Late Summer Post -

The cup changers "tools of the trade". At Rolling Meadows cups are moved 3 to 5 times per week depending on events and the time of year.

It is hard to believe fall is only 9 days away. From my perspective it has been a interesting season so far. The cold wet spring followed by a cool summer with ample moisture made the entire summer feel like May. Rain was common and with the exception of ten days in July when we gave the irrigation system a workout and stopped mowing the non-irrigated rough, the rest of the year was mow the course, turn around and mow it again.

Electricity costs will be down because the pumphouse was not used very often but gas and diesel costs associated with mowing are up a equal amount. In August we watered fairways once and spent most of the month praying the rain would stop so the course would firm up and be more enjoyable and mowable. A couple days each week it was too wet to mow without doing damage and the other days we played catch-up mowing all we could around the players.  

The wet and humidity along with cooler than normal temperatures allowed the turf disease dollar spot to flourish throughout the course. Usually a disease of closely mown greens tees and fairways this year it infected the roughs. It is cost prohibitive to treat the roughs due to the acreage and recovery will happen naturally when the weather conditions change. In the rough dollar spot is mainly a aesthetic problem but on greens and fairways it can reduce playability.


Above is a small area of untreated fairway (check plot) we do use to see how bad the disease would be if we did not treat with fungicides. You can see the result is not good aesthetically or for playability as a ball can sink in the lesions.

This picture shows a fairway treated with a fungicide according to the label should last 21 days on day 22. The lesions are smaller and do not affect playability. When disease pressure is low a 21 day product may last 21 to 28 days or longer. When pressure is high it may last 14 to 21 days. In this case disease pressure was high and we applied a new treatment the next day to stop the current lesions from growing and prevent any new lesions.

 

As I wrote this spring the bridge collapsed on hole 19 and with no other options to get players from hole 19 to 20 we had to act quickly. The new culvert on hole 19 has been well received and cuts off quite a bit of distance for walking golfers as they go to 20 tee.

 

The second culvert was installed in summer to replace the walking bridge of Rays Creek on hole 17 and allow a more natural flow for golfers while reducing the visibility and ball flight problems caused by the railings from the walking bridge. We still have to remove the supports from the walking bridge but for the most part the bridge replacement project is finished.

 

The plaque for Rays Creek was moved from the bridge railing to this rock placed near the culvert crossing. Ray Puddy was a long time county board member and chairman of the Parks and Recreation  committee as well as a avid golfer.

 

 

The drainage swale project on hole 2 is complete and we will start on the final grading and seeding of the new red tee soon. The swale will allow rain water to enter the pond system faster without flooding holes 2 and 9.  

 

My next post will be on the greens aerification process. Hopefully we will have great weather to do this unpleasant job and the process and greens healing will be quick.

June grooming and projects

It's the first week of June and in some ways it feels like it should be April 15th and in others ways it feels like August. For the turfgrass you play on and the trees if feels like early May with July rapidly approaching. The course has matured a lot in the past ten days as ample rain, warm nights and days filled with sunshine have allowed growth to peak.

Monday, June 2nd we verticut or thatched the greens on all three 9's despite the 3" of rain before and after the job. Holes 1-14 were done and topdressed with sand before the heavy downpours and for golfers it is hard to tell we did anything because the huge rain drops pounded the sand into the turf. For holes 15-27 and the extra greens we were not as lucky and gofers will see some sand although it should not effect ball roll. The verticutting and sanding are key to providing smooth and consistent greens though the season. The cutting action from the verticut blades fills old ball marks and other small inconsistencies on the greens.

Last month I discussed the bridge collapse and am happy to say despite the wet weather we were able to get a culvert crossing in place to replace the bridge. In a ideal world we would have had time to engineer a new bridge but with that being the only way to get carts from hole 19 to 20 time was of the essence. Future plans are to add a second culvert crossing for hole 17 to replace the walking bridge over Ray's Creek.

Our work continues on the drainage project on hole 2. The damage from the haul road has been graded and seeded but every time we final grade the swale itself we are blessed with heavy rain before we can get it seeded. The project will help reduce flooding on hole 2 and 9.

