About this plant
Philodendron ‘Red Heart’, commonly called Red Heart Philodendron, is a tropical climbing philodendron grown for its deep green foliage and rich red-toned new growth and stems. This cultivated hybrid is prized for its warm coloration and vigorous climbing habit. What makes this plant special is the contrast between the darker mature leaves and the reddish undersides, petioles, or emerging foliage depending on maturity and lighting. The leaves are elongated, heart-shaped, and slightly glossy, growing larger as the plant climbs.

Light requirements
Place Philodendron ‘Red Heart’ in an east or south window for the best color and growth, positioned at the window or within 1 to 3 feet depending on intensity. A west window can work if slightly pulled back from harsh late-day sun, while a north window will slow growth and reduce the red tones. Under grow lights, use 5000K to 6500K and keep the light 8 to 12 inches above the canopy. It performs best around 300 to 800 foot-candles. Consistent bright light supports stronger coloration and larger foliage.

Watering & environment
Allow the soil to dry about halfway down before watering, and always check the root zone with a chopstick or meter. Use a chunky, well-draining mix with support for climbing as the plant matures. It prefers moderate to higher humidity, warm temperatures, and steady airflow to support healthy root and leaf development.

What your plant is telling you
If leaves begin to droop or feel thinner, it is ready for water. If leaves yellow quickly or the stem base softens, the soil is staying too wet. If new growth loses its red coloration or leaves remain small, it needs more consistent light or vertical support.
