Understanding Roots

By Robert Kourik, 225 pages

Understanding Roots uncovers one of the greatest mysteries underground: the secret lives of the roots of plants that move and grow invisibly beneath our feet. Roots do more than just keep a plant from falling over; they gather water and nutrients, exude wondrous elixirs to create good soil, make friends with microbes and fungi, communicate with other roots, and adapt themselves to all manner of soils, winds, and climates - nourishing and sustaining our gardens, lawns, and woodlands.


  • Describes how roots work their magic to improve soil nutrients
  • Investigates the hidden life of soil microbes and their mysterious relationship to roots
  • Contains over 115 enchanting and revealing - yet realistic - drawings
  • Explores the question of whether deep roots really gather more unique nutrients than shallow roots
  • Provides a detailed review of all aspects of transplanting
  • Shares the latest research about the mysteries of mycorrhizal (good fungal) association
  • Shows you exactly where to put your fertilizer, compost, water, and mulch to help plants flourish
  • Explains why gray water increases crop yields more than fresh water
  • Reveals the science behind it all (with citations for each scientific paper)
