What to Do When Pothos Leaves Turn Yellow in Winter? Causes and Solutions

Pothos (Epipremnum aureum) is a green plant popular in all four seasons, evergreen year-round, highly ornamental, and it also purifies harmful gases such as formaldehyde, toluene and xylene very effectively, making it very suitable for indoor cultivation. But in winter, many friends find that the pothos they grow keeps getting yellow leaves, as if it is about to die. What is the reason for this? Let's take a look.

1. Improper watering

Given winter temperatures, pothos generally stops growing at this time, so watering frequency should be reduced and fertilizing stopped. If too much water is given at this time, the root system of the pothos can easily die, which shows up as yellowing leaves.

Solution: After the start of winter, as temperatures drop, watering frequency should be appropriately reduced. If the leaves have already turned yellow, and if they have only just turned yellow, you can put the plant in the sun to dry out; if the situation is fairly serious, then you should consider repotting.

2. Poor air circulation

Because winter temperatures are bitterly cold, people rarely open doors and windows, which means the air in the indoor environment cannot circulate. Pothos growth thrives in a well-ventilated environment, so poor air circulation and poor air quality will cause the leaves to turn yellow.

Solution: After the start of winter, when temperatures are lower, it is indeed not advisable to keep doors and windows open for long periods. We can open the windows for ventilation for a few hours at noon on a sunny day; this benefits both people and plants.

3. Insufficient humidity

Winter is naturally rather dry, and combined with the bitter cold, air conditioning or heating is usually turned on, which makes the indoor air even drier. Dry weather causes the leaf surface of pothos to lose water, and this also leads to yellowing leaves.

Solution: During care, you can frequently spray water or mist the leaves; this can noticeably increase the humidity in the air and ensure the pothos leaves keep their normal color.

4. Low-temperature cold damage

Pothos is not tolerant of low temperatures. If winter temperatures are too low and moisture is insufficient, it will cause root rot in the pothos, resulting in an inadequate water supply from the roots; the visible symptom is that the leaves begin to turn yellow, and the top leaves of the pothos lose their luster. In addition, if the pothos is hit by cold outdoor air, it will also show yellowing leaves.

Solution: For root rot, you can drench the roots with root rot remedy (Genfuling). If it has no effect, then you should consider selecting healthy leaves for re-propagation by cuttings.
