Anyone playing the club lately has likely noticed some square roped off areas of turf in the middle of #'s 2, 5, 8, 12 &16 fairways. These are trials for a potential Hybrid Bermuda Turf Conversion Club Corp is seriously considering for Granite Bay. Some of these trial plots have been in place for over a month and we are getting ready to take the ropes down and let everyone experience the durability and playability we have been bragging about with hybrid bermuda.

Hybrid bermuda will take a much lower height of cut then what we currently mow our cool season turf fairways at in the summer. With that in mind we wanted to get them cut down prior to opening the areas so they would mimic the finished fairway product when we convert. We vertical mowed, topdressed and used a heavy roller on them last week to get them prepared for a shorter cut and we anticipate actually mowing them down and opening them up the first part of August.

These trials are being conducted for our fairways for the potential fairway conversion as early as 2020, however another part of the overall turf conversion plan is converting the areas around the greens or what we refer to as green surrounds. We have already started and made a large push just this week to convert our green surrounds to overseeded hybrid bermuda. Overseeded hybrid bermuda is a combination of both warm season hybrid bermuda and cool season perennial ryegrass, the best of both worlds. The particular variety of hybrid bermuda used for overseeded sod for green surrounds is not as pertinent as it is for fairways as we will always overseed green surrounds but not fairways. We do not plan to overseed fairways because of the water use required in overseeding these large areas is hard to justify any longer in California, explaining the fairway trials to get the right variety for GBGC.
Many sports field operation's including ATT Park in San Francisco have been installing overseeded hybrid bermuda for quite awhile despite the cooler weather in the San Francisco Bay Area not being ideal for growing warm season grasses like hybrid bermuda.

These sports fields made this shift decades ago primarily for the firm playability and durability that hybrid bermuda provides. The ryegrass overseeded into the bermuda grass provides the aesthetic green color even during periods of bermuda dormancy, although the hybrid bermuda doesn't go fully dormant in the mild San Francisco climate. Eventually the ryegrass will out compete the hybrid bermuda in the Bay Area because of the lack of summer heat, but these sports stadiums re-sod on a regular basis and have found that they have to re-sod less frequently once they started using the overseeded hybrid bermuda products. I use ATT park as an example because I love the San Francisco Giants, but all sports playing fields in the Bay Area have been using this combination for quite some time.
For the summer weather we experience at Granite Bay the overseeded hybrid bermuda is perfect combo year round for our green surrounds. The ryegrass will thrive in the winter and spring and the hybrid bermuda will thrive in the summer. We can refresh the ryegrass with additional seed in the fall if need be, and the cycle will repeat itself. Our plan has always been to get some of this green surround work done prior to when we do the fairway turf conversion. So now that the trial plots are installed and weeks away from opening, we have begun strategically stripping turf to install overseeded hybrid bermuda in the surrounds.
Our plan for this summer and next is for our experienced golf course maintenance staff to remove and prepare areas of surrounds for re-sodding and our sod contractor to install the sod. Work around issues are:
- Member Play & Events
- Strategic Removal Providing Members Relief in Areas Under Construction
- Required Sq. Ft. Minimums for a Contractor Install

Sod growers and installation crews are at a premium right now so getting firm installation dates is a moving target. The areas mentioned above have been stripped as of July 25th are tentatively scheduled to be re-sodded sometime next week, the week of July 30th - August 3rd which should give you an idea of the scheduling challenges. We will just have to play these areas as ground under repair up to re-sodding and two weeks after to allow the sod to root. We will be able to walk on the sod and retrieve balls but we will ask golfers to refrain hitting off the areas until ready.

Green surround areas that we are targeting for strip and replace this summer are #7, complete #5, behind the driving range tee as well as the completion of #4 & #12. Summer throws many a challenge our way so our efforts may be a bit of a moving target as well. We'll just have to see how it goes but suffice it to say we wont be handing any of our allotted capitol sod money back. That you can count on.
