Zuzu, these are to be sunk in the ground so presumably then the holes in the sides would have to be big enough that the roots themselves don't block the drainage? I'm not sure the dimensions of a ten gallon trash tub, on Google they mostly seem to be tall and narrow in which case I'm not sure I'd want to be digging the 15 holes to sink them in
Or maybe Tisha means those tubs with the rope handles, which are somewhat wider.
