How to Grow Alocasia from a Bulb

Growing beautiful Alocasia plants from bulbs is a rewarding way to add these tropical-looking beauties to your home or garden. Alocasias, also known as elephant ears, boast large, heart-shaped leaves on long, upright stems. The lush foliage comes in varied colors like deep green, blue-green, silver, and purple.

While you can find Alocasia plants at nurseries, propagating them yourself from bulbs allows you to expand your collection inexpensively. With a little time and patience, the bulbs will sprout into gorgeous, full plants.

Follow this simple, step-by-step guide to successfully grow Alocasia from bulbs.

Elephant Ears Propagation in 3 Simple Ways: A Quick Guide

Gathering Materials

Before planting, you’ll need to gather a few materials:

• Alocasia bulbs – Look for plump, firm bulbs that are free from mold, mushiness, or rot. The attached roots are a good sign.
• Potting mix – Use a well-draining potting soil or a cactus/succulent mix.
• Small gravel or rocks – For extra drainage in the pot bottom.
• Plastic greenhouse dome or glass cloche – To maintain humidity around the bulbs.
• Spray bottle – For misting the bulbs.
• Bright, filtered light – Alocasia prefers indirect sunlight.
• Small pot with drainage holes – To plant each bulb separately.

Step 1: Prepare the Potting Mix

Start by filling your pot with the potting mix, leaving 2 inches from the rim. Mix in a handful of small rocks or gravel. This boosts drainage to prevent wet soil from causing bulb rot.

Press down lightly on the mix to make an even surface.

Step 2: Plant the Bulb

Place the Alocasia bulb in the pot, root-side down. Position upright, with the top 20-30% sticking out above the soil line.

The upper part of the bulb needs air exposure to grow. But the bottom needs soil contact for the roots to anchor and expand.

Step 3: Cover the Bulb

Water the potting mix well until it’s moist but not soaked.

Then place the plastic greenhouse dome or glass cloche over the pot. This creates humidity, which the bulb needs to sprout.

Step 4: Provide Gentle Light

Put the pot with the covered bulb in a warm spot with bright, filtered light.

An east or west-facing window is ideal. Avoid direct hot sunlight, which can damage the tender new growth.

Step 5: Maintain Moisture

Check the soil moisture every few days. Water cautiously when the top inch feels dry.

Use a spray bottle to mist the bulb and soil instead of pouring water over it. Too much moisture invites diseases.

Step 6: Watch for Growth

Be patient! It can take up to 3 months for the bulb to sprout.

First, you’ll see little white nubs emerging from the bulb. These grow into roots. Soon, leaves will unfurl.

Step 7: Acclimate the Seedling

Once the seedling is 3-4 inches tall, start exposing it to less humidity.

Remove the greenhouse cover for a few hours at a time over several weeks. This hardens off the plant.

Step 8: Transplant Mature Plants

When growth fills the pot, it’s time to transplant into a larger one.

Use fresh, well-draining potting mix. Established Alocasias also enjoy partial shade outdoors.

Troubleshooting Issues

Growing Alocasia from bulbs is mostly smooth sailing. But here are some potential issues and solutions:

Problem	Solution
Soft, moldy bulbs that rot quickly.	The bulbs may have been damaged or diseased. Start over with fresh, healthy bulbs.
Bulbs not sprouting for many months.	Ensure the bulbs get gentle warmth and high humidity. Discard bulbs that still don’t grow.
Tiny black spots on leaves.	This could be a fungus. Improve air circulation and cut back on moisture.
Curled, yellowing leaves.	Plants may be getting too much light. Move them to a shadier spot.

Caring for Mature Alocasia Plants

With the right care, your Alocasia grown from a bulb will mature into a stunning houseplant or garden focal point:

• Water thoroughly when the top several inches of soil become dry. Avoid getting water on the leaves.
• Mist leaves occasionally to boost humidity.
• Fertilize monthly in spring and summer with balanced, diluted liquid fertilizer.
• Repot when rootbound into bigger pots with drainage holes.
• Prune back any mushy, damaged, or dead leaves and stems.
• Keep leaves dust-free by wiping gently with a damp cloth.
• Rotate the plant periodically so all sides get light exposure.
• Protect from frost and temperatures below 50°F.
