The Q&A Archives: erosion

Question: we have a steep drop off in our back yard and the soil is very sandy and washes away easily. are there things we can plant shrubs or grass that will prevent this. what do you know about berms.

Answer: Some options are traditional groundcovers, such as low-growing, mat-forming junipers or English ivy (Hedera helix), or a spreading perennial such as creeping phlox (Phlox subulata). Make sure whatever you select is very low growing to maintain the sightline if you need to be able to see out of, say, a driveway. If height is not an issue you might try a fast-spreading daylily. Finally, if the slope is truly steep and in danger of eroding, consult with a landscape architect for assistance in designing a suitable retaining wall or series of terraces. Good luck with your project.
