Why is my Alocasia so small?
This plant can be a bit sensitive, so ensuring it gets enough light, not too much sun and just the right amount of humidity is essential. It also likes to rest sometimes, so give it space.
It could be that your plant just needs a little more nutrition, or maybe your pot is too small. I'd recommend trying a plant food that dissolves in water, like a 20-20-20 fertilizer mix, and giving the plant a slightly larger pot, around 2 inches.
