How To Propagate Alocasia

This guide will take you on a step-by-step journey through the propagation of alocasia plants by division, offsets, and corms.

Alocasia, also known as Elephant Ear, has species such as Alocasia Polly, Alocasia Zebrina, and Alocasia Amazonica. Another alocasia species is the Alocasia macrorrhiza, which has large leaves in the shape of a stingray. These plants are popular houseplants and are prized for their ornamental foliage, which features large, tropical leaves with distinctive veining.

Propagating Alocasia houseplants can be done through root cuttings, stem cuttings, leaf cuttings, and corms. Root cuttings are taken from the parent plant’s roots and planted in potting soil, while stem cuttings are taken from the stem. Leaf cuttings involve taking sections of a healthy leaf and planting them. Corms are underground bulbs that can be harvested to produce new plants.

Propagation Through Division Of Rhizomes

The first common propagation method is division, which involves carefully splitting the rhizomes of a mature plant into two or more parts, each with a root system. The parts can then be replanted in separate pots.

Plant rhizomes in a small pot and wait for new growth to appear.

Propagation Through Offsets

The second method of propagating Alocasia plants is from offsets, small plants that sprout from the base of the mother plant. Offsets can be easily removed from the mother plant and planted in a pot filled with a potting mix designed for tropical plants. You can also place the offset into water if it doesn’t have strong roots yet.

Once the offsets have been planted, water the soil until it is moist but not wet. Place the pot in a spot with indirect light, and you should start to see new growth within a few weeks. As the plant grows, you may need to repot it into a larger pot.

These propagation methods will also work with rhizomes, underground stems that store food for the plant and can be used to propagate new plants.

Alocasia plants can also be propagated from tubers, small, round bulbs that store food for the plant. To propagate Alocasia plants from tubers, you first soak the tuber in a bowl of lukewarm tap water for about 24 hours. You can then transfer them to the potting mix.

Offsets are baby plants, ready for their new home!

Propagation Through Corms

Alocasia propagation can be done through corms, underground storage structures similar to bulbs. Follow these steps:

  1. Carefully dig up the parent plant in the spring or fall and separate the corms from the root system or root ball.

  2. Clean the corms and allow them to dry for a few days.

  3. Plant the corms in well-draining soil, about 2 inches deep and 6 inches apart.

  4. Keep the soil moist but not waterlogged.

  5. Wait for new growth: Fresh shoots will emerge from the corms in 4 to 6 weeks, and new leaves will develop in 4 to 8 months.

You can also propagate Alocasia corms by placing the corms in a container with water at the bottom. Submerge the bottom of the corms in water. Cover the container with a dome to create a humid environment.

You should change the water every two to three days to prevent the corms from rotting. When the roots appear from the bottom of the corms, remove the corms and place them in the soil to get your baby plants.

Frequently Asked Questions

Can You Propagate Alocasia From Cuttings?

Alocasia can be propagated from root, stem, and leaf cuttings. Air layering is another tried and trusted method.

Propagation from root cuttings:

  • Take root cuttings in the spring or fall.

  • Plant the root cuttings in well-draining soil, about 2 inches deep and 6 inches apart.

  • Keep the soil moist but not waterlogged.

  • New shoots will emerge from the roots in 4-6 weeks, and new leaves will develop in 4-8 months.

Propagation from stem cuttings:

  • Use a pair of clean, sharp scissors, shears, or secateurs and cut a stem about 4 to 6 inches long, making sure to include at least two nodes (the places where leaves emerge from the stem).

  • Remove the bottom leaves, leaving two to three at the top.

  • Place the stem cutting in water or a well-draining soil mix.

  • Keep the soil moist and provide bright, indirect light.

  • Roots should form in 2-3 weeks, and new growth will emerge in 4 to 8 weeks.

Propagation from leaf cuttings:

  • Remove a healthy leaf from the parent plant.

  • Cut the leaf into 4 to 6-inch pieces, including a portion of the stem.

  • Plant the leaf cuttings in a well-draining soil mix.

  • Keep the soil damp and provide a bright, indirect light.

  • New growth will emerge from the stem nodes in 4 to 8 weeks.

It’s important to note that the success rate of propagation from root and stem cuttings is usually higher compared to leaf cuttings. Additionally, it may take several months for new growth to emerge, so patience is key.

Air layering is another common method of propagation, and it involves cutting a small part of the stem and rooting it in water or soil while still attached to the mother plant. Once the roots have sprouted from the stem, they can be cut off and replanted.

How Long Does It Take To Propagate Alocasia?

The time it takes depends on the method used. Propagation through root and stem cuttings usually takes 4 to 8 months, while propagation through leaf cuttings may take longer. Propagation through corms may also take 4 to 8 months, although new shoots will emerge from the corms in 4 to 6 weeks. Propagation through water and a dome may be quicker, with roots forming in 2 to 3 weeks and new growth emerging in 4 to 8 weeks.

The success rate of propagation and the time it takes to see new growth can vary based on factors such as temperature, humidity, light, and soil moisture, so it’s important to provide the best possible growing conditions for the Alocasia cuttings or corms.

What’s The Best Time Of Year To Propagate Alocasia?

The best time of year to propagate Alocasia depends on the method used. The best time to take cuttings for root and stem cuttings is in the spring or fall when the plant is actively growing. The best time to harvest and plant corms is in the spring or fall. You can take leaf cuttings at any time as long as they are healthy and free of damage.

Taking cuttings or harvesting corms during the growing season ensures that the parent plant has enough energy to regrow from the cuttings or corms. If cuttings or corms are taken during a period of dormancy, it may take longer for new growth to emerge.

What Size Pot Should Alocasia Offsets Be Planted In?

When planting Alocasia offsets, it’s important to use a large enough pot to accommodate the growing roots and leaves but not so big that the soil stays too moist for too long. A 6 to 8-inch diameter pot is a good size for most Alocasia offsets.

Using a well-draining soil mix appropriate for tropical plants is also important. Adding perlite, coco coir, or coarse sand to the soil mix can improve drainage, which is crucial for preventing root rot.

What Growing Conditions Do Propagated Alocasia Plants Need?

Propagated Alocasia plants need the following growing conditions:

  • They thrive in bright, indirect light but can tolerate some direct sunlight as long as it’s not too intense. If the leaves begin to yellow or fade, it’s a sign that the plant is receiving too much direct light and needs to be moved to a location with more shade.

  • Warm, consistent temperatures between 65 and 85°F are ideal for Alocasias. They can tolerate some fluctuations, but sudden temperature changes can be stressful for the plant.

  • They prefer a humid environment, so it’s important to maintain a consistent level of humidity in the air around the plant. Placing a tray of water near the plant, misting the leaves regularly, or using a humidifier can help maintain proper humidity levels.

  • Provide them with a well-draining soil mix that’s rich in organic matter. Adding perlite or coarse sand to the soil mix can improve drainage, which is crucial for preventing root rot.

  • The Alocasia is not a succulent, so regular watering is necessary, but do not allow the soil to stay consistently wet. Over-watering can kill Alocasia plants.
