Mitzi I can answer this bescaue my family lives down there! You are outside of my color planting schedule by about a month. The trick is, Las Vegas gets so hot in the summer, but you can grow almost all winter long. My book is really for a spring-summer-fall planting schedule. The dates I offer might work for you and others who live in warmer climates, but really have a spring-summer and a fall-winter season. I am very aware of your needs, and it’s on my list of things to research and write about. But honestly, I can’t speak from experience, only from my research. I encourage you to contact your local extension service (www.extension.org) for a recommended planting schedule.
