Everything it needs
9 essentials at a glance
Watering
Water your Philodendron Hederaceum when the top 1-2 inches of soil feel dry.
In general, this plant prefers to be on the drier side, so water every 1-2 weeks, adjusting frequency based on humidity and temperature. During the growing season (spring and summer), you may need to water more frequently. Signs of over-watering include yellowing leaves and root rot, while under-watering may cause wilting and crispy leaf edges.
Light
Philodendron Hederaceum thrives in bright, indirect light but can tolerate low light conditions.
Ideally, place it near a window with filtered sunlight for about 6-8 hours a day. Avoid direct sunlight, as it can scorch the leaves. This plant can adapt to partial shade, but growth may slow down in lower light conditions.
Soil
The ideal soil for Philodendron Hederaceum is a well-draining potting mix, rich in organic matter.
A pH range of 5.5 to 7.0 is optimal. You can use a standard potting soil mixed with perlite or orchid bark to improve drainage. Ensure the pot has drainage holes to prevent waterlogging.
Humidity
This plant prefers humidity levels between 40-60%.
To increase humidity, you can mist the leaves, use a pebble tray with water, or place a humidifier nearby. Signs of low humidity stress include browning leaf tips and curling leaves. Conversely, excessive humidity can lead to fungal issues.
Temperature
Philodendron Hederaceum thrives in temperatures between 65-80°F (18-27°C).
It is not frost-tolerant and prefers to be kept above 50°F (10°C). This plant is suitable for USDA hardiness zones 10-12. Avoid placing it in drafty areas or near heating vents, as sudden temperature changes can stress the plant.
Fertilizing
Use a balanced liquid fertilizer with an NPK ratio of 20-20-20 or 10-10-10 every 4-6 weeks during the growing season.
Reduce feeding in fall and winter when the plant is dormant. Signs of nutrient deficiency include yellowing leaves (nitrogen deficiency) and stunted growth (phosphorus deficiency).
Pruning
Prune your Philodendron Hederaceum in spring to maintain its shape and remove any dead or yellowing leaves.
Use clean, sharp scissors or pruning shears. You can also pinch back stems to encourage bushier growth. Deadheading is not necessary for this plant.
Repotting
Repot your Philodendron Hederaceum every 1-2 years or when you notice roots growing out of the drainage holes.
Choose a pot that is 1-2 inches larger in diameter. Signs it needs repotting include stunted growth and water pooling on the surface. To repot, gently remove the plant from its pot, loosen the roots, and place it in fresh soil.
Propagation
You can propagate Philodendron Hederaceum through stem cuttings or division.
For stem cuttings, take a cutting with at least one node and a few leaves, place it in water or moist soil, and keep it warm and humid. Roots should develop in 2-4 weeks. Division can be done during repotting; separate the root ball into sections, ensuring each has roots and leaves.
When it's unhappy
Yellow leaves
Why it happens
Over-watering or nutrient deficiency.
How to fix it
Check the soil moisture and reduce watering frequency. Fertilize with a balanced fertilizer if nutrient deficiency is suspected.
Brown leaf tips
Why it happens
Low humidity or underwatering.
How to fix it
Increase humidity levels by misting or using a humidifier, and ensure you are watering adequately.
Leggy growth
Why it happens
Insufficient light.
How to fix it
Move the plant to a brighter location with indirect sunlight to encourage bushier growth.
Root rot
Why it happens
Over-watering and poor drainage.
How to fix it
Remove the plant from the pot, trim away rotten roots, and repot in fresh, well-draining soil. Adjust watering habits.
Pests (e.g., spider mites, aphids)
Why it happens
Low humidity and poor air circulation.
How to fix it
Increase humidity and wipe leaves with a damp cloth. Use insecticidal soap or neem oil to treat infestations.
Care through the year
Spring
In spring, increase watering frequency as the plant begins to actively grow. Fertilize every 4-6 weeks to support new growth.
Summer
During summer, ensure the plant receives bright, indirect light and maintain humidity levels. Water regularly, allowing the soil to dry out slightly between waterings.
Fall
In fall, gradually reduce watering as the plant's growth slows. Continue to fertilize until late fall, then stop for the winter months.
Winter
In winter, keep the plant in a warm location away from drafts. Water less frequently, allowing the soil to dry out more between waterings, and avoid fertilizing.
Toxicity & Safety
Philodendron Hederaceum is toxic to pets (cats and dogs) and humans if ingested. The leaves contain calcium oxalate crystals, which can cause irritation, swelling, and digestive issues. Symptoms of ingestion may include mouth and throat irritation, vomiting, and difficulty swallowing.
