2025 Summer Update

 The Spring of 2025 seems to have just flown by and in a couple of weeks we will welcome the official start of the 2025 Summer season with the Summer Solstice on Friday 6/20/25. Before this date we have a couple of big events to prepare for and then afterwards we have some planned turf conversion areas to develop just ahead of our summer fairway aeration week where the golf course will be closed. Below are some pictures highlighting some of what we have been up to in GCM as well as our plans through the first part of the Summer of 25.

Upcoming Summer Golf Course Maintenance Schedule Overview

June 9 through June 22 - Prepare and Host  MacKenzie Cup & California State Amateur

June 23 through July 6 - Prepare select areas on golf course for turf conversion

July 7 through July 11 - Aerify & Sand Topdress Hybrid Bermuda Fairways. Golf Course Closed

GCM Activities Spring of 2025

Springtime is always a busy time on a golf course as everything starts growing at once. One of the things that we've been working on in addition to mow, mow, mow is adding more sand to our bunkers. Adding a little sand to bunkers here and there is a normal maintenance function, however our bunkers needed some substantial sand refreshing since the 2021 renovation and we are just about finished.

Our driving range mats are scheduled for replacement on Tuesday 6/10/25. Invited Clubs has switched golf mat vendors to Fiberbuilt Golf. Predictably our concrete pad was to narrow by a few inches to accommodate the new Fiberbuilt Mats, so we had to add some concrete to existing pad. 

Our strategy of late has been to lay off projects Spring through the first part of Fall and concentrate our efforts on course maintenance but we couldn't help ourselves and installed a block of sprinklers along the rough edge on the left-hand side of #12 in May.

I've been mentioning this irrigation work ad nauseum because it is the infrastructure improvement that has been proven time and time again to produce the greatest results on this property. Any opportunity we have to check one of these areas off our Master Plan we will typically move on it even though the timing was not part of our overall spring through summer plan.

This is the rough between #15 & #13. If you can recall what this rough used to be like and what it is like today, it is because we now have supplemental irrigation heads surrounding it which has improved irrigation coverage and control allowing us to maintain cool season rough right next to warm season fairway turf facilitating the very different irrigation needs of both areas.  

We have deep spiked / aerified the greens along with associated sand topdressing a couple of times since the beginning of spring and the process is helping with rooting and firming of the greens and has kept with the small hole but frequent cultural practice strategy on our greens. Here Enrique is using a Vertidrain Aerator to spike 1/4" holes 8" deep into the surface.

GCM Planned Activities Summer of 2025

Part of our Master Plan is to convert some chronically bad areas on the golf course from cool season turf to warm season Santa Anna Hybrid Bermuda to facilitate cart traffic in certain entrances and exits on the course. These are areas that are adjacent to warm season turf that have never been right.

Hybrid Bermuda can only be established vegetatively or by live plant sprigs or sod. There is no seed for hybrid bermuda. We have a couple of weeks before we aerate the fairways after the Mac Cup and the CA State Amateur. Using the fresh cores from the fairway aeration process will be great way to establish hybrid bermuda, we just have to prepare the areas beforehand. 

Above is the drive off area of #13, a chronically bad traffic pinch-point. Our plan is to strip this area, condition the existing native soil with sand and compost, compact and grade then cover with fresh aeration cores. This has to be done in the summer when hybrid bermuda is actively growing. More details to come on this great opportunity to improve some chronically bad areas. 

Another area we plan to address with aeration cores is the narrow strip of rough along the cart path on #9.

Above is an area we plan to address with aeration cores as well.  It is the drive on to the fairway #12. Another area we will address which is not pictured is the drive on to #15 right after you cross the bridge.

Another part of our summer re-grassing strategy is to prepare a few select small areas for seeding in the early fall which require some weed eradication first.  The above photo is of Dallisgrass, a notoriously difficult perennial weed to control selectively, or by using a product that will kill the dallisgrass and not the desirable turf. It can overwhelm an area to the point where a scorched earth tactic is the most appropriate way to eradicate it. 

Dallisgrass is a perennial weed that goes dormant in the winter then comes back with a vengeance in the summer by way of a very robust root system. To eradicate the weed for good you have to kill the root system so multiple treatments are recommended so the areas we plan to address will remain bare until we seed them in late summer - early fall.

