How to care for Elephant's Ear

Difficulty

Elephant's Ear is a low-maintenance plant that requires minimal attention, making it an excellent choice for beginners.

Water

Elephant's Ear should be watered regularly, allowing the soil to dry out between waterings.

Soil

Elephant's Ear loves a well-draining soil. Perlite and vermiculite help with drainage, while coco coir adds organic matter, so a good potting soil mix will have all three. You can improve store-bought soil by adding some perlite to it.

Lighting

Elephant's Ear requires abundant, bright and direct light. Placing it less than one foot from a window is the best way to make sure the plant receives enough light to survive and thrive. Depending on your region, however, the current weather can affect the placement of the plant in your home. For example, in some areas the sun may be too direct and intense, so it's best to place it farther away from the window. You may also need to adjust your placement according to the season as the sunlight can change intensity over the course of the year. If you live in a region with significant temperature fluctuations, such as a desert, you may need to place the plant a bit farther away from the window to avoid extreme heat or cold. With some care and attention, your Elephant's Ear will be sure to bring you many years of beauty and enjoyment.

Toxicity

Elephant's Ear is poisonous if ingested. We suggest keeping this plant out of reach if you have children, cats, or dogs in the home.

Humidity

The Elephant's Ear is not in need of supplementary humidity. Most water is taken in by plants through their roots, thus soil watering is the most efficient way to provide humidity to your plants.

Fertilizer

The Elephant's Ear should be repotted either when it doubles in size or annually, whichever comes first. Providing new potting soil with all the vital nutrients annually is enough to support the growth of the plant, and thus, there is no need for fertilizer. Remember that plants derive their energy from the sun, not fertilizer.

Growth-pattern

The Elephant's Ear is clumping in nature, with new growth originating from the soil in close proximity to the original plant.

Region of origin

Elephant's Ear’s native range is Southeast Asia.

Flower

If you provide your Elephant's Ear with adequate amounts of sunlight and water, it will bloom.
