Growing Elephant’s Ear

As mentioned before, the Elephant’s Ear will thrive in partial shade. Thus, it is important, especially during the warm season, not to expose your Elephant’s Ear plant to direct, bright sunlight. Also, if you plant it outdoors, look for the area in your garden that only gets partial sunlight throughout the day.

It is essential to consider the temperatures in your area if you plant your Elephant’s Ear outdoors. The ideal temperatures for these plants are between 65-75°F (18-24°C) during the day and no lower than 60°F (15°C) during the night. If your area’s climate is cooler than that, you’ll have to replant your Elephant’s Ear each year. 

The area where you’ll plant your Elephant’s Ear plant, be it outdoors or indoors, should have rich soil that is moist, but also well-drained. That’s because, like most plants, Elephant’s Ears don’t like wet feet.

Big, green Elephant’s Ear plants are typically easier to grow as they are more tolerant of variable moisture conditions. On the flip side, darker-leaved plants are more susceptible to overwatering, as they prefer to stay dry for many days.

Expect your Elephant’s Ear plant to grow very rapidly, even during a short growing season.

Planting Elephant’s Ear

It is essential to remember that most of Elephant’s Ear plants prefer to be planted in rich, moist soil. Also, they prefer partial shade. So, keep these aspects in mind when you plant them, be it in your garden or in a pot.

If you plan on growing Elephant’s Ear plants outdoors, in your garden, wait for the threat of frost or subzero temperatures to pass.

The Elephant’s Ear bulbs need to be planted at about 2 to 3 inches deep, with the blunt end downwards. If you plant the bulbs indoors, remember to use rich, organic potting soil and to plant them at the same depth. Choose a container that’s at least 18 inches (45 cm) wide and 16 inches (40 cm) deep.

If you later decide to replant the Elephant’s Ear plant outdoors after you’ve kept it indoors in a pot, you need to give it time to adjust to its new environment before you replant it. 

Watering Elephant’s Ear

Most Elephant’s Ear plants thrive in moist soil and prefer humidity. But, remember not to overwater them because these plants don’t like soggy soil. 

It is best to water them in the morning so that the plants stay dry overnight. Also, you should always water the plants from below, near their roots in order to prevent the leaves from getting too wet. However, if you notice that your plant’s leaves become darker, cut back on watering.

During the cold season, you should water your Elephant’s Ear plants less frequently and make sure you allow the soil to become dry between waterings. What’s more, during the cold months, you should also stop fertilizing. However, during the other seasons, you should fertilize your plant once a month. You can use an all-purpose fertilizer, diluted by half.

Propagating Elephant’s Ear

Propagating Elephant’s Ear is a little bit different than how it is with most plants. Unfortunately, the Elephant’s Ear can’t be propagated from cuttings as many plants do. But don’t worry, you can divide the tubers of a healthy parent plant to propagate it.

It is best to propagate the plant during the fall. All you have to do is plant the tubers in pots and store them during the winter to protect them from freezing temperatures. Then, in spring, you can plant them outdoors if you want to have them in your garden. 

For the highest chance of success with propagating Elephant’s Ear, it’s best to wait for the parent plant to go dormant in the fall, and for its leaves to die off. Once your plant has become dormant, you can remove it from its pot or from its in-ground outdoor location. 

Dividing the new tubers during the fall helps as it will put less stress on the parent plant. Why? Because in the cold autumn months, the parent plant isn’t actively growing, so you can separate the new tubers without doing any damage. 

In Conclusion 

Elephant’s Ear plants are perfect for both your indoors and outdoors areas. Whether you want to make your home or your garden look more exotic, these tropical-looking plants are perfect additions to your space. If you love Boho and Jungalow styles, these plants are a must-have. 

As long as you protect them from direct sun exposure and make sure they have a humid and moist place to grow, Elephant’s Ear plants will reward you with their impressive foliage.
