Venting of greens

In an effort to dry down some of the wettest greens on the course, today we have begun a process called “venting”. One definition of venting is: “permit air to enter” which is exactly what the greens need after the 6+ inches of rain they have received over the last 12 days!

There is an abundance of black algae on many greens like # 7 below:

Using a green aerator with 1/8″ solid tines on a 2″x2″ pattern we can punch 36 holes per square foot, 3 ” deep which will allow air to enter the green to hasten the drying process. In the past we have used this process to do just the opposite, to let water in after the soil has become hydrophobic. But that’s not the case this time around.

After aerating, we will roll each green using a mower with the blade off. This will gently smooth the surface to keep ball roll as true as possible. This process is slightly more disruptive to the surface than spiking but should heal over in most areas within a few days.

At this point we only plan on doing the following 8 greens, 2, 3, 7, 8, 9, 10, 15 & 16 along with the 2 practice putting greens, as they have the most algae on them. We will be spiking the other greens beginning tomorrow. These forms of aerification along with fungicide treatments should expedite the healing process. In the upcoming weeks we will be aerating tees, approaches, collars some fairways and roughs. I will be posting information on these processes both here on the blog and on the “members only” page on the website.
