Plant selection depends on individual taste and what would best suit the area. As a general guide it is recommended that slopes be planted out with 4-6 grasses or ground covers per square metre. Trees and shrubs should be planted as they would in a normal landscape design.
To maintain the look and function of the site it is necessary to actively remove any weeds that appear, especially in the first two years of the site’s development. This will give the plants the greatest chance of survival and will promote the bank stabilisation. After the first couple of years the plants will have grown sufficiently to compete with any weeds that may appear. The site can then be treated in a similar fashion to any other garden bed and weeded in the same manner.
If the site is highly infested with weeds prior to planting it is recommended to use a herbicide to clear the area prior to planting. Alternately, plant only grasses and trees to begin with, then carry out spraying with broadleaf selective herbicides. Once the grasses have established and the weeds have been controlled the herbaceous plants can then be planted.
