We will have a frost delay this morning. Clear skies and cold nighttime temperatures make for perfect frost conditions.
Essentially, frost is frozen dew that has crystallized on the grass, making it hard and brittle. Walking on frost-covered turf causes the plants' internal cell walls to break down and rupture. When the cell walls are broken they can not be put back together, much like an egg, and the plant losses it's ability to function normally.
During frost delays, please remember to avoid walking on any turf. Thank you for your cooperation.
