Winter Update

It has certainly been an unusual winter for our region. It even felt more like May weather a few times this month. Hopefully this trend continues once we get into March.

I am happy with the state of our Bermuda fairways this year. I think everyone can see that our programs have been working and we have a much cleaner and consistent playing surface. While I know it is not ideal, I have to ask all golfers to please keep your carts off of the fairways while the Bermuda is still dormant, unless you are crossing the fairway. Cart traffic on dormant Bermuda grass can significantly impact spring green up and conditions. Traffic over the course of winter damages the plant and it does not have the ability to recover until it wakes up and is actively growing. When it is damaged, the plant must regrow from the crown which can delay green up by a couple weeks or even a month. This means that the conditions we all want out on the course will take longer to get here. So please help us by keeping your golf cart off the fairway.

I would also like to provide an update on the work we have been doing over the winter months. The majority of our crew is laid off for the winter months but there is still plenty of work to get done. We have been putting our new stump grinder to use. Over 200 stumps have been ground throughout the course. I would estimate that 95% of the stumps on the front 9 are no longer there. We still have a significant number of stumps left to grind on the back 9. We only have a few holes left to backfill on the front 9. The grinder can make quick work of the stumps but it still requires a lot of man hours to remove the debris and backfill the holes with soil. We have also removed a good number of dead and hazardous trees from the property, although, we still have others that we need to address. Refurbishing accessories is another job we get done this time of year because once the season begins we will not have time to work on them. Trashcans and ball washers have been sanded and repainted. New tee markers have been cut and painted from some beech tree limbs as well. We still need to do a light sanding on benches and apply a fresh coat of stain. Course cleanup is also a constant job on the course with the number of trees we have on our property. Once we get into March and some of our seasonal employees return we also plan on getting some of our troublesome bunkers back into form.

One last request that is always important but especially this time of year. Please repair your ballmark and at least one other when you are out playing the course.

Thank you and I look forward to seeing you out on the course!

Spring is almost here!

Golf Course Update

 

Looking at the extended forecast it looks like spring may be arriving a little bit earlier this year than last year. The next month will be a very busy one on the golf course. Our seasonal employees will be returning to work over the next few weeks to help us get the course ready for the start of the golf season. We are all anxious for the return of warmer weather and it felt good getting our first mowing of the greens done this week.

 

On Monday 3/7(Weather Dependent) we will be applying an herbicide to our front 9 fairways. This product will kill any poa annua contamination in the Bermuda grass fairways. Removing poa annua will provide a more consistent and clean playing surface. It will also help when the Bermuda grass is coming out of dormancy by removing its competition. We are only spraying 9 fairways in this application because this product must be able to dry before allowing any traffic on it. We will follow up with an application of the same product on our back 9 fairways on Monday 3/14 (Weather Dependent).

 

Another project that will soon be underway is the construction of a bridge across the dam on hole #9. Materials for the bridge are set for delivery on Wednesday 3/9. Once we have the necessary materials construction will begin. The construction process may take a few weeks. I thank everyone for their patience and I think we will all be happy once we no longer need to use the temporary detour that has been put in place.

 

Spring also means that it is time for aerification on our greens again. Our aerification is scheduled for Monday 3/14 and Tuesday 3/15. The plan is to aerify the back 9 on Monday and the front 9 on Tuesday. We will be using ½” coring tines. While aerification can be a dreaded process it is essential to provide the best playing conditions throughout the golf season. Once the cores are removed we will put down dry topdressing sand and work it into the aerification holes. The sand filled holes left behind will help maximize the bentgrass’s new root growth and prep it for the heat of summer.

 

Bunker repair will begin next week as well once we have some more manpower. To put the bunkers back together after some of the weather we have received over the last month will be a time consuming process.  We have also ordered 2 truckloads of bunker sand to continue adding/replacing sand in bunkers as is needed.

 

With the great temperatures forecasted for next week I hope to see you out on the golf course!

Winter is almost here

Weather has finally begun to cool off and things are starting to slow down on the golf course. The majority of the leaves have come down and we are continuing to work on keeping the course clean and playable. Fall has been warmer than usual which has kept the crew busy with more mowing than is typical for this time of year. The temperature changes over the past week appear to have finally slowed down the growth of the grass however.

 

 The Bermuda grass fairways have begun to go dormant and have lost a lot of their color as the seasons change and more frosts take their toll. Once the Bermuda grass is dormant I would like to see as little cart traffic as possible on it.  Excessive traffic on dormant Bermuda can cause winterkill and will lead to a much longer spring recovery. While playing and driving to your ball it would be helpful if you keep your carts in the rough and off of the fairways as much as possible. This will help out dramatically come spring.

