How to care for elephant ears planted in the backyard
Before you learn how to care for elephant ears, you need to know when the plant them.
Elephant ears should be planted in spring once all threat of frost has passed and the soil has warmed up.
Apply a balanced liquid fertilizer rich in nitrogen every month when they are in growth, and keep the soil moist – they are a good choice for wet, boggy areas of the garden, or as a marginal plant around garden pond ideas.
Do elephant ears need a lot of sun?
Elephant ears need some sun, but not too much. A very important element in how to care for elephant ears is choosing the right spot for them in the backyard when planning out your flower bed ideas. As they make such a dramatic impact, they can be an eye-catching choice for front yard flower bed ideas, too.
As a tropical species, colocasia like lots of warmth, humidity and rich moist soil. They prefer a position in dappled shade, ideally in a sheltered spot.
'Planting elephant ears next to a wall or fence will help to protect the plants from too much sun. The large leaves can also soften the lines and add visual interest to blank walls and boundaries as garden fence ideas,' suggest the experts at Longfield Gardens (opens in new tab).
How often do you water elephant ears?
A very important part of how to care for elephant ears is knowing how often to water them, keeping the soil moist and making sure they don't dry out.
Never allow the soil to dry out completely, which in some climates will mean watering them every day – sometimes several times a day.
'For elephant ears to reach their full size, they need consistent moisture throughout the summer,' explains the Longfield Gardens experts.
How do you care for elephant ears in winter?
The advice on how to care for elephant ears in your garden during winter will differ slightly depending on the hardiness zone in which you live.
'Most colocasia are hardy in zones 8b through 11 – so can be grown outside year round – but require special winter protection when grown in colder regions,' explains gardening expert Melinda Myers (opens in new tab).
Elephants ears will not survive frosts, so if you live in a colder zone, or the UK, dig up the tubers in fall 'just before or after a light frost and allow the tubers to dry in a warm, dry location for 1 to 2 weeks,' says Melinda.
In marginally hardy areas – zones 7 to 11 – mulch elephant ears in winter with shredded leaves and lawn grass to help increase the plant's survival.
'This helps to keep the elephant ears warm and insulated throughout the winter months,' explains Megan Foster, category manager bulbs and perennials at American Meadows (opens in new tab).
First let the stems of the plants die back naturally as cutting them can lead to frost, she advises.
Where tubers have been lifted, these should be replanted and brought back into growth in early spring in a warm place.
Should you cut back elephant ears?
You should cut back elephant ears if you live in a colder region and want to store the tubers over winter, to then plant out again the following spring.
If you know how to overwinter dahlias, then it is the same process for elephant ears. 'They should be dug up before temperatures drop below 40°F,' advise the experts at Longfield Gardens.
'Dig carefully, starting about a foot from the center of the plant. Lift the plant out of the ground and move to a dry place. Once the root ball is dry, cut back the stems,' they add.
Melinda Myers advises to place the tubers in an open container of vermiculite, peat moss or sawdust, to keep them dry and prevent them from rotting, and store in a dry, frost free place, such as a potting shed or garage.
Are elephant ears good container plants?
Elephant ears can make a dramatic impact as a solo plant in a large container.
If you go down the route of growing elephant ears in pots, make sure you water the plants well over summer but then sparingly in winter when they will go dormant.
'Move potted elephant ears indoors before the danger of frost and grow them like a houseplant in a cool, bright location,' advises Melinda Myers.
'Elephant ears are a perfect in pots on shady porches, as deck ideas and other places around your home that are not in full sun. They can also add a tropical touch as a pool patio idea,' say the experts at Longfield Gardens.
How do you care for indoor elephant ears?
To care for indoor elephant ears, you’ll need to keep the plants at temperatures that are above 70 °F (21°C). If it falls below this temperature the plants will go dormant and lose their leaves.
They can certainly be added to the list of best winter house plants. Place them in a bright location so that they get enough light. They can provide exciting and attractive foliage year round given the correct conditions.
Water more sparingly in winter, but do not allow them to dry out completely.
Following the steps above should ensure that you have an elephant ears to enjoy year after year.
