A juicy, sweet slice of watermelon is a taste of summer. It’s fun to eat and is good for you. Choose from dozens of varieties for your garden this year. Some are small and round; others are large and oblong. The rind can be solid, striped, or marbled and range from light green to nearly black. The flesh is usually red, but can be pink, orange or yellow. Watermelons require some space, but are easy to grow in the backyard.
