Philodendron

Quick Overview

• 🌞 LIGHT: Medium to bright, indirect light (tolerates lower light).

• 💧 WATERING: Water when the top 50% of soil (top 1–2 inches) is dry.

• 🌡️ TEMPERATURE & HUMIDITY: 65–80°F (18–27°C) & 50%+ humidity.

• 🌱 SOIL: Loose, chunky, well-draining potting mix with a drainage hole.

• ❗ SAFETY NOTE: Toxic to pets and humans if ingested (contains insoluble calcium oxalate crystals). Keep out of reach.

All the Details

🌞 More about LIGHT

• Tolerates: Medium or lower indirect light, though growth will slow and stems may stretch.

• Avoid: Direct, harsh afternoon sunlight, which easily scorches and dulls the foliage.

• Pro Tip: Variegated varieties (like 'Pink Princess' or 'Birkin') require brighter indirect light to maintain their distinct leaf patterns and prevent new leaves from reverting to solid green.

💧 More about WATERING

• Frequency: Typically every 7–10 days during active spring and summer growth.

• Avoid: Overwatering—Philodendrons prefer their soil to breathe between waterings. Never leave the pot sitting in standing drainage water.

• Taco Test: Leaves that feel firm and crisp are well-hydrated; slightly soft or drooping leaves indicate it's time to water.

🌡️ More about TEMPERATURE & HUMIDITY

• Draft Sensitivity: Keep clear of cold winter drafts, exterior doors, and direct AC vents. Temperatures below 55°F (13°C) cause chilling injury and leaf discoloration.

• Humidity Boosts: Adaptable to standard home humidity, but thrives in 50–70% humidity. High humidity encourages larger leaves and healthier unfurling of new foliage.

🌱 More about SOIL & REPOTTING

• Soil Mix: Needs an airy, porous mixture that prevents water logging. Combine 2 parts standard potting soil, 1 part perlite or pumice, and 1 part coarse orchid bark.

• Repotting: Repot every 1–2 years in spring. Climbing varieties benefit from adding a moss pole or trellis at repotting time to support vertical leaf expansion.

🌸 FERTILIZING

• Routine: Feed monthly during spring and summer using a balanced liquid houseplant fertilizer diluted to half-strength.

• Rest Period: Hold off on fertilizing during late autumn and winter when active growth cools down.

✂️ PRUNING & MAINTENANCE

• Pruning: Trim long trailing vines or leggy stems just above a node using clean, sharp shears to encourage bushier growth.

• Cleaning: Gently wipe leaves with a soft, damp cloth to remove dust buildup and allow the plant to photosynthesize efficiently.

🪴 PROPAGATION

• Stem Cuttings (Water or Soil):

  1. Cut a 4–6 inch healthy stem section directly below a leaf node, ensuring it has 2–3 leaves and at least one node/aerial root.

  2. Place in water or plant directly into a moist, airy potting mix.

  3. Keep warm in bright, indirect light; roots typically form within 2–4 weeks.
