Forest Garden Greenhouse

A forager and permaculturist with roots in rural Nebraska, Jerome Osentowski lives in a passive solar home he built at 7200 feet above Colorado’s Roaring Fork Valley. Director and founder of Central Rocky Mountain Permaculture Institute and a permaculture designer for thirty years, he has built five greenhouses for himself and scores of others for private clients and public schools in the Rockies and beyond. He makes his living from an intensively cultivated one acre of indoor and outdoor forest garden and plant nursery, which he uses as a backdrop for intensive permaculture and greenhouse design courses. Among his accomplishments is hosting the longest-running Permaculture Design Course in the world, now at twenty-nine years running. Jerome and Michael have also been instrumental in identifying, conserving, and propagating heritage fruit trees that have survived and borne crops for over a century in the harsh environment of the Roaring Fork Valley. Jerome’s explorations of sustainable systems and his travels for development projects have taken him to Baja, Nicaragua, Patagonia, Finland, Australia, and the Caribbean.

Publishers Weekly-"Osentowski shows how building and maintaining a Mediterranean or tropical greenhouse full of figs, lemons, papayas, and bananas can be both affordable and practical. Drawing on his 30 years of experimentation and teaching in the harsh, dry mountain environment of his Central Rocky Mountain Permaculture Institute, he offers lush descriptions of his five greenhouses and in-depth, layered advice on designing and constructing a balmy winter retreat. His method uses a 'climate battery’ consisting of tubes buried underground to collect and hold warm air from the greenhouse, which then recirculate it when the temperature cools, backed up in the coldest days with a pellet or wood stove that can simultaneously heat an attached sauna. Osentowski admits that he prefers a hands-on method of teaching, and his written tours through greenhouses are sometimes hard to follow. Novices may be intimidated by the lack of step-by-step, formulaic instruction. But more experienced gardeners, builders, and tinkerers, and even intrepid beginners willing to carefully observe, compute, and ponder, will find this readable guide jam-packed with enough information and inspiration to help them attempt their own indoor paradises.”
