Pictured above here is an up close look at frost. Normally in our area frost can occur anytime between the dates of Oct. 15th and April 15th of each year.
This picture illustrates why we do not allow golfers out when frost is present. While the plant is in this frost mode the cell walls are frozen and will rupture and die when stepped on. The foot imprints illustrate the rupturing of the plants cell walls.
Turf damage from a foot print on a green while frost is present.
Although this turf damage will recover in the coming months, this creates an opportunity for POA ANNUA invasion along with other weeds.
