What Are Caladiums?
Caladiums (Caladium bicolor) are tropical plants from South America, famous for their large, arrowhead-shaped leaves. Unlike most plants, they’re grown for their foliage, not flowers, which makes them perfect for adding a splash of color to shady spots. They’re perennials in warm climates but can be treated as annuals or brought indoors in cooler areas like much of the USA.
Why Are Caladiums So Popular?
Why do gardeners adore caladiums? Here’s why:
- Gorgeous Leaves: From bold reds to soft whites, their colors are unbeatable.
- Versatile: They work indoors in pots or outdoors in gardens.
- Shade-Friendly: They thrive in low light, unlike many colorful plants.
- Easygoing: With the right care, they’re low fuss.
I love how they spark conversations—people always ask about mine when they visit!
Caladium Plant Care Basics
Let’s start with the essentials. These apply whether you’re growing caladiums indoors or out.
Light Requirements
Caladiums love bright, indirect light. Too much sun can burn their leaves, but they don’t mind a little morning sun in cooler spots.
- Indoors: Set them near a window with filtered light—like north or east-facing.
- Outdoors: Plant them under trees or in partial shade.
Temperature and Humidity
Being tropical, caladiums crave warmth and moisture.
- Temperature: 70°F to 85°F (21°C to 29°C) is their sweet spot. Below 60°F (15°C), they’ll nap.
- Humidity: They adore high humidity. Indoors, I use a humidifier in winter to keep them happy.
Once, I left a caladium near a chilly vent—big mistake. The leaves drooped fast!
Soil Preferences
Good soil is key. Caladiums need it rich and well-draining.
- Indoors: A potting mix with peat moss or perlite works great.
- Outdoors: Add compost to garden soil for nutrients and drainage.
Watering Needs
Caladium plant care watering can trip people up. They like moist soil, not soggy.
- How Often: Water when the top inch of soil dries out—every few days in heat, weekly in cool weather.
- Overwatering Signs: Yellow leaves or mushy stems.
- Underwatering Signs: Wilting or curling leaves.
I stick my finger in the soil to check—works every time.
Caring for Caladiums Indoors

Choosing the Right Spot
Pick a place with bright, indirect light. Avoid heaters or AC vents—I learned that the hard way when one wilted fast.
Pot and Soil
- Pot: A size just bigger than the roots, with drainage holes.
- Soil: I mix potting soil with perlite for airflow.
Watering and Feeding
- Watering: Keep soil moist but not soaked.
- Fertilizing: Every 4-6 weeks in spring and summer with a diluted 10-10-10 fertilizer.
Indoor Troubleshooting
- Dry Air: Mist leaves or use a pebble tray with water.
- Pests: Spider mites can sneak in. I zap them with neem oil.
One winter, I caught spider mites early and saved my plant—phew!

Light and Shade

Watering and Mulching

- Mulching: A 2-inch layer keeps moisture in and weeds out.