The new family tees are installed on each hole and the brass plates are marked with a gold or blue flag so they are easy to see. I have seen a few groups using the tees and they will see more use when the junior programs start. The gold tees average 2065 yards per 9 and the blue 1520 yards.

We are lucky to have great staff members in both the clubhouse and maintenance departments and it is nice to see the students back to help us serve you.



Spring Fling!

Golfers and golf course staffs were spoiled by the early spring in 2012 and have been cursed by the late cold springs of 2013 and now again in 2014. Although we were able to open on April 5th the course has been cold and slow to green up.

Fortunately the recent increase in temperatures and helped dry the course and green up the playing surfaces. As I write this on May 6th the trees are just starting to bud out and the rough is just starting to grow. Some new things you may notice on the golf course include:

On hole two we changed the route for water draining from Trowbridge Drive into the pond by the tees. Last fall we dug a new ditch to allow the water to reach the pond via a culvert under the cart path. As part of the project mounding is being built left of the tee and right of the fairway bunker and a new forward tee will be added. Disappointingly they fall rains and early winter put a halt to the project so the areas will need to be graded and seeded this spring.

The rains stopped and the winds cooperated to allow us to mow about half our gorse or natural no-mow areas. Controlled burns reduce weeds and promote healthier growth of the grasses. Burning also returns nutrients to the soil while improving the overall visual quality of the no-mow areas.

 

Burning reduces last years matted vegetation.

 

The marsh grasses on hole 14 burn quickly.

In a bit of bad news part of the bridge used to go from holes 19 to 20 and 17 to 18 collapsed on May 5th. Due to the importance of the creek crossing we have to move fast to provide a passage way for the carts. We plan to install two 24" culverts side by side to the back right of 19 green for traffic going to hole 20 and a 36" culvert on hole 17 near the walking bridge.

Both of these crossings will be more convenient and a shorter route to the next hole. It may take a few weeks to bring in a air compressor and jack hammer to take out the old bridge and abutments so we appreciate your patience.

The right span of the bridge behind 19 green collapsed. It will be

replaced with a culvert crossing.

Fall Activities

Late fall is usually a good time for getting work done and playing golf but the wetter than normal and cooler than normal weather has put a little damper on that.  Since mid-October is seems as though if it isn’t raining it is windy. The weather usually averages out so perhaps the recent cool spell will be replaced with a few nice days to get the last rounds in.

We have a few things going on besides leaf cleanup on the course.

 

BLOWOUT – On October 30/31 we “blew out” the irrigation system. We rent a 750 CFM air compressor and set it up by the pumphouse. We then use the compressed air to “blow out” any water that could freeze in winter causing pipes to burst. We work in all directions away from the compressor to push the water to the ends of the course.

Although it rained both days it made the job quicker because we did not have to look out for golfers when turning on heads. Due to the size of our pipe system we blow out the system 3 times with time for water to settle to the low areas between each shift. This ensures a complete job and no problems next spring.

HOLE 2 DRAINAGE – You may have seen the dump truck and backhoe working over on the left side of hole 2. When we have medium and heavy rains the water that comes down swale on the left of hole 2 backs up onto hole 9 because our underground piping cannot handle all the water at once. We are extending the swale all the way to the pond so the drainage system will handle the water from the golf course and the new swale will handle the water coming from Trowbridge Drive and the Industrial Park.

The spoils or dirt from the new swale is being used to build a mound on the right side of hole two for a visual effect for holes 2 and 9. The mound is in the natural area and considered. The new portion of the swale will be out of play for most golfers and runs right along the out of bounds. It will not be marked as a water hazard but it may have casual water in it at times.

NATURAL GRASS AREAS – We hope to burn most of our natural areas this fall or next spring to reduce organic matter and mat that builds up from the leaf tissue. We have mowed the areas that are too close to buildings or the neighbors to burn but the others we will leave with hopes a low humidity weather window for burning will happen before spring growth.

Burning in fall usually provides a hotter more complete burn while spring burning is cooler because the ground is cool and wet.  With the industrial park and roads around the course we need the wind to be in different directions for burning different areas so it takes a few days to complete the job.

