Frost
happens when the temperature of the plant is below freezing; this is why we
have frost delays when the air temperature is 38 degrees. Essentially, frost is
frozen dew. Ice crystals form on both the outside and inside of the plant. When
there is traffic, grass plants that have frost the plant tissues
actually ruptures. The damage won’t be seen right away, but the
next day the cart tracks or the footprints will appear black. This is because
that plant is dead and won’t be able to repair itself. For some perspective, just one foursome can
leave up to a hundred footprints on one green that would be a lot of dead
plants. There are certain situations
where we can water off the frost, which will essentially melt the ice that is
creating the frost delay.
