Elephant ear plants, which include both Colocasia and Alocasia species, bring a touch of the tropics to gardens and interiors with their large, heart-shaped leaves. These perennials thrive well in the warmer climates of USDA Hardiness Zones 8 to 11. In regions that experience colder winter months, however, elephant ear bulbs require special care to endure the off-season. Storing elephant ear bulbs during colder weather ensures that these tropical plants can dazzle in your garden year after year.

Elephant ears stored in a cool, dark place with dry soil

I find that the storage process begins with the first frost, heralding the elephant ears’ dormancy period. After the foliage has yellowed and died back, I carefully unearth the bulbs, taking care not to damage them with my spade. Thoroughly cleaning the bulbs of dirt and allowing them to dry prevents decay, preparing them for their winter resting phase.

Once dry, I place the bulbs in a cool, well-ventilated place protected from freezing temperatures. Storing them in peat moss, sawdust, or wrapped in newspaper aids in keeping them dry throughout winter. My routine check every few weeks helps detect any signs of rot or disease early on, ensuring my elephant ears remain safe until spring. When warmer temperatures return, these bulbs can be replanted, gracing gardens with their striking foliage once more.

Preparing to Overwinter Elephant Ears

When temperatures drop, it’s critical to prepare elephant ear bulbs for overwintering to ensure their survival and health for the next growing season.

Identifying the Right Time

💥 Quick Answer

My elephant ear bulbs must be harvested before the first frost hits, as freezing temperatures can damage them.

I commence the harvest process when the foliage begins to yellow, which usually correlates with the cooling weather of late summer or early autumn. The exact timing is essential; I refer to the local last frost date to schedule the harvest. If I expect an early frost, I plan to harvest earlier to prevent any potential damage.

Harvest and Cleaning Process

I take care to harvest elephant ear bulbs correctly to preserve their viability:

  1. I use a shovel to gently dig around the plant, careful not to cut into the bulbs.
  2. Once loose, I lift the bulbs from the ground and shake off excess soil.
  3. If clumps of dirt or debris refuse to budge, I spray them with water and gently brush the bulbs clean.

💥 Important: Any remaining soil left on the bulbs may harbor pests or diseases; therefore, a thorough cleaning is crucial.

After the bulbs are harvested and cleaned, I allow them to dry in a well-ventilated space. I place them out of direct sunlight and ensure they are not touching each other to prevent rot during the drying phase. This also facilitates good air circulation around each bulb. It typically takes about a week for the bulbs to dry properly. During this period, I vigilantly check for any signs of pests or diseases.

Storing Elephant Ear Bulbs Properly

After the growing season, I make sure to store my elephant ear bulbs correctly to prevent rot and ensure they can be replanted next year. The storage location and conditions are crucial to maintain the viability of the bulbs.

Selecting the Ideal Storage Location

As someone who has had success with storing bulbs, I’ve learned the importance of choosing the right location. The best storage areas provide a consistent environment and can include a garage, basement, or crawl space, as long as they meet the necessary conditions.

I look for a place that is:

– Dry, to prevent mold and rot.
– Cool, but not freezing, to mimic the bulbs’ dormant state.
– Well-ventilated, to ensure moisture from the bulbs can evaporate.

💥 Key Point: A consistent temperature between 45-55°F (7-13°C) and good air circulation are the most critical aspects of a good storage location for elephant ear bulbs.

Ensuring Optimal Conditions

To protect the bulbs from extremes, I focus on maintaining optimal humidity and temperature. I also take measures against pests and moisture that can cause the bulbs to rot.

My steps to ensure these conditions include:
  • Wrapping each bulb in a paper bag or newspaper, which assists in keeping them dry and insulated.
  • Using materials such as peat moss or sawdust to provide extra insulation and moisture control around the bulbs.
⚠️ Caution:

I avoid using plastic as it can trap moisture, leading to rot. Checking the bulbs for signs of spoilage or drying every few weeks is also part of my routine.

Caring for Elephant Ears during Winter

Elephant ears require special care during winter to ensure they survive the freezing temperatures and sprout again in spring. I focus on providing proper insulation and creating the right environment, which are crucial for the overwintering process.

Proper Insulation and Protection

Elephant ears, or plants from the Colocasia, Alocasia, Xanthosoma, and Caladium genera, are not cold-hardy and must be shielded from frost. In regions where the ground freezes, the bulbs, also known as tubers, should be dug up before the first frost. For plants in boggy areas or ones grown in containers, ensure they are moved to a frost-free location. Here, I’m sharing a concise guide on how to protect the bulbs:

Step-by-Step Bulb Protection:
  1. Cut back the foliage to 6 inches above the bulb.
  2. Gently dig up the bulbs, avoiding damage.
  3. Remove excess soil and let the bulbs dry.
  4. Store bulbs in a dry, frost-free area at 45-55°F (7-13°C).

Maintaining the Right Environment

Over the winter, I maintain a well-drained, moist soil medium for any elephant ears stored in pots. Well-draining soil prevents water from pooling and causing rot. For bulbs stored outside of soil, humidity must be monitored to remain around 60-70%, with temperatures between 45-55°F (7-13°C). Below, find a table I created to highlight the environmental needs for overwintering elephant ear bulbs.

Condition Requirement
Temperature 45-55°F (7-13°C)
Humidity 60-70%
Soil for Potted Plants Moist, Well-Draining

I avoid placing bulbs in air-tight plastic bags to prevent moisture buildup, which can lead to rot. Instead, I opt for breathable materials like paper bags or cardboard boxes. With proper care, these tubers will survive the winter and be ready to grow once the warm weather returns.

Common Issues and FAQs

When storing elephant ears, it’s important to watch out for issues like rot and pest infestations. These concerns can affect rhizomes and tubers both during the storage period and after planting. I’ll outline the steps to address these problems, ensuring your elephant ears remain healthy for the next growing season.

Addressing Pest and Disease Concerns

Pests and diseases can endanger stored elephant ears, leading to decay and loss of the plants. Proper inspection and storage practices are crucial. I start by drying the tubers after digging them up, as excess moisture can lead to rot—a common storage issue. After they’re dried, I store them in a cool, dark place and check them periodically for pests. If I encounter pests, a light treatment with an appropriate insecticide can be necessary.

💥 Quick Answer

If your elephant ears’ tubers appear soft or have a foul odor, they may be rotting. Discard any affected parts to prevent spreading.

Before storing, I divide larger clumps into smaller, manageable sections, which is also a great opportunity to propagate new plants. Dividing helps ensure that each piece has enough room to stay dry and pest-free. It’s essential to only divide tubers and rhizomes when they’re dry to prevent introducing pathogens into the cut surfaces.

For those seeking more information, frequently asked questions about storing elephant ears are often addressed in gardening newsletters and articles. In my experience, people often ask if they can store elephant ears like dahlias, and indeed, the techniques are similar. Another common question is whether elephant ears can be grown from seed, which they can, but it’s a less common method compared to propagating through division.

Regularly inspect stored elephant ears. Remove any tubers or rhizomes that show signs of disease or infestation to prevent affecting the others.
