Does it get a lot of sun where it's planted?

Yes it does!

overwatering could be a reason it's not getting larger, or not enough sun, or maybe both.

Think I'll pay more attention to these two factors.

Do you have a picture?

This is what it looks like compared to what I found on the net👇

Mine has been like that for close to a year now without the Leaves or whatever it's called getting bigger than you see there plus the image is even making it look as if it's big in reality they're all short with small leaves.
