Why do pothos leaves turn yellow in winter? Causes analyzed

Pothos is a very common plant in our daily lives, and because it can survive as soon as it touches water, it is called “the flower of life”. Normally, pothos is an evergreen plant in all four seasons, and even in winter it is lush and green, very endearing, but some people's pothos is usually healthy and thriving, yet once winter comes its leaves turn yellow, so what is going on with pothos leaves turning yellow in winter? Qinnong Web introduces it for everyone below.

To know what to do when pothos leaves turn yellow in winter, we first need to know why the leaves turn yellow in winter. Qinnong Web has summarized five points here for everyone. Through these five causes and the corresponding solutions, we believe we can handle the vast majority of winter pothos leaf yellowing problems.

1. Excessive fertilizing

Because winter temperatures are relatively low, we usually move pothos placed outside indoors for growing. At this time the growth rate of pothos slows down, or it directly stops growing, so at this time fertilizing should be reduced or stopped. If too much fertilizer is applied, it can easily cause root and leaf yellowing and dropping.

Solution:

After winter begins, reduce the amount of fertilizer, and mainly apply fertilizer by foliar spraying, mainly spraying through the stomata on the leaf surface; nutrients are absorbed through the stomata on the leaf surface, and the fertilizer effect can act directly on the leaf surface. Of course, for this kind of fertilizer we cannot choose the ordinary inorganic fertilizer we usually use, but rather some fertilizers specially made for foliage.

2. Insufficient light

Pothos is a shade-loving plant and normally does not need too much light, but winter sunlight is relatively weak. If pothos is placed in a darker place for a long time, due to lack of chlorophyll, the leaves will tend to turn yellow, especially the newly grown leaves.

Solution:

In winter, after moving pothos indoors, try to place it in a balcony, living room, or other place with sufficient light. If the placement location is relatively dark, then when the weather is better, move the pothos to an environment with sufficient light, let it recover for a period of time, and then put it back in its original place.

3. Excessive watering

If there is too much water in the pothos soil or container, it will also cause yellow leaves. The leaf surface will appear dull yellow and lusterless, and problems such as root rot may even appear.

Solution:

Strictly control the amount of watering in winter, water appropriately, and water after the potting soil becomes dry. Be sure to avoid waterlogging.

4. Poor ventilation

Pothos likes a cool and ventilated growing environment. Because winter temperatures are very low and indoors in the north there is heating, many people like to keep doors and windows tightly closed. This is actually extremely unfavorable to the growth of pothos. In winter the indoor temperature should not be too hot, and attention should be paid to ventilation, otherwise dry heat will also cause green leaves to turn yellow. It is necessary to open windows for ventilation and water more to ensure nutrition.

5. Dry air

Similarly, due to the influence of heated rooms and air-conditioned rooms, although the indoor temperature is not low, the air humidity is very low. Pothos is a moisture-loving plant, so certain humidifying measures are needed to ensure the normal growth of pothos.

Solution:

1. A humidifier can be used to regulate indoor air humidity. Place the pothos next to the humidifier so that the pothos can directly come into contact with the mist sprayed out by the humidifier;

2. A sprayer can be used to spray water on the leaves and stems of the pothos at irregular intervals to keep a certain amount of moisture on the leaves and stems. Water can also be kept in the saucer of the flowerpot, and evaporation will also keep the air humidity around the pothos in a relatively stable state;

3. A wet towel can be used to gently wipe the pothos leaves at irregular intervals. Since the whole pothos plant is non-toxic, there is no need to worry about a poisoning reaction from contact with pothos. Toilet paper dipped in water can also be used to gently cover the leaf surface, keeping it for 1 to 2 hours each day;

4. You can manually create a small greenhouse environment for the pothos, that is, directly cover the plant with a transparent film. In this way, water evaporated from the soil can be supplemented to the plant, but the time must not exceed two hours per day, otherwise it will affect the plant's photosynthesis and ventilation.

The above is what Qinnong Web introduces for everyone about the causes and solutions of pothos leaves turning yellow in winter. We hope it can bring some help to everyone. In addition, the aerial roots of pothos are very developed, and pothos can also be grown by hydroponics!
