Elephant ear plants are prized for their dramatic, oversized leaves. Transplanting is necessary when the plant has outgrown its current space, requires division, or needs to be relocated indoors to survive winter temperatures. Safe relocation requires careful planning and execution to protect the plant’s primary storage structure, the tuber or rhizome, and ensure its successful establishment in the new environment.
Preparing for the Move
The ideal window for relocating an actively growing elephant ear is during late spring or early summer, once the soil temperature is consistently at least 65°F. Transplanting during this period of active growth allows the plant to quickly establish new feeder roots before the stress of intense summer heat. Moving the plant on an overcast day or in the early morning or evening can also help reduce immediate stress from sun and heat exposure.
Selecting the new location depends on the species, as Colocasia generally tolerate more sun, while Alocasia often prefer filtered light. The new site must offer rich, well-drained soil that can be kept consistently moist. Elephant ears are heavy feeders to support their large foliage.
Before digging, the receiving hole should be prepared to minimize the time the roots are exposed to the air. Dig a hole that is approximately twice as wide as the current root ball but no deeper. Placing the excavated soil nearby allows for easy backfilling, and amending this soil with compost improves drainage and nutrient availability for the newly settled plant.
Safe Excavation and Handling of the Tuber
The physical process of lifting the plant must be executed with precision to avoid damaging the subterranean tuber. Begin by using a sharp shovel or spade to cut a circle into the soil a minimum of 6 to 12 inches away from the main stem. This generous distance helps ensure that the majority of the fibrous feeder roots and the main tuber are contained within the root ball you are lifting.
Once the initial circle is cut, the shovel should be driven underneath the root mass to sever the deep anchor roots. Gently rocking the plant and using the shovel as a lever helps to loosen the entire mass from the surrounding soil. For particularly large or mature plants, this undercutting process may need to be repeated from several angles.
The entire root ball, including the tuber or rhizome, must be lifted gently and placed on a tarp or into a wheelbarrow for transport. Inspect the main tuber for any signs of damage, soft spots, or rot, which will appear as dark, mushy areas. Remove any loose or excess soil and trim away severely damaged or diseased roots using clean, sharp shears to prevent the spread of pathogens.
Replanting and Immediate Aftercare
Position the elephant ear in the center of the hole, ensuring the top of the root ball is level with or slightly below the surrounding soil line, matching its previous planting depth. For many tuberous varieties, the top of the bulb or corm should sit about one inch beneath the soil surface. Backfill the hole with the amended soil, lightly tamping it down to remove large air pockets.
Immediately after planting, a deep and thorough watering is necessary to settle the soil around the roots and initiate the re-establishment process. This initial soaking helps reduce transplant shock and hydrate the plant’s tissues. Once the water has fully drained, apply a layer of organic mulch, such as shredded bark or straw, around the base of the plant, keeping it a few inches away from the stem. Mulch helps regulate soil temperature and conserves moisture, which is critical for root development.
The plant may exhibit temporary wilting, which is a common sign of transplant shock. If wilting is severe or persistent, pruning one or two of the oldest or largest leaves can reduce the water demand on the plant. For the first two to three weeks, maintain a vigilant watering schedule, keeping the soil consistently moist but never saturated to prevent root rot. This consistent moisture encourages the rapid generation of new fine roots.
