This book uncovers one of the greatest mysteries of the underground—the secret lives of roots. Illustrated with 140 enchanting and revealing root drawings by horticulturalists literally working in the trenches, it’s a superb guide to raising better trees and shrubs and growing abundant fruits, vegetables, and flowers. Among other science-based secrets, you’ll learn how to apply mulch, fertilizers, compost, and water for the most abundant growth. With eighty percent more new information than the best-selling Roots Demystified: Change Your Garden Habits to Help Roots Thrive, this is NOT a revised edition—it’s a whole new book.
"Robert Kourik has re-visted roots with his trademark humor, detail and curiosity. Delving into historical drawings, re-doing the chart on dynamic accumulators and pushing beyond the already extensive information contained within his previous Roots Demystified, Kourik has compiled a resource that will be definitive for many years to come. Unconfined, he roams through soil facts, planting techniques, scientific studies and folk wisdom to enlighten every gardener. Always ready to explore both sides of an argument, Kourik pulls our heads out of the clouds and reveals what is happening beneath our feet."
I have this book and it's pretty cool and contains some really interesting information. One thing I learned from this book is less than 5% of all trees have a taproot, and if that taproot is severed, like during transplanting for instance, it never grows back. Another interesting topic discussed in this publication is where in the soil horizons roots gather nutrients, and wether deep rooted plants may or may not actually bring nutrients up from way down deep. It contains tons of drawings, and is a quick and easy book to read, and I do recommend it.
