"Black Friday"

The photos below depict the physical evidence of damage resulting from foot and golf cart traffic on previously frosted turf.  The "black markings" are the signs of damaged plant cells within the leaf tissue.  When the temperatures are low enough to freeze the intercellular liquids within the plant, the plant is vulnerable to piercing damage when traffic is present.  Please respect your golf course and remain off of turgrass when frost is present.
