Those pre-formed coco fiber pot/basket liners, can they be used instead of mulch around the base of a baby tree?

I've been trying to find mulch for moisture, bug and weed control around the base of a tree sapling. Mulch and straw bags are only available round here in >40L bags, but I have very little storage space (zero) and only one plant that needs mulch, so buying such a lot is a waste. I know you can also use coco coir as mulch, so could I buy a coco fiber pre-shaped pot liner, cut it to lay it flat, and use that as a mulch mat?
