I was curious if a banana would grow in 100 % Puerto Rican Coffee Grounds.
I planted one piece of corm in coffee and another in soil.
A banana will grow in CG but not very well, it seems the banana grows faster than the time it takes for the CG to break down.
Grass on the other hand, breaks down quickly and is available before the banana plant needs to use it.
I posted the photo for anyone else that might have also been curious.
