Heartleaf Philodendron

Give it bright, indirect light for fuller vines and larger leaves. It tolerates medium or low light, but growth may become sparse and stretched. Keep it out of strong direct sun, which can scorch the foliage.

Water when the top inch of mix feels dry. Soak the pot thoroughly, then let the extra water drain away. Water less often during slower winter growth, and never leave the pot standing in water.

Use a moisture-retentive mix with plenty of air around the roots. Houseplant mix amended with fine bark and perlite works well. A drainage hole is essential.

Keep it between 65 and 80°F and away from cold drafts or hot vents. It can handle ordinary room temperatures, but growth slows below 59°F.

Average household humidity is usually enough. Moderate humidity supports softer leaf edges and steady growth, so use a humidifier if winter air is very dry.

Yellow leaves and soft stems often point to wet roots. Long gaps between leaves usually mean the plant needs more light. Brown tips can follow very dry air, missed watering, or mineral buildup. Watch for aphids, spider mites, mealybugs, and scale. To propagate it, cut below a node and root that section in water or moist mix.
