall, because the weather is too hot in summer, the water of the peace tree will evaporate, if the watering is not in place, it will lead to a serious lack of water, so that the leaves are yellow. Excessive watering will make it impossible for the tree to absorb all the water, resulting in water accumulation in the roots, and the roots of the tree will be damaged or rot.

2. Improper fertilization.

When fertilizing the peace tree, too much or too much fertilizer will make the leaves of the peace tree become fat and uneven, and too little fertilizer will cause the peace tree to absorb nutrients, and the leaves of the peace tree will turn yellow for a long time. It is recommended to supplement nutrients with diluted water-soluble fertilizer during the growth period, but the dosage is not too much.

3. The temperature is uncomfortable.

At the same time, when the light is strong in summer, it will cause the leaves of the peace tree to turn yellow, and when the temperature is too low in winter, it will cause its leaves to turn yellow, if the temperature is lower than 5 degrees, the peace tree will be frostbitten, and the leaves will be yellowing and falling off.

4. Alkaline water should not be used.

When watering the peace tree, we should pay attention to the acidity and alkalinity of the water, and we should apply more organic fertilizer to it at ordinary times, if you water it with alkaline water for a long time, its leaves will slowly turn yellow, and even fall off.

The dry leaves of the peace tree may be due to the following reasons.

1. The soil of the potting soil of Ping'an tree is alkaline.

The peace tree likes to grow in the acidic sandy loam soil with loose and fertile and good drainage performance, but because the potting soil is cultivated for too long, especially when watering, it will reduce the acidity in the soil, which will lead to the drying out of the leaves of the peace tree.

2. The peace tree is overwatered.

There is also a big reason for the dry leaves of the peace tree may be too much watering, if the water seepage speed of the pot is not very good, too much watering will be easy to appear waterlogged, if the temperature is high at this time, it will cause the roots of the peace tree to rot, in the early stage there will be no luster and a little yellow, the leaves will dry up and grow spots after a long time, if not in time, it will die.

3. The leaves of the peace tree are dried up due to disease.

If there is a branch blight disease in the peace tree, it will lead to the drying of the leaves, which is mainly caused by the lack of ventilation during maintenance, which is also easy to infect other leaves, and in serious cases, it will lead to a large area of branches and leaves, and if treated, it will easily cause the death of the tree.

A flower friend asked: I bought a pot of peace trees a month ago, and the branches were full of foliage at that time. Yellow leaves appear in a few days, and then the leaves fall off, and the roots are not dead, how can you make it recover?

Regarding the above question, Uncle Gardener will tell you what is the reason for the yellowing of the leaves of the peace tree and what to do if the leaves of the peace tree are yellow?

In the process of indoor flower breeding, the yellowing of leaves is a more common phenomenon, and the same is true for the safe tree in indoor breeding, it is inevitable that the leaves will be yellowed.

Analysis of the causes of yellowing of leaves of Ping An tree and specific solutions for different causes.

Reason 1: Water yellowing, caused by excessive watering, is characterized by no obvious changes in the old leaves and yellowing of the young leaves.

Solution: Control watering immediately.

Reason 2: Drought yellow, caused by lack of water and drought, is characterized by the first yellow of old leaves from the bottom up.

Solution: Watering in time, otherwise due to the lack of water for a long time, the whole plant will have yellow leaves, and even die.

Reason 3: Fat yellow, caused by too frequent fertilization or too high concentration, is characterized by thick young leaves, shiny, and uneven.

Solution: fertilizer control, cultivating, and watering.

Reason 4: Hungry yellow, caused by insufficient fertilizer, low fertilizer concentration, and long fertilization interval, it is characterized by young leaves and young stems.

Solution: Timely fertilization, if you do not fertilize in time after seeing this phenomenon, it will cause the whole plant yellow leaves or even die, do not apply a large amount of thick fertilizer at a time.

Reason 5: Iron deficiency yellow leaves are coarse, woody flowers in greenhouses, etc., due to the great change of soil fertility conditions, the phenomenon of yellow leaves often appears, which is characterized by obvious young leaves, light old leaves, yellow mesophyll, green leaf veins, and the formation of a typical network.

Solution: Ferrous sulfate aqueous solution can be applied to solve the problem, the method is: 7 parts of cake fertilizer, 5 parts of ferrous sulfate, 200 parts of water are poured into multiple liquids.

Reason 6: It is caused by long-term exposure to the scorching sun, which causes the leaves to dry and yellow.

Solution: Immediately move to a 40% to 50% darkened environment for maintenance.

In short, it is necessary to focus on the specific causes and prescribe medicine for blindness, and it is absolutely impossible to treat it indiscriminately without analysis.

Raise flowers, go to the florist forum:, sing all the way, laugh all the way, it's really lively on the road to raise flowers!

It prefers warm, humid and sunny environments, likes light and shade, likes warm and hot, frost-free snow, foggy and high-temperature places, and is not tolerant to drought, stagnant water, severe cold and dry air. It is advisable to use a loose, fertile, well-drained, acidic sandy soil rich in organic matter. In its native environment, phalaenopsis is abundant, so under artificial cultivation conditions, it is advisable to create a warm and humid environment for it.

It may be related to light and water, and then it may be brown spot disease occurs on the new leaves of the plant from April to May, and oval yellow-brown spots begin to appear on the leaf surface, and then expand, and there are more small black dots in the front of the leaves, and the back of the lesions is purple, so that the whole leaf yellows and withers, so that the plant loses a large number of leaves. Prevention and control methods: 1% Bordeaux solution can be used for prevention; If a small number of diseased leaves appear, remove and burn them in time; At the beginning of the disease, 500 times of 50% carbendazim wettable powder, or 1000 times of 50% benmonazim wettable powder, alternately sprayed every 10 days or so, 3 to 4 times in a row.
