2. Make weeding easy.

Can duct tape really be the secret to a weed-free garden? You bet! Because if you're comfortable doing something, then you'll do it well. Once you put on your work pants, fasten an old rectangular sponge to each knee with duct tape. Just go easy on the tape so you'll be able to remove it--and the padding--before you wash your trousers. Trust me. Weeding will be a breeze and your knees (and garden) will thank you!
