I've seen old tires over fence posts and used as "no trespassing" signs, but this is another great use of an old tire. Put a drainage hole in the bottom, give it spritz of your favorite color and add flowers. I'd still hang it over a fence post though...it would look awesome along the road way, or the entrance of your home........D.
I never thought tires in a garden were attractive however this is pretty! I could imagine this attached to a shed a side fence vertical garden. Love the 'pop' of colour too. DIY Show Off
