Care Guide

Watering

Water 1-2 times a week depending on rainfall, providing about 1 inch of water total

Fertilization

Apply nitrogen-rich fertilizer in early spring as it breaks dormancy. Fertilize primarily in fall for best root development.

Grass Clipping Tea:Steep fresh grass clippings in a bucket of water for 3 days, strain, and dilute 1:1 with fresh water. Avoid using clippings treated with herbicides. Odor can be strong, so use outdoors.
Pruning
  • Mow regularly to a height of 2.5 to 3 inches to encourage deep rooting and shade out weeds;
  • Never remove more than one-third of the leaf blade in a single mowing;
  • Leave clippings on the lawn occasionally (grasscycling) to return nitrogen to the soil.
