There are so many reasons to love Alocasia, from their unique leaf shape to their gorgeous vein patterns and their incredible variety of colors. In this blog, we do a deep dive into Alocasia care.
Best Soil for Alocasia
Alocasia Watering Requirements
Because Alocasia plants prefer well-draining soils, they do not like to sit in any standing water. It’s best not to let them dry out completely either. Let the top half of your soil dry out with the bottom half staying moist before you water again.
The Type of Light Alocasia Need
Most Alocasia plants need shade, but some large varieties like Alocasia macrorrhiza ‘Borneo Giant’ can tolerate full sun. Smaller varieties like Alocasia reginula ‘Black Velvet’ and Alocasia cuprea prefer darker environments. That being said, indoor lighting environments are considerable darker than their natural outdoor ones. Bright, indirect light like an Eastern-facing window is best for most Alocasia varieties in your home.
Alocasia Humidity Requirements
Alocasia plants are tropical, so they prefer moderate to high humidity indoors. Typical indoor conditions would work for Alocasia, potentially adding some humidity during dry Winter months. Aim for 60-80% humidity for happy plants.
Stick with fertilizing Alocasia during the growing season from Spring through Summer. Espoma’s Organic Indoor Houseplant Food is an all-purpose liquid fertilizer you can use every two to four weeks during the growing season for healthy, new growth.
Common Alocasia Problems
Alocasia plants can be prone to root rot, so it’s important not to over-water. To help prevent over watering, try keeping your Alocasia a bit more root bound. If your pot is too big, it’s much easier to give your plants too much water because it takes the soil longer to dry out.
Alocasia Dormancy Period
Most Alocasia varieties will go “half dormant” in the Winter, where they tend to look like they might be dying. You may even observe your Alocasia trying to flower, which really takes a lot of energy out of the plant.
But don’t worry! This is completely normal for Alocasia plants during the Winter months. Make sure to leave the yellowing leaves for the plant to absorb that energy back into itself, and your Alocasia should come back just fine in Spring. In the Spring, remove dead leaves and continue watering and giving it light and new growth should show up in no time.
