Caring for Your Caladiums
SUNLIGHT: All caladiums grow well in part shade (4-6 hours of sun). However, some varieties can tolerate full sun (6+ hours) in most parts of the country and others can tolerate full shade (<4 hours). The plant label will tell you how much sun the variety you select can handle.
WATERING: When you first plant your caladiums, keep the soil moist but not soggy. Keep an eye on those growing in full sun as they soil will dry out more quickly there. Once the plants are rooted in and flourishing in your garden, they will only need average amounts of water. Early morning is the best time to water caladiums.
HEAT: Caladiums are tropical plants that love the heat, even in southern climates. Their most active growth occurs during the warmest part of the season. That’s why it is important to wait to put them outside until the air temperatures are consistently at least 60°F and the soil temperature is at least 65°F. Caladiums can get stunted or may even stop growing completely if they are moved outside when it is too cool.
FEEDING: Caladiums don’t need as much fertilizer to stay happy compared to “hungry” flowers like petunias. When you plant them, mix some Proven Winners Premium continuous release plant food into the soil. Follow up with our water soluble plant food once per month.
PESTS: Caladiums are generally considered to be quite pest and disease resistant. Most problems that occur are the result of overwatering which can cause the bulbs to rot, too much sun or too much fertilizer. Though caladiums are considered to be moderately resistant to deer and rabbit browsing, they may nibble the foliage if there is no other suitable food source nearby.
