You have moved to a beautiful and unique place. Colorado's low humidity makes cold days seem less cold and hot days less hot. It also discourages many landscape plant diseases. In spite of some unique gardening challenges, you can grow a beautiful healthy lawn, abundant veggies, eye-catching flowers and trees to shade you from summer's heat. Dig in, adapt to a new gardening environment and be flexible.
