If rainwater cascading down your roof valley causes a waterfall that washes out the petunias every time it storms, do this simple fix. It costs only a few dollars and takes about 20 minutes to complete. You can find these precut gutter splash guards (about $3) in both brown and white aluminum at a home center, but you could easily make your own out of aluminum or sheet metal and spray paint them to match your gutters. If you don’t own a Pop riveter, attach the guards with 1/2-in. sheet metal screws instead.
