Caladiums: The Heart of Jesus Plant
Introduction
Caladiums, also known as elephant ears, are popular plants known for their striking foliage. They come in a wide range of colors and patterns, making them a favorite for both indoor and outdoor gardening.
Types of Caladiums
There are two main types of caladiums: fancy-leaved and strap-leaved. Fancy-leaved caladiums have large, heart-shaped leaves with intricate patterns. Strap-leaved caladiums have long, narrow leaves that are often variegated.
Planting Caladiums
Caladiums can be planted as potted plants or dormant tubers. The best time to plant them is in spring or summer, after the last frost. Plant the tubers 1.5-2 inches deep, with their eyes facing up. Space the plants 4-6 inches apart.
Caladium Care
Light Requirements: Caladiums prefer shade or partial shade. They can tolerate full sun, but their leaves may scorch if they receive too much direct sunlight.
Watering Needs: Caladiums need consistent moisture. Water them regularly, especially during hot, dry weather. Avoid overwatering, as this can lead to root rot.
Temperature & Humidity: Caladiums grow best in warm, humid climates. They prefer temperatures between 70-85 degrees Fahrenheit. If you are growing caladiums indoors, mist them regularly to increase the humidity.
Soil & Compost: Caladiums can grow in a variety of soil types, but they prefer well-draining soil that is rich in organic matter. Amend the soil with compost or manure before planting.
Fertilizer: Caladiums benefit from regular fertilization. Feed them every few weeks with a balanced fertilizer.
Propagation
Caladiums can be propagated by division. To do this, dig up the plant in the fall and divide the tubers into smaller pieces. Each piece should have at least one eye.
Problems, Pests & Diseases
Caladiums are relatively pest-free, but they can be susceptible to certain problems, such as:
- Root rot: This can occur if the plant is overwatered or if the soil is not well-draining.
- Leaf scald: This can occur if the plant receives too much direct sunlight.
- Mealybugs: These small, white insects can feed on the plant’s leaves and stems.
Overwintering Caladiums
In cold climates, caladiums need to be overwintered indoors. Dig up the plants in the fall and cut off the foliage. Store the tubers in a cool, dark place until spring.
