ALERT this is a green on green project! Recycle, upcycle, reuse, repurpose however you call it.... simple, easy, great for kids and scouts.... and adults... FREE project.. I am thinking using plumbing clamps would add some flair! Use hemp cord or twine to hang... a great idea spark! Too bad for plants that I ALWAYS WITHOUT FAIL KILL THEM.
Plants have best friends just like people do. Marigolds help tomatoes and roses grow better. Nasturtiums keep bugs away from squash and broccoli. Petunias protect beans from beetles and oregano chases them away from cucumbers. Geraniums keep Japanese beetles away from roses and corn. Chives make carrots sweeter, and basil makes tomatoes even tastier.
