The journey to Tifeagle.

I thought I would give some background to the decision to change the West greens from Bentgrass to Tifeagle, so settle in for a read!!

CTHGC has had Bentgrass greens since the 1970’s and they have regularly provided a substandard putting surface during summer over the years often resulting in temporary greens being in play.  Bentgrass is classified as a “cool season grass” and will struggle in the sub-tropical climate that exists at CTHGC and that fact, coupled with the amount of play the courses receive, makes maintaining Bentgrass a difficult option.

March 6, 1980 was the first time that it was documented that a change to the greens was recommended to the Board from the Match and Greens Committee and there have been several more discussions, recommendations and consultant reports over the ensuing years.

It has always been an emotive topic and has resulted in much robust discussion at Board level and amongst the membership.  In 1998 the Board of the day passed a motion to change the back 9 greens on the River course to the Couchgrass variety Tifgreen 328 and the program was put in place.  All the greens were done at once to a design by course architect Peter Williams and the project commenced in October 1998 with plans put in place for the front 9 greens to be done the following year.  The back 9 greens were constructed and strictly followed the USGA specifications for greens construction and were solid turfed.

I arrived at the Club in June 1999 to greens on the back 9 River that had very high thatch levels but generally in good condition.  Budget limitations dictated that only three greens – 1, 2 & 6 – would be re-constructed in 1999.  On my advice all the front nine greens were re-turfed with Tifgreen 328 with 1, 2 & 6 being totally re-constructed.  The other six greens simply had the existing Bentgrass surface stripped off and turf laid which is why there is considerable encroachment by common Couch in some of these greens.

The West greens were also to be converted in the grand plan but once again budgetary limitations intervened and the fact that I was able to keep the greens in reasonable health during summer, the West conversion was shelved.  In 2005 17 West green was re- grassed using a recently developed strain of Bentgrass known as “Penn G2” which had been successfully trialed in our turf nursery adjacent to 17 River but the grass struggled to maintain a satisfactory year round putting surface on 17 West.  This was put down to the location of the green and wear from golfers as the grass thrived on the nursery.  A back up plan was devised of replacing the green with Couchgrass should it completely fail again.

In 2007 the Board of the day approved the Club’s participation in a Queensland Department of Primary Industries trial of the new “ultradwarf” Couchgrasses that had become available.  The Board also approved the construction of a nursery green for the trials and it was built with the same growing medium as would be used in future greens constructions.  We trialed six of the new improved “ultradwarf” varieties of Couchgrass with a view to their suitability as a putting green grass at CTHGC.  All of the varieties, proved to have a much finer leaf than “328” Couchgrass (which we have on the River greens) and therefore provided a better putting surface.  The variety Tifeagle was part of that trial and had been available in Australia previously with Northlakes GC planting the grass on their greens in the early 2000’s. Tifeagle was the stand out grass in our trials and provided an excellent putting surface with little susceptibility to disease outbreak.  It was therefore earmarked as the grass that would be used on 17 West.  

Some of the other issues faced by Bentgrass greens at CTHGC include;

Our climate.  The summers experienced at CTHGC are too severe to make bentgrass a viable option without huge labour and plant protectant product usage.  It is fact that bentgrass roots start stressing and dying off in soil temperatures above 24ºC.  In the months of November through March our soil temperatures rarely fall below 23ºC and the irrigation water that is applied is normally a minimum of 26ºC with a high sodium content.  I have in fact recorded soil temperatures above 35ºC on many occasions and the water has been 30ºC on many occasions.  The combination of these factors is a recipe for disaster.
The age of the greens. Some of the existing West greens are more than 30 years old, albeit with constant patching and re-sowing prior to my arrival.  Several of the greens, eg. 2, 3, 4, 10, 13 &15 have passed their use by date and are causing problems year round.
Foreign grass invasion. Particularly Couchgrass which has been controlled as far as possible with the available products.  All I am able to do now is reduce the spread of the Couchgrass.  Greens 4, 6, 8,10,12,14,15 and 18 are the worst for contamination.  This problem is most noticeable during the summer months when the Bent is at its weakest and the invading Couch at its strongest.  The most difficult aspect of controlling the existing Couchgrass is that to totally remove it from the surface it can only be sprayed out and then have at least 300mm of the growing medium removed and replaced.  In the past fumigation could be used which provided a fast result and meant the surface could be re-seeded as was done on many occasions previously.  Fumigation is now no longer available.
Staffing.  The maintenance of Bentgrass greens in this climate, particularly through the period of October thru April, requires a huge commitment from the Superintendent to continually monitor the greens.  One of the aspects that amazed me when I arrived here is just how much the greens can dry out overnight in comparison to greens in the southern States.  Similarly the change in the greens from 2.30pm in the afternoon when staff leaves and 6.30pm when the sun stops beating down is substantial.  This means the greens need to be monitored continually throughout the day, seven days a week and decisions on irrigation requirements assessed on a daily basis.  This didn’t happen prior to my arrival with obvious results.  Having Bentgrass greens in this climate is like having a 2 week old baby that is in need of constant attention. Such constant attention requires a commitment from the staff and the generation of workers coming through is not interested in working such hours and that trend seems to be getting worse.  The days of people working 70 plus hours a week as I do are numbered.

