JHGTC Tip of the Week

JHGTC Tip of the Week

Thanks to Rick Stuck for helping out with this week’s tip.

 

When at the practice tee, please make your divots in a straight line backwards. For example:  After you hit a shot, place the ball directly behind and on the edge of the divot you previously made. See article below.

 

Practice Like A Pro

Randomly scattered divots (on the left) remove up to 50% more turf than practicing in a linear pattern (on the right) where each new shot is placed directly behind the previous divot.

Late July is usually the time when there is a lack of turf coverage on practice range tees established with cool-season turf grasses, such as creeping bentgrass or Kentucky bluegrass. Heavy play removes divots faster than the turf can recover, and hot, dry summer conditions leave little opportunity for seedling establishment or regenerative growth of surrounding turf. Poor turf coverage that comes in mid-summer generally indicates that the practice tee is simply undersized for the amount of play received, i.e. there is not enough time for turf to recover before tee stalls are returned to previous locations. It also indicates that tee stall rotations need to be reviewed for efficiency and that synthetic turf options should be considered at the rear of the tee to provide the additional time needed for turf recovery.

With the exception of an efficient tee stall rotation, enlarging the tee(s) and adding synthetic turf are improvements typically left for the off-season when time and funds become available. So, until then, what can be done? The solution resides with golfers. Since randomly scattering divots can quickly destroy a practice range tee, the better approach is to shrink one’s divots by removing them in a pattern just like the professionals. More specifically, this includes placing each shot directly behind the previous divot. This can easily be repeated for up to 10 shots resulting in much less turf being removed.

Let’s take a look at a practical example that was provided by Golf Course Superintendent Chris Pekarek at The Village Links of Glen Ellyn in Illinois. Mr. Pekarek estimates more than 2 million shots are taken annually from the 1.25-acre Kentucky bluegrass practice tee and that 1.5 million of the shots result in turf removal. Although divots come in all sizes, the average iron shot is believed to remove a divot 3 inches wide by 6.5 inches long for a total of 19.5 square inches. After just 30 shots, or a small bucket of balls, 4.1 square feet of turf are removed, given a typical practice routine (30 shots x 19.5 in² = 585 in² / 144 in² = 4.1 ft²). Therefore, after an entire season, 205,000 square feet of divots are removed from the tee. That's more than 4.6 acres of turf from their 1.25-acre surface.

If instead each shot is played directly behind the previous divot, subsequent divots are reduced to an average size of 3 inches wide by 3 inches long, or 9 square inches. After 30 shots, this pattern removes only 2.1 square feet of turf. (As the first divot removes 19.5 square inches and the subsequent 9 divots remove 9 square inches each for a total of 81 square inches, a total of 100.5 square inches is removed for every 10 shots, which is typical for this linear pattern. For 30 shots or a small bucket of balls, 3 x 100.5 = 301.5 in² / 144 in² = 2.1ft² are removed.) If everyone adopted this method, the annual number of divots removed would be reduced from 205,000 square feet to just 105,000 square feet. That’s nearly a 50% reduction in the amount of turf removed.

Implementing this simple divot pattern into your practice regime has significant season-long implications at your facility. So, rather than voice a complaint about the turf during oppressive conditions in July and August, do the turf a favor and practice like a pro!

Dear Membership,

The summer just continues move forward with no end in sight.  We had our first short frost delay this morning as the temperature on our weather station got down to 37 degrees..which is closer to 34-35 degrees on the course.  Looks like we may experience a little harder freeze on Friday night.  This signals, as we all know, that fall is just around the corner and those beautiful blue bird days with highs in the 60’s and 70’s aren’t far behind.  I appreciate everyone’s patience with the frost delays that will soon be upon us, and rest assured we will get everyone out as quickly as we can on those mornings. 

Thursday we are hosting our half of the Snake River Cup…GO JHGTC!!  After years of holding on to the cup we have let the Pines “borrow” it for a couple of years and it’s time to have bragging rights back on “the east bank”.  Good luck to all those that are competing and thank you for representing the club.

The big news on the course recently has been the increase in activity of bees, both on the course and around the clubhouse.  We have been putting up bee traps around the facilities and have gone through several cases of spray around the course.  That being said we are guests in their environment and as long as you aren’t aggressive with them they will tend not to be aggressive towards you.  We will continue to try and manage the situation keeping in mind that bees are the baseline for all living plants as they account for a significant percentage of all pollination that takes place on our planet.  Interesting fact: 1/3 of the food we eat in America comes from pollinating insects such as bees.

The golf course continues to play wonderfully and I am looking forward to cooler days so we can see some healthy growth on the course.  I want to thank everyone for continuing to use cart paths where available and not driving around approaches, greens and tees.  It is very easy to see what the compaction does to playing conditions..good example is the right side of #3 between the bunker and the cart path.  All the driving and parking in that area has made keeping healthy turf almost impossible.  You can see improvements in areas we have put signs and ropes.  Good example of that is to the left of number 12 green..you can see how the area just next to the bunker has improved and the difference in turf quality where carts are exiting the fairway further up to the east.  I appreciate everyone’s help in their travels around the course.  Have a great week.