 

On Monday 11/30 we will begin purging the water from our irrigation pipes. This is when we blow compressed air through our miles of irrigation pipe and blow it out of each of our irrigation heads to remove all the water. This is performed so that the irrigation lines do not freeze which could lead to pipe breaks or broken irrigation heads. If you notice irrigation heads being turned on, it is the water being pushed out of the system. This process should take 3-4 days and should not have any impact on golfers.

 

Once we have caught up with leaf cleanup, the size of our crew will decrease dramatically, but we still have plans for projects throughout the winter season. We will continue to repair bunkers, work on drainage projects, level areas adjacent to cart paths, perform tree work, and root pruning.

 

I hope everyone enjoys their Thanksgiving Holiday. It looks like beautiful weather on Thursday and Friday. Come out and take advantage of the warm weather while you still can.

Greens Aeration

On Monday, August 17 we will perform our late summer ¼” core aerification followed by light sand topdressing. The golf course will be closed all day for the aerification. We are also planning on aerifying the practice greens on Thursday/Friday of this week. Doing the practice greens this week will give us a head start and allow everyone to see how the aerification will affect the greens this weekend. The greens will receive a little bit of additional fertilizer this week and we will also lower the rate of our growth regulator. In doing so, the holes will fill in at a much faster rate, but the speeds may be a little slower. The ¼” cores we are removing are very small and should not have a major impact on playing conditions. I expect the greens to be healed up completely in 1 ½ to 2 weeks.

Aerification is a proactive and necessary maintenance procedure that keeps greens healthy and playable. The holes from aerification provide the roots more oxygen, in turn making the grass healthier and at the same time aiding in firming up the playing surface of the greens. The process is a temporary disruption for a long term benefit as we strive to provide the best possible playing conditions at all times.

Overall the greens have performed quite well this year. Over the last couple of weeks we have seen some areas begin to show some stress and the toll of lots of play and foot traffic. As a proactive measure we have started to walk mow the greens on holes 13-16 to remove some of the stress. We also relocated some of the fans used on the course to focus on areas that have been receiving heavier traffic. Visually I have already noticed a positive response to these changes.

We are also continuing to work on the bunkers. We ran out of bunker sand last week but received two new truckloads of bunker sand yesterday. A crew is working on adding/replacing sand on hole #8 today (8/11). This is a time consuming process, but we are committed to improving the condition of our bunkers on the course.

 

Remember to fix your ballmarks and divots! Thank you!

Hot, Wet Start to Summer

We have had an extremely hot and wet start to summer this year, but the course has held up quite well. As of this post we have experienced 19 days of 90+ temperatures since the start of May. Last summer we only had 12 days reach 90 degrees all summer long. According to DC area weather history we are off to one of the hottest starts to summer on record. To top it off, June has also been an extremely wet month. After another .7” of rain on the 26th, we have received 9.65” for the month(most on record in June since 1972) so far with another 1-2” expected in the last few days of the month. The average June rainfall is 3.8” for the entire month.

While rain can be good for our turfgrass it can also be harmful when we receive excessive amounts; especially when combined with extreme temperatures. Because of the prolonged wetness and heat combined with humidity, the grass has been very susceptible to disease. We monitor daily for turf diseases and spray products preventatively to protect the grass. Root loss is another major concern when dealing with these conditions. When the upper portion of the soil remains wet, the plant does not need to send roots deeper to find water. This will cause the grass to wilt more rapidly as the summer goes on. Fortunately our rooting is still looking very good to this point. We were able to perform a “venting” on our greens 2 weeks ago at a perfect time. Venting is the process of using small needle tines to create effect holes in the green which allow for air and water to exchange through the profile. One more negative impact of the recent weather pattern is the amount of ball marking that occurs due to the softness of the greens surface. This has become much more evident in the last week. Please be conscious of this when you are playing, and try to take a few extra seconds to fix your ball mark plus someone else’s when you are on a green.

While the heat may not be good for our Bentgrass surfaces, the Bermudagrass loves it. After a slow start, the Bermudagrass has finally started to fill in nicely on the fairways. Last week we sprayed them with Primo, a plant growth regulator to help tighten them up and provide more consistent playing conditions. The 9th fairway is still lagging behind the other fairways for several reasons. The primary reason is due to how poorly the fairway drains. This is one of the first areas we need to address when adding drainage this year. This fairway also suffered a lot more winterkill than the other fairways on the course. This week we laid Bermuda sod on weak areas of par 3 tees on holes 3, 8, and 11 as well as the driving range. These surfaces should be ready for play in three weeks.

Thank you and I look forward to seeing you out on the course!