NEW TEES – Through the US Kids Golf Program Rolling Meadows is going to create a “PGA Family Course” with two additional sets of tees per hole. For a few years we had our “yellow tees” in the fairways. Those will be replaced with a blue and gold set to yardages recommended to allow juniors and beginners to use the same variety of clubs longer hitters use.

At this time most of the tees will be placed on the edge of fairways and marked with PGA Family Tee markers. The tees will not be limited to juniors or beginners as we expect some of our seniors to use them and hope other players will use them in the spirit of “Tee It Forward” to play a shorter course.

 

The graphic shows that if the average white tee player uses a driver/7iron to reach the green the Family Course Tee player will do the same.

We will mow greens, tees and fairways one more time to clean them up so we can spray winter fungicides on them. Greens will then be top-dressed with a heavy layer of sand to ensure a smooth surface for next year and to reduce thatch levels.

I hope to see you out on the links a few more times before the snow flies for good.

Didn't You Dig That Hole Last Year?

Thank you for noticing but last year we dug over there, two years ago and three years ago we dug here...... Irrigation leaks happen to all golf courses just like water main breaks happen to all communities no matter how large or small or how new the system may be.

Our golf course like most has several miles of piping underground leading from our pumpstation located behind the 11th green to the 500+ sprinkler heads. All of our underground piping is PVC and varies from 6" near the pumphouse to 2" around the greens and tees.

Our pumpstation has two 75 horsepower pumps for general pumping and a 5 horsepower pump for maintaining the pressure or running one or two heads. We keep the pressure in the pipes at 80psi when we are not watering to reduce stress on our pipes but the pressure slowly increases based on flow rates to 110psi when pumping over 200 gallons per minute up to the 1400 gallons per minute capacity of the station. We have seen our number of leaks decrease by over 50% by keeping the pressure lower when not watering.

Leaks can happen due to improper glue fittings, defective parts, stress from the ground moving due to freeze / thaw or dry / wet periods and water hammer. We blow out all the pipes with compressed air each fall so breaks from the pipes freezing are very rare.

This particular repair on hole 17 was made for the fourth time which is rare. We average 4 leaks a year and in my 16 years we repaired 2 of them twice and now this one 4 times.

This section of pipe is a 6" mainline with a 4" tee leading up hole 17. The first time we had a glue fitting leaking and found the entire area encased in concrete. We chiseled out the area to be repaired and being it was the middle of summer took the easy route and repaired only that section. The repair was difficult because the pipes did not line up close at all so we had to pry quite a bit to get it all together.

That lasted a couple weeks when the stress was too strong and the new glue fitting failed.We made the decision due to the pipes not lining up to dig up both sides of the pipe, rent a jackhammer and air compressor to break out the concrete and replace the entire area. We made what we thought was a good repair and it lasted a year when our new 6" tee cracked either through the ground moving, a defect or the pipes moving due to water hammer even though we had properly installed thrust blocks.

We made our repairs and this time used more gasket fittings rather than glue to allow the pipes a little flex and we thrust blocked them again to ensure we would not have problems. Well that lasted two years when the tee split again during the recent dry spell leading us to think the pipes are moving as the clay dries and re-wets.

Our irrigation consultant Tom Emmerich suggested we use a ductile iron tee and fittings to take the stress better than the PVC fittings. So $1,100 and a lot of digging later the repair was made and we are up and running again. I hope this is the last time we see this stretch of pipe.

Working in slop is never fun!

The PVC fittings have been replaced with a ductile iron tee and 

couplers to give it more strength. After this picture we added thrust blocks and

filled in the hole.

Summer Maintenance

It is hard to believe it is middle August and our hard working student employees are heading back to college. It seems as though they have just started. I had good intentions to keep this blog updated but one thing led to another and work on the golf course comes before updates!

After a wet and cold spring and early summer the weather the past 6 weeks has been darn near perfect for golf. Ample rain and cool nights have been kind gifts from Mother Nature. I wanted to highlight some of the maintenance activities we do to keep the putting greens consistent from week to week through the growing season. 'Growing" is a key word because unlike carpet the grass is always growing or changing and we need to manipulate it to preform as we want it to.

