Title: Erosion controlling Groundcover for Phenix AL
Answered by: Larry Larson
QUESTION:
Hi I am trying to find a grass or ground cover to control erosion on firing range berms which are 1:1 grade on a firing range outside of Phenix City AL. Sandy clay soil, direct sunlight almost all day. Hopefully cheap to initially plant, easy or no maintenance, and self seeding. Any suggestions would be greatly appreciated.ANSWER:
Mr Smarty Plants thinks you are certainly working in the right direction to look for native plants to stabilize your berms. They certainly fit your requirements of easy or no maintenance and self seeding.
The general approach we use to limit erosion is to recommend clumping grasses or shrubs that have extended root systems. It is these that hold the soil and stabilize it against the flow of water. I’ve collected a set of previous question/answer pairs from Mr Smarty Plants that address erosion and groundcover recommendations from cities in Alabama and Georgia. In addition to the recommendations, pay attention to the methods using the Wildflower Center resources to find candidate plants and approaches.

Deer Resistant, Fast Growing Groundcover Suggestions for Georgia
Hillside Erosion Control for Gainesville GA
Here are 5 grasses from those recommended above that are relatively low and tend to clump, which means they will function well controlling erosion.
Aristida stricta (Pineland threeawn)
Muhlenbergia capillaris (Gulf muhly)
Schizachyrium scoparium (Little bluestem)
Andropogon virginicus (Broomsedge bluestem)
Two more groundcovers [Calyptocarpus vialis (Straggler daisy) and Phyla nodiflora (Texas frogfruit) ] from the above discussions are quite low and give great cover and virtually zero maintenance. They are a bit less functional at erosion control, but are an excellent zero maintenance lawnlike cover.
