How to care for Elephant ear plants?
Light
Elephant ears flourish best when placed in the brightest light possible or part shade area, away from direct sunlight.
Elephant ears subjected to a long period of direct sunlight may result in leaf burn because the plant is not accustomed to such light intensity.
As a result, the leaves will generally appear bleached, losing their decorative foliage effects and colouration from your landscape.
However, Caladium ‘Miss Muffet’, Caladim ‘red flash’ and, Xanthosoma Lindenii are few exceptions in that they can tolerate direct sunlight, and still retain their foliage effects.
Teperature
Ideally, Elephant ears should be exposed to a temperature range of 65°F to 75°F with a correspondingly high level of humidity, which is essential for pot plants in warmer rooms.
You can Increase humidity by standing pots on trays of moist pebbles or use a humidifier and mist-spray leaves daily.
Watering
Being a tropical plant, Elephant ears need moderate watering, just enough to keep the compost moist, especially during the active growth period.
Reduce the frequency of watering by watering sparingly during the rest period, say once a month. If you allow water to dry out from the compost in-between watering the plant may go dormant. In that case, you harvest the tuber and save until the temperature gets warmer.
Feeding
Elephant ears are heavy feeders. Apply standard liquid fertilizer at half strength twice a month during the active growth period (follow feeding instructions on how to apply).
Growing Elephant ear plant indoors
Successful growing of Elephant ears in pots and other indoor plants starts with proper shopping. You need to how to buy and what to check when buying your plants.
your plant will only be as good as the compost they grow in.
Nowadays, elephant ears are everywhere available for everyone especially to plant lovers, but choosing a healthy one that will flourish is not always a straightforward task.
Here’s what you need to know about navigating the whole experience.
How to propagate Elephant ear plants?
Elephant ears can easily be propagated by easy division in healthy plants with multiple tubers or corms.
Detach the small tubers from the mother plant with care, so as not to injure the mother. This is best done in spring.
Ensure the tubers are potted upwards into appropriately sized pots. For example, 3 inches pots are appropriate for small tubers, and 5 inches pots for larger tubers.
How to root elephant ears?
For dormant tubers, they should be buried facing upwards in the pot at about their own depth from the surface. For instance, plant a 2 inches tuber an inch below the surface.

How to overwinter Elephant ears?
It is usually not encouraged to force a tropical plant to grow actively during the winter rest period.
The amount of daylight is basically the limiting factor. For instance, Elephant ears have an annual period of dormancy during which leaves begin to dry out and die back even if other growth factors like warmth, feeding and watering are right.
So it is recommended to store-dry your elephant ears throughout the dormant period by doing the following:
- Cut back foliage
- Dig up the tubers or corms
- Remove dirt and allow to dry for a few days
- Store in a cool, dry, and dark environment
Pests and diseases of Elephant ears
Plant diseases are caused by pathogens, which can either be a virus, bacteria, or fungi.
Fungal attacks on plants often come from the soil and most times are difficult to treat.
Every plant is prone to pests and diseases. This is particularly so for Elephant ear bulbs if not well rooted and in the best planting medium. It is easier to completely eradicate plant diseases if detected early.
Let’s look at the major pest and disease problems associated with Elephant ear plants.
Spider mites
Spider mites are tiny sucking insects that feed on plant sap. They make silky webbing on the leaves, thereby leaving patches on the leaves.
The patches gradually turn pale yellow to black irregular spots. Their activities result in Elephant ear plant leaves turning yellowing and total leaf loss.
Control
Trim off affected leaves. Mix water, liquid dish soap, and Neem oil in a spray bottle. 5mls of Neem oil and 3 drops of dish soap.
Thrips
Thrips are small to tiny sucking insects that feed by piercing the leaf tissue and sucking out the cell content.
They are translucent white, yellowish, dark-brown, black or brightly coloured in some species.
Control
Trim affected areas. Spray mildly using pesticides or neem oil. Repeat the treatment every 2 weeks until the 3rd application.

Mealybugs
Mealybugs are sucking insects that feed on plant sap. Their activities result in Elephant ear plant leaves turning yellowing and total leaf loss.
Control
Trim off some foliage to loosen up. Dip a thin boarded brush in denatured alcohol and apply it directly to the insects.
For serious infestation use insecticidal soap -mix water, liquid dish soap, and neem oil in a spray bottle. 5mls of Neem oil and 3 drops of dish soap.
Snails and Slugs
Snails are chewing organisms that leave irregular holes in leaves and flowers. Their activities if not detected early will result in great damage.
Control
Pick off and destroy individual snails. Apply snail pellets to the base of the plant.

Caterpilars
Caterpillars chew leaves and stems, making holes or notched edges. Their activities result in great damage in case of severe infestation.
Control
Pick off and destroy individual caterpillars. Spray mildly using pesticides or neem oil.
Leaf spot
Infected leaves turn brown or black, sometimes with a yellow halo or lesions. The spots enlarge gradually and spread to the entire leaves.
Control
Trim affected areas to improve air circulation and sunlight. At the first sign of the disease apply neem oil, sulfur sprays or copper-based fungicides weekly to prevent its spread.
Note: These organic fungicides will not kill leaf spot but will prevent the spores from germinating.

Leaf blight
Late blight is caused by a fungus called Phytophthora infestans.
Late blight is a serious disease that can damage the entire plant if left unattended. The Phytophthora infestans form lesions on the leaves, which are light brown or tan in colour, irregular in shape, and can be found anywhere on the plant especially at the top part of young leaves.
The fungus spreads slowly to the entire plant. The leaves turn brown, shrivel, and die.
Control
Trim affected areas to improve air circulation and sunlight. Apply sulfur sprays or copper-based fungicides weekly at the first sign of disease to prevent its spread.
If you see no improvement after the treatments harvest the plant from the ground into an air-tight plastic bag and trash.
