Approach Topdressing

During our annual August fairway aerification, we treat the approaches differently than the rest of the fairway.  On most of the fairway acreage, the aerification plugs are chopped  and dragged to separate the soil from the thatch.  The thatch is then collected and removed, while the soil is dragged back into the holes.

However, on the approaches, the whole aerification plug is picked up and removed.  The approach is then topdressed with sand, which is broomed into the holes.  The long-term goal of this process is to help in firming up the approaches.

Sand is being applied to #2 approach.

The Transformer

This past winter we replaced our 1990 backhoe with a smaller, more versatile machine.  Throughout most of the year it functions as a front-end loader and backhoe.  However, during aerification time, when we need every piece of equipment available for clean-up duty, the new Kubota quickly transforms to a standard utility tractor.

Aerification Update

We had two days this week scheduled for aerification, and given this year's weather, it should have come as no surprise that it rained on both of those days.

Monday morning we started aerifying greens, and by mid-day things were rolling along smoothly--until the skies opened up around 1:00, for about 15 minutes.  At that time, we had greens in every different phase of the operation.  What does that mean?

Here are the steps we take during the August aerification:

• Greens are aerified.
• Plugs are blown in around the edges.
• Plugs are removed and any clumps are blown from putting surface.
• Sand is applied.
• Sand is broomed into the holes.
• Green is a given a final blowing.

So, at the time it started raining, a few greens had all of these steps completed, while most were in some different stage, and others weren't even aerified yet.  The result was something of a mess.  Wet plugs aren't the easiest thing to cleanly remove, and as it got later in the day, some of the plugs that had been rained on began to dry and stick to the green's surface--this was not  a lot of fun. 

The rain also played havoc on getting the right amount of sand applied.  Some sand was nicely washed into the holes, other sand moved across the green from the rain, and in other areas it "bridged" on top of the holes.  It felt like Goldilocks again, with some greens looking like there was too much sand, others too little, and some just right.

On Tuesday we were ready to move on to tees...but Mother Nature had other plans in store for the morning.  After making a go of it on a handful of tees in the morning, thunder and lightning chased us off the course.  By the time the rain stopped it was too wet to even attempt pulling cores.

We ended the week with great weather and got started on a couple of fairways.  If nothing else, the rain earlier in the week ushered in some cool nights which should help the greens heal quickly.


Three days after aerification, the greens are starting to fill in.

Fescue Trial

As you play #8, you'll see a section of Fescue that's been mown closely and is now roped off.  For those who often find themselves spending time looking for a ball in this area, the bad news is that this won't stay short forever.  So, what's going on?

Excess organic matter is raked up and removed from #8.
 

This location is being used as a trial area for a different variety of Fescue.  In a few weeks, this small patch of Fescue is going to be reseeded using a variety of Hard Fescue known as  Aurora Gold.  Prior to seeding, we will make multiple applications of Roundup to make sure we are starting with a weed free area.

The goal is to establish Fescue that meets the goals of being penal, while still allowing a ball to be found and advanced.


A dye is added to the Roundup so we can see that there is thorough coverage.
 



Tee Irrigation Update

If you've been on the course lately, you probably saw lots of activity around the tees.  Our irrigation contractor is doing a great job of quickly and efficiently installing the new sprinklers and piping.

Unlike the older sprinklers which were spaced 80' apart, the new layout is using spacing from 30'-45' so we may more accurately place the water where needed.  We are also using HDPE piping instead of PVC.  With HDPE, sections of pipe and fittings are fused together, creating a monolithic system, which virtually eliminates the chance of leaks.

We apologize for any inconvenience, and will try to minimize the impact to players by relocating the tee markers on the hole the contractor is working on.

With a large crew, the tee irrigation project is moving along quickly.

Practice Tee Plan

While droughts aren't great for golf course conditions, they at least allow us to control the water which is supplied to the turf--and that definitely hasn't been the case this summer.  The upper practice tee, which was much improved in 2012, and came into this spring as healthy as ever, has suffered due to the heat and unprecedented rainfall. 

Over the last couple of months, we have spent an extraordinary amount of time and effort in deep tine aerifying, seeding, and spraying this area...with poor results.  With plenty of heat, almost twelve inches of rain in June, and over nine inches so far in July, it appears that rice would have had a better chance of successful establishment than our cool season turf.

So, what's the answer?  Well, it would be easy to say that this summer's weather is just an anomaly, the upper tee was good in 2012, and we don't make any changes going forward.  However, it feels like record weather events are more the rule than the exception, so it seems prudent to plan for the worst, and hope for the best growing conditions.  Looking at the lower tee, it would appear that the answer to the upper tee's woes is right in front of us:  Bermudagrass.  Yes, the upper tee receives more care than almost any other area of the golf course, and is struggling, while the lower tee requires less attention than any area, and looks outstanding.

With that in mind, we have experimented with establishing some of the lower tee's Patriot Bermudagrass on the upper tee by spreading pieces of divots collected from the lower tee across a bare area of the upper tee.  As you can see in the photo, the Bermudagrass is thriving on the upper tee.  Earlier this week we aerified a portion of the lower tee and spread the plugs across the upper tee.  While this might not be the fastest way of introducing Bermudagrass to the upper tee, it will be interesting to see how much Bermuda takes hold in the next couple of months.

Because the Bermudagrass is only growing aggressively about five months of the year in our climate, once established on the upper tee, it will be overseeded to allow use of the upper tee during the spring and fall.  By next summer, the upper tee will be ready for the heat.

The lower tee's  Bermudagrass is thriving.

Tired Turf and Holes

The recent weather has been really tough on the turf.  Too much water in June, followed by extreme heat (and high nighttime temperatures) leave the grass feeling stressed.  Add some insects and lots of disease pressure, and it's like Rocky trying to take punch after punch from Apollo Creed.

Not surprisingly, the tougher the growing environment, the tougher it is on the turf.  Due to the growth of vegetation over the years, the right half of #18 green is "pocketed."  There is little air movement, and no morning sunlight. 

Patches of stressed turf aren't usually something to be proud of.  However, this is more about what is healthy than what is not. When people ask why we have to aerify, hopefully this picture tells the hole...uh, whole story.
