Dutch White clover (Trifolium repens) is often grown with grass because clover is able to fix nitrogen for use by the grass. The state of MN wants more homeowner to add white clover to their yards because it is beneficial to pollinators. White clover is best planted from July 25 to Aug. 15 at a rate of 5 to 8 pounds per acre. It is used as an indicator plant to identify low nitrogen levels in lawns. White clover is adapted to soils and regions, which have a constant supply of moisture. It has a very shallow root system and no drought tolerance. It does not do well in sandy soil clover tolerates mowing. It is not hardy in your area without snow cover.