Unfortunately the backup plan for 17 West needed to be implemented in January 2015 when the green all but died from the combined stresses of disease and insect attack and Tifeagle was duly planted.  The other West greens were not far behind 17 in what was one of the most brutal summer’s I have experienced up here.  The biggest test for Tifeagle on 17 West was not how it would grow in summer but more so how it would survive the low growth time of winter which it has done exceptionally well over the past two winters. 

So the moment is nearly upon us with the conversion of the remaining back 9 West greens commencing on Tuesday October 4.  There will be weekly updates on this Blog for the information of members.

And just a photo to finish off this week with a shot of the nursery green in 2009 with 328 on the left and Tifeagle on the right.  The photo shows the disease pressure (small yellow discolored spots) on the two grasses with the bottom section of the photo having had plant protectant products applied and the top having nothing applied.  The Tifeagle on the right is almost disease free as it has been on 17 West.

Tifeagle on the right nearly disease free!!

The front nine West greens are back down to normal mowing height although there is still a fair amount of recovery required to get the surface back to normal.  The back 9 greens on the West are putting very well although they only have a few weeks left in their current dimensions!!  The temporaries had another sanding this week and are nearly at the height of the other West greens and should provide a very good putting surface.  They will be a little on the soft side due to the level of thatch that they were sown in to so pitch mark repair is still required.

I have been asked several times lately about what will happen with the material that is removed from the greens.  Apart from the grass most of the material is extremely useful although I don't expect good quality material to come out of 10W in particular.  Some of the grass will be trucked away whilst any suitable material will be carted a short distance and spread over tree root areas in among tree lines to help solve another problem we have.  Some material will be used as fill for some of the soft soggy areas at the front of greens such as 13 and 16.  Some of the material should be free of roots and other contaminants and it is planned to use this to topdress fairways and some tees if it is deemed good enough and there will also be some set aside for access repairs.  Considering that somewhere between 15 and 20 truckloads of fill material will be placed in each green there will certainly be some repair works necessary.  So hopefully very little will go to waste.

The weather continues and I don't think I have seen the tees in such good condition at this time of year before which is quite handy due to the play they are getting.  The back men's tees on the River had last weeks Medal followed by today's back marker challenge and now have four days of play in a week for the Club Champs.  Couple this with the disappointing number of players who persist playing from the back tees and it's a wonder there is any grass at all.  

Next week will see the removal of the tree stumps dotted around the courses and some preparatory work for the irrigation on the back 9 West greens.

 Good luck to all competitors in the Club Championships.

This week has all been about the renovations on the West course and although we only had to do 9 greens it seemed we were getting nowhere on Monday night.  A couple of staff are on annual leave which normally wouldn't happen for such a busy time but with only 9 greens being done I thought it would be manageable.  That was until a virtual sea greeted us on Monday morning with a major pipe failure between 13 and 14 West fairways just next to one that occurred in March this year.  The water level in the irrigation dam was low and with no way of getting to the repair on Monday due to the sheer volume of water I actually contemplated not doing the renovation as Bentgrass greens under renovation in this climate need water.  But we pressed ahead and the repair was finally finished late on Tuesday and the renovations were also completed.  I'm certainly glad we didn't have to try and do 18 though!!

New hazard on 13W!

The West course tees were also aerated with the cores rubbed back in to the surface which acts as both a fertiliser application and a top dressing.  The West fairways were aerated with a rather agricultural type of unit but nonetheless effective and mown back down with a local rule in place regarding relief from the aeration holes.

A nice 6mm of rain on Thursday night was just what the courses needed but there is a bit more predicted overnight and early tomorrow morning which is not what we want.  I also didn't want the Cockies to start tearing in to 5W green as they did late today.  Time for the decoy Eagle to come out once again which I hope will work.

