What s going on with the tips of the leaves of pine saplings turning red, and what causes the rednes

Which is the blight? Root irrigation with streptomycin sulfate (human medicine) will do. General pesticides do not work.

What should I do if the leaves of a pine tree turn yellow? Many people don't know what to do, but what to do? Let's explain it in detail, I believe you will know what to do after reading it.

1. Prune off the yellow leaves.

First of all, if the leaves of the pine tree are yellow, we must first prune off the yellowing leaves, which is the first thing to do, because if it is not pruned, then it will actually affect the growth of the pine tree, which we need to know.

2. Properly loosen the soil.

After that, we need to loosen the soil properly, because if the soil is too compact, then the pine tree will absorb less water and nutrients, which will cause the pine tree to appear yellowing of the leaves, which we need to pay attention to.

3. Reasonable watering.

We also need to water properly, because if we water too little, it will also cause the pine leaves to turn yellow, we need to pay special attention to this, generally we had better water every 2 days, so that the pine leaves will no longer turn yellow.

4. Reasonable fertilization.

We also need to fertilize properly, if the soil is too poor, and we don't do any fertilization measures, it will also cause the pine leaves to turn yellow, we need to apply fertilization microbial agents to improve this problem.

5. Temperature control.

If the temperature is too high or too low, it will also cause the pine leaves to turn yellow, so we need to deal with it in time to make the pine leaves no longer yellow, especially when the temperature is too high, we can sprinkle water appropriately to cool down.

6. Humidity control.

If the humidity is too low, it will also cause the pine leaves to turn yellow, when the humidity is too low, we can sprinkle water in the air to increase the humidity, and sprinkle water around the pine tree to increase the humidity, which we need to know.

AbstractThe redness of pine leaves is likely to be caused by pine needle rust, mainly because the soil in which pine trees grow is too compact and not breathable, so it will cause the leaves of pine trees to turn red.

What causes the redness of pine leaves.

The redness of the pine leaves is most likely due to pine needle rust, mainly because the soil in which the pine tree grows is too compact and not breathable, so it will cause the pine leaves to turn red.

It is necessary to give Pinus tabuliformis drug control, you can use Bordeaux liquid with water, or with stone sulfur mixture with water 1000 times, and then spray Pinus tabuliformis every 15 days, a total of about three sprays, so that it can effectively ** the phenomenon of redness of Pinus tabuliformis leaves.

Summary. Hello, the yellow leaves of Korean pine are due to the lack of iron in the wild Iron is an element that pine trees cannot do without growth. If there is a lack of iron, the leaves are prone to yellowing, and poor growth will occur.

To spray fertilizer to the foliar surface as soon as possible, you can choose ferrous sulfate fertilizer, ammonium ferrous sulfate, spray a few more times and it will soon recover. Temperature discomfort In early spring, the temperature on the ground is too high, and the temperature under the ground is too low, in this case, the aboveground part will grow, and the underground part can not provide water and nutrients to the plant normally, so it will lack nutrients and water, which will affect the growth, and the leaves are easy to yellow. In this case, it is advisable to control the temperature, especially in the early spring.

Hello, I have seen your question and am sorting out the answer, please wait a while

Hello, I've seen your question Ha Now I'm manually replying to the content for you, but it takes a little time, please be patient for a while, thank you, thank you

How to solve this?

Hello, because of excessive watering, the potting soil is too wet for a long time, resulting in a lack of oxygen in the soil, causing some fibrous roots to rot, hindering normal respiration and absorption of water nutrients, causing the leaves to turn yellow and fall off. Due to the limitation of the volume of the pot, the roots can not stretch freely downward and around, so the development of the root system is hindered, if the management is not good, improper watering, fertilization, it will be more prone to yellow leaves than open field flowers.

Do you think there's anything else you can help with?

Is there any medicine for this?

I said this is the kind of wild one, not the kind of my own home.

Hello, ferrous sulfate solution can be poured to replenish iron.

The loss of leaves of Korean pine seedlings may be caused by changes in the environment, so determine the appropriate environment and do not change it easily, and wait for adaptation after changing the environment. It may also be caused by a lack of light or too much light, so you need to keep good light but not bright light. It may also be because of watering, too much watering or lack of water will drop leaves, or improper fertilization will also drop leaves, should be reasonably adjusted fertilization, avoid the use of raw fertilizer, thick fertilizer.

Specific causes and solutions:

1. Environmental change.

During maintenance, if the environment changes and is no longer the original growing environment, the surrounding temperature and humidity have changed, which will make it difficult to adapt and cause the leaves to fall. If you determine the right growth environment, you should not change it easily, and if you change the environment, you can wait for it to adapt to it.

2. Illumination. It is suitable for growing in bright light, if there is a lack of sunlight for a long time, or if the light is too strong, it will cause problems in the growth of the plant, causing the leaves to turn yellow and fall off. It can be kept in good light, and cannot lack sunlight or be exposed to strong light.

3. Watering. Lack of water will cause the leaves to dry up and fall, and if you water too much, the roots will accumulate a lot of water, causing the roots to rot and not being able to absorb water and fertilizer properly, causing leaf loss. Normal watering replenishes water, once there is too much water, it is time to reduce watering, strengthen ventilation to promote the flow of accumulated water.

Fourth, the lack of water fertilizer will not grow well, causing leaves to fall, if too much fertilizer, it may also lead to leaf loss. Fertilization should be reasonably adjusted, you can apply some Haihai and Weihai microbial agents + potassium dihydrogen phosphate, improve soil permeability, supplement high-quality phosphorus and potassium, help Korean pine seedlings grow, and avoid the use of thick fertilizer and raw fertilizer.

Hello, there may be a variety of reasons for the yellow leaves of pine seedlings, and here are some possible reasons:1Improper maintenance:

Pine seedlings need plenty of sunlight and the right amount of water, and if there is not enough sunlight or too much or too little moisture, it will cause yellowing of the bottom leaves. 2.Lack of fertilizer:

Pine seedlings need the right amount of nutrients to grow, and if the soil lacks the necessary nutrients, the bottom leaves will appear yellowing. 3.Pests and diseases:

Pine seedlings are susceptible to some pests and diseases, such as aphids, powdery mildew, etc., which will cause yellowing of the bottom leaves. 4.Soil Issues:

If the soil is too acidic or alkaline, it will also affect the growth of pine seedlings, and the burial will lead to yellowing of the bottom leaves. <>

<> for the above possible causes, you can take the following measures:1Ensure sufficient sunlight and the right amount of water, and avoid over- or under-watering.

2.Give pine seedlings an appropriate amount of fertilizer to ensure that there are enough nutrients in the soil. 3.

Regularly check whether the pine seedlings are attacked by pests and diseases, and take corresponding control measures in time. 4.Measure the pH of the soil, and if it is too acidic or alkaline, you can take measures to adjust the soil.

In addition, the growth of pine seedlings also needs to pay attention to some details, such as pruning dead leaves in time, maintaining ventilation, avoiding excessive fertilization, etc. <>
