Here are the answers:
Save on grocery money by planting a garden. Last year we planted cucumber seeds ($1 a packet) and had cukes all summer long (at the grocery store they cost $0.50 to $1 each). I bet we harvested close to 100 cucumbers--that's a ROI of about 5000%!
Start small if you've never gardened before. It's not hard, but if you do too much to start with, it can be overwhelming (I know from experience). Guess who planted the cucumbers? My 6-year-old, by himself.
