We have begun our winter weed treatment program. We are
making spot treatments on tees and fairways.
As we discussed in December, we wanted to wait a little
later into the winter to begin spraying
weeds. Although the Bermuda grass has been brown and visually dormant for a
long time, it can actually take much longer for the very deepest parts of the
plant to harden off.

Although the temperatures can swing wildly, the actual main
driver of dormancy is soil temperatures. And the soil temperatures do not fluctuate
like the air temperature. The soil temperatures have been steadily dropping
since the fall and we are now well into a safe time to begin our applications.
Last week we started our tee and approach applications.
These will take place over several weeks because we must do it with a backpack
sprayer. The tees are too small and confined to work with our big 300-gallon
sprayer, especially considering that anything that gets sprayed will die. We
can’t take the chance of accidentally spraying the rough around the tees.
We also started and completed the spot spraying of fairways.
This process consists of driving our large sprayer up and down the fairways,
but only spraying where weeds are present. This is a very targeted and
efficient application, which uses a very limited amount of chemical.
Prior to the Bermuda grass damage sustained in the winter of
2017/2018, we were nearly weed free in all Bermuda grass and had not made a
winter weed application in 2 years. Starting with this winter’s treatment, we
are working to get back to a clean slate.
Etiquette Reminder of the Month
Please do not try and remove a flag stick that is frozen into
the cup. Turf damage may occur.
Also, as part of a Golf Committee initiative to improve
course etiquette, we have included links to videos teaching proper on course
etiquette. Please take a moment to watch:
See you on the course!
