Bog garden
- 2. Bog garden • A bog garden employs permanently moist (but not waterlogged) soil to create a habitat for plants and creatures which thrive in such conditions. • It may exploit existing poor drainage in the garden, or it may be artificially created using pond liners or other materials to trap water in the area. • Any such structure must allow a small amount of seepage to prevent the water stagnating.
- 3. Cont.., • For instance, a pond liner must be pierced a few times. • Typically a bog garden consists of a shallow area adjoining a pond or other water feature, but care must be taken to prevent water draining from a higher to a lower level. • The minimum sustainable depth is 40–45 cm (16–18 in). • Good drainage is provided by gravel placed over the liner, and the bog can be kept watered by using a perforated hose below the surface.
