About Caladium

Caladiums are tropical plants known for their multi-colored foliage, featuring green, white, red, and pink shades.

As tuberous tropical perennials, these eye-catching plants are commonly grown indoors and outdoors to add color to gardens and homes.

For light requirements, caladium plants prefer indirect light or moderate shade indoors, with the narrower-leaved varieties able to withstand more sun.

To ensure healthy growth, provide well-drained but moist soil rich in organic matter such as mushroom compost or chopped leaves.

Slightly acidic soil is ideal for caladiums, and regular watering will help maintain the desired moisture levels.

Remember that when grown outdoors, caladiums typically reach a height of 12 to 30 inches and a spread of 12 to 24 inches, depending on the variety.

Growing Caladium

To grow caladiums successfully indoors and outdoors, you must provide them with the right conditions.

Choose a location with indirect light as they prefer moderate shade indoors; however, caladiums with narrower leaves can withstand more sun.

Ensure you're in USDA hardiness zones 3 to 10, as these tropical perennials originally come from South America and require specific growing conditions.

Start by ensuring the soil temperature is at least 70°F (21°C), as caladium bulbs will only begin growing at this temperature.

Avoid areas where frost may occur, as caladiums will die if the temperature falls too low.

Amend your garden soil with organic matter like mushroom compost or chopped leaves, or use high-quality potting soil for containers.

Finally, caladiums need well-drained yet moist and slightly acidic soil for optimal growth.

Caring for Caladium Plant

Sun and Temperature

Caladiums thrive in indirect light or moderate shade indoors. They can handle more sun when their leaves are narrower.

Ensure you maintain a consistent temperature range between 70-85°F during the day and above 60°F at night.

Water and Humidity

Keep the soil consistently moist but not soggy, watering your Caladium when the top inch of soil feels dry.

These tropical plants enjoy high humidity, so you can increase humidity around your Caladium by placing it on a tray with wet pebbles or using a humidifier.


Caladiums prefer a well-draining, peat-based potting mix. Mix equal parts of peat moss, compost, and perlite to create a suitable planting medium.

This blend will provide the right balance of moisture retention and aeration for your plant's roots.


Feed your Caladium with a liquid houseplant fertilizer diluted to half the recommended strength once a month during the spring and summer. Always apply the fertilizer to damp soil, not dry.


Caladiums may need repotting when they outgrow their current containers or when their dormant period ends.

Choose a pot one size larger than the original and use a peat-based soil mix for the best results.

Pruning and Propagation

Remove any yellow or brown leaves to keep your Caladium looking its best. Propagate your Caladium by dividing the tubers during the dormant season, ensuring each division has an "eye" or growing point.

Plant the divided tubers in pots with a well-draining soil mix, and maintain high humidity and warm temperatures to promote growth.

Troubleshooting Plant Problems

Growing Problems

Caladiums require well-drained soil rich in organic matter for optimal growth.

If your plant is not growing well, check the soil texture and ensure it falls within the ideal temperature range of 60-90°F (15-32°C).

Additionally, avoid exposing your plants to direct sun suddenly as it may cause sunburn to their vibrant leaves, especially during the growing season.

Instead, provide them with indirect light or moderate shade.

Pests and Diseases

Pests such as caterpillars, aphids, mealybugs, and mites may afflict your Caladium plants.

To treat these pests, use insecticidal soap or other appropriate measures.

However, remember that Caladiums are toxic, so take precautions while handling them.

Root rot can also be an issue if the soil is not well-drained, so ensure proper drainage to prevent this disease.

Companion Planting

Companion planting your Caladiums with other perennials can enhance your garden's visual appeal and create a colorful, vibrant display.

Choose plants with contrasting leaf shapes and textures to create a visually stunning display, such as ferns or hostas.

These companions can also protect your Caladiums from direct sun exposure by providing partial shade outdoors.


Growing Caladiums can be a rewarding endeavor with their vibrant and colorful leaves.

To ensure a healthy plant, provide indirect light or moderate shade indoors and maintain temperatures around 70°F (21°C) or higher.

When planting, choose well-draining soil and place the tubers in the ground with their eyes facing up.

Regularly water your Caladiums, keeping the soil consistently moist.

By following these care tips, you can enjoy the beauty of Caladiums in your home or garden.