Even at 1/8" height of cut on greens new shoots are growing and old shoots are dying as well as stolons, rhizomes and roots. All this activity combined causes thatch to accumulate in the turf canopy. A little thatch is okay but on putting greens less is best in order to provide smooth firm surfaces that are receptive to a well hit golf ball.

Core aerifying may be the best way to reduce thatch levels but that is disruptive to putting so it is only done once or twice per year. The second best way is to verticut or thatch the greens by cutting the grass vertically by using blades that go 1/8" into the turf canopy. Verticutting is time consuming and messy but leaves the greens putting smooth.

This greensmower has special carbide tipped verticut blades to thatch the greens

 leaving quite a mess of debris.

After one mowing most of the debris is removed but some remains.

After blowing off the debris and mowing in two more directions the lines are visible

but the green is ready for play or topdressing with sand.

A light layer of sand also smooths the surface of the green while

diluting the thatch in the turf canopy.

After a topdressing with a sand that meets USGA specifications the green is

rolled and ready for play.

 Our other main activity on putting greens is to increase air exchange by opening up the turf canopy without reducing putting quality. The easier it is for air to move in and out of the greens the healthier they will be and the more they will survive the heat of summer.

 

This spiker attachment on our sand rake can make thin 1" long by 1.5" deep holes for air and water to move through. Although the holes are not deep we can spike all 28 greens in 4 hours.

Our Toro Procore 648 is fitted with 60 needle tines to leave a 1/8" wide x 3.5" deep hole. These holes provide for great air exchange but the process takes 11 hours for all 28 greens.

After mowing and a light topdressing with sand the holes are visible but

do not reduce putting quality.

All these processes along with proper watering, fertilization, fungicide treatments and help from mother nature provide consistent greens through the golf season.

Spring at last!

The weeks have been flying by and it seems the weather is finally cooperating for some great golf. I am a bit behind on my posts and it seems 6 weeks of work to prepare for late May golf was crunched into 3 weeks.

Thankfully college is out and most of our seasonal employees arrive this week to gleefully start mowing and maintaining the course. They are a valuable part of our team and allow you to enjoy great conditions day in and day out.

What happened to the trees????? This is the number one question I have heard this year as golfers returned to see some large trees had been removed over the winter. All of the trees large or small were losing branches during every wind storm and had become a danger to golfers. They were 40 year old silver maple or green ash trees that one were planted too close to the greens and two were at the end of their useful life. In addition the trees on 4 and 16 caused morning shade reducing putting green quality and the trees on hole 4, 16 and 27 had roots that went under the green and further reduced putting green quality.

• On hole 4 four silver maple and one ash were removed. New trees are not needed due to the tree line a little behind the green.
• One hole 16 three large silver maples were removed. Replacements will be planted to the center and right of the green only a bit further away.
• One hole 27 two silver maple were removed and will be replaced but further from the green.

You may have noticed we have resodded some of the collars around the greens where the grass was thin and reseeded fairways and collars for the same reason. 

New sod being laid on the collar on hole 5.

 

 

The sod came from Heath Farms near Coloma and is pure low mow bluegrass. It looks terrific and deep green. It should play well as soon as it is mowed a few times. The areas that were not sodded were aerified and then seed was was spread and spiked in. This process does not provide a instant green but will help those areas recover quicker. Most of the thin areas have some green in them but were damaged from water sitting in winter and were weak entering fall from last summers drought.

 

PROJECT UPDATES -

The 10 tee and chipping green seedlings are coming up albeit slow after the long winter and cold spring. The surrounds of the chipping green were all seeded but the green itself still needs a little more mix to be added before it is seeded sometime in the next two weeks. A few golfers have asked if we are putting top soil on the sand/peat moss material the green is made of now. No, the sand/peatmoss mix is the proper material to build a green that is healthy yet drains well for quality putting conditions.

 

The new red silver tee on hole 17 should also be seeded in the next two weeks. It has been graded a couple times and is ready for the irrigation and cart path to be installed. Then one final grading will have it ready for seed.

 

I hope to see you on the links and if you have any questions about the golf course do not hesitate to ask away! It is why I am here.
