A regionally known gardening expert, radio and television host, author, columnist, and former horticulture specialist for Colorado State University Extension, John Cretti has more than 32 years of horticulture experience. John hosted the Gardening with an Altitude radio program for thirty years and has been an expert on Rocky Mountain Gardening for area TV and HGTV.
His down-to-earth approach broadens the horizons of gardeners dealing with the unique and challenging climates of the region, where temperature fluctuations, wind, hail, unpredictable storms, difficult soils, and cunning critters are the norm.
John has spent his life growing all kinds of plants, beginning as a child under the tutelage of his Italian grandmother, aunts, and uncle. This inspired his interest and passion for gardening while growing up in western Colorado.
John is the author of several books for Cool Springs Press, including Rocky Mountain Gardener’s Guide and Month-by-Month Gardening in the Rocky Mountains. Learn more about him at his website: www.gardeningwithanaltitude.com.
