As planned on Monday April 10th, 2023 we started aerating and sand topdressing the fairways at Granite Bay Golf Club. The plan was to aerate and topdress the front nine fairways the week of April 10th on a Monday and Tuesday and follow up with the same process on the back nine on Monday and Tuesday of the following week. On the Mondays the club would be closed and on the Tuesday's we would alternate front nine and back closures so the process could be completed in a productive manner, as well as keeping Member disruption to a minimum.
Below are pictures of the process in a somewhat sequential order for those who are interested. Additionally we have some pictures covering a deep tine aeration of the front nine greens we did while the front nine was closed. Don't worry, the process is very non-disruptive but extremely beneficial.

Putting Surface Deep Tine Aeration
The re-building process we did to our greens in 2021 is referred to as "re-surfacing" not a complete re-build. We basically removed 4-6 inches of sod and sand, replaced that with a new greens mix sand, shaped and seeded into that. The remaining 6-8 inches of old sand remained. Rooting of the new bentgrass into this older sand / greens mix is positively impacted by the presence of air. That is what this deep tine aeration will do, provide columns of air in which the deep rooting bentgrass will go.
The benefits of deep rooting are multifaceted with the main one being we can deep water the greens more effectively creating a scenario where we dont have to irrigate them as frequently. Less frequent irrigation means a firmer surface. A firmer surface means a truer, faster surface that is not as prone to ball marks. All things that we are striving for. Below are pictures of the process.
