No grass, a drop, clay and erroding hill - Knowledgebase Question

Our lawn is on a new property. At the back of the garden there is a sharp run off where the earth (clay) is starting to erode. No grass has grown. Without the expense of a retaining wall, what can we do to prevent loosing the back of our garden to the neighbors? (Area is apx. 7 ft by 14ft with a gradually increasing 6ft drop along the edge.) Please advise.

If the slope is steep, turfgrass probably isn't your best choice - it would be difficult to mow. Instead, I'd suggest planting a low growing groundcover. Some to consider include: St. John's wort (Hypericum calycinum), Prostrate Abelia (Abelia x grandiflora 'Prostrata'), Ajuga (Ajuga reptans), Trailing Arbutus (Epigaea repens),
Yellow Archangel (Golden dead nettle, Lamium galeobdolon), Bicolor Barrenwort (Epimedium x versicolor 'Sulphureum'), Bearberry (Arcrostaphylos uva-ursi), Strawberry Begonia (Saxifraga stolonifera), Creeping Blueberry ( Vaccinium crassifolium), or similar groundcover. Once the plants are installed the roots will help knit the soil together and you'll lose less soil to erosion. Best wishes with your project!
