Elephant Ears are a popular choice for gardeners seeking large, lush foliage. While they thrive in warm climates, growing them in the North and other cold regions requires special care and attention. With the right strategies, you can enjoy these impressive plants even in cooler weather.
Understanding Elephant Ears
Elephant Ears (genus Colocasia and Alocasia) are tropical plants known for their enormous, decorative leaves. Native to warm, humid environments, they flourish in USDA zones 8-11. In colder regions, they need extra protection and care to survive the winter months.
Choosing the Right Variety
- Colocasia esculenta — The most common variety, suitable for container growing.
- Alocasia species — Known for striking foliage and unique shapes.
- Cold-hardy hybrids — Some cultivars are bred for better cold tolerance.
Planting Tips for Cold Climates
To successfully grow Elephant Ears in the North, start with healthy tubers or rhizomes. Plant them in well-draining soil, ideally in a sheltered location away from harsh winds. Use raised beds or containers to improve drainage and warmth.
Timing
Plant tubers after the last frost date in spring. In northern regions, this typically means planting in late April or early May. For container plants, you can start them indoors earlier to get a head start.
Soil and Watering
Use rich, organic soil with good drainage. Keep the soil consistently moist but not waterlogged. Mulching around the plants helps retain warmth and moisture.
Overwintering Elephant Ears
In cold climates, Elephant Ears cannot survive outdoors year-round. Dig up tubers before the first hard frost and store them indoors in a cool, dry place. Alternatively, leave container plants inside or in a greenhouse during winter.
Storing Tubers
- Carefully dig up the tubers after foliage dies back.
- Brush off excess soil and let them dry for a few days.
- Store in a paper bag or box with peat moss or sand.
- Keep in a cool, dark place at 45-50°F (7-10°C).
Additional Tips for Success
- Use frost covers or row covers during unexpected cold snaps.
- Choose sheltered locations to reduce wind stress.
- Ensure adequate watering during the growing season.
- Fertilize regularly with a balanced fertilizer.
Growing Elephant Ears in cold climates requires effort, but the stunning foliage makes it worthwhile. With proper planning, timing, and winter protection, you can enjoy these tropical giants even in the north.
