In this guide, we’ll cover everything you need to know about growing and caring for caladiums, from choosing the right varieties to preventing pests and diseases.
Choosing Caladium Varieties
There are many different cultivars of caladiums to choose from, each with its own unique colors and patterns. Some popular varieties include:

When choosing a caladium variety, consider the color and pattern of the leaves and how they will complement the other plants in your home or garden. You should also think about the size of the plant and how much space you have available.
Growing Caladiums
Caladiums prefer to grow in warm, humid environments with filtered sunlight. They can be grown outdoors in USDA hardiness zones 9-11, but they can also be grown indoors in pots or containers.
Planting Caladiums
- Outdoors: Choose a spot with rich, well-draining soil and plenty of organic matter. Plant the caladium bulbs with the top facing up and covered by about 4 inches of soil. Water thoroughly and keep the soil moist but not waterlogged.
- Indoors: Plant caladium bulbs in a pot or container with drainage holes. Use a well-draining potting mix and plant the bulbs with the top facing up and covered by about 2 inches of soil. Water thoroughly and keep the soil moist but not waterlogged.
Caring for Caladiums
Caladiums are relatively easy to care for. Here are a few tips:
- Watering: Caladiums need regular watering, especially during hot, dry weather. Water the plants deeply and allow the soil to dry out slightly between waterings. Avoid overwatering, as this can lead to root rot.
- Fertilizing: Fertilize caladiums once a month with a balanced, water-soluble fertilizer. This will help promote healthy growth and flowering.
- Light: Caladiums prefer to grow in filtered sunlight or partial shade. Too much direct sunlight can scorch the leaves and dry them out.
- Temperature: Caladiums are tropical plants and prefer warm temperatures. They can tolerate temperatures as low as 55 degrees Fahrenheit, but they will grow best in temperatures between 70 and 85 degrees Fahrenheit.
- Humidity: Caladiums prefer high humidity. If you’re growing caladiums indoors, you can increase the humidity by misting the leaves regularly or placing the plant on a pebble tray filled with water.
Pests and Diseases
Caladiums are susceptible to a few pests and diseases, including:
- Red spider mites: These tiny pests can cause the leaves to turn yellow and drop off. To prevent spider mites, keep the plants well-watered and mist the leaves regularly.
- Mealybugs: These small, white insects can suck the sap from the leaves and stems. To control mealybugs, use a cotton swab dipped in rubbing alcohol to remove them from the plant.
- Fungal leaf spot: This disease can cause brown spots to form on the leaves. To prevent fungal leaf spot, avoid overhead watering and make sure the plants have good air circulation.
Conclusion
Caladiums are beautiful and easy-to-grow plants that can add a touch of the tropics to any home or garden. By following the tips in this guide, you can keep your caladiums healthy and thriving for years to come.
