Living In Midwest With A Neighbor That Has A Pump In The Middle Of His Yard.

Question

During heavy rains he floods my yard and the back end which slopes downward erodes at the grass. Is there a stronger grass to hold against the flooding?

Answer 1

Bahia grass, ryegrass, and rough stalk bluegrass tolerate wet soils. They perform best in shade, but you didn't mention whether the site was in sun or shade. This would be a good question for your local extension agent, who will know which grasses do well in your area.
