The money plant, or Pothos (Epipremnum aureum), is a popular indoor houseplant. Proper watering is crucial for its health and vibrant appearance. However, watering frequency is not a fixed schedule, as it depends on various environmental and situational factors unique to each plant’s growing conditions.
Knowing When to Water
The most reliable way to determine if a money plant needs water is by checking the soil moisture directly. Use the “finger test” by inserting your finger one to two inches deep into the soil. If it feels dry at this depth, the plant is ready for water; if moist, wait a few days.
A moisture meter can also provide a precise reading of the soil’s moisture content. Beyond soil checks, the plant often displays visual cues when thirsty. Slightly drooping or wilting leaves can signal a need for water, though it is important to confirm with a soil check as these symptoms can also point to other issues. Ideally, water before the leaves shrivel or become dry.
Factors Affecting Watering Frequency
Several factors influence how quickly a money plant’s soil dries out, directly impacting watering frequency.
Light Exposure
Plants in brighter, indirect light use water more rapidly, requiring more frequent watering than those in low-light conditions.
Temperature
Warmer temperatures accelerate water evaporation, necessitating more frequent hydration. Conversely, cooler temperatures slow moisture loss, reducing the need for water.
Humidity
Lower humidity can lead to faster drying of the soil and increased watering needs.
Pot Size and Material
Smaller pots tend to dry out faster than larger ones due to less soil volume. Porous materials like terracotta wick moisture away more quickly than plastic or glazed ceramic pots.
Soil Type
A well-draining, airy potting mix will dry faster than dense, moisture-retentive soil.
Seasonal Changes
Plants generally require more water during their active growing season in spring and summer, and less during the dormant fall and winter months.
Best Practices for Watering
When a money plant indicates it needs water, a thorough watering technique is recommended. Pour water slowly over the soil until it begins to drain from the pot’s drainage holes. This ensures that the entire root ball is saturated, promoting healthy root development. Adequate drainage is crucial to prevent waterlogging, which can suffocate roots and lead to various problems. Any excess water collected in the saucer should be emptied within 10 to 15 minutes to prevent the plant from sitting in stagnant water.
Both top watering and bottom watering methods are effective, each with specific benefits. Top watering is suitable for immediate hydration, especially if the soil has become very dry. Bottom watering, where the pot absorbs water from a tray, encourages more even saturation of the soil and can be particularly useful for plants with dense root balls or for those prone to overwatering. Using room temperature water is preferable, as cold water can shock the plant’s roots. Avoid giving the plant small, frequent sips of water, as this can lead to shallow root growth and inadequate hydration of the entire root system.
Recognizing Watering Problems
Identifying symptoms of incorrect watering is essential for maintaining plant health.
Overwatering
Overwatering often manifests as yellowing leaves, mushy stems, and foul-smelling or moldy soil due to excessive moisture and lack of oxygen. The most severe consequence of persistent overwatering is root rot, where roots turn brown, soft, and mushy, hindering their ability to absorb water and nutrients. To address overwatering, allow the soil to dry out completely before the next watering, and ensure the pot has proper drainage. If root rot is suspected, removing the plant from its pot, trimming affected roots, and repotting in fresh, dry soil may be necessary.
Underwatering
Underwatering typically causes leaves to wilt or droop, and they may feel crispy to the touch. The soil can pull away from the edges of the pot when severely dry and compacted. Slowed growth can also be a sign of insufficient water. An underwatered plant can often be revived by a thorough watering, allowing the plant to soak up moisture until the soil is rehydrated. If the soil has become hydrophobic, soaking the entire pot in a basin of water for a period can help it reabsorb moisture.
