Thanks for the question.

My first impression is that it will be quite difficult to establish any type of turf on this slope. Besides the exposure to sunlight, the soil on this slope is probably sandy with little water retention. You should think of an alternative as it seems you are doing. At the following site, pay special attention to page 34:

As described at this site, various types of junipers might look attractive.

A similar question was submitted to us in 2008 from an individual living in Woodbury. This was our response then:

“QUESTION:

I live in the Twin Cities of Minnesota. I have a steep slope in back yard which gets considerable rain runoff from the homes above me. What plants/shrubs/trees could I plant on the slope to stop the erosion occurring? I've had it hydroseeded, but the rills keep appearing from the water. A line of plants at the top of the slope to dissipate water?

ANSWER:

It sounds as if you could benefit from erosion-control blankets and/or fiber or coir rolls to stabilize your slope. The fiber rolls and erosion-control fabric work by slowing the runoff water and allowing sediment to fall out rather than be washed away. Seeds are sown under the erosion-control material and grow up through the matting when they germinate. Underneath the matting the roots of the plants growing through the erosion-control material anchor the soil to stop the erosion. If you use erosion-control blankets made of biodegradable material, they will eventually disappear leaving the plants to control the problem. Grasses are an excellent choice for erosion control since their extensive fibrous root system is very effective in holding the soil in place. Here are few attractive native grasses and sedges that are commercially available and grow well in Minnesota. With the exception of the Canada wildrye which can reach 4 feet, all these grow less than 3 feet tall.

Bouteloua curtipendula (sideoats grama)

Bouteloua gracilis (blue grama)

Bromus kalmii (arctic brome)

Carex pensylvanica (Pennsylvania sedge)

Elymus canadensis (Canada wildrye)

Koeleria macrantha (prairie Junegrass)

Pascopyrum smithii (western wheatgrass)

Schizachyrium scoparium (little bluestem)

Sporobolus heterolepis (prairie dropseed)

A problem with answering a question such as yours is that my response will present you with a whole host of possibilities from which to choose. To reduce the number of possibilities, visit a few gardening centers/greenhouses with a list of plants in mind and look at them directly. Of course call ahead of time to see if they have such plants in stock. A better way of deciding might be to visit the Minnesota Landscape Arboretum where a large number of plants suited for steep slopes are actually growing. See:

As a last resort, consultation with a professional landscaper can be a wise decision. See:
