Care For Elephant Ear Plants
When it comes to planting and growing elephant ear plants, there are a few key factors to keep in mind. First and foremost, choose a location that provides medium to wet soil and partial shade or filtered sun. These plants thrive in moist conditions, so it’s important to ensure that the soil doesn’t dry out completely.
To plant the tubers, dig a hole that is 1-2 inches deep and place the tuber in it, with the pointed end facing upward. Cover the tuber with soil, making sure it is well-packed. Regular watering is crucial for the growth of elephant ear plants, especially during the active growing season. Aim to water them consistently, keeping the soil moist but not waterlogged. Fertilizing the plants once a month with a nitrogen-rich fertilizer can also help promote healthy growth.
In colder regions, it’s important to overwinter the tubers indoors or store them in a cool, dark place to protect them from frost. When the growing season is over, carefully dig up the tubers and remove any excess soil. Store them in a dry and cool location until the next growing season. It’s worth noting that elephant ear plants can also be propagated by dividing the tubers or planting seeds, although seed propagation can be more challenging.

Care Tips for Elephant Ear Plants
To ensure the health and vitality of your elephant ear plants, proper care is essential. Here are some valuable tips to help you maintain these stunning tropical perennials:
- Provide Adequate Moisture: Elephant ear plants thrive in moist soil, so it’s crucial to keep the soil consistently damp. Regular watering is necessary, especially during the active growing season. However, be mindful not to overwater, as this can lead to root rot.
- Maintain High Humidity: These plants love humidity, so consider misting their leaves regularly or placing a humidifier nearby. This will help replicate their natural tropical habitat and promote healthy growth.
- Trim Faded Leaves: Removing any old or yellowing leaves is an important part of caring for elephant ear plants. Not only does this improve the overall appearance, but it also encourages new growth to emerge.
- Overwintering Indoors: In colder regions, overwintering elephant ear plants indoors is crucial for their survival. Bring them inside before the first frost and place them in a bright location with temperatures between 60-70°F (15-21°C). Reduce watering and allow the soil to dry slightly between waterings.
By following these care tips, you can enjoy the beauty of elephant ear plants year-round and ensure their longevity.
Common Issues and How to Address Them:
| Issue | Symptoms | Solution |
|---|---|---|
| Spider Mites | Webbing on leaves, discolored and distorted foliage | Boost humidity, spray leaves with water, or use insecticidal soap |
| Yellowing and Drooping Leaves | Signs of underwatering or low humidity | Ensure sufficient watering and increase humidity levels |
| Leaf Scorch | Brown, scorched patches on leaves | Gradually acclimate plants to indirect light and provide some shade during the hottest part of the day |
Remember, elephant ear plants are toxic if ingested, so exercise caution when selecting their planting location, especially if you have children or pets. With proper care, these magnificent plants will thrive and add a touch of tropical beauty to your indoor or outdoor space.

Troubleshooting Common Problems with Elephant Ear Plants
As beautiful and resilient as elephant ear plants can be, they are not immune to certain problems. Here are some common issues you may encounter and how to address them:
1. Spider Mite Infestation:
Spider mites can be a nuisance, causing yellow spots and webbing on the leaves. To control these pests, regularly mist the plant to increase humidity. You can also wipe the leaves with a damp cloth or use an insecticidal soap solution.
2. Yellowing and Drooping Leaves:
If your elephant ear plant’s leaves are turning yellow and drooping, it may be a sign of underwatering or low humidity. Ensure the soil is consistently moist, but not waterlogged, and consider placing the plant near a humidifier or on a pebble tray filled with water to boost humidity levels.
3. Leaf Scorch:
Leaf scorch, characterized by brown or dried-out leaf edges, can occur if the plant is exposed to intense sunlight too suddenly. Gradually acclimate your elephant ear plant to direct sunlight by placing it in a partially shaded area and gradually increasing sun exposure over a few weeks.
Remember, it’s important to handle elephant ear plants with care as they are toxic to humans and pets. If you have young children or animals, consider placing the plants in areas where they cannot be easily accessed. By troubleshooting these common issues, you can ensure your elephant ear plants thrive and continue to add a touch of tropical beauty to your surroundings.
4. Leaves yellowing or browning:
This can be caused by too much sun, underwatering, or low humidity. Move to partial shade, improve watering consistency, and increase humidity.
5. Wilting or drooping leaves:
Elephant ears wilt easily if allowed to dry out. Check soil moisture and water thoroughly. Can also be a sign of root rot from overwatering.
6. Holes in leaves:
Indicates insect pests like aphids. Treat with horticultural oil or insecticidal soap sprays. Ensure good airflow.
7. Spots on leaves:
Fungal leaf spot diseases are common. Improve air circulation and use copper fungicide sprays. Remove severely damaged leaves.
8. Leggy growth:
Insufficient sunlight causes leggy growth. Move to a brighter location and prune leggy stems back.
9. Failure to bloom:
Lack of sun and too much nitrogen fertilizer inhibits blooming. Provide more direct sun and use a low nitrogen fertilizer.
10. Root Rot(Tubers rotting):
Overwatering causes tubers to rot, especially in cold climates. Plant in well-draining soil and avoid excessive moisture.
11. Petioles detach:
Generally caused by physical damage from wind or handling. Stake plants to protect from wind. Handle leaves and stems gently.
Always diagnose the specific cause and take appropriate corrective action to restore elephant ears to health. Prevent issues by providing optimal care.
Propagating Elephant Ear Plants
Elephant ear plants can be propagated by several methods to produce new plants. This allows you to multiply your collection at no cost. The main propagation methods include:
Propagation Methods:
- Division – Separating offsets called pups or suckers from the mother plant
- Seed – Starting new plants from seed pods produced on flowers
- Corms – Dividing underground corms when the plant is dormant
- Cuttings – Taking cuttings of stems with nodes/leaves
Division
Division involves carefully separating small new plants or shoots growing around the base of the mother plant.
When to Divide:
- Spring after new growth emerges
- OR fall when plant enters dormancy
How to Divide:
- Water plant well a few days before
- Gently separate shoots from the mother plant
- Ensure each division has roots and stems attached
- Plant divisions in pots with well-draining soil
- Water and provide high humidity initially
Seed
If the plant produces flowers and seed pods, seeds can be collected.
How to Grow from Seed:
- Collect seeds when pods turn brown and split
- Sow seeds 1⁄4 inch deep in seed starting mix
- Keep mix moist but not saturated
- Germination takes 1-8 weeks at 70-80°F
- Transplant seedlings after 2nd set of leaves grow
Corms
The underground corms can be divided when elephant ears go dormant in fall or winter.
Corm Division:
- Carefully dig up dormant corms
- Gently separate smaller corms with a sterile knife
- Ensure each corm division has visible growth buds
- Replant divisions 3-4 inches deep in rich soil
- Water sparingly until spring growth emerges
Stem Cuttings
Tip cuttings from stems will root but can be slower and less reliable.
Taking Cuttings:
- Use a sharp, sterilized knife or shears
- Cut a 4-6 inch portion of stem right below a leaf node
- Remove lower leaves except top few pairs
- Dip cut end in rooting hormone (optional)
- Plant in soil or water and provide high humidity
- Should root in 4-8 weeks
Proper methods will produce new vigorous elephant ear plants in a single season for expanding your collection.
