We will be starting the 2012 Fall Overseeding & Aerification project. we will be closing the golf course from Sept. 10 thru Sept. 18 to perform these projects. Much like last year, both projects will involve many steps, long days and fully staffed crews to get everything accomplished in the allotted days that the course will be closed.
We at the Turf Care Facility have performed many successful aerifications in the past and have created an efficient method of performing this vital agronomic practice. I have explained our multi-step process in previous blog entries and our Fall process does not vary much from that of the Spring process. The only difference in this process will be the aerification tine sizing and spacings. We will be using a 1/4in tine on 1in centers and 2.5in spacings. This will be smaller holes than the Spring process but more holes on tighter spacings. This allows a sizable amount of material to be removed. But, because of the smaller diameter aerfication holes, and allows for faster fill-in and recovery of the greens.
This will be the 4th year in a row that we will be Overseeding.
This year, we will only be Overseeding Fairways, N. Driving Range Tees, Short Game Facility, Pavilion lawn and the Team Practice Facility. The total amount to be Overseeded will be 25 Acres.
The Overseed process officially began July 19th, 2012. We applied a Pre-Emergent Herbicide to all areas that were to be Overseeded to stop any Fall weeds from germinating. This will help the Overseed, by not having any noxious weed populations competing for water and nutrients while we are germinating the Overseed.
On September 4th, we applied a Pre-Emergent Herbicide perimeter around ALL areas that are to be Overseeded to keep a nice clean edge and stop any seed from germinating outside of the areas of intention. On September 5th, we applied a PGR (Plant Growth Regulator) called Primo MAXX. This will slow down the growth of the Bermudagrass areas that are to be Overseeded. This will allow the seed a time period in which it will not be in competition with actively, and aggressively growing Bermudagrass during the germination period.
The actual "Overseeding" process will begin on September 10th and will most likely be finished up by September 12th or 13th. We are using a blend of Perennial Ryegrass that is certified blue-tag, fungicide treated and salt tolerant. It came directly from a grower out of Oregon.
Upon completion of seed application, we will begin the irrigation cycles (2mins of irrigation per station every 2 hours) until we have achieved complete germination of the seed. Once the seed germinates we will be able to irrigate less frequently and apply more volume of irrigation.
Approximately 2 weeks after germination, we will apply a 10-20-20 starter fertilizer to give the young seedlings vital nutrients involved with plant growth and development.
The first mowing will be approximately 7 to 10 days after germination, and 8 weeks after germination we will apply another Pre-Emergent application to prevent any noxious weed outbreaks in the Overseeded areas.
We at the Turf Care Facility continually strive for championship caliber conditions at Jimmie Austin OU Golf Club, and by performing a successful Fall aerification and overseed, we will have taken important steps in achieving these conditions.
