The gravel path in the butterfly flight area can be the same as in the plant recovery zone. The plant beds need to be de-turfed and dug down about 45cm. Depending on the quality of the soil, it may be necessary to add compost to the beds to enrich the planting areas. Access to water from a tap or standpipe will be needed for this area and the plant recovery room. This can be external and piped in using a hose pipe.
