Epipremnum plants, often known as Pothos or Devil’s Ivy, are popular houseplants appreciated for their trailing vines and attractive foliage. Proper watering is important for their health and appearance.
Knowing When to Water Epipremnum
Determining the right moment to water an Epipremnum plant involves checking the soil moisture, rather than adhering to a rigid schedule. The most common method is the “finger test,” which involves inserting your finger about one to two inches deep into the potting mix. If the soil feels dry at that depth, it is time to water.
A moisture meter offers a more precise measurement of soil moisture throughout the pot. Subtle visual cues, such as a slight droop in the leaves, can also signal a thirsty plant. However, it is best to water before the plant shows significant signs of wilting. Allow the top layer of soil to dry out between waterings to prevent the plant from sitting in consistently wet conditions.
The Right Way to Water Epiprepnum
When watering an Epipremnum, water thoroughly until water begins to drain from the bottom of the pot. This ensures the entire root ball receives adequate moisture. Always use pots with drainage holes to prevent water from accumulating, as prolonged standing water can lead to root rot.
Bottom watering is an alternative method where the plant absorbs water from a tray beneath the pot, leading to even saturation. While effective for thorough hydration, top watering is more commonly practiced. Avoid frequent, shallow watering, as it can lead to poor root development and mineral buildup by not encouraging roots to grow deeper.
Factors Affecting Epipremnum Watering Needs
Several environmental and plant-specific factors influence an Epipremnum’s watering needs:
- Light levels: Plants in brighter, indirect light dry out faster and require more frequent watering due to increased evaporation. Conversely, plants in lower light conditions need less water.
- Temperature and humidity: Warmer temperatures and drier air increase water evaporation from the soil and leaves, requiring more frequent watering. Cooler temperatures and higher humidity reduce water needs.
- Pot size and material: Smaller pots dry out more quickly than larger ones. Porous terracotta pots allow faster moisture evaporation compared to non-porous plastic or glazed ceramic pots.
- Soil type: A well-draining, aerated potting mix allows water to pass through quickly, necessitating more frequent watering than heavy, moisture-retentive soils.
- Season: Watering needs generally decrease during winter months due to slower plant growth and reduced light exposure.
Troubleshooting Common Watering Problems
Overwatering is a common issue for Epipremnum plants, indicated by specific symptoms. Yellowing leaves, especially on lower parts, are a common sign. Mushy stems, stunted growth, and a foul odor from the soil also indicate excess moisture and potential root rot. If these symptoms appear, allow the soil to dry out thoroughly before the next watering. Inspecting roots for rot (dark, mushy roots) and repotting into fresh, dry soil after trimming affected roots can help save the plant.
Underwatering also presents distinct signs, though less common for these resilient plants. Drooping or wilting leaves are a primary symptom, as the plant lacks the internal water pressure to maintain rigidity. Crispy, brown leaf edges and very dry, compacted soil are further indications of insufficient moisture. For severely dry plants, a thorough deep watering, possibly even bottom watering, can help rehydrate the soil and roots. Establishing a consistent watering routine based on soil moisture checks will help prevent future underwatering issues.
