Now that it's spring, it's time to start planting your backyard gardens. One way to make sure your summer harvest is plentiful is to look at your Christmas ornament stash. Find plastic or unbreakable red ball ornaments and bring them outside. When your young plants are growing, the red ornaments will appear to be real food for birds. When they peck away and realize it's a hard, inedible object, they'll learn to leave the plants alone. So come harvest time for juicy tomatoes and other garden treats, you'll have more for you and less lost to wildlife.
