Fall Progress Report

If you've played lately, you've probably noticed all of the mess around the course. The tees and approaches are getting shaggy, the collars are a little tall, and the fairways do not look as groomed as normal. The main reason for this lack of cleanliness is the recent sand topdressing.

The greens were aerified on September 15th and 16th and are now two weeks healed. The time between aerification and the first mowing varies from course to course depending on personal preference and the rate of growth and recovery. Personally, I do not like the turf to get too much taller than our regular playing height. If it does, we will have to adjust the mowers down between mowings to avoid injuring the plants. This time around, the greens were growing so fast that we cut them three days after punching holes. From then on we mowed everyday to keep up with growth. So what does this have to do with sand?

The topdressing absolutely destroys the blades of a mower. Each of the green mowers has a reel with 11 blades and a bedknife that completes the scissors action as the reel spins around. Each bedknife costs around $25 and must be replaced after mowing sand for a week. The reels can be sharpened and four mowers will take a full day to get back into shape. Obviously, we do not want to repeat this process more than once for each aerification. We closely monitor the amount of sand that each mower collects and decide when it is safe to put on some fresh blades. The difference is like night to day as a sharp edge will get more turf with a clean cut and leave a very crisp surface for your putting enjoyment.

The same is true with the fairway units, the tee mower, and the walk mowers used on the collars. We have to wait for the sand to settle down before we can start cutting with sharp reels.

Currently, the green mowers are sharpened, the fairway unit should be ready for tomorrow, and the tee mower is scheduled for Friday. Fall aerification and overseeding are always messy, so hopefully this helps to explain some of the time involved.

Fairway Topdressing

On Wednesday, September 23rd, we topdressed all of the fairways with 400 tons of sand. That sounds like a lot, but it is less than 1/8 of an inch. Over time, multiple topdressings will add up to make a difference and improve the soil and playing surface. I've scheduled two of these applications for next year, one in June and one in September.

We shot a little video of the topdressing process in all of its glory. We contract Reece Spray Service to do the job with this giant green truck. This is one of the heaviest vehicles I've ever put on a fairway, but the large tires spread out the weight and keep turf damage to a minimum. Assistant Superintendent, Mike Nee is shooting the video and trying his best to keep his little finger out of the shot. I'm commentating from inside the rig as we roll down down fairway.

The whole process took five hours to complete compared to 2 weeks for the in house application.

Aerification Update

Since my last post, the staff has put over 1 million holes in the playing surface. I wasn't counting, but who's going to argue after we've aerified all the fairways, tees, and collars. Today we will focus on punching the approaches and then move on to some high traffic areas near the greens.

Another project for today is the slit-seeding of the tees. We will walk slit-seed in two directions and follow with more seed, sand, and fertilizer. This tends to be a little messy as the tees will be de-thatched during the seeding effectively accomplishing two jobs at once. This is the most extensive seeding of the tees we've attempted and I expect wonderful results.

Tomorrow, Wednesday the 23rd, we will apply over 10 tons of sand per acre on the fairways. This is the most sand we've topdressed with and will work to improve drainage, decrease worms castings, and improve fairway firmness. These positive results can take years to develop as fairway topdressing is a slow process. Even at 10 tons per acre, we are applying less than an 1/8 inch of sand. Little by little, the composition of the soil will change by a small amount. Increasing the percentage of sand, even by a small fraction, can lead to a better playing surface.

The greens have all received their first mowing since being aerified only a few days ago. The back nine was a day ahead of the front and we mowed on Saturday, after only three days of healing. We should be completely healed well before the weekend as we start to get the course back to optimum playing conditions.

As always, thank you for your patience during these messy periods that are so vital to the health of the turf. I've received nothing but compliments and understanding from the membership and the staff and I definitely notice and appreciate the support.

Happy golfing.
