Heartleaf philodendron care guide
Philodendron hederaceum
Also known as: Philodendron scandens, Philodendron oxycardium, Philodendron 'Brasil'
Pets and children
Considered toxic
Leaves and stems contain calcium oxalate; chewing causes mouth pain, drooling, and vomiting, so place it where the trailing vines are out of reach and consult a veterinarian, or a doctor for a child, if eaten.
How often to water Heartleaf philodendron
- Spring–Summer (Mar–Sep)
- Every 5 days
- Water thoroughly when the topsoil dries, as a guide; in midsummer it dries quickly, so water before the leaves wilt.
- Autumn (Oct–Nov)
- Every 7 days
- Generally water a day or two after the soil dries, cutting back as growth slows.
- Winter (Dec–Feb)
- Every 10 days
- Water lightly about three to four days after the soil dries, and mist the leaves against dry heated air.
Light and placement for Heartleaf philodendron
Bright shade generally suits it and it tolerates a fairly dim room; direct sun scorches the leaves, and variegated forms keep their color best in brighter light.
Overwintering Heartleaf philodendron
Overwintering guide: 8°C (46°F) or above
It overwinters indoors above roughly 8°C; move it back from the window when nights drop under about 10°C and water sparingly to keep the roots from chilling.
Fertilizing and repotting Heartleaf philodendron
Fertilizer
During growth from May to September, diluted liquid feed about once or twice a month is enough; it grows with little feeding, but a bit improves the leaf color, and it needs none in winter.
When to repot
Spring–Summer (Mar–Sep)
Common problems with Heartleaf philodendron
- Constantly wet soil rots the roots and the leaves turn yellow.
- Too dark a spot stretches the vines and thins out the leaves.
- Winter chill blackens the leaves and the vines die back.
Tips for growing Heartleaf philodendron
- Regular trimming brings new shoots from the nodes and a denser plant.
- Cut vines root in water, so you can multiply it and plant the cuttings together.
- In a hanging pot the vines cascade nicely, but it dries faster, so watch for drying out.
These are AI-generated general guidelines. They vary with the variety, the placement and the pot size. For effects on pets or children, consult a veterinarian or a doctor.
