The Alocasia Plant Basics
Native to the rainforests of Southeast Asia, particularly in countries like Indonesia, Malaysia, and the Philippines, Alocasias thrive in warm, humid environments.
With over 70 species, they vary in size, shape, and color, with some featuring dramatic veining, metallic hues, or wavy edges.
These plants are often referred to as “Elephant Ear” plants due to their broad, sculptural foliage.
In their natural habitat, they grow beneath the jungle canopy, enjoying filtered light and moist, well-draining soil.
Alocasias make excellent houseplants due to their unique aesthetics, air-purifying qualities, and ability to adapt to indoor conditions.
Their striking foliage adds a tropical touch to any space, making them a favorite among plant enthusiasts.
While they require high humidity, warm temperatures, and careful watering, their rapid growth and bold appearance make the effort worthwhile.
Additionally, Alocasias can be grown in soil or water, offering flexibility in care.

The Key Difference In Care Needs Across Alocasia Varieties
While most Alocasia varieties have similar care requirements, there are some differences based on species, size, and leaf texture.
Here’s a general guide to Alocasia care and key differences among varieties:
General Alocasia Care
🌿 Light: Bright, indirect light; some tolerate medium light, but most thrive with more brightness.
💦 Watering: Keep soil evenly moist but not soggy; allow the top 1-2 inches to dry before watering again. Avoid overwatering to prevent root rot.
💨 Humidity: High humidity (60%+ is best); misting, pebble trays, or humidifiers help.
🌡 Temperature: Warm temperatures (65-85°F / 18-29°C); avoid cold drafts.
🌱 Soil: Well-draining, airy mix (peat, perlite, orchid bark, and coco coir).
🌿 Fertilizer: Feed with a balanced fertilizer during the growing season (spring/summer); reduce in fall/winter.
🌿 Dormancy: Some Alocasia go dormant in winter (especially in cooler climates) and may lose leaves—this is normal!
Key Differences Between Alocasia Varieties
Size Matters – Larger varieties like A. macrorrhizos and A. portei need bigger pots and more frequent watering.
Compact types like ‘Black Velvet’ or ‘Silver Dragon’ need smaller pots and are prone to overwatering.
Leaf Texture – Velvety types like ‘Frydek’ and ‘Black Velvet’ are more sensitive to low humidity and prone to fungal issues if overwatered.
Tough-leafed species like A. macrorrhizos or A. odora are more forgiving.
Dormancy Sensitivity – Some, like A. odora and A. macrorrhizos, stay semi-active year-round, while others (e.g., ‘Silver Dragon’ and ‘Maharani’) are more prone to winter dormancy.
Humidity Tolerance – Some hybrids, such as A. zebrina, tolerate lower humidity better than A. baginda ‘Dragon Scale’, which thrives in 80%+ humidity.
Pest Resistance – Thin-leaved Alocasias like A. zebrina and A. amazonica are more prone to spider mites, while thicker-leaved varieties like ‘Melo’ resist pests better.
Special Care Tips by Variety
🖤 ‘Black Velvet’ / ‘Silver Dragon’ / ‘Maharani’ – Avoid overwatering; prefers more humidity but less frequent watering.
🐍 A. Zebrina – Can tolerate lower humidity but needs good airflow to prevent spider mites.
🐉 ‘Dragon Scale’ / ‘Red Secret’ / ‘Melo’ – Loves very high humidity and well-draining soil.
🌳 A. Macrorrhizos / A. Odora – More adaptable, less fussy about humidity, but needs more space.
🍃 A. Amazonica ‘Polly’ / ‘Bambino’ – Prone to drying out, needs consistent moisture but well-draining soil.
Now that you understand the key difference between the different Alocasia varieties I will now cover the basic care needs of this evergreen plant in more detail.
Indoor Alocasia Care Needs: A Step By Step Guide
Below are the basic care requirements for indoor Alocasia plants.
1. Light
Prefers bright, indirect light; avoid direct sunlight as it can scorch the leaves.
Some varieties can tolerate lower light, but growth may slow down.
2. Watering
Keep soil lightly moist but not soggy. Let the top 2-3 inches dry out before watering again.
