It's the first day of summer, the 21st of June. The sun is shining and flowers are in bloom. Today, you'll learn about one more thing that's colorful and free -- beautiful nature, in the form of birds and butterflies taking wing. Here's how to make your garden a hangout for these colorful creatures: To start a Disney-quality gathering of birds, create a shallow bird bath, with a drip tube attached to a hose that will keep it fresh and continually replenished. Add a nearby mix of seeds like millet and sunflower and bright, colorful blooms, like zinnias. Then, watch birds of a feather flock together. Want hummingbirds? Red or orange says ?nectar here.? To attract butterflies, leave out a slice of melon, especially near a clay pot saucer with moist stones. For more tips, visit our Web site at onthehouse.com. And that's the On The House tip for today.
