Similarly, whenever you see your heartleaf philodendrons sprouting new leaves, consider adding a bit of fertilizer to boost their growth. 3. __Give them bright light__. Bright, indirect light conditions are best for heartleaf philodendron plants. Low light is preferable to direct sun if you can’t provide indirect sunlight.
