Topic: Erosion Control
Title: Native plants for erosion control in Cataula GA
Answered by: Barbara Medford

QUESTION:

I have several steep embankments on my property that are slowly eroding. What kind of plants (other than grasses, the area is not lawn mower accessible) can I plant to keep this from happening? We have very hard red Georgia clay!

ANSWER:

Ah, but didn't you know that the best erosion control IS grasses? And that there are a number of grasses native to Georgia that don't even want to be mowed? They are attractive, varied and will hold their place all year. And, more important, their long fibrous roots will hold the soil on your embankments. A very similar answer to yours was answered just a few days ago, and rather than repeat ourselves, please read this previous answer. Granted, you are in Georgia, and the previous question was from Nebraska, but we will search in our Native Plant Database for grasses native to Georgia and tolerant of clay. The previous question involved mostly seeding grasses, but you can also purchase plugs to be planted directly into the hillside. Go to our Native Plant Suppliers section, enter your town and state into the "Enter Search Location" box, and you will get a list of native plant nurseries, seed companies and landscape and environmental consultants in your general area. You should be able to find sources for what you need and help with doing it, if you so desire. Another source closer to home for information on erosion control in your area is the University of Georgia at Athens Extension Office for Harris County. They may already have bulletins or plant lists tailored to the problem you are having.
