Signs It’s Time To Dig Up Elephant Ears

You will know it’s the perfect time to dig up elephant ears (aka colocasia) when the weather starts to turn and the leaves on your trees turn brown.

If you don’t have time to dig up your plants, don’t worry. It is okay to wait until the first frost but do not go longer than that, as the tuber will die.

While the leaves should be brown when you begin digging up the bulbs, exercise caution when working around the plants. Its leaves have a coating of needle-like calcium oxalate and are often irritating to touch.

How To Harvest And Store Elephant Ear Bulbs

You do, of course, want to transplant your elephant ear bulbs in the spring. Here is how to harvest and store elephant ear bulbs.

  • Start by digging the bulbs out of the soil while avoiding root damage. If you damage the bulb, it will likely rot over the winter.
  • With that in mind, dig around one foot away from the plant’s base, and lift both the plant and bulb from the soil.
  • With the bulbs safely removed from the soil, it is time to clean the elephant ears. You can gently rinse them with cool, but not cold, water. Do not scrub the elephant ear bulbs.
  • During the cleaning process, you may cut and remove the remaining foliage—carefully!
  • Once the bulbs are clean, you must dry them. For around one week, keep your elephant ear bulbs in a warm, dark spot with good circulation.
  • Once dried, wrap your elephant ear bulbs in paper and store them in a cool, dry place.
  • If keeping them until spring, check on your bulbs every few weeks to ensure no pests break in or rot occurs. If you do find pests, treat the bulbs using an insecticide. If corrosion occurs, throw the bulbs out to ensure it does not spread.

Why Can You Regrow Elephant Ears?

Unlike many other plants, which only survive for a year or two when transplanted, elephant ears may grow year after year. Why? They grow from tubers covered in buds that sprout new growth when transplanted into the soil and fed.

It is these tubers you want to protect when digging up elephant ears before winter.

Is It Worth Digging Up Elephant Ears?

Even for someone who genuinely enjoys gardening, digging up elephant ears year after year, cleaning and drying them, then storing them someplace cool becomes a chore.

So is it worth it to dig up elephant ears for the spring? Yes!

When you dig up the bulbs—without damaging them—you preserve the plants for the next season. Who doesn’t want to enjoy Black Magic Elephant Ears in the spring!

Types Of Bulbs

Alongside the beautiful elephant ears, other types of bulbs need the same kind of care and attention. These include:

  • Tuberous Begonias – Gradually improve and grow for around eight years, with proper care, then perish.
  • Gladiolus Bulbs – Sprouts and flowers for two to three years, then begins to decline. You will want to dig up gladiola before a hard frost occurs – usually in October.
  • Dahlia – Dahlias survive best when dug up two weeks after any foliage dies by frost—around mid-November. When storing dahlia, consider placing them in barely dampened peat moss. When it comes time to plan, divide the bulbs into clumps.
  • Elephant Ears – If you successfully dig up, treat, and store elephant ears, they only get better with time. You’ll have them for years to come.

You may decide to dig up and replant your elephant ears year after year (remember: they only get better with time). Or you may choose to buy new tubers and bulbs for the coming season.
