Heartleaf philodendron is a tropical climbing aroid with flexible stems and glossy, heart-shaped leaves. The accepted name for the commonly cultivated heartleaf form is Philodendron hederaceum var. oxycardium.
Follow the vine to check for alternating heart-shaped leaves, papery cataphyll remnants at the nodes, and aerial roots. Unlike pothos, the new leaf usually emerges from a separate sheath rather than directly from the previous petiole.

Light
Use medium to bright indirect light for compact growth and good leaf size. It tolerates lower light, but long gaps between leaves and small new growth signal that the position is too dim.
Watering
Let the upper portion of the Heartleaf Philodendron mix dry, then water the root ball thoroughly and empty runoff. Check moisture below the surface and root condition before responding to limp or yellow leaves.
Soil
Grow Heartleaf Philodendron in an airy houseplant mix amended with coarse bark or perlite. It should hold modest moisture while allowing oxygen back into the center of the root ball after watering.
Fertilizer
Use a diluted balanced houseplant fertilizer for Heartleaf Philodendron while new growth is expanding. Apply it to moist soil and pause when low light or cool conditions slow growth.
Propagation
Cut just below a healthy node so every cutting includes at least one node and leaf. Root in water or an airy moist medium, then pot once several new roots have formed.
Pruning
Remove damaged Heartleaf Philodendron leaves cleanly and shorten a trailing or branching stem just above a healthy node. Avoid removing a large share of the foliage while the plant is stressed.
Temperature
Keep Heartleaf Philodendron near 18°C - 27°C and protect it from abrupt drafts, heater blasts, and hot window glass.
Growing in a container
Heartleaf Philodendron should be repotted when roots are crowded, drainage has slowed, or the mix has broken down—not simply because a larger pot looks attractive. Increase the container only modestly and preserve the original planting depth.
Common problems
Heartleaf Philodendron check: yellowing that begins after soil stays wet for too long.
Heartleaf Philodendron check: brown margins linked to dry roots, low humidity, or salt buildup.
Heartleaf Philodendron check: pests sheltering on leaf undersides and tender new growth.
Beginner rule: change one part of the Heartleaf Philodendron routine at a time, then watch the newest growth before making another adjustment.
Is Heartleaf Philodendron toxic?