90 tonne of sand was added to selected River course bunkers this week as advised on the Blog last week.  Most of the bunkers selected nearly had the drainage gravel layer showing which means they were 300mm deeper than originally constructed so not only are they now a little shallower but also more playable.

We did some root pruning along side some fairways last week with a machine that has been used here before to give the grass some chance to take up the nutrients and water rather than the trees.  Time will tell on its success.

All the irrigation components for the West greens have now arrived and it can finally be said that "next month" the project starts.  As part of the construction all existing irrigation will be removed and replaced by new equipment.  Some of the sprinklers in the greens date back to the 70's and are well past their use by date.  I have a consulting agronomist advising on the sand and the various amendments that are being included in the top growing soil profile and we went down to get some samples from the sand stockpiles that have been reserved for us to ensure they are suitable.  Once the existing greens are excavated out a sand that conforms with the USGA specification will be added with the top 100mm of USGA sand amended with various fertilisers.

80mm of rain on Wednesday wasn't really the preparation I was looking for with the Pro Am just 2 days away but the course took it well and the ground staff did a tremendous job again to get the course playable.  The 7 o'clock shotgun in the morning was a challenge but the staff stood tall and once again produced the goods.

A bit of tree trimming and removal of a couple of dangerous trees this week down the LHS of 3R opens the play lines up to make the hole much fairer.  The right side is earmarked for similar work in a few weeks.

The pipe for the new irrigation installation on the new West greens arrived this week which is another indicator of just how close the project is.  The temporary greens continue to develop and are almost growing too fast.

 Irrigation pipe.

Some sand will be added to bunkers next Monday and Tuesday which will replace some of the sand that has been played and blown out.  The bunker sand is trucked down from Caboolture and is widely used throughout SE Qld at the moment.  It is a blend of actual rated bunker sand and brickies loam which gives it some weight and water holding capacity and helps hold it in place.  We have been using this blend for some 8 years now.

And just for a laugh this was the actual grouping at last weeks tour in the USA.  Someone at least has a sense of humour!!

Have to laugh!!

I spent the first part of the past week at a conference in Tasmania that was held at Barnbougle and although the sun was out it was exceptionally cold although one of my playing partners in the golf was wearing shorts!! 

The daunting tee shot at Lost Farm #5

One of the presentations about communication with members had this as a final slide highlighting some of the tasks required of a modern day golf course superintendent which I thought showed the diverse range of tasks required;  

Environmental audits

Environmental reports

Environmental sustainability

Environmental compliance

Human resource plans

Human resource strategies

Human resource policies

Performance goals

Performance appraisals

Master plans

Capital works and budgets

OHS policies

Position descriptions even for apprentices

Strategic plans

Living documents

Staff induction

Professional development







When do we ever get time to smell the grass??

The temporary greens continue to develop and should provide an excellent alternative putting surface during the West course greens works.  Planning still continues with one of the next tasks to undertake some soil testing of the sand that has been stockpiled for the project.  Nearly 600 tonne of sand will be required for each green which even just transporting it in creates a logistical minefield.

Another great week of weather for the Veterans week of Golf with just a couple of spots of rain spoiling the perfect run late on Thursday.  It always amazes me the way the course is left after such huge player numbers and it's a credit to all the volunteers who come in and assist the organising committee. 
The temporary greens on the back 9 west received their first mowing today and look very good.  Unfortunately the ducks think they are looking good too and are grazing them daily.  Preparation for the greens works started back in April when the Board approved the works when the planning logistics of such a program started.  Labour, machinery contractors, staff, sand, fertilisers, irrigation and drainage materials as well as the grass itself are just some of the items requiring planning.  It is a big project to undertake and the bulk of the works will be done "inhouse". 

10W first mow.

The information below gives an outline of the proposed works;

  • Spray out as much foreign couchgrass as possible prior to excavation.

  • Excavate to a minimum depth of 400mm and a maximum of 600mm where couchgrass is present.  The greens will all be enlarged and 12 green will have minor surface adjustment to allow for fairer pin locations.  The surplus material will be either stockpiled for future use or spread in areas of tree roots in amongst trees close to the green being worked.  A select number of bunkers will be reduced in size.
  • Find greens drainage and ascertain condition and functionality.  Replace / upgrade / flush as necessary.
  • Green surrounds to be modified where required to improve water movement away from the green surface and surround.
  • Remove and replace all existing irrigation, some of which is 30+ years old.
  • Refill the green “well” with USGA specification sand, with the top 100mm being amended with various soil amendments.
  • Greens to be stolonised with Tifeagle.
