Last week we put the finishing touches on the practice area by laying out 200 bushells of Tiffway II Hybrid Bermuda sprigs. This was the culmination of four weeks of work where we transformed the area by enlarging the target green and softening or flattening all usable areas around the green.

Additionally we removed the left hand bunker when looking at the green and made two more usable bunkers, one shallow and one deep, out of the large bunker on the right. As I mentioned in a earlier update, the vision for the changes to the area are the result of Craig Johns countless hours of thought on how to make this area more usable. The goal was to make a functional area to practice as many representative Granite Bay short shots in the limited space we had to work with and I think the collaboration worked. Once opened, I believe the members who use the short game area will find it much more practical and hopefully the area will entice members who never used the area prior.

The decision to get a base of hybrid bermuda established in the area was mine. I believe the durability that hybrid bermuda provides particularly in the summer months will be a great advantage to the area. We will overseed it with ryegrass in the winter so it will always be green although hybrid bermuda is not like its grandfather common bermuda. It's much finer textured, does not go dormant as early as common and greens up much earlier. It is the grass that is on most of our tees and will be on all of them by the end of this golf season.

The project is right on schedule if you recall the construction goals we set earlier in this blog. Week 5 was when we planned to sprig the area and seed the green and that is exactly when we did it. For the next 5 weeks we plan to push the grow-in of the hybrid bermuda and then overseed with ryegrass. Next we will let the ryegrass establish for another 4 weeks and then the area will hopefully be mature enough to open. If it is not mature enough, we'll let it mature a little more. Our initial 13 week construction goal's were to re-open in mid October and that is still the goal, however we will not jeopardize the work and investment that has gone into the area by opening too soon so we'll just have to see how it goes.

Speaking of the Tees
Another goal that we have not really talked about much this year is the continuing resurfacing of our tees. This project hat was started over ten years ago will be completed in the coming months as we only have seven of tee surfaces left to do. We will be completing the tournament & club tee on #2 this week and will be working on the cobble / combo tee on #2 along with the pebble & nugget on #4 over the next couple of weeks.

Putting Surface Progress
Our greens are progressing nicely due to the aggressive core aeration we started almost a year ago and plan to continue this coming October. The turf is maintaining a root depth and the soil profile is void of the anaerobic black layer that sporadically developed last year and caused us problems. Our only issue has been with the sod we installed at the back and front left of #7 & #14. These areas started drying out much more rapidly then the rest of the green after the rain stopped this past spring. We determined that we made a miscalculation in amending the soil underneath the sod last year when we replaced it. The soil was too dry and hindered deep root development. This forced us to mow the areas with a different mower at a higher height of cut and spike and amend the soil profile by brushing in amendments from the surface to encourage proper rooting. It never has been or is our intention to reduce the size of these greens. We are actually starting to mow these areas down now and should have them at normal greens height in the next few weeks.

has allowed turf to properly establish and is now being gradually brought down
to the same height of cut as the rest of the green.
We will be core aerating the surfaces aggressively again this fall albeit earlier in October so I do not anticipate any recovery issues. After this forthcoming aeration we will have removed over 30% of our greens surface area since last fall. This is definitely a recipe for success as I am sure will be confirmed by physical soil testing slated to be performed later in the year.
These "Dog Days" of summer are the times that try greens keepers souls. Along with fighting dry spots it is not unusual to fight more wet spots at this time of the year then in the winter when it is raining. You might ask why? Its probably a combination of things from our unique cacophony of turf types, (at least for our area) to the heavy native decomposed granite soil beneath it. The weather has been fantastic for summer but it still is summer with its long days and higher then ideal temperatures for cool season turf. And I believe up until recently we have been able to avoid many of the overly dry and overly wet areas on the course by a stepped up hand watering and irrigation management regimen. But now we seem to have saturation in some typical areas that just need some drainage attention. We have a area near the 100 yard marker on #12 and another about 175 yard out on the right of #4 that we have slated for some drainage work in the coming weeks.
A pretty good synopsis describing the details of Why We Get Wet in the Summer is a good reference specific to Granite Bay Golf Club for these "Dog Days". Its short, has a lot of pictures and explains some of the history of our turf.
Course Etiquette and Traffic Control
Filling divots and fixing ball marks fall into the realm of golf course etiquette that should be automatic to all of us who play golf. It is one of the first things that we teach our children learning to play even before the details of the golf swing. The Granite Bay golf committee and board of governors have and will continue to push initiatives to to change habits amongst all of us who play the course to take ownership by stepping up our efforts in ball mark repair and divot filling. My observation is that these efforts have helped and I hope will continue to improve.
If there was ever a time of year that these efforts would be more important it would be now. Our golf course will always be at its most stressed out point in August and September. Anything that we can do to further its inevitable upcoming recovery would improve and expedite good conditions this fall.
|Unfourtunatly not an uncommon sight when tires of any vehicle|
travel on stressed turf. Avoiding driving on brownish or grey in color
turf in the afternoons can really help minimize this ugliness.
Divots and ball marks are one thing but vehicle traffic, carts and maintenance equipment alike, will cause more damage to the course then anything else I can think of. Please use the cart paths and walnut shells whenever possible and avoid obvious stressed out turf areas. These areas can be identified by brown or grey color to the turf particularly in the afternoon. It is a different golf course from morning to afternoon especially this time of year as we tone down the irrigation to keep from getting too soft.
Thank you for your support and efforts on this front.
