Pothos plants are popular, resilient houseplants often chosen for their ease of care and attractive trailing foliage. While they generally adapt well to various conditions, understanding their specific watering needs is important for maintaining their health and vibrant appearance.
Visual Signs of Underwatering
A Pothos plant communicates its need for water through several visual cues. One of the most common indicators is drooping or limp leaves, where the rigid foliage loses turgidity and starts to hang downwards. This happens because plant cells rely on water pressure to maintain their structure, and a lack of moisture causes them to become flaccid.
Beyond drooping, leaves may also curl inwards or upwards as the plant attempts to conserve moisture. Additionally, the vibrant green or variegated colors of the leaves might appear dull or faded, losing their characteristic sheen. In more severe cases of underwatering, the edges of the leaves can become dry and crispy, and a slight yellowing may occur, often starting from the tips or edges.
Checking Soil Moisture
Confirming visual cues with a direct assessment of soil moisture helps determine if your Pothos needs water. A simple method is the finger test: insert your finger approximately 1 to 2 inches deep into the soil. If the soil feels dry at this depth, the plant is ready for watering.
Another approach is to lift the pot and assess its weight. A pot that feels significantly lighter than usual suggests the soil has dried out. For a more precise reading, a soil moisture meter can be used by inserting its probe into the soil. A reading between 1 and 3 on a moisture meter scale indicates the soil is dry enough for watering.
Watering Your Pothos
Once your Pothos needs water, thorough watering is beneficial. Apply water until it begins to drain from the bottom of the pot, ensuring the entire root system receives moisture. Proper drainage is essential to prevent waterlogging and root rot, so using a pot with drainage holes is highly recommended. After watering, promptly empty any excess water collected in the saucer.
The frequency of watering varies based on environmental factors, such as pot size, light exposure, humidity levels, and the current season. For instance, plants in brighter light or warmer conditions may dry out more quickly and require more frequent watering. It is generally better to allow the soil to dry out between waterings rather than adhering to a strict schedule, as Pothos are relatively tolerant of slight underwatering but susceptible to issues from consistent overwatering.
