What is a “gutter garden”?
Husband took several pieces of guttering and brackets and hung the guttering on the side of the garage in three rows. He put a little dirt in it; but, so far, I don’t recommend it. Soil’s too shallow; it’s messy (dirt goes down the side of the garage when you water it). I’ve indulged him in this. Only one gutter row actually sprouted. I think it’s a mess and a waste; a lot of trouble to water, but I’m keeping an open mind
