The ‘Strawberry Star Caladium’ (Caladium bicolor) is admired for its striking foliage. Its leaves display pale green to silvery tones, accented by deep green veins and distinct strawberry pink blotches or speckles. This unique variegation ensures no two leaves are exactly alike. Also known as ‘Angel Wings’, these caladiums add vibrant color and texture to indoor and outdoor garden displays.
Strawberry Star Caladium Care
Light Requirements
Direct sunlight, especially during harsh afternoon hours, can scorch delicate leaves and fade their vibrant colors. Insufficient light may result in less intense leaf coloration and leggy growth. Indoors, place the plant near an eastern or northern window, or a few feet back from a south-facing window. Outdoors, partial to full shade is preferred, particularly morning sun in warmer climates.
Watering Needs
Maintain consistent soil moisture, but avoid overwatering to prevent tuber rot. Allow the top inch of soil to dry out before watering again. Under-watering causes leaves to wilt and become dry. Excessive watering leads to soft, brown leaves and root issues. Pots with adequate drainage holes ensure proper water flow and prevent water accumulation around tubers.
Soil and Potting
This caladium requires a well-draining, fertile soil mix rich in organic matter. A slightly acidic pH (5.5-6.5) is optimal. Suitable components include peat moss, perlite, coco humus, and sphagnum moss, which enhance drainage while retaining moisture. Avoid dense soils that hold too much water, as this impedes root development. Ensure the pot has sufficient drainage holes.
Temperature and Humidity
‘Strawberry Star Caladium’ thrives in warm conditions, with daytime temperatures ideally ranging from 65-80°F (18-27°C). Nighttime temperatures should consistently remain above 60°F (15°C), as these plants are not frost-hardy and are sensitive to cold. High humidity levels benefit their growth. To increase humidity, place the pot on a pebble tray filled with water, use a room humidifier, or mist frequently. Position the plant away from drafty windows or heating vents to maintain a stable, warm, and humid environment.
Fertilization
Fertilize ‘Strawberry Star Caladium’ during its active growing season (spring through late summer). A balanced liquid fertilizer (e.g., 10-10-10 or 20-20-20) or a slow-release granular option is suitable. For container-grown plants, apply a diluted solution every 2-4 weeks. Avoid over-fertilization, which can cause root burn and yellow or brown leaves. Reduce or cease fertilization as the plant prepares for dormancy in late summer.
Planting and Dormancy
Plant ‘Strawberry Star Caladium’ tubers in late spring or early summer, after the last frost and when soil temperatures are consistently above 70°F (21°C). Place tubers 1.5 to 2 inches deep with the “eyes” or buds facing upwards. In garden beds, space tubers 8-12 inches apart; for potted plants, choose a container about twice the tuber’s size. New foliage emerges within a few weeks.
‘Strawberry Star Caladium’ enters dormancy in fall and winter as temperatures cool. Foliage will yellow and die back. Gradually reduce watering as leaves decline, allowing the soil to dry completely. Once foliage has withered, carefully dig up tubers, air-dry for 5-7 days, and store in a dark, dry, well-ventilated location above 50°F (10°C). Alternatively, dormant tubers can remain in their pots with dry soil until spring, when watering resumes to encourage new growth.
Troubleshooting Common Problems
Several issues can affect ‘Strawberry Star Caladium’ health, often indicated by changes in its foliage. Yellowing leaves signal overwatering, underwatering, or nutrient deficiency. Address this by reviewing watering consistency and ensuring regular fertilization during the growing season.
Browning leaf tips or edges indicate low humidity, insufficient watering, or fertilizer salt accumulation. Increase humidity through misting or pebble trays, adjust watering, and properly dilute fertilizer. Flushing the soil with water helps remove excess fertilizer salts.
Soft, brown leaves indicate overwatering or cold temperatures. Allow the soil to dry more thoroughly between waterings and maintain a warm, consistent environment.
Stunted growth or smaller leaves can stem from inadequate light, insufficient nutrients, or a young tuber. Provide bright, indirect light and consistent fertilization for robust growth, as mature tubers yield larger leaves.
Faded leaf colors are often due to excessive direct sunlight. Move the plant to a shadier location with bright, indirect light to restore its vibrant hues.
