Golf Course Renovation Week 3

Week number three of the golf course renovation was all about the grass.  The fairways, which were seeded last week, have germinated and are growing very well.  On sunny, windy days they require a moderate amount of attention, but not nearly the amount of attention as a sand based green.  All greens were seeded this week, including #1 Green as its reconstruction was completed on Wednesday.  A total of 3200 pounds of bentgrass seed has been planted on schedule.  Although it may seem early, it is likely that staff will begin mowing by the end of next week.

Golf Course Renovation Week 2

The golf course has taken on a different look this week with the appearance of dead fairways and greens. The construction of #1 Green is nearing completion.  On Monday, Chris Cochran with Nicklaus Design was on site to rework and approve the sub-grade, which gave our construction contractor the remainder of the week to install drainage, gravel and sand mix.  Chris will return on Monday for final inspection and approval of #1 Green, and we anticipate seeding to occur on schedule next week.  

Fairway seeding was completed on Wednesday, and we will expect to see germination some time in the next couple of days.  The warmth, rain, and humid conditions will expedite germination.  However, these conditions have warranted precautionary and preventative treatments for the fungal pathogen Pythium, which thrives in conditions like this and can quickly destroy young, succulent plants.

Golf Course Renovation Week 1

The first week of closure to play has been very productive.  Our primary objective as we begin working on the golf course is to plant seed in the fairways and on the greens because the opening date next year will depend on the maturity of these two surfaces.  With some great weather, we have been able to keep a tight schedule, and to date there have been 4 acres of green prepped and sterilized, 36 acres of fairway/step-cut sprayed with roundup, and all approved tree removals around greens have been completed.  Our construction contractor is on schedule with the reconstruction of #1 green, and Nicklaus Design will be on site tomorrow to approve sub-grade.  We expect #1 green to be ready for seed on August 25 along with the rest of the greens.

Approach Drainage #9

Prior to re-grassing fairways and approaches this fall, staff is utilizing a closed Monday to install drainage throughout problematic areas in #9 approach.  Typically, we aim to install about 500 linear feet of perforated drain tile in problematic areas, and each year we have seen incremental improvements in their drainage as well as a significant reduction in winter kill from ice damage.

Normally, projects that are "in play" are handled in the shoulder seasons when the golf season is not in full swing.  We have elected to perform projects scheduled for late fall throughout the next two weeks due to the fairway renovation that will begin on August 11.  This will allow staff to focus on growth of the new turf without disturbing it and complete the projects that have been scheduled this calendar year.  It will also result in firmer playing conditions in the approach.

Trial Putting Green Update

As part of our bentgrass variety trial on the Putting Green, root mass samples are being taken on a monthly basis.  The depth of the root mass is important to us for a variety of reasons.  Some of the more obvious reasons for desiring a deep root mass relate to playing condition.  Less watering will equals firmer greens, less ball marks, and truer surfaces after being mowed or rolled.

From an agronomic standpoint, the benefits of a deep root mass are far reaching, especially with poor irrigation water quality.  Effluent water is the culprit of a plethora of issues associated with intensely maintained turf.  Excessive algae growth is common on greens, causing turf to thin and leaving voids for Poa annua to invade.  Black Layer, is also a very common cause of turf decline on sand based surfaces that are irrigated with effluent water.  It is caused by a colonization of sulphur reducing bacteria which release toxic gasses and create anaerobic (lack of oxygen) conditions in the soil.  Shade exacerbates each of these issues.

We have estimated that our water usage on the Putting Green has reduced by 85% since being re-grassed to bentgrass, and, due to this substantial reduction, black layer and algae blooms have been eliminated as issues to this point.  This has been made possible by the deep and dense root system of the bentgrass, and the growth of that root system was made possible by proper aeration and proper amounts of sunlight/air movement.

There are a couple of varieties on the Putting Green which have separated themselves from the pack with respect to rooting, which will weigh heavily in our decision making process for the grass type(s) chosen for the greens renovation this fall.  Seeing these thing on the ground and not only on sell sheets provided by seed manufactures is both exciting and impressive.

Golf Course Update

The staff has made some nice progress the past couple of weeks in repairing damaged areas of the golf course.  The "cover shuffle" has been a major part of our days, and some warm weather when tarps are not required will be a nice break for the guys.  

The above pictures of #17 green were taken on April 15 and May 7 respectively. Notice the striking contrast just twenty-two days later.  There is still quite a bit of filling in to do, but the seed on the greens has germinated and is growing.  Some warmer temps will help tremendously.  It will also help when the sun decides to make an appearance.

Here, you can see a close-up of what the surface looks like.  This surface has a long way to go prior to being open with quality conditions, but we are very proud of the progress we have made as team to get this stand of turf up in two weeks with very cold temperatures!

Fairway overseeding was completed last week in the several shaded areas where Poa annua persists.  These areas are not being covered and will begin to recover with some warmer weather.  Contaminated areas in the step cut that suffered from winter damage continue to be sodded.  

Finally, we expect the putting green will be ready to open by the end of next week.  Rooting this spring has breached 8" in several plots, which is everything we could ask for from a new stand of turf.

Golf Course Winter Update

We are beginning to see the majority of turf on the golf course for the first time in four months.  One of the concerns we have as turf managers in our region is how well the golf course will handle the winter weather when it is a brutal as this one has been.  Because we treat playing surfaces with plant protectants for snow mold our risk of major damage is minimal, and the amount of persistant snow cover has mitigated much of any wind burn.  However, it is evident that ice has made an impact on Poa annua playing surfaces this winter. Because the turf on our tees and fairways is predominantly bentgrass, there will be only minimal damage to repair.  We are confident that any damage to Poa annua in fairways is repairable without creating much of an impact to play.

Because the greens are predominantly Poa annua, which is much more susceptible to ice damage, there appears to be a considerable amount of damage to about 50% of them.  We will know more as the weather warms up and the covers come off, but samples that were taken from questionable areas are not showing signs of life after two weeks in the window.

Large areas on the front of #7 green and up the middle of number six green that hold water appear to be dead.  The plugs in the picture above have been transplanted and watered in dishes in a window sill in the grounds maintenance facility.

On number two green samples were taken from the front, which was covered in ice, and the back, which was not.  It is evident that the turf under the ice is not in good shape despite the fact that the ice was removed.

The trial putting green, although immature, appears to have made it through the winter in excellent shape as would be expected with bentgrass.
