What s going on with the smooth sailing leaf yellow

If only one or two leaves at the bottom are yellow, it is a normal metabolism and there is no need to worry too much, just cut off the yellow leaves. If there is a large number of yellow leaves, it may be caused by too much watering, so it is necessary to evaporate the soil moisture in time, prune the root system that has rotted due to water accumulation, and then repot the plant. Pay attention to watering control to avoid yellowing of the leaves due to water accumulation again.

The first possibility is that it is too dry or too waterlogged, check the moisture of the soil yourself, and press it with your hand to feel whether it is wet or dry.

The second is the climate, in the northern region, to prevent it from freezing to death if there is no heating inside, cover it with a plastic bag.

Third, it should be ventilated and have light.

The space is not ventilated, watered too often or too little.

Stuffy and unventilated? Too little light for a long time?

Below 10 degrees Celsius, you will get frostbite or even freeze to death.

The reasons for the yellowing of the leaves are as follows:

First, the light is too strong.

For the yellowing of the leaves caused by too strong light, just put it in the indoor culture, and it is better to have astigmatism than too much sunlight.

Second, the humidity is insufficient.

Smooth sailing requires plenty of moisture, so the ambient humidity should not be too dry. If the humidity is below 50%, it is easy for the leaves to turn yellow when it is smooth sailing. This usually happens in air-conditioned rooms, where the air is drier and uncomfortable even for people, including plants.

So many times plants and people have the same perception of the environment.

For the yellowing of the leaves caused by insufficient humidity, as long as the smooth sailing is removed from the air-conditioned room, or the humidifier is used to adjust the indoor humidity and ensure that the moisture is sufficient, the yellow leaves can be alleviated.

3. Stagnant water and rotten roots.

Many people have a misconception that they need plenty of water to water it for smooth sailing, so it is not right. Because if it is smooth sailing with water, there is no need for frequent watering at all; If the soil culture is smooth sailing, it should not be watered frequently, because it is easy to accumulate water and rot the roots, so the leaves will turn yellow.

For the yellowing of leaves caused by stagnant water and rotten roots, as long as the watering method is controlled, the occurrence of yellow leaves can be avoided. Generally, it follows the principle of "not drying and not watering, watering and watering thoroughly", which can not only ensure sufficient water, but also avoid rotten roots and yellow leaves. Normally, watering once a week, you can increase the number of watering times in summer, and pay attention to reducing the frequency of watering in winter.

Of course, if you use hydroponics, you can save the trouble of watering.

Fourth, too much fertilizer.

Plants need fertilizer, but too much fertilizer will burn the roots, and then the leaves will turn yellow. Therefore, the cultivation is smooth sailing and cannot be rushed, otherwise it will only backfire and cannot fully absorb nutrients. For the yellowing of the leaves caused by too much fertilizer, you can master the way of "thin fertilizer and diligent application", so that it is smooth sailing and slowly absorb nutrients, so that it is not easy to yellow the leaves.

5. Pests and diseases.

Pests and diseases can also cause yellow leaves, although this situation is not very common, but when yellow leaves appear, it is still necessary to check whether there are any pests and diseases, and deal with them accordingly in time. If it is yellow leaves caused by pests and diseases, you need to prescribe the right medicine and buy special insecticides to deal with it.

Smooth sailing, yellowing of leaves is the cause of dry air, too much light, improper fertilization, too low temperature, insect infestation, etc.

1. Dry air: smooth sailing leaves are yellow and scorched, which may be caused by dry air first, if the humidity of the maintenance environment is not enough, the tips of the leaves are easy to scorch. For the scorched edges caused by dry air, a humidifier can be placed next to the pot to create a local space with high air humidity for the plants to promote their healthy growth.

2. The light is too strong: smooth sailing is afraid of exposure to the sun, if the maintenance environment is too strong, the leaves are easy to yellow and scorched, and the potted plants need to be moved to a cool and ventilated place, and the yellowed leaves should be cut off in time, so as not to affect the overall ornamental value of smooth sailing. In addition to the full sunlight maintenance in winter, astigmatism maintenance must be carried out in other seasons.

3. Improper fertilization: smooth sailing has a certain demand for fertilizer and water, in the plant growth period need to be thin fertilizer diligently, do not apply too thick fertilizer water, or apply unrotted fertilizer water, otherwise the plant will be prone to fertilizer injury, manifested in rotten roots, yellow leaves, for the appropriate improper caused by yellow leaves, need to be washed with water to wash the pot soil, if necessary, replace the pot soil and replant.

4. The temperature is too low: smooth sailing is particularly afraid of freezing, the potted plants must be moved to indoor maintenance in winter, if the temperature is too low, the leaves are easy to yellow and scorched, for the leaves that have been frostbitten, the yellow leaves need to be cut off in time, and the temperature of the maintenance environment is increased little by little.

5. Insect pest infection: smooth sailing, yellowing of leaves may also be due to infection with pests and diseases, during the breeding period, insecticidal treatment should be carried out regularly for the plant, professional insecticides and pesticides can be sprayed, and a small amount of pepper water can be sprayed for prevention and control.

1. The yellowing of the leaves is because it is smooth sailing without ventilation, ventilation, and sunbathing, try to put it in a ventilated place, every 3 to 4 days, let it bask in the sun, but it can not be exposed to the sun for a long time.

2. If there are leaves that have been yellow, cut off the yellow leaves, and they will grow back in a few days. When watering, it should be watered thoroughly at one time, not just the skin, but once every 1 week in winter, and it should also be watered thoroughly at one time.

Maybe there is too much water, and the roots rot, and the leaves will turn yellow.
