Philodendrons are popular indoor plants, celebrated for their lush foliage and adaptability. Proper watering is essential for their well-being, a technique many find challenging. This guide provides insights into watering philodendron plants, helping them thrive.
Understanding Philodendron Watering Needs
Philodendrons originate from tropical environments, thriving in consistent moisture with well-draining soil. Indoors, allow the top one to two inches of soil to dry out between waterings. To check, insert your finger into the soil; if it feels dry, water the plant. A moisture meter can also provide a precise reading.
Philodendrons prefer consistently moist but never soggy soil, as waterlogged conditions lead to root issues. When watering, ensure enough water drains from the bottom of the pot. This hydrates the entire root ball and encourages deeper root growth.
How to Water Your Philodendron
Top watering involves pouring water slowly over the soil surface until it drains from the pot’s drainage holes. Discard any excess water in the saucer to prevent the plant from sitting in standing water, which can harm roots. This method also helps flush out mineral salt buildup over time.
Bottom watering allows the plant to absorb water from a tray or basin. Place the potted philodendron into a sink or tub with 3-4 inches of room-temperature water and let it soak for at least 45 minutes, or until the topsoil feels damp. This method saturates the soil from the bottom up and benefits plants with compacted soil. Room-temperature water is preferable, as cold water can shock the plant. Allowing tap water to sit for 24 hours can help dissipate chlorine.
Common Watering Problems and Solutions
Incorrect watering causes distinct issues. Overwatering leads to yellowing leaves and a musty smell from the soil. Stems may become mushy, and root rot can develop, characterized by dark, soft, foul-smelling roots. If root rot is suspected, remove the plant, trim diseased roots with sterilized shears, and repot in fresh, well-draining soil. Ensure the pot has adequate drainage holes to prevent future water accumulation.
An underwatered philodendron shows signs like drooping or wilting leaves, which may appear crispy or have brown edges. The soil will look very dry. While drooping can indicate either extreme, checking soil moisture is key to diagnosis. To remedy underwatering, provide a thorough watering, allowing water to drain completely. If the soil is extremely dry, bottom watering can rehydrate the entire root ball more effectively.
Factors Affecting Watering Frequency
Environmental factors influence watering frequency, making a rigid schedule impractical. Pot size and material matter; smaller pots and porous materials like terracotta dry faster than larger plastic or glazed ceramic pots. Ambient temperature and humidity also affect water evaporation and plant transpiration. Higher temperatures and lower humidity necessitate more frequent watering. Philodendrons thrive in humidity levels between 50% and 70%.
Light exposure is another factor; philodendrons in brighter, indirect light require more frequent watering than those in lower light, as increased light promotes faster water usage. The potting mix also impacts water retention and drainage. A well-draining, loose mix with organic matter, like peat moss and perlite, helps prevent waterlogging while retaining moisture. Philodendrons require more water during their active growing season in spring and summer and less during cooler, dormant months.
