How to raise indoor potted keel leaves yellow, what to do if keel leaves are yellow

The cold wind blowing in winter is the main cause of leaf yellow, keep it warm and keep it in a sunny place.

The keel leaves are yellow, dry and falling, what's going on.

For the yellowing and falling off of the leaves of the keel flower, there are the following solutions according to different reasons:

1. Keel flowers fall leaves in winter. If it is during the defoliation period in winter, due to metabolic reasons, it is a natural thing for the leaves to turn yellow and fall off, so there is no need to worry too much.

2. Too much water. If there is too much water, the rotten roots and leaves will be yellow. Workaround: Stop watering.

3. Lack of fertilizer. Pay attention to fertilization. Control method: It is best to use slow-release fertilizer.

4. Infection with germs. Sick and withered and dying. Prevention and control method: carbendazim can be used as medicine and poured on the roots of plants.

After winter, the yellowing and falling off of the leaves of the keel flower is a normal physiological phenomenon, and the potted keel flower is usually moved to an environment with a temperature greater than 10. Keel flowers are drought tolerant, but they are also afraid of waterlogging, and too much watering will affect the respiration of the roots, and then rot, and over time, the leaves will also turn yellow. If this is the case, the watering should be stopped immediately and placed in a ventilated place.

Usually water the keel flowers, an appropriate amount, to avoid problems such as potting soil water accumulation.

First, the normal reason: the keel flower will cause its leaves to appear yellow because of a variety of factors, first of all, the keel flower will appear when the leaves are yellow, usually during the defoliation of the keel flower, the yellowing of the leaves at this time is a relatively normal phenomenon, they only need to remove the yellowing leaves.

2. Proper watering: the second phenomenon is caused by the watering of the keel flower more, if the watering is too much, the root of the keel flower will be waterlogged, which affects the nutrient absorption of the root system, and the root rots out, so that the phenomenon of yellow leaves appears.

As soon as this happens, you need to stop watering immediately. Keel flowers will enter dormancy in winter, and it is not suitable for too much water at this time, so it is okay to water once a month or two.

In the spring, a thorough watering half a month is sufficient. In summer, the amount of evaporation is relatively large, and it is necessary to water once a day in the morning and evening to avoid the appearance of yellow leaves.

<> yellowing of the leaves of keel flowers may be a natural phenomenon in the process of growth, and the yellow leaves can be removed in time, or it is caused by improper maintenance, such as excessive watering and soaking roots, insufficient light, sluggish growth or too strong light to burn the leaves, improper fertilization caused by fertilizer problems, etc., may lead to yellowing of leaves.

1. Yellowing due to normal causes.

Many plants such as keel flower in the process of natural growth in Xiangzhou, will inevitably appear leaf yellowing, which is a normal phenomenon of plant growth metabolism, often only need to remove the yellowing leaves, this situation of yellowing will not affect the normal growth of the plant.

Second, caused by excessive watering.

If the amount of watering is not well controlled, resulting in water accumulation in the potting soil, it will be easy to soak the roots and cause the roots to rot, affecting the absorption of water and nutrients, so that the leaves are yellow, and it is necessary to stop watering in time, discharge excess water, and loosen the soil for ventilation.

3. Insufficient or too strong light.

Insufficient light or after a long period of strong light exposure, it will also cause the leaves to turn yellow, keel flowers need appropriate sunlight every day to promote photosynthesis, conducive to plant growth, better flowering, but also pay attention to not in the strong light exposure, need proper shade, to ensure that the plant has proper astigmatism. Posing.

Fourth, fertilization and maintenance.

Keel flower growth also needs proper fertilization to promote growth and development, if the long-term lack of nutrients or too much fertilization leads to fertilizer damage, there may be yellowing of leaves, the vigorous growth period of appropriate application of thin liquid fertilizer can be, can not use raw fertilizer or thick fertilizer, to ensure the normal nutrition needed for plant growth.

First, the cause of soil drought: in the breeding keel flower to give it water on time, only the soil has enough water, it can grow well. However, if there is no water supply for a long time, the soil will become very dry, and the plants will naturally lack water, so the leaves will yellow.

Improvement method: It should be watered thoroughly to replenish the lack of water in the soil, and after the plant absorbs a certain amount of water, it can really improve this undesirable phenomenon.

2. Improper light reasons: try to give it a suitable environment when maintaining, and not let it be exposed to strong sunlight, and the leaves will turn yellow after being sunburned. On the contrary, if it does not receive light for a long time during the growing period, its leaves cannot photosynthesize and will also turn yellow.

How to improve: If it is caused by sunburn, put the plant in a low-light location and give it a little water. If it is caused by a lack of light, just put it in a well-lit place.

3. Reasons for weak ventilation: When raising indoors, if the window is not opened for a long time, it will not be able to accept fresh air, and it will slowly yellow leaves. Especially in winter, combined with the low temperature, it is easier to make the leaves yellow.

Improvement method: You can move to a place with good outdoor air to raise, or you can open more windows in the morning so that it can better absorb air.

Keel flower leaves yellow?Solve the "problem" in time, stout and straight, and quickly return to verdant green.
