Corms

Could someone explain what alocasia corms are cause I keep seeing and reading about them but don’t know what they are. I’ve been thinking about getting one aswell so just want to be educated. #PlantsMakePeopleHappy #PlantsMakePeopleHappy #PlantAddict #Alocasia #corms
Brendan, corms are produced by an alocasia mother plant (at least mine were) in the soil surrounding the main root ball. They look like cute little round nubbins. There are several ways you can start a corm. I used water and leca and I am very pleased with the result.
You can also buy corms online or a local nursery may have some. Here is a helpful article in relation to alocasia corms : https://sacredelements.world/blogs/houseplant-care/alocasia-care-and-growing-from-corms#:~:text=Peel%20away%20the%20outer%20shell,roots%20will%20begin%20to%20grow.
Hi Brendan 👋 basically a corm is a bulb! Not so Alocasia produce them, but many do.

I would be wary about buying them online though, I've heard about lemme being scammed, and you won't know if you actually got what you paid for until they've germinated! So make sure you get them from a reputable source!

Basically to germinate, you want to ...

1. Prepare the corms - you can gently peel away the outer shell of the corm with a knife, similar to peeling an onion, to help it sprout faster. Just be VETYcareful not to damage it! Lol 🫣

2. Use a small container with a lid. You could use a shot glass, to-go cup, or yoghurt pot for example

3. Add a thin layer of pumice, perlite or damp moss (I prefer moss but it's personal choice!) to the bottom of the container.

4. Place the corms on top of the layer, standing upright so that only the bottom of the corm is in water you're about to add. You can position them along the outer edge of the container.

5. Add a small amount of water so that the bottom of the corms is resting in it. The water level should be checked regularly as it may evaporate quickly. You can also spray the corms with water if the container starts to dry out.

6. Provide warmth and humidity. Place the container in a warm, humid environment with bright, indirect light. You can cover the container with a plastic bag or lid to help retain humidity.

7. Be patient! Depending on the type of Alocasia, it can take one to two months for the corms to produce leaves and roots. You can open the container every few days to check for rotting and remove any debris. Once the corms have grown two leaves, you can transplant them into a nursery pot to grow big and beautiful 🥰

Hope that helps! X
It all depends on what plant you want to grow with the corms. Examples of corm plants include: alocasia, elephant ear, colocasia (taro)…but I think the most popular is alocasia. I had an alocasia plant that wasn’t doing so well. I heard that there were these little corms that would be in the dirt, produced from the momma plant. Sure enough, there they were when I went searching. I tried several different ways to get the corm to root. What worked for me was water and leca. I have heard others use moss, perlite, a shallow dish of water, or even a thin layer of dirt for them to “start” in. Not all of them took (rooted) but majority of them did. You have to be very patient- but the wait is totally worth it!
@JenniB81 @theloveofplants Thank you both!
