Blacksmith's Hanging Baskets
Lovely simple hanging baskets for tumbling toms or some beautiful herbs.
If you have a slug problem, try hanging these a little lower than usual and plant your salads off the ground.
Tip: use fresh plants and soil/compost as the little blighters hide in the roots, and you may just transfer them.
