Frost is a common reason for morning tee time delay. The reason for the delays is the damage that can occur from foot or equipment traffic to the turf when frost is present. Generally speaking, nice fall golfing days and frost go hand-in-hand. With more frost days expected, this is a good time to look at the conditions favorable for frost.
Frost itself does not cause damage, but injury does occur with traffic on frosted areas. Turf damage is generally superficial. This is not to say that traffic should be allowed on frosted turf. If traffic occurs, whether it is foot or mechanical, damage caused by crushing the leaf blade will occur. Initially the symptoms will appear purplish to black in color (almost like an excessive Iron application). The damaged turf will then progress to a straw color. If no damage occurs to the crown, recovery will occur from the generation of new leaves.
