The traditional grass that adorns most lawns has a shallow root system that is not equipped to properly infiltrate water. Replacing part or all of your lawn with an alternative seed mix such as fine fescues, low-growing flowers, or native grasses can be the solution. These deep-rooted plants are better infiltrators and also hold soil in place, preventing erosion. There are many types of sustainable lawn seed mixes, including mixes aimed at butterflies or pollinators. Your lawn can change from a slab of “green concrete” to a multi-purpose BMP.
