How to Plant Elephant Ears
Planting elephant ears is easy. You can grow them from bulbs (also called tubers) or from nursery plants.
Step-by-Step Planting Guide
- Choose your location
- Pick a spot with morning sun and afternoon shade. Elephant ears need warmth and humidity.
- Prepare the soil
- Use rich, organic soil. Mix in compost to improve drainage and nutrients.
- Plant the bulb
- Dig a hole 2–4 inches deep. Place the bulb with the pointed side up. Cover with soil and water well.
- Water regularly
- Keep the soil moist, especially in the growing season.
- Fertilize monthly
- Use a balanced fertilizer to help the plant grow bigger and faster.
When to Plant Elephant Ears
Elephant ears are warm-weather plants. Wait until the danger of frost is gone before planting outdoors. In most zones, this is in late spring.
If you live in a cold area, you can start them indoors in pots 4–6 weeks before the last frost.
Growing Elephant Ears Indoors
You can grow elephant ears indoors, but they need the right care.
Tips for Indoor Growth
- Use a large pot with drainage holes

- Mist the leaves to increase humidity
- Rotate the pot for even growth
Indoor elephant ears can grow up to 4 feet tall. They make great focal points in any room.

Common Problems and Solutions
Even though elephant ears are hardy, they can face some issues. Here are common problems and how to fix them:

Do Elephant Ears Come Back Every Year?
That depends on your climate.
- Warm zones (8–11): Elephant ears are perennials and return every year.

If you live in a cold climate, you can save the bulbs to plant again next year.
Storage Steps

- Dig up the bulb and gently shake off the soil
- Let it dry in a cool, dry place for a few days
- Store in a paper bag or box with peat moss
- Keep in a cool, dark place (above 45°F/7°C)
Replant in the spring when the soil warms up.
