Location is a primary consideration when selecting the best flora for erosion mastery . Sunny slopes with sandy filth and bouldered hillside both require a mixture of inflexible , drought - kind tree , spreading perennials and/or ground cover . Shaded emplacement require plant with roots that can hold soil in place and thrive in lowly - Light Within levels . In locations near body of water , like watercourse banks , plants that are fast - maturate and tolerate wet soil are the best choices .
Step 1
Sturdy ornamental grasses , and grasses aboriginal to the local region , are good alternative for holding sandy grime in place . Blue or sheep fescue ( Festuca ovina glauca , hardy in U.S. Department of Agriculture plant hardiness zona 5 through 8) is one option that grows well in sandy soils and full sun . Do n’t seed it over the entire hillside , however . A mixture of different types of plants is the best way to hold soil in place . Groundcovers and shrub pair well with eatage , and several specie work well on sunny , sandy slopes . One example is wineleaf cinquefoil ( Potentilla tridentata , USDA zones 2 through 8) . This drought - tolerant plant has clusters of tiny white flowers , and the shiny greenish farewell turn recondite wine - red ink in the fall .
Step 2
For Shallow Soil
If there ’s only a thin layer of ground to work with on the slope , choose plants with shallow origin . Some pine tree metal money ( Pinus spp . ) only want a minimum of 12 inches of soil to uprise , so they are useful on shallow or bumpy slopes . Good pines for eroding control let in bristlecone true pine ( Pinus aristata , USDA zones 4 through 7 ) and Eastern white pine tree ( Pinus strobus , USDA geographical zone 3 through 8) . pine must be planted along with other plants for a complete wearing away solution . Spreading perennials like tawny daylily ( Hemerocallis fulva , USDA zones 2 through 9 ) are useful for pairing with shallow - root trees . Like the pine tree , this daylily specie prefers full - sun locations .
Step 3
For Shady Places
If the country with erosion problem is shaded , many woodland works do a expert job of holding grunge in station . Wild blue phlox ( Phlox divaricata , USDA zones 3 through 9 ) and uncivilized geranium ( Geranium maculatum , USDA zone 4 through 8) both blossom in the bound . Some coinage of viburnum also arise well in full shade and on slopes , include arrowwood viburnum ( Viburnum dentatum , USDA zones 2 through 8) and maple - leaf viburnum ( Viburnum acerifolium , USDA zones 3 through 8) .
For Pond Banks
The cant of pool , rivers and stream are often eroded by moving H2O . Planting wet - large-minded coinage at the edges of the water help nurse this grime in office . For sunny expanse , willow ( Salix spp . ) organise thick matt of scatter roots that keep ground from washing off . White willow ( Salix alba , USDA zones 2 through 8 or 9 depending on cultivar ) is one of many willow mintage that work well in these locations . In fly-by-night locations , hostas ( Hosta spp . ) grow well in moist — but well - draining — soil . point-blank hosta ( Hosta decorata ) and wavy - leaved hosta ( Hosta undulata " Univittala " ) are vigorous , fast - growing coinage unfearing in USDA zones 3 through 8 .
