Colocasia ‘Yellow Splash’ is a striking plant for gardens or indoor settings, known for its bold, variegated foliage and tropical ambiance. This cultivar features large, heart-shaped leaves adorned with a vibrant mix of bright green, lime, and yellow splotches and streaks. Its unique, irregular patterns make each leaf distinct, adding exotic beauty and vibrant color to any setting.
Colocasia ‘Yellow Splash’ Care Guide
Colocasia ‘Yellow Splash’ needs specific light conditions for healthy growth and vibrant variegation. These plants thrive in partial shade to full sun. In hot climates, afternoon shade protects leaves from scorching. Indoors, a bright location with filtered sunlight is ideal, as direct sun can cause leaf burn or fade yellow variegation. Insufficient light also diminishes yellow patterns.
Colocasia ‘Yellow Splash’ prefers consistent moisture, making it suitable for areas near water features. The soil should remain evenly moist but never waterlogged to prevent root rot. Water thoroughly when the top inch of soil feels dry. More frequent watering may be needed in warmer or drier conditions.
For ‘Yellow Splash’, use rich, well-draining soil that retains moisture. A good mix includes garden soil, organic compost, and amendments like sand or perlite for drainage and aeration. They prefer a slightly acidic to neutral soil pH (5.5-8). Organic matter enhances soil fertility.
Colocasia ‘Yellow Splash’ thrives in warm temperatures and high humidity. Temperatures between 70°F and 85°F (21°C to 29°C) are ideal; below 50°F (10°C) can cause damage. Maintain high humidity by misting leaves regularly or using a humidifier, especially indoors.
Fertilize ‘Yellow Splash’ regularly during its active growing season. Apply a balanced, water-soluble fertilizer every two to four weeks from spring through summer. As heavy feeders, they benefit from consistent nutrient supply, especially nitrogen for larger, vibrant foliage. Always dilute fertilizers as instructed to avoid over-fertilization.
Plant ‘Yellow Splash’ outdoors after the last frost. They can be grown in the ground or containers. For containers, choose large, sturdy pots with adequate drainage to accommodate their growth and moisture needs. Plant tubers about 4 inches deep with the pointed end facing upwards for proper sprouting.
Overwintering Colocasia ‘Yellow Splash’
In cold winter regions (below 50°F/10°C), ‘Yellow Splash’ requires overwintering as it is not frost-tolerant. Begin after the first light frost or when temperatures consistently fall below 40°F (4°C) and foliage dies back. Cut stems to about 6 inches above ground. Dig up tubers carefully, brush off excess soil, and avoid rinsing. Dry them in a warm, dry place for one to two weeks to prevent rot.
Once dry, store tubers in a cool, dark, frost-free environment (50-60°F/10-15°C). Place them in an open container with a dry medium like vermiculite, peat moss, or sawdust to prevent desiccation. Potted plants can be moved indoors before frost, allowed to go dormant, and watered sparingly through winter.
Propagating Colocasia ‘Yellow Splash’
Propagate ‘Yellow Splash’ by dividing its tubers or rhizomes, as the plant naturally spreads this way. The best time is during the active growing season or when preparing tubers for planting. To propagate, remove the plant from its pot or dig it up, shaking off excess soil to expose the tubers.
Identify individual tubers or rhizome sections, ensuring each has a growth point and part of the rhizome. Use a clean, sharp knife to separate them if needed. Plant each division individually in pots with well-draining, moist potting mix. Plant them at a similar depth, or about 4 inches deep for distinct tubers. Provide warmth and consistent moisture to encourage new growth.
Common Problems and Solutions
Yellowing Leaves
Yellowing leaves on Colocasia ‘Yellow Splash’ often indicate improper watering or nutrient deficiencies. Overwatering, poor drainage, or underwatering can cause leaves to yellow. Ensure soil is consistently moist but not waterlogged, and check drainage. Address nutrient deficiencies with appropriate fertilization.
Fading Variegation
Fading variegation is linked to light exposure. The yellow splashes require adequate, indirect light for vibrancy. Too much direct sun can bleach or fade the yellow; too little light prevents full variegation. Adjust placement to optimize light and preserve leaf patterns.
Pests
Common pests for ‘Yellow Splash’ include spider mites, aphids, and mealybugs. Regularly inspect leaves, especially undersides, for early detection. Manage small infestations by wiping leaves with a damp cloth, applying insecticidal soap, or using neem oil.
Fungal Issues
Fungal issues like leaf blight and root rot can arise from overly wet conditions or poor air circulation. Symptoms include round lesions on leaves or general plant decline. Ensure good air circulation and avoid prolonged wet foliage. Proper watering to prevent waterlogging is also important.
