How to Stop Soil From Washing Out of a Flower Bed

Common causes

Beds located on a slope, beds without a solid edge or border, and beds positioned where downspouts or runoff concentrate water are all common places to see soil erosion.

Why a border or edging can help

A well-installed border helps contain soil and mulch, reducing how much washes out during heavy rain.

When grading or drainage is the real issue

If erosion is significant or recurring, the underlying cause may be how water is moving across the property rather than the bed itself. In these cases, a broader look at grading or drainage may be needed.
