Care Guide
Heartleaf Philodendron Care Guide ### Light Provide bright, indirect light for optimal growth, though it is famously tolerant of low-light conditions. Avoid direct sunlight which can scorch the foliage. ### Watering Water when the top inch of soil feels dry to the touch. It is better to underwater than overwater this species, as it is prone to root rot in soggy soil. ### Humidity and Temperature Maintain temperatures between 65°F and 85°F. While it handles average indoor humidity well, it will thrive with higher humidity levels. ### Maintenance Regularly prune the vines to maintain the desired shape and encourage fuller growth. Wipe the leaves with a damp cloth to remove dust and maintain photosynthesis efficiency.
