The Heart of Jesus plant, also known as Caladium hortulanum, is famous for its large, heart-shaped leaves, splashed with vibrant pinks, reds, greens, and whites. This striking yet surprisingly easy-to-care-for houseplant brings a bold touch of color to your home—perfect for beginners thanks to its forgiving nature and tolerance of low to moderate light.
Light Requirements
Heart of Jesus thrives best in bright, indirect sunlight. Avoid putting this beauty in direct afternoon rays, which can scorch its delicate leaves. East- or north-facing windows are ideal, or you can set it a few feet from a bright window filtered by sheer curtains. It tolerates lower light but may lose some vibrant color if too dim.
Watering Schedule
Water Heart of Jesus regularly to keep the soil evenly moist—never soggy or bone-dry. Let the top inch of soil dry out between waterings, especially in cooler seasons. Limp leaves typically signal underwatering, while yellowing and mushy stems suggest you’ve gone too far. A humidifier can help keep the air moist, especially in dry climates.
Humidity & Temperature
Caladiums love high humidity (60%+), so steamy bathrooms or kitchens make great homes. Keep the temperature between 65–80°F (18–27°C); anything below 60°F (15°C) can stress the plant. Protect Heart of Jesus from sudden drafts and chilly windows—cold can make leaves wither quickly!
Soil & Potting
Use a light, well-draining potting mix—look for one made for aroids or combine regular potting soil with peat and perlite. Repot Heart of Jesus every spring if roots seem cramped, using a pot with drainage holes to avoid waterlogged roots.
Fertilizing
Feed your Heart of Jesus every 4–6 weeks during spring and summer with a balanced, water-soluble houseplant fertilizer (diluted to half strength). There’s no need to fertilize in the dormant, winter months.
Common Problems & Solutions
Yellowing leaves often mean excess water; let the top of the soil dry out before watering again. Brown edges may signal dry air—mist the plant or increase humidity. Droopy leaves can be thirst, but check soil before watering. Watch for spider mites or aphids; wipe leaves and use insecticidal soap as needed. Remove any fading leaves to keep it tidy.
Extra Tips
Rotate your Heart of Jesus every week for even growth and color. Group with other humidity-loving plants, like ferns or peace lilies, for a lush display. Fun fact: Caladiums “rest” in winter—it’s normal for leaves to die back! Simply reduce watering, and watch for new growth when spring returns.
