Giant Elephant Ear care guide
Giant Elephant Ears are easy to care for in the right conditions.
Giant Elephant Ear watering
Elephant ears prefer moist soil and do best if they don’t dry out. They are native to the rainforest after all!
How often should I water my Giant Elephant Ear?
Giant elephant ear plants don’t like to dry out, so water them as soon as the soil around them feels dry to the touch.
Can you overwater elephant ears?
Elephant ears love water and it’s very hard to over water them. One culprit however could be clay soil trapping water like a ceramic bowl. Be sure that there is drainage to avoid the bulbs sitting in a pool of water.
Should I mist my elephant ear plant?
Elephant ears love humidity. If you live in a dry place, they will benefit from misting. When we go a while without rain, I like to water our leaves on the mist setting once a week or so!
Giant Elephant Ear lighting needs
Elephant ear plants love sun. They can take full sun or partial sun. We have 4 plants along our fence and the more sun that the plant gets, the larger that it gets!
Will Giant Elephant Ear survive the winter outdoors?
Giant elephant ears are hardy in zones 8-11. In zones 8-9 they will die back and regrow in the spring. In zones 10-11, they are usually evergreen.
If your plant dies back over the winter, expect it to start growing back in when temperatures are consistently around the clock at least 65 degrees.
If you live in a colder area, you can dig your bulbs up and bring them indoors for the winter.
Can I keep Giant Elephant Ear indoors?
Giant elephant ears could survive in a sunny, warm window indoors with enough humidity. But remember how huge they are! They need a lot of space.
Giant Elephant Ear soil + potting
Elephant ears like well draining soil. Elephant ears like organic material such as compost or manure mixed in with their soil.
How do you plant elephant ear bulbs?
You plant giant elephant ear bulbs with the pointy side facing up! Plant them 24 inches apart to give the plant space to spread.
Giant Elephant Ear fertilization
Elephant Ears love being fertilized. Apply a general 20-20-20 fertilizer once a month in the warm growing months to help them grow as lush as possible.
Troubleshooting Giant Elephant Ear
Why are my giant elephant ears leaves dying?
It is completely normal for giant elephant ears to drop their older leaves. They grow quickly and when they have too many leaves, let the older ones die off to save energy.
Alocasia macrorrhiza vs colocasia gigantea
These are two very similar looking plants – both are often called giant elephant ears! Typically, alocasia leaves point UP and colocasia leaves flop down a bit more!
How do you propagate giant elephant ears?
Giant elephant ear plants are generally propagated via division. This means, if your plant is looking huge, you can gently separate it by the bulb into two or more pieces and plant them separately!
