The Lemon Lime Philodendron is a popular houseplant known for its vibrant, distinctive bright green and yellow foliage. Its striking appearance, with leaves ranging from golden yellow-green to a bright lime, can instantly brighten any indoor space. This cultivar of Philodendron hederaceum is known for its straightforward care.
Lemon Lime Philodendron Care
Light
The Lemon Lime Philodendron thrives in bright, indirect light, which helps maintain its unique coloration. An east or north-facing window is ideal, providing sufficient light without direct sun exposure. Direct sunlight can scorch leaves, causing them to fade or brown. While the plant tolerates lower light, prolonged dim conditions can lead to leggy growth and less vibrant leaves. Supplemental grow lights can be used if natural light is insufficient.
Watering
The Lemon Lime Philodendron prefers consistently moist, not waterlogged, soil. Water thoroughly when the top 1-2 inches of soil are dry to the touch. Overwatering can lead to root rot, so ensure proper drainage. Brown, crispy leaves indicate underwatering. Water more frequently during spring and summer growth, reducing in cooler winter months.
Soil
A well-draining, airy, and rich organic matter soil mix is ideal. This plant prefers a slightly acidic to neutral pH level, typically between 6.4 and 7.5. Combine high-quality potting soil with peat moss or coco coir for moisture retention, and perlite or vermiculite for drainage and aeration. This mix ensures roots get oxygen and prevents water pooling.
Temperature and Humidity
The Lemon Lime Philodendron prefers warm, consistent temperatures, ideally 60°F to 85°F (15°C to 29°C). It is sensitive to cold drafts and temperatures below 55°F (13°C), which can damage foliage. While it adapts to average household humidity, it thrives in higher humidity, ideally 50% or more. To increase humidity, use a humidifier, pebble tray, or group plants.
Fertilizing
During its active growing season in spring and summer, fertilize regularly. Use a balanced liquid fertilizer, diluted to half strength, once every 4 to 6 weeks. This provides nutrients for robust foliage and vibrant coloration. Reduce or pause fertilizing during fall and winter when growth slows. Over-fertilization can lead to salt buildup, causing yellowing leaves or root damage.
Propagating Lemon Lime Philodendron
Propagate Lemon Lime Philodendron through stem cuttings. Select a healthy stem with 2-3 leaves and several nodes (where roots emerge). Using clean, sharp scissors or a knife, cut 4-6 inches below a node. Remove lowest leaves to expose the node. Root cuttings in water or soil.
Water Propagation
- Place the cutting in a jar of room-temperature water, ensuring the exposed node is submerged while leaves remain above the waterline.
- Change the water every few days to keep it fresh.
- Roots typically form within 2-4 weeks.
- Once roots are a few inches long, transfer the cutting to a small pot with well-draining soil.
Soil Propagation
For soil propagation, dip the cut end into rooting hormone if desired. Plant the node in moist, well-draining potting mix, keeping the soil consistently moist until roots establish.
Common Problems With Lemon Lime Philodendron
Common issues often indicate a need to adjust care. Yellowing leaves often signal overwatering, poor drainage, nutrient deficiency, or insufficient light. Check soil moisture and drainage if yellowing is widespread. Brown leaf tips suggest low humidity, underwatering, or excessive direct sunlight. Increase humidity or adjust watering.
Leggy growth (sparse leaves, elongated stems) indicates insufficient light. Move to a brighter, indirect light location for bushier growth. Drooping leaves signal too much or too little water; check soil moisture to adjust. Pests like spider mites or mealybugs require prompt insecticidal soap treatment.
Repotting Lemon Lime Philodendron
Repotting a Lemon Lime Philodendron is recommended every 1-2 years, or when root-bound. Signs include roots emerging from drainage holes, slowed growth, or faster drying. Spring is ideal, coinciding with active growth.
When repotting, choose a new pot only slightly larger than the previous one, typically one size up, to avoid excess soil moisture and root rot. Ensure the new pot has drainage holes. Carefully remove the plant from its current container and place it in the new pot with fresh, well-draining potting mix. After repotting, water thoroughly and place in bright, indirect light to acclimate.
