How can a footprint be a killer?
When it's a footprint made on a putting surface that's
covered with frost. It may be hard to believe that simply walking across a golf
green covered with frost can cause so much damage, but the evidence will be
there in a few days as the turfgrass dies and leaves a trail of brown
footprints. That's why most courses will delay starting times until the frost
has melted. And it's also why golfers who appreciate a quality putting surface
will be patient during frost delays.
Why does frost cause problems?
The putting surface, or green, is an extremely fragile
environment that must be managed carefully. Remember that every green is a
collection of millions of individual grass plants, each of which is a delicate
living thing. Obviously, Mother Nature never meant for these plants to be
maintained at 1/8 or even 1/10 of an inch for prolonged periods. This stress
makes greens constantly vulnerable to attacks from insects, disease, heat,
drought, cold -- and frost.
Frost is essentially frozen dew. It can form when the
temperature (or wind chill) is near or below the freezing point. The ice
crystals that form on the outside of the plant can also harden or even freeze
the cell structure of the plant. When frosted, the normally resilient plant
cells become brittle and are easily crushed. When the cell membranes are
damaged, the plant loses its ability to function normally. It's not much
different than cracking an egg. Once the shell is broken, you can't put it back
together.
The proof is in the prints
Although you won't see any immediate damage if you walk on
frosted turf, the proof will emerge within 48 to 72 hours as the leaves die and
turn brown. And, since just one foursome can leave several hundred footprints
on each green, the damage can be very extensive.
Thanks for understanding
The damage isn't just unsightly -- putting quality will also
be reduced until repairs are made. Those repairs are time-consuming and, in
extreme cases, the green may have to be kept out of play for days or weeks
until the new turfgrass is established. A short delay while the frost melts can
preserve the quality of the greens, prevent needless repairs and may even save
you a few strokes the next time you play.