Use room temperature, filtered, or dechlorinated water to prevent mineral buildup.
Reduce watering in winter when the plant enters dormancy.
You cab get a more in-depth guide about hydrating your plant by reading our Alocasia watering guide.
3. Humidity
Thrives in high humidity levels (50-60%).
If the air is dry, use a humidifier, pebble tray, or mist occasionally.
4. Temperature
Prefers warm temperatures between 65-85°F (18-29°C).
Keep away from cold drafts, AC vents, and sudden temperature drops.
5. Soil
Needs well-draining, aerated soil that retains some moisture but doesn’t stay soggy.
Ideal mix: 50% aerating materials (perlite, coco coir, bark) + 50% organic matter (peat, compost, or potting soil).
Prefers slightly acidic soil (pH 5.5-6.5).
Read our guide to planting elephant ear bulbs for a more detailed guide.
6. Fertilizing
Feed with a balanced liquid fertilizer (20-20-20) every 3-4 weeks during the growing season.
Avoid fertilizing in winter when the plant is dormant.
Although you may come across other sites with contrary information you should never use coffee grounds on elephant ears.
7. Pot & Drainage
Use a pot with drainage holes to prevent root rot.
If using a decorative pot without drainage, place the plant in a grow pot inside and remove excess water after watering.
8. Pruning & Maintenance
Remove yellow or dead leaves regularly to encourage new growth.
Wipe leaves with a damp cloth to remove dust and improve photosynthesis.
Aerate the soil occasionally to improve oxygen flow to the roots.
9. Propagation
Alocasias grow from rhizomes, so they can’t be propagated from cuttings.
To propagate, divide the rhizomes or separate baby plants (offsets) when repotting.
10. Pests & Diseases
Common pests: Spider mites, aphids, mealybugs, and scale—treat with insecticidal soap or neem oil.
Watch for root rot, which occurs due to overwatering and poor drainage.
How To Care For Alocasia Plants Outdoors
Growing Alocasia outdoors can be rewarding, as these tropical plants thrive in warm, humid environments.
Whether used as a garden centerpiece or in pots on a patio, Alocasias bring a dramatic, lush feel to outdoor spaces.
Here’s how to care for them properly:
1. Outdoor Light Requirements
Alocasias prefer bright, indirect sunlight or partial shade when grown outdoors.
Direct sunlight for extended periods can scorch their leaves, so filtered light under trees or a shade cloth is ideal.
Some larger varieties, like Alocasia macrorrhiza, can tolerate more sun if acclimated gradually.
2. Temperature and Humidity
These tropical plants thrive in warm temperatures between 65–85°F (18–29°C).
They do not tolerate frost, so if you live in a colder climate, grow them in pots and bring them indoors before temperatures drop below 50°F (10°C).
High humidity (above 50%) is ideal. If you live in a dry climate, mist the leaves occasionally or place them near a water feature to increase humidity.
3. Watering Your Outdoor Alocasia
Keep the soil moist but not soggy. Water when the top 2–3 inches of soil feel dry.
Avoid overwatering, as Alocasias are prone to root rot. Ensure good drainage in both in-ground and potted plants.
Reduce watering in cooler months when growth slows.
4. Outdoor Soil Requirements
Use well-draining, rich soil that retains some moisture without becoming waterlogged.
A mix of peat, perlite, and compost works well. If growing in the ground, amend the soil with organic matter for better aeration and drainage.
5. Fertilizing
Feed every 2–4 weeks during the growing season (spring and summer) with a balanced liquid fertilizer (20-20-20).
Reduce fertilization in fall and winter when growth slows.
6. Protection from Pests and Diseases
Keep an eye out for spider mites, aphids, and mealybugs. Treat infestations with insecticidal soap or neem oil.
Avoid waterlogging, which can lead to fungal infections and root rot.
7. Overwintering
In colder climates, move potted Alocasias indoors before frost.
If planted in the ground, dig up the rhizomes, dry them, and store them in a cool, dry place for replanting in spring.
By providing the right balance of warmth, humidity, and moisture, Alocasias can thrive outdoors, adding a tropical, exotic touch to your garden or patio.
