Is it a fantasy of yours to live in a tropical paradise? When you look out the window do you crave palm trees and beaches, but instead see a backyard that is uninviting and dreary. Here's how to create a little fantasy-island adventure in your own backyard. Start with a simple water-garden pond with a shallow depth of 2 feet or less. It can range from a few feet square to swimming-pool size. Once excavated, line it with heavy vinyl sheeting or use a pre-fab plastic pool. Then go native with rocks, trees and foliage, creating your own tropical-island look. Add a waterfall or underwater lights and color lights to accent landscaping. A circulating pump and filtration system will keep water clean and mosquito-free. Adding a few fish will also help. Finally, add some good water plants for character. It'll help keep pond water fresh and clear, too. And that's the On The House tip for today.
