Sun, Soil, and Water Requirements for Growing Elephant Ears:
Sun: Elephant ears prefer partial shade to full shade. They can tolerate some direct sunlight in the morning or late afternoon, but direct sunlight during the hottest part of the day can scorch their leaves.
Soil: Elephant ears prefer rich, moist soil that is well-drained. They do not tolerate standing water, but they do require consistent moisture to thrive. Adding organic matter to the soil can help improve drainage and moisture retention.
Water: Elephant ears require regular watering to keep their soil consistently moist. They can tolerate brief periods of dryness, but they will not thrive in consistently dry soil. During hot and dry weather, it may be necessary to water them more frequently.
It's important to note that elephant ears are not frost-tolerant and should be brought indoors for the winter in colder climates. Additionally, elephant ears can benefit from regular fertilization during the growing season to support their lush foliage. By providing the right sun, soil, and water conditions, you can enjoy the dramatic and exotic appearance of elephant ears in your garden or indoor space.
