To save elephant ears for another season, first decide whether to overwinter a living plant or store dormant underground parts. These need different conditions. Identify the species or cultivar and confirm that it has a storage organ suitable for dormant storage before cutting it back.
Some young elephant ears have no substantial “bulb” to lift. Keeping such a plant growing indoors may be the better option. Do not assume every plant sold as Alocasia or Colocasia can be dried and stored in the same way.
Option 1: Bring a living plant indoors
Move plants intended as houseplants inside before cold damages them. Inspect for pests first and place them in a warm, bright location suited to the variety. The Wisconsin Extension elephant ear guide distinguishes keeping plants indoors from saving established storage organs.
Check moisture through winter and adjust watering to the plant’s growth and indoor conditions. A plant using less water should not receive the same amount on the same schedule as it did outdoors in summer. Provide drainage; keeping a plant alive is not the same as leaving its roots in standing water.
Option 2: Lift suitable bulbs or tubers
Plan the lifting date around the cultivar and your weather, before the underground parts freeze. Some storage methods allow a light frost to damage the foliage first, but do not wait for a hard freeze to reach the root zone. Leave enough time to handle and dry the material before storage.
Dig outside the clump and lift carefully, widening the excavation if needed rather than forcing a tool through the storage organ. Label the variety while you can still identify it. Remove loose soil and assess for damaged or decaying material before packing.
Allow surface moisture to dry in a sheltered, ventilated place. Do not seal wet material in a bag or assume that exactly one week of drying is correct regardless of conditions. Follow the supplier’s method for the plant you have.
Pack and check through winter
Wisconsin Extension’s tender-bulb storage guide includes storage in a packing medium and regular inspection for elephant ears. Use a frost-free storage location with the temperature recommended for your variety. An unheated garage is unsuitable if it freezes.
Keep labels with the stored material and make it easy to inspect. Check at least monthly for soft areas, mold, excessive shriveling or pests. Separate deteriorating material promptly and seek advice if you are unsure whether it can be saved. Do not apply a generic “organic pest control” product without identifying a pest and checking the label for the intended use.
The practical balance is to avoid wet, decaying storage without allowing the plant material to become severely desiccated. Check the actual storage conditions rather than adding water or changing packing material by habit.
Restart when warmth returns
Inspect the stored material before potting it up. Use the planting instructions for the cultivar and introduce actively growing plants gradually to outdoor conditions after frost danger has passed. See when to plant elephant ear bulbs for spring timing.
Record which storage method and location worked for each variety. Successful storage is not guaranteed, especially with damaged material.
