In this unique reference, horticulturist Thomas Ogren reveals the role that urban landscaping plays in a time of increasing allergies and asthma rates. Whether you are a gardener, an allergy sufferer, or both, Allergy-Free Gardening will help you make informed decisions about landscaping choices and breathe easier!As his exhaustive research shows, our contact with allergens has skyrocketed due to short-sighted landscaping choices- specifically, the disproportionate cultivation of all-male “litter-free” plants, which bear no fruit but produce overwhelming amounts of pollen. Based on this ground-breaking research, Allergy-Free Gardening proposes a more health-conscious approach to public and home gardening, providing revolutionary strategies for creating allergy-free environments. Including over 3,000 detailed entries, this comprehensive guide rates the allergen-producing potential of common trees, shrubs, flowers, and other landscaping plants. Ogren’s rating system is so innovative that the USDA Urban Forestry Effects Model has adopted it as a way of ranking the allergy potential of entire cities. A 58 page, full-color photograph section featuring The Allergy Index Scale is included in Allergy-Free Gardening. Thomas Ogren started researching allergy-free gardening because his wife, his mother, and his sisters suffered from hay fever and asthma. He is a former landscape gardening instructor, nursery owner, and gardening radio show host, and an author with an M. S. is agricultural science. He lives with his family in San Louis Obispo, California. 267 pages
