How to Grow Elephant's Ear Plants
Elephant's ears are pretty easy to grow as long as you provide them with rich soil and the right amount of sun.
If you're planning on growing indoors, be sure to choose a larger container for your plant to grow into. If planting outdoors, only do so approximately 8 weeks post the last frost.
Cultivating Elephant's Ear
The most common method of cultivation is by means of division. Simply divide the tuber into pieces with a sterilized blade, each with a corn on it. Leave the pieces to dry out for a few days and then plant into soil, blunt end down, to root.
You can consider dipping the end into a rooting hormone. However, these plants tend to re-grow from their tubers pretty quickly.
Planting Elephant's Ear
Before planting, ensure the right temperature and conditions. If it's too cold, your plant may not survive.
When planting, you'll want to:
- Prepare the bed, turning the soil to at least 20 cm deep.
- Use a rake to remove any stones or debris from the soil.
- Compost the soil with rich organic matter.
- Plant your Elephant's ears at least 60 to 120 cm apart.
Once planted, be sure to water semi-regularly until established.
Elephant's Ear Plant Care
These plants require very basic care, provided they receive enough sunlight. It is recommended to water these plants in the mornings, so the soil can dry out before the cool of the night.
You'll want to try to keep water off of the leaves, so watering at the base of the plant is preferable. When it comes to fertiliser, Elephant's ear plants are not heavy feeders and will require very little fertilisation.
If you do fertilise, be sure to use a slow-release, water-soluble fertiliser or supplement your water with a little bit of Epsom salts.
These plants thrive in warmer climates and tropical regions. It is possible to grow Elephant's ears in colder climates. However, you will need to replant them each year to protect them from any frost.
- Cut back a large portion of foliage.
- Dig up the rhizomes leaves overnight to dry out.
- Fill a container with peat moss and leave your plants in a warm, slightly sunny spot.
Alternatively, keep your plants in a pot or container even in the garden, so they can be moved when the winter chill sets in. If growing indoors, fertilise your Elephant ear plant only in the summertime.
Indoors, Elephant's ear plants are also very unlikely to flower. When growing outdoors, you'll want to ensure you keep your Elephant's ear well-watered and the soil well mulched.
Mulching will help to keep the soil nutrient-rich and deter pesky weeds from invading.
Diseases, Pests & Problems
In water-logged soil, these plants can become too prone to leaf spot and root rot. Always take care to ensure the soil is draining adequately. If not, replanting should be able to curb the issue.
Common garden pests like aphids, mealybugs and spider mites may also become an issue if left unmonitored. Treat with a natural, insecticidal soap or vinegar solution.
Why Are My Elephant's Ear Plant Leaves Drooping?
Drooping is usually a signifier for an underlying issue. If the leaves are enormous and drooping due to size, consider staking the leaves to give them some support.
If these leaves are small and still drooping, you may need to adjust the amount or frequency of watering. Drooping can also occur when there is a drop in temperature.
In these instances, move your Elephant's ear somewhere slightly warmer.
Why Are My Elephant's Ears Yellowing?
Leaf discolouration is usually due to a change in moisture or level of sunlight. First, check your soil. If the soil is waterlogged, replant. If the soil is draining well, consider giving your Elephant's ear a bit more morning sunshine.
Is Elephant's Ear Poisonous?
Yes, if ingested in large quantities, Elephant's ear can be toxic to humans and pets. The leaves and stem of the Elephant's ear plant contain oxalic acid, which is a large enough amount, and can be poisonous.
However, cooking the plant renders the toxins useless. Still, ingestion isn't recommended.
