There are plenty of viable ways to supply your Chinese pothos with water. If you grow your plant in an indoor pot, for the Chinese pothoss in small pots, you can bring your potted plant to your kitchen sink. Then, use the faucet to add water to the container. By holding the pot in your hands, you should easily notice when the water begins to run through the pot’s drainage holes, at which point you can stop watering. The cold temperature will hurt the plants' root system, so please don't do this during winter or in cold climates. Most of the time, watering via your faucet is permissible for the Chinese pothos. However, if the local tap water contains a high proportion of fluorine, chlorine or salts, you should consider using rainwater or lake water. Also, since the Chinese pothos can respond well to overhead watering and watering directly into the soil, you can use a watering can, hose, or just about any tool you’d like to water it.

If you discover that you have underwatered your Chinese pothos, your first step towards remedying the situation is to give your plant some water. Water deeply until excess water runs from the container’s drainage hole, or if you grow outside, water until the soil has become entirely moist. If you find your Chinese pothos is receiving too much water, begin by reducing your watering schedule. You also want to address the soil and container your Chinese pothos grows in. If either the soil or the container makes it difficult for water to drain efficiently, your plant will likely become overwatered again. Resolve the issue by moving your plant to looser soils and/or a container with bigger drainage holes or a more porous material. Also check the location of the plant. If the plant is in places like a corner, then it is recommended to move it to a window or around a door to enhance ventilation. Making sure the plants are in a well-ventilated location can reduce the occurrence of overwatering to some extent.

The Chinese pothos is not a species that requires consistent soil moisture. Instead, it is better to allow this plant’s soil to become dry between waterings. If you are like the many gardeners who grow Chinese pothoss in containers, you can judge whether or not it is time to add water by how dry the soil within the container is. For instance, if about top half of the soil in your container has become dry, it is time to add water. You can feel it by inserting your fingers or sticks into the soil or with soil moisture meter. For those who grow the Chinese pothos outdoors, you can plan to do your watering about once every other week, provided it has not rained recently.

After waiting for the first several layers of soil surrounding your Chinese pothos’s root to become dry（top half of the soil）, it is time to add enough water to make them moist again. The amount of water it takes to achieve that goal depends on if you use a container, how large that container is, and how large your plant itself is. For a small Chinese pothos growing in a small to a medium-sized container, one to two cups may be enough to dampen the soil sufficiently. As you would expect, the volume of water you supply should increase for a larger plant. The best way to make sure your plant has received enough water is to stick your finger or a trowel into the soil and feel whether it is entirely moist. Alternatively, you can water until you see excess water draining from the holes at the bottom of your container.

Overwatering and underwatering are both bad for the health of your Chinese pothos. These two issues also manifest themselves in subtly different ways when they occur. Chinese pothos that receives too little water may begin to develop yellow leaves. Underwatering may also cause the leaf margins to become brown and brittle. By contrast, Chinese pothos that gets overwatered will often show yellow and brown marks on its leaves at the same time. Overwatering can also lead to diseases like root rot, some of which may also be visible on your plant. However, if you know the signs of overwatering and underwatering, you stand a good chance of correcting both issues.

During spring and fall, your watering schedule for the Chinese pothos will remain relatively the same, which will involve watering this plant about once every week. During summer, you may find that the hot weather causes your plant to need more water than usual, especially if it grows where there is a considerable amount of daily light exposure. In the winter, if it's hard to find some warm places for you plant, your Chinese pothos will enter a dormant growth phase, in which it will need far less water than usual. At this time, you may get by without watering your plant at all. If you do choose to water during winter, you should not do so more often than once every two to three weeks.

After planting a new, young Chinese pothos or after transplanting an older Chinese pothos, you will probably need to give this plant more water than usual. Young plants often need consistent soil moisture during the early stages of their growth to help them adapt to their new growing locations. Transplants also need more water for a brief time to overcome transplant shock. In either case, you may need to water multiple times per week until your plant has exhibited continuous healthy growth. In most situations, your water should be moderate and should never be significant enough to cause overwatering.

There are a few reasons why you may need to water an indoor Chinese pothos more often than one that grows in the ground outdoors. First, indoor growing settings tend to be drier than outdoor ones, often due to the effect of air conditioning units. While thw size of the pot and the soil determines the warer accumulating ability. Additionally, when your plant grows indoors, it will rely on you entirely for its water By contrast, Chinese pothos that grows outside can receive water from rain. If you are in an area with high rainfall, you may not have to give it extra watering. When there is not enough rain, you should water additionally to ensure that the soil does not dry out completely.

Chinese pothos requires about 3-6 hours of direct sunlight each day to thrive. However, it also needs some shade during the hottest parts of the day to prevent sun damage. Morning sunlight is ideal for Chinese pothos, but it can also tolerate some afternoon sun if the temperature is not too hot. To provide the perfect balance of sunlight, try planting Chinese pothos in an area that gets partial sun, such as under a tree or on the east side of a building.

If Chinese pothos is exposed to too much direct sunlight, its leaves may turn yellow, dry out, or even burn. You may also notice that the plant wilts or becomes stunted. To prevent sun damage, make sure to give Chinese pothos some shade during the hottest parts of the day. You can use a shade cloth or plant Chinese pothos near taller plants that can provide some natural shade.

If Chinese pothos doesn't get enough sunlight, it may grow tall and lanky, with sparse foliage. The leaves may also turn yellow or pale green, indicating that the plant is not producing enough chlorophyll due to lack of sunlight. To remedy this, try moving Chinese pothos to a sunnier spot, or prune nearby foliage to allow more light to reach the plant.
