“Gardening for wildlife is a special interest of mine,” notes Paul. “Consider migratory birds flying over the desert today. Their ancestors stopped along the Agua Fria River, but with development and wetlands destruction, there is now limited water and habitat along these traditional routes.” Most people enjoy the cooling effect water brings to the landscape, he says. “Why not have an organic water garden that blends with our regional aesthetic and is beneficial to wildlife rather than lawns and swimming pools?” He also states that research has shown that a well-designed natural pond uses less water than a comparable area of turf.

The couple encourages people to work with Mother Nature. “If water turns green, avoid using chemicals to clear it. Green water is a balance problem,” Paul explains. “If your pond has a good filter and circulation system, plus an appropriate blend of rocks, plants and fish, the ecosystem will balance itself and clear the water. Just practice a little patience.”
