Forest Gardens are orchards designed in such a way so the needs of the heavy bearing heavy feeding fruit trees are taken care of in the design.

We do this by:

  • Ensuring no more than 60% of the canopy space is taken up by heavy feeders. We prefer 40%.
  • For every square metre of heavy feeder canopy there is 0.8 of a square metre of nitrogen fixer.
  • For every square metre of heavy feeder there is 1 comfrey plant.
  • You have all seven (7) layers of the forest garden present.
  • You have as wide a range of mineral accumulators present.