This area behind #15 tees is out of play and completely infiltrated with dallisgrass. We plan to treat this area  multiple times and afterwards seed with Tall Fescue in the late summer. Other areas we plan to address in this manner are the back slope behind #1 green and the left hand rough of #12 near the pond. All of these areas have a substantial amount of dallisgrass infestation that needs to be eradicated.

Getting Through the Summer of 2025

How Members Can Help

This is the left hand rough edge of #16 and it highlights one of the main challenges Granite Bay faces in the summer post 2021 renovation. We converted half of our golf course to Santa Anna Hybrid Bermuda and the rough remained primarily a blend of cool season turf grass varieties because of the shade issues associated with our tree lined holes.  These cool season turf areas are very susceptible to the heat of the Granite Bay summers.

How can you help? The best way to help the course in the summer when operating a golf cart is entering and exiting though the gates and drive exclusively on the short cut fairway turf avoiding  the rough with cart traffic.

To protect the rough, we do plan to close a few holes at a time to cart traffic during the summer months. 

Additionally, you will notice some soaker sprinklers in areas that a bit stressed. We haven't experienced any mishaps with carts tangling up or running over these hose stands yet so thank you. 

Something to note is that the areas you notice these hose stands are areas that are outlined in our Granite Bay Golf Course Master Improvement Plan so one day there wont be such a need for hose-stands or as many cart restrictions in the summer.

Back to this image of the rough between #13 & #15. This is the goal for the entire course. Healthy cool season rough with its irrigation needs being met coexisting right next warm season fairway turf with it distinctively different irrigation needs being met. We are not that far away.

Thanks for your support!

Spring is in the Air

 GCM has had a very successful late 2024 and 2025 winter project season this year with the absence of any tree tumbling storms. We were able to check off many items from our GBGC Master Improvement Plan from cleaning up the back of #7 Green to irrigating and planting shrubs in some very bleak parking lot landscape beds. 

Once we got through some weather around Christmas, we were able to make substantial progress on supplemental irrigation install on Holes #2, #15 & #12. All of these areas in the rough have been perennially bad in the summer and the cool season turf will now have a fighting chance. These supplemental irrigation blocks have only worked every time we have installed them here at GBGC so we are confident these areas will be much better this summer.

Now that Spring is in the air, we have to shift gears to cultural practices on the golf course. We have been aerifying rough the week of March 3rd through March 7th and will have some more to do next week. So ahead of some forecasted weather on Wednesday 3/12/25 we plan to spike and topdress the greens as well.

Spiking Greens

On Monday 3/10/25 we plan to spike and topdress the greens keeping in line with our small, but more frequent aeration events throughout the year. These aeration events are designed to keep putting surface disruption to a minimum year round avoiding  traditional large hole aeration in the spring and fall. This accomplishes the desired goals not disrupting putting quality for extended periods of time and mitigating poa annua encroachment by not giving it a chance to get going in larger aeration holes. Below are pictures of the process that we will conduct on Monday.

Step #1 is to aerate with the Procore 648. We are using a coring tine this time around to actually remove some organic material from the green. Weather is forecasted partly cloudy and in the upper 60's, perfect weather for this process. 

Aeration holes are small. 1/4" in diameter maximum if that. The small hole combined with 2"X2" spacing will recover rapidly and will not deflect ball roll leaving putting quality intact especially after we thoroughly roll the surface's the morning after aeration. 

Step 2 remove the coring material. We basically use blowers and scoop shovels to remove all of the debris from the surfaces

Step 3 we usually mow the surfaces to remove any straggler cores that get stuck in the holes during initial cleanup. After mowing we blow the surfaces off again creating the finished product prior to sand topdressing depicted in the picture above with the ball mark repair tool. 

Step 4  we are seeding the collars. More to come in the future on what are our ultimate plans with these collars.

Step 5 lightly topdress the surface with sand.

Step 6 we brush the sand into the open holes and turf canopy.

Step 7 is to irrigate. We typically irrigate deeply after opening greens up with aeration. This deep watering brings the greens soil profile to its field capacity as well as drawing air into the rootzone which is one of the main purposes of core aeration.

