A full permaculture guild consists of 7 layers (from Permaculture Guilds: A Primer)

  • canopy layer (only for larger gardens, not on roofs, balconies, etc.)
  • low tree layer
  • shrub layer
  • herbaceous layer
  • rhizosphere
  • soil surface (ground cover)
  • vertical layer (climbers and vines)

Each guild needs 5 things

  • nitrogen
  • nutrients/ dynamic accumulators (non mineral, mineral, soil)
  • mulch
  • pollination
  • protection from external threats
