Bog Gardens

What is a bog garden?
  1. Types of bogs:

  2. A. Wild bogs:
    B. Ornamental bog gardens:
    1. Extension of the water garden; bog garden linked to a pond; overflow bog garden:
      • Created within the perimeter of the water garden by using a permeable retaining wall to confine the soil and separate it from the open water of the pond.
      • Extension of pond liner and creation of barrier lets water permeate the soil but prevents soil from falling into the pond.

    2. The independent bog; oasis garden; damp garden; irrigated bog garden:
      • Created by underlaying the bog garden with a non-permeable membrane that slows down the movement of water through the soil.
      • Made with liner independent from pond allowing greater flexibility in siting and shape.
      • As liner is completely covered with soil and not exposed to deterioration from ultraviolet light, cheaper materials like polyethylene can be used.
      • No water level to be maintained as in a water garden, so construction need not be watertight; perforation of liner fabric recommended to prevent stagnation and anaerobic soil.
