Growing Elephant Ears (Colocasia or Alocasia) in pots can add a dramatic touch to your garden or patio. Harvesting and storing their rhizomes properly ensures healthy growth year after year. This guide provides step-by-step instructions for successful harvesting and storage.
Understanding Elephant Ears Rhizomes
Elephant Ears produce large, tuberous rhizomes that store nutrients for the plant. These rhizomes develop underground and can be harvested once the plant’s foliage begins to die back in the fall. Proper handling of rhizomes is essential to prevent rot and damage.
When to Harvest Rhizomes
The best time to harvest is in late fall after the foliage has yellowed and died back naturally. Avoid harvesting during wet or rainy periods to prevent rot. Wait until the plant is fully dormant for optimal results.
Signs of Readiness
- Foliage has turned yellow or brown
- Plant appears to be withering
- Soil is dry and easy to work with
Harvesting the Rhizomes
Carefully dig around the base of the plant using a garden fork or spade. Gently lift the rhizome from the soil, avoiding cuts or bruises. Remove excess soil by brushing it off or rinsing with water. Inspect the rhizome for any signs of rot or damage.
Cleaning and Preparing
After harvesting, clean the rhizome thoroughly. Cut away any damaged or soft sections with sterilized pruning shears. Allow the rhizome to dry in a warm, well-ventilated area for a few days to prevent mold during storage.
Storing Elephant Ears Rhizomes
Proper storage is crucial for overwintering Elephant Ears in pots. Store rhizomes in a cool, dark, and dry location to prevent sprouting or rotting. The ideal temperature range is between 50-60°F (10-15°C).
Storage Methods
- In Sand or Sawdust: Place the rhizomes in a container filled with dry sand or sawdust, ensuring they are not touching each other.
- In Paper Bags: Wrap each rhizome in newspaper or paper towels and store in a paper bag in a cool, dark place.
- In a Cardboard Box: Arrange the rhizomes in a box with dry material to absorb moisture.
Additional Tips
- Label your stored rhizomes to keep track of varieties.
- Check periodically for signs of mold or rot and remove affected rhizomes immediately.
- Replant the rhizomes in spring after the danger of frost has passed.
With proper harvesting and storage, your Elephant Ears can thrive year after year, providing bold foliage and stunning landscape accents. Happy gardening!
