Philodendrons are a favored choice among indoor plant enthusiasts. These adaptable plants, hailing from the tropical forests of Central and South America, thrive in various indoor environments, making them suitable for both seasoned plant parents and those new to gardening.
Exploring Philodendrons from The Sill
The Sill is an online retailer offering a curated selection of Philodendrons. They provide healthy plants, often pre-potted, and ensure specimens are well-packaged to withstand shipping and arrive in good condition.
The Sill offers common Philodendron varieties well-suited for indoor environments. These include the classic Heartleaf Philodendron (Philodendron hederaceum), its ‘Brasil’ cultivar, ‘Pink Princess’ (Philodendron erubescens ‘Pink Princess’), and ‘Prince of Orange’ (Philodendron erubescens ‘Prince of Orange’). They also offer guidance and support for plant care.
General Philodendron Care Essentials
Providing Philodendrons with appropriate conditions helps them thrive. Consistent attention to their environmental needs ensures robust growth and overall plant health.
Light Requirements
Philodendrons flourish in bright, indirect light, mimicking their natural habitat beneath a forest canopy. Place them near an east or west-facing window to receive ample light without harsh direct sun. Direct sunlight can scorch their leaves, causing yellowing or burnt spots. Insufficient light leads to leggy growth. If natural light is limited, supplemental full-spectrum grow lights (around 6500K) can provide necessary illumination for 12-16 hours daily.
Watering Practices
Allow the top 1-2 inches of soil to dry out between waterings. Check moisture by inserting a finger; water when dry. Overwatering can lead to root rot. Ensure water drains through the pot’s drainage holes, and discard any excess collected in the saucer. During cooler months, reduce watering frequency as growth slows.
Soil and Potting
Philodendrons thrive in loose, well-draining potting mixes rich in organic matter. A suitable mix includes coco coir, perlite, and aged bark, providing aeration and moisture retention. This composition prevents waterlogging and promotes healthy root development. A standard houseplant potting mix with added perlite or sand also works. Always choose a pot with drainage holes.
Temperature and Humidity
Philodendrons prefer warm, humid environments, ideally 65-80°F (18-27°C). Protect them from temperatures below 55°F (13°C) and cold drafts. While they adapt to average household humidity, higher levels (50-60%+) encourage larger foliage. Increase humidity with a humidifier, pebble tray, or by grouping plants.
Fertilization
During the active growing season (spring and summer), fertilize Philodendrons regularly. A balanced liquid fertilizer (e.g., 20-20-20), diluted to half or quarter strength, applied monthly or every two weeks, is sufficient. Over-fertilization can cause salt buildup in the soil. Reduce or cease fertilization entirely during fall and winter when growth slows.
Pruning and Repotting Basics
Pruning Philodendrons helps maintain their shape, encourages bushier growth, and removes any yellowing, damaged, or dead leaves. Use clean, sharp shears to make cuts just above a leaf node, which is where new growth typically emerges. This practice redirects the plant’s energy towards producing new foliage.
Repotting is necessary when the plant becomes root-bound, indicated by roots circling the pot or emerging from drainage holes. This typically occurs every 18 months to two years. When repotting, choose a container that is one size larger than the current one and use fresh, well-draining potting mix. The best time for repotting is during the spring or early summer, allowing the plant ample time to establish itself in its new container.
Troubleshooting Common Philodendron Challenges
Philodendrons can occasionally exhibit signs of distress. Recognizing common issues and their causes allows for prompt intervention.
Yellowing or Drooping Leaves
Yellowing leaves indicate improper watering, from both overwatering and underwatering. Overwatering often results in younger, lower leaves turning yellow and mushy, sometimes with a rotting odor. Underwatering causes older leaves to yellow and become crispy, with the plant appearing droopy. Nutrient deficiencies, especially of iron or magnesium, can also lead to yellowing foliage if not fertilized regularly. Additionally, cold drafts or low temperatures can cause leaves to droop and yellow.
Pests and Diseases
Philodendrons are resilient but susceptible to pests like spider mites, mealybugs, aphids, and thrips. These insects cause discoloration, stunted growth, or visible webbing. Inspect leaf undersides and stem joints regularly for early detection. Treat with a gentle solution of water and dish soap, insecticidal soap, or neem oil. Root rot, a fungal issue, is caused by overwatering; ensure proper drainage and dry soil between waterings to prevent it.
Leggy Growth
Leggy growth, with elongated stems and widely spaced leaves, indicates insufficient bright, indirect light. The plant stretches towards a light source, resulting in a sparse appearance. Move the plant to a brighter location, like an east or west-facing window. For severe legginess, pruning encourages bushier growth. Regular rotation also promotes more even, compact growth.
