Velocity

As we draw closer the the end of the 2024 golf season and start of the Swope Renovation there have been several pre-emptive steps taken to insure the success of upcoming projects. An issue we have tackled in the month of September is beginning to eradicate any poa-annua from our rough. This is a crucial process that we had to insure happened before the renovation of our greens and tee complexes as to prevent any contamination from the rough onto newly seeded areas.

To eradicate the poa-annua in our rough we implemented multiple applications of Velocity(Bispyribac-sodium) in late August/September. You will see in the images below how effective it was at taking out any existing Poa and leaving room for our new rough seed to germinate and thrive.

Once the Poa has been suppressed we were then able to seed into the soil with new cultivars of seed that will help increase not only the playability but the overall health and longevity of our rough at Swope Memorial.    

                                                            

New Nursery

 As we draw closer and closer to the start of the Renovation at Swope Memorial there are several inhouse projects that we are breaking ground on. This month was crucial in timing out the expansion of the existing bentgrass nursery. Currently our bentrgass nursery to the left of 12 fairway was roughly 1200sqft. This is considered small and would not be appropriate for the amount of bentgrass we will have post renovation. We therefor expanded the nursery to now be over 3600sqft.

 

During this process we removed existing turf and material surrounded the the existing green. We then created new drainage lines to properly move water across the entirety of the new nursery.

 Additionally we added a new layer of sand/peatmoss mixture to give the new seed a solid foundation to grow into. Lastly we laid pre-plant amendments to properly feet the seed that was soon to follow.

                                                                                    

 As you will see the bentrgass has already begun to germinate and is looking great!

                                                                                

Hospice Care

 The dog days of summer are officially here at Swope Memorial. With highs reaching into the hundreds and overnight low's barely dipping into the 70's if not low 80's its a miracle any turf can survive these Midwest summers. With the weather patterns we have experienced in late July its not a matter of if the turf will start to die its a matter of how slowly it will happen. Our jobs as Superintendents becomes similar to a hospice nurse during these times. Creating the best possible environment to keep the turf comfortable to prevent unnecessary death.

 As a golfer this will present itself to you as seeing more maintenance staff watering greens during the day. Greens moisture levels become even more important during a heat wave because of the anatomy of our Bentgrass/ Poa greens. Bentgrass is less susceptible to the heat but still needs constant monitoring because of its longer root zone allowing for it to reach down and collect moisture at lower soil depths. Poa on the other hand has an extremely shallow root zone only allowing it to collect water at the top 2 inches of soil. This inability to collect water is why you will see our maintenance crew doing constant moisture checks on the greens to insure we lose as little Poa as possible. You may also notice slightly longer rough and fairways to give the turf a chance to protect itself. And as always stricter cart traffic rules that stave off rough death from over traffic.

Gas Exchange

What are you all doing to the greens today? This question seems to be asked a hundred times a season between our members, staff, and once a year players alike. As superintendents green's health is always on the forefront of our minds. Luckily with continued innovations in the turf management industry we have a plethora of tools in our toolbox to manage not only turf health but playability as well

Many of you this week likely saw our Turf Team venting the greens before play on Monday and Tuesday. Now what does venting do and why is that important? Our venting process as Swope this week involved using "pencil" tines to penetrate roughly the top 4 inches of our greens. Each hole is spaced out 3 inches from the previous and this is continues over the whole green. Now why is this important? Venting is crucial for gas exchange to happen for the plant. Without venting soils can become to compacted to allow proper gas exchange and will also affect water retention.

Why Vent?-  Along with the health benefits of venting the greens there is also a huge benefit in the playability of the greens after a vent versus a full aerification as we do in the spring and fall. After venting we are able to roll the greens and add a light layer of top-dress sand. This combinations is very non aggressive and keeps the greens much smoother than after a normal aerifications.

The Best is Yet to come

 What an interesting month May proved to be here at Swope. Once again Missouri weather will keep you on your toes. May brought us some unfortunately unexpected high temps, but also blessed us with an exceedingly large amount of rain and thunderstorms. 

 

One perk of the job here at Swope is it should never be boring and monotonous. One day you can be dealing with keeping greens alive during scorching temps, and the next you can be pumping out bunkers from a torrential rain fall. May brought the best of both worlds to us and a little more.

During May we also got to lay zoyzia sod on many of the tee boxes that struggle each year. You will notice new sod on number's 5,6,7,11,12,16 tee boxes. This has become a yearly occurrence due to the number of rounds played at Swope each season. With rumors of a renovation this will be an issue we plan to tackle head on to create both the best playing conditions as well a sustainable management practice.