Dry Start to 2025

The wet weather that Northern California experienced in late December of 2024 has flipped to dry in 2025. Mornings have been a bit frigid with a frost delay here and there, but with the absence of rain and occasional gusts of wind, the golf course has dried out and is playing winter fast and firm in most areas. The long tree shadows of winter keep some areas shady and therefore wet from December's rain, but we are getting one those Januarys where cold mornings and sunny temperate afternoons create good conditions for winter golf. These conditions are good for getting things done on the golf course as well as turf is not growing and we are not having to irrigate so can easily allocate resources to projects from our GBGC Master Improvement Plan. 

On that note, the week of January 20th GCM plans to start a multi-week project on the right hand side of #2 cart path near the green. We need to replace the curbing in this area that was damaged during the 2021 renovation. Additionally we want to do some irrigation retrofitting and some sod work. When doing this work, we plan on occasionally re-routing Member cart traffic in front of the green to the left had side, then over to a forward position on #3 tee. This occasional detour will start Wednesday 1/22/25 after the MLK Holiday along with back nine starts with the hope of  creating less inconvenience to the Member during our activities in the area. We estimate this work will take us through the first part of February. 

Above shows the damaged curb and the area we plan to start working on the week of January 20th. 

The detour will be delineated by simple cart directional signs. Cart path will be coned off at this juncture and the detour will be pretty hard to miss.

The forward location of #3 tee wont be much different for the pebble tees (green) but clubs will be paired with the pebbles and Granite's and Tournaments will be paired as well at about 25 to 30 yards shorter then their normal placements. 

Granite and Tournament tee markers will again  occasionally be located around the 136 yard marker on #3 when we detour cart traffic around the left hand side of #2 green during some repair and retrofitting work on the right hand side of #2.

Recent Birds of Granite Bay Golf Club

Granite Bays resident bird expert, Michele McCormick was out on the course when we were closed on Tuesday 1/21/25 and shared that she has been sighting some rare birds for our property that are starting to make GBGC their home we hope. Below are some stunning examples of Michele's work right here at GBGC.

Happy New Year

Happy New Year Granite Bay! 2025 is here and we in GCM are looking forward to another year of progress on the golf course and grounds. 2024 was a successful year for us in golf course maintenance and we look to build on that success in  2025 by continuing to work on infrastructure projects that are part of our golf course master plan. 

The end of 2024 was on the wet side but nothing too historic or alarming as December has been the wettest month of the year on average for the past 20 years. Its hard to stay productive when it is wet and rainy but we are able to make progress nonetheless. 

The pair of Swans that left us this fall returned home on January 1, 2025. This will be the third season they have  nested here assuming they are planning on staying. We did have a lone Cygnet survivor from  the pairs 2024 spring family who remained here until just a month ago after her parents left  in the fall. We believe the lone survivor is a female and just recently left we assume to find a mate.  We are hoping she returns with a mate. 

After the 11th of December it started raining and seemed like it never stopped. Seventeen out of the remaining 20 days of December we measured some precipitation. Much of the rain during the holidays was light but  the associated cloud cover, mist & fog kept the golf course wet.

As you can see from the above historic rainfall data that has been produced by our GBGC Weather station, December of 2024 was slightly below the 20 year December average. 

The only significant rain events were on the 12th and 14th which produced conditions like above which rapidly dissipated once the rain stopped. The rest of the rain days were light.

So what does GCM do when it is raining like this? The staff rarely works a full day when the weather is this stormy but there a some tasks we can accomplish such as filling divots which is what they are doing above.

Another task that can be accomplished is spreading bark in large landscape beds.  

The lighter rain events during the Christmas Holiday week kept the golf course wet without oversaturating it. So when we did get some clear weather with some sunshine on 12/31/24 through 1/2/25, we were able to get out and use small mowers (triplexes) on the fairways to clean them up. Here we are doing just that. We are not mowing much grass as the Hybrid Bermuda is not actively growing in the depth of winter, but just cleaning up and smoothing out the surface. We have to be careful and avoid soft wet areas, but have found this process to be a BMP for this year round golf course that gets played on in all kinds of conditions.

We were fortunate that these December storms were mild and dident result in the tree loss we experienced over the past two seasons. The only tree that toppled was a non-native oak tree that was planted some years ago across the path from the #8 tee.

We were rushing a bit to mow fairways to clean them up as another storm was forecasted for Friday 1/3/25 which has materialized. After that it looks like we are in for a patch of nice weather, the kind of weather that will dry the golf course out proper.
