Can Pea Gravel Amend Clay Soil?
Pea gravel helps amend clay soil, but only to a limited extent. Pea gravel creates temporary spaces for air and water to use to reach plant roots. It does not improve the soil's structure to keep the space open. Only organic material will improve aggregation, aeration and drainage in clay soils.
