3. Humidity and Temperature
This tropical plant loves warmth and humidity. Aim for temperatures above 60°F and humidity levels of 60-70%. Use a pebble tray or humidifier to maintain the right conditions.

Propagation and Repotting: Keep Your Alocasia Thriving

To propagate and repot an alocasia, you can divide the rhizomes or stolons, or plant corms. The key is to use a well-draining potting mix, keep the soil moist, and place the plant in bright, indirect light.
Propagation by division
- Remove the plant from its pot
- Check for root rot and remove any damaged sections
- Divide the rhizomes or stolons into pieces with at least one growth bud
- Plant the pieces in a new pot with fresh potting mix
- Place the pot in a warm location with bright, indirect light
- Keep the soil moist until new growth appears
Propagation by corms
- Harvest the corms from the plant when it needs to be repotted
- Place the corms in a terrarium or jar with high humidity
- Keep the soil moist and in a bright location
- Wait for new shoots to appear
Repotting:
To keep your Alocasia thriving, you can repot it when the roots are overcrowded or when it’s time for a soil refresh. The best time to repot is in the spring when the plant is actively growing again.
- Repot every 6–12 months for younger plants
- Repot every 2–3 years for mature plants
- Repot when the roots are overcrowded or start to poke out of the pot’s drainage holes
- Choose a pot that’s 1–2 inches wider than the current pot
- Fill the bottom third of the pot with well-draining potting soil
- Place the plant in the pot so that the roots go down the sides of the mound
- Cover the rest of the roots with soil until the container is full
- Press the soil down to eliminate air pockets
- Water the plant well until it seeps out of the bottom of the pot
