🌱 About the Plant
The Heartleaf Philodendron (Philodendron hederaceum) is one of the easiest and most reliable indoor foliage plants. Its attractive heart-shaped leaves grow along trailing stems, making it ideal for hanging baskets, shelves or training up a moss pole or support.
With the right conditions, it can become a vigorous, lush plant and is particularly forgiving of occasional neglect.
 
💡 Light
Best growth occurs in bright, indirect light, but Philodendron hederaceum also tolerates lower-light conditions.
Avoid harsh direct midday or afternoon sun, which can scorch the leaves.
Too little light will result in slower growth and longer spaces between leaves.
A few hours of gentle morning sun can be beneficial.
Tip: Variegated forms generally require more light than green forms.
 
💧 Watering
Allow the top 2–4 cm of growing medium to dry before watering again.
When watering, soak the medium thoroughly and allow excess water to drain away. Do not allow the pot to stand permanently in water.
Watering frequency will depend on temperature, light, pot size and growing medium. Avoid watering on a fixed schedule if the soil is still wet.
Yellow leaves + consistently wet soil = usually too much water.
 
🌡️ Temperature & Humidity
Ideal temperature: 18–28°C
Keep away from cold draughts and prolonged temperatures below 12–15°C.
Normal household humidity is usually sufficient, although higher humidity can encourage larger, healthier leaves and faster growth.
 
🌱 Potting Mix
Use a loose, well-draining and aerated mix that retains some moisture without becoming waterlogged.
A suitable mix can contain:
Coco coir or quality potting medium
Fine orchid bark
Perlite or pumice
Ensure the container has adequate drainage holes.
 
🌿 Feeding
Feed during active growth with a balanced liquid houseplant fertiliser at approximately ¼–½ the recommended strength every 2–4 weeks.
Reduce feeding during periods of slow growth.
Avoid excessive fertiliser, as salt accumulation can damage the roots and cause brown leaf edges.
 
✂️ Pruning & Training
Heartleaf Philodendrons respond very well to pruning.
Trim long or sparse stems just above a node to encourage a fuller appearance. Cuttings can also be propagated to produce additional plants.
For larger leaves and a more mature appearance, train the plant to climb a moss pole or other suitable support. A climbing plant can produce significantly larger leaves than a plant allowed to trail.
🌱 Propagation
The easiest method is stem cuttings.
Take a cutting containing at least one healthy node and place it in water, sphagnum moss or a suitable propagation medium. Keep it warm and humid with good indirect light.
Once a healthy root system has developed, transplant into a suitable growing medium.
 
⚠️ Common Problems
Yellow leaves: Often caused by overwatering or poor drainage.
Brown/crispy edges: Can result from underwatering, very dry air or excessive fertiliser.
Small leaves: Usually associated with insufficient light, lack of climbing support or immature growth.
Long gaps between leaves: Usually indicates insufficient light.
Pests: Watch for mealybugs, scale, thrips and spider mites.
🐾 Pet Warning
Philodendron hederaceum contains calcium oxalate crystals and is toxic if chewed or ingested. Keep away from pets and children.
