Colocasia ‘Mojito’ is a captivating plant known for its dramatic visual appeal. This cultivar of Colocasia esculenta, commonly called Elephant Ear or Taro, features large, heart-shaped leaves with a dark green to black base heavily splashed with vibrant lime-green variegation. Each leaf unfurls with its own distinct pattern, making it a popular choice for adding tropical flair to gardens and indoor spaces.
Essential Care Requirements
Light
Colocasia ‘Mojito’ thrives in bright, indirect light. While it tolerates some morning or late afternoon sun, intense midday sun can scorch its leaves. Insufficient light can diminish the plant’s distinctive variegation and lead to leggy growth. Outdoors, dappled shade or filtered sunlight is ideal; indoors, a bright room with filtered window light is suitable.
Water
This plant requires consistent moisture, reflecting its bog or wetland origins. The soil should remain consistently moist but never waterlogged. Allow the top inch or two of soil to dry slightly before watering, but avoid prolonged drought, which can cause wilting, stunted growth, or dormancy. Good drainage is important; some growers even cultivate ‘Mojito’ in shallow standing water.
Soil
Colocasia ‘Mojito’ prefers a rich, well-draining soil mix that retains moisture. An ideal blend includes potting soil amended with organic compost, peat moss, and perlite or sand to enhance drainage and provide nutrients. Amending the soil with organic matter promotes overall plant health and vigorous growth. For containers, a suitable mix can include topsoil, peat moss, and compost.
Temperature and Humidity
As a tropical plant, Colocasia ‘Mojito’ prefers warm temperatures, ideally between 65°F and 85°F (18°C to 29°C). It is sensitive to cold and requires protection from temperatures below 50°F (10°C). High humidity is also beneficial. To increase humidity, especially indoors, use a pebble tray, group plants, or employ a room humidifier.
Fertilizer
During its active growing season (spring and summer), Colocasia ‘Mojito’ benefits from regular fertilization. Apply a balanced, water-soluble fertilizer every two to four weeks to support lush foliage and robust growth. Reduce or cease fertilization during fall and winter as the plant’s growth naturally slows.
Seasonal Care and Dormancy
Colocasia ‘Mojito’ is a heat-loving, frost-sensitive plant, hardy in USDA Zones 8-10. In cooler winters, it naturally enters dormancy. Gardeners in colder climates have two overwintering options: maintaining active growth indoors or forcing dormancy.
To keep the plant active indoors, provide consistent warmth (above 60°F or 15°C) and bright, indirect light. Reduce watering but keep the soil slightly moist, and maintain humidity. For dormancy, dig up tubers after the first frost, cure them, and store in a cool, dark, dry location above 40-45°F (4-7°C). Store tubers in dry peat moss or wood shavings until spring.
Common Problems and Solutions
Yellowing leaves on Colocasia ‘Mojito’ often indicate overwatering or underwatering, which disrupt nutrient uptake. If new leaves are forming but older ones yellow and die, this can be a natural shedding process, especially for young plants or those in smaller pots. Consistent moisture and proper drainage help.
Crispy or browning leaf edges suggest low humidity or insufficient watering. Increase humidity with misting, pebble trays, or humidifiers, and ensure consistent soil moisture. Soft, floppy leaves may signal overwatering.
Lack of vibrant variegation indicates insufficient light; move the plant to a brighter, indirect light location. Pests like spider mites and aphids appear as tiny specks or webs. Regularly rinse foliage to prevent infestations; use insecticidal soaps or neem oil for severe cases.
Root rot, a fungal issue from waterlogged soil, causes mushy stems or a foul odor. Address watering habits and ensure excellent drainage for prevention.
