New Driving Range Tees


As promised, the updates will be a little more frequent than they have over the last year. The course has been playing great. The weather has been unusually dry and mild so has provided great conditions for fall golf. The yearly battle with the leaves seemed to take longer than normal but the high winds that ushered in the winter weather over the last few days have taken care of the remainder of them. The next job on the list is to get the fescues and brush cut before the snow arrives.


The big project this fall was the renovation of the driving range tees. The tees were built in 2004 and over the years the surface has raised 6-8" from divot repair and the topdressing needed to keep them smooth and level. Over the last two seasons the complaints on the tee conditions greatly increased which was not surprising considering their age. Although the life span can vary - based on my research - most clubs look at resurfacing every 5-6 years so the build up and poorer quality surface is not as noticeable.

There was more material than we first thought!


The secondary issue was the club has become significantly busier over the last few seasons resulting in a lot more wear on the driving range tees. The mild spring this year didn't help either, as the tee was being used before the turf woke up, so there was no healing; therefore they started the season in poor shape. The solution was to add mats that can be hit from over the winter and not damage the turf. Additionally the mats will be used for outings and on days that are not traditionally busy to help minimize the wear on the real turf. 











Among the complaints was that the driving range tees did not play like a fairway; which was something that is difficult to achieve as the range tees are sand based like a course teebox, whereas the fairways are grown on native soil. A sand based tee is beneficial as it drains well and in summer if it dries out it is not too difficult to push tees into. The turf on the range tees is bentgrass just like the tees and fairways on the course. For consistency it was used again to make them as close to course conditions as possible. Some other grass types that heal quicker were discussed but they would not play like the course.

The tees were covered to help speed up germination - the bentgrass seed has germinated and will provide a head start for the spring


The two little practice bunkers were filled in and a larger more usable one was built in front of the tees. The new bunker was designed to provide different shot angles over low and high faces. The area where the old bunkers were filled in was regraded with the native soil to provide an area to practice uneven lies which provides more realistic fairway shots. The lip of the new bunker was built using Ecobunker (marketed as Permaedge in the US). Old synthetic turf is used instead of real sod to create the lip. This helps minimize erosion and contamination of the sand, and when coupled with a liner like Blinder greatly increases the lifespan of the sand and therefore the bunker.

Finally an Update! The summer in review.


Finally! I have the time to get back to blogging and provide an update of what's been going on at LedgeRock over the last six months. I can't believe the last update was the spring aeration update in May. Fortunately that means that I have a lot to talk about and I can't use writers block as an excuse for not updating! Although the summer of 2016 is behind us I'm sure everyone will be interested in reading what was going on. 


When I wrote the last post the area was in a very wet period and I was wondering when it was going to stop. Just like every other time I wish for the weather to change, it did, and in true fashion it went to the other extreme! Most turf managers in the region will say that this summer was a tough one but thankfully a few perfectly timed rains meant that LedgeRock came through fine and with minimal issues. 

A dry summer can be great provided there is good quality water available and there is some tolerance for some brown dormant turf. Wet and humid conditions are less than ideal. The toughest stretch started in late July through mid August when the humidity rose along with the temperatures. In particular the night time temps stayed up which added a lot of stress and a huge increase in disease pressure. The disease pressure was such that it broke though a fungicide application and brown patch appeared on some fairways. It was interesting to see that it was on the more shaded fairways which showed that the increased moisture and humidity in these areas made it worse. Spraying another fungicide brought it under control but the damage was done. It didn't look too bad until the course was aerated. The disease was somewhat camouflaged under the leaves of the turf, so when the brushing from the aeration process stood the turf up, it showed the thin areas below. In all my years in the business I haven't seen that much brown patch.... The areas were seeded with divot mix and within a few weeks had started to heal up but it was certainly a first for me and showed how stressful this summer actually was. An unexpected rain storm the night before aeration left a few areas on fairways too wet so they were damaged from the aeration practices. These areas were seeded and were looking great by the time the aeration holes healed.

Anyone that has been following this blog for a few years knows how less than ideal growing environments effect turf conditions and what has been done at LedgeRock to rectify it. The work  done last year with the drain-lines and the addition of acid injection greatly helped with reducing the stress on the pocketed greens.

2016 built on the success of 2015 with the greens performing well all summer and coming through aeration without any major issues. 10 green still struggled a little after aeration and was thin for a period afterwards. It was somewhat expected! I wanted to see if the green could survive with the shade from the Bald Cypress tree to the left. Unfortunately this year showed that it has to go as the thin turf area on the green followed the same pattern as the summer morning shade from the tree. Considering how the others are performing now, I am confident that 10 will follow them next year when the last major issue (ie the tree) is corrected. The factors limiting growth have been greatly reduced so these greens now play all summer like the others but they still need attention to make sure they keep progressing as they are and make sure that they stay healthy.

One item that needs adjusting going forward is the topdressing program. Due to the schedule over the last few years, topdressing frequency has taken a step back and it hasn't been performed as much as I'd like. The soil physical tests are coming back positive but it is important to ensure that it is taken care of before it becomes an issue. The golf shop and the maintenance dept plan to work on a schedule for 2017 that benefits both golf and maintenance and minimizes the effect on play-ability of the course

The fresh topdressing can be seen on top, the aeration and dryject holes can be seen and slight mottled look near the surface which will necessitate more frequent topdressing to ensure it does not become a problem. The line in each picture shows the interface between the original mix and the layer what has been built up with topdressing and keeping the organic content at a minimum.



The only major criticism received about the course this year was that it was wet after aeration. I understand that it was far from ideal playing conditions for the couple of weeks or so after aeration. There was a twofold reason for this. The lessor one is that the new seed mentioned above needed water during what turned out to be an extended spell without major precipitation. The second was to help heal the course as quickly as possible after aeration. Unfortunately the course needs aeration which effects play and it needs water to get it to heal as quickly as possible. While the softer conditions are less than ideal they are a small price to pay to have a successful aeration minimizing turf stress so golf can be played for the remainder of the season without any issues.


The addition of the acid injection system proved to be a major asset this year, to the point where at a few times this summer I felt that the course was too green! The acid injection helps improve the water quality which has been an issue for the last few years. It was installed last year but it was mid season until it was fully up and running and it took some time to get it dialed in. This year it proved it's worth by not only giving the turf a better quality water source but it also makes pesticides work better which in turn reduces the amount of them needed. The better quality water also reduced the amount of fertility needed on the course as, although there is a minimal amount of nitrogen in the product, the better quality water releases tied up nutrients that were previously locked up in the soil.

The course was healthy and played firm and fast all summer

The tree work and regrading around 4 green greatly improved the playability and the look of the hole by opening up the right side of the green. With the trees gone, irrigation was added along the edge of the cart path which meant this area could finally be maintained as it should. There was a small area near the approach where the sod died due to poor irrigation coverage but that has been corrected and the area resodded.

Lastly, it's that time of the year where there will be frost delays; this post  is a reminder of why they are necessary to protect the turf from damage.
