Planting Tips for Elephant Ears

Elephant Ears (Colocasia Esculenta)
For outdoor landscaping

Elephant Ears should be planted in spring after danger from frost has passed. They thrive in sun but prefer partial shade. The soil should be well drained and high in organic matter. Loosen soil to 8” deep. If soil is hard, mix in peat moss, humus, or compost. For best effect, use as a background or border plant. Plant bulb, pointed end up, so that 2” of soil remains above the bulb. Space 18 – 24” apart. Cover with soil and gently firm around bulbs. Water well after planting and keep moist during dry periods.

For container growing

Regular Elephant Ear bulbs have a fast crop time of 6 – 8 weeks. Bottom heat, when available, may be used to speed up the growing process. The plant prefers a moist, warm environment but will stretch under low light levels. Growth regulators such as Bonzi (8ppm) or B-9 (2500ppm) are helpful to avoid stretching and to tone up the plant as the main petiole is strengthened.

Upright Elephant Ears (Alocasia Macrorrhiza)

For Indoor and Outdoor Landscaping

These increasingly popular bulbs, which produce huge upward pointed glossy green leaves provide a cool tropical look in any landscape setting, on a patio, or as a striking centerpiece in a combination planter with caladiums, coleus, or any other bedding plant. They sprout quickly in a moist and warm environment and only take approximate 8 weeks to get to a saleable stage.

Although a tropical plant they can survive temperatures of 32 degrees for up to 4 hours. They prefer high nutritional and light levels. Growth regulators are not applicable for the alocasias as they sprout rapidly from the center petiole. When planting outside, plant the bulbs, with the point up about 3 – 4” under the soil and at least 3 feet apart.

Please Note

Mention of pesticides, growth regulators etc. are by way of illustration only not an endorsement. The label is the law, therefore growers must follow label directions with all regulated materials. Furthermore, different cultivars respond differently to treatments therefore try a small percentage of your crop before applying a treatment to the entire crop. Mention of one product does not preclude the use or benefit of other similar products. Remember read the label and follow it.
