Gutter Gardens - Are They Safe?
Someone sent me a photo today of a couple of rain gutters that were attached to the side wall of a house and planted with lettuce / onions / radishes, etc.
Sounds like a brilliant idea to add extra growing space, but I'm concerned about possible issues from growing in a metal (aluminum) container.
Anyone here know if this is safe for growing food, or who I can contact to ask about safety issues? Perhaps I could line the gutters with plastic first (more $$$ though...)?
I suppose a gutter planter would easily work for flowers, but I could really use the extra space for salad greens and such.
