Course Update 9/27/18

Another 2" of rain fell since the last post one week ago, bringing our total rainfall to 11.02" for the month.  It seems like we can't catch a break, with more storms moving up from the south that will likely add to our total this evening.  Maybe we'll get lucky and the storms will miss us!

Either way, the golf courses are the wettest I've seen them in my 3 years here, and frankly I don't think they could get much worse.  Just walking off the cart path results in muddy shoes and splashing water.  You also need to be cautious while walking on uneven ground.  We've received a couple slip and fall reports due to the wet conditions, but thankfully no serious injuries.  Should you decide to take the cart off the path there's a very good chance you'll get stuck, and probably end up damaging the turf and leaving ruts that will be evident the rest of this year.  Managing a golf course given our present conditions is very challenging, and managing expectations is by far the most difficult job.  Greens are soft and nowhere close to the condition they should be in, and the same can be said for fairways, tees, and rough.  Greens were mowed Monday, and again today, although a couple had to be walk-mowed because we didn't want to damage the turf by using the normal riding mowers.  Our smaller, more maneuverable rough mowers have been out trying to find areas they can mow without causing long-term damage.  Fairways and tees also haven't been mowed since Monday, and we may not be able to mow them this week with additional rainfall.  Deciding whether to mow or not are made with the best interest of the membership in mind, and what will have the least impact on the courses long-term.

Since the greens are softer than normal, ball marks are much more evident.  It's been a while since we discussed it, so click the link below to watch a short video on how to properly repair a ball mark.  The group playing behind you and the maintenance staff thanks you!

How To Repair a Ball Mark


In last week's post I spoke about Gray Leaf Spot and its effects on the rough.  The recent cooler weather has stopped the spread of the disease, and we will begin overseeding once the rough dries out and won't be damaged by the overseeder.  Unfortunately, another disease has emerged due to the cloudy, damp conditions, and is affecting a few greens.  The disease is called Anthracnose, and is an opportunistic pathogen that specifically targets Annual Bluegrass (Poa annua).  I refer to the disease as opportunistic because it is always present in a golf course environment, but will only infect turf during stress-related periods such as weather events like we've experienced over the past 3 weeks.  Our weekly spray applications to the greens uses low rates of fungicides designed to stop the Anthracnose infection, but the recent environmental conditions necessitate higher rates that will stop the spread of the disease.  Our next fungicide application is scheduled for tomorrow, and hopefully the weather will allow us to get the sprayers out.  Once applied, we will see reduced disease activity the next day and the turf will start producing new leaves shortly after.

Another 1.19" of rain fell Monday into Tuesday from the remnants of hurricane Florence, bringing our total rainfall so far this month to 8.99".  That's almost triple our average rainfall for the entire month and we still have 10 days to go.  The excessive rainfall, combined with warm temps and high humidity, has created ideal conditions for a fungal pathogen named Gray Leaf Spot.  It's a devastating disease that we don't see very often in this area, and it's preferred host is Perennial Ryegrass and some older varieties of Tall Fescue.  Chemical control of the disease after seeing the infection is marginal at best, but we've sprayed most of the rough where infections have occurred.  Ideally, our roughs would consist of Kentucky Bluegrass and Turf-type Tall Fescue, since both are naturally resistant to the disease.  A few areas around greens will need to be sodded this fall, and the rest of the damaged areas will be overseeded with Turf-type Tall Fescue.  We've also stopped mowing the first-cut of rough around the fairways and greens to let the turf recover faster.

Course Update 9/13/18

The courses have dried out over the past two days, but there are still fairway and rough areas that remain too wet for mower and cart traffic.  The overcast and humid conditions, combined with very little wind haven't allowed the excess moisture to evaporate as quickly as we'd hoped.  However, as course conditions continue to improve I anticipate several holes being ready for cart traffic this weekend, as long as the isolated storms miss us.

I tip my hat to the staff once again and thank them for their efforts getting the courses, and especially the bunkers, put back together.  There's still a little more cleanup along the edges of some holes, but overall the place looks good.  I originally estimated a week to repair the bunkers, but this dedicated team had them done by Wednesday afternoon!  That allowed us to get the mowers out today and we made pretty good progress.  Fairways, approaches, tees and rough haven't been cut since Friday and there was a significant amount of growth.  Don't be surprised to see clippings when you play the next few days.  We have blowers out, but it's going to take several mowing cycles to get the turf back down to its regular height.  We also plan to have the mowers out both days this weekend, ideally ahead of play.

Please remember that fairway aerification is scheduled for Monday, Tuesday, Wednesday of next week.  Similar to this spring, a contractor will core aerify and cleanup the plugs on one nine each day, leaving 18 holes open for play.  We're waiting to see if/when the remnants of hurricane Florence will impact us, and will decide if the process needs to be rescheduled.

Course Update 9/11/18

As of this morning we've received 7.80" of rain since the first thunderstorm hit Thursday afternoon.  Most of the rainfall came on Sunday, all 5.50" of it.  The courses handled it well and there wasn't any major damage.  Mostly washed out bunkers and debris that floated out of the woods, along with creeks and ponds that were well over their banks.  It could have been a lot worse and the situation was helped by how dry the soil was last week leading up to the storm.

Unfortunately, the property still has a lot of water that needs to drain off and our regular maintenance activities can not resume until that happens.  This morning we were able to mow greens, change cups, and start repairing bunkers.  It will most likely take all week to get the bunkers back in playable condition due to the amount of sand that washed, and some bunkers still have standing water in them that needs to be pumped out.  All other mowing is on hold until later in the week when there is less chance to damage the turf from saturated conditions.  The good news is that the courses will be open for regular play tomorrow, and the maintenance staff is doing everything we can to resume normal operations.

Thank you for your patience!

New drain line on Orchard 8 upper fairway was overwhelmed by the amount of water coming down.  We were able to straighten the pipe and lay it back in the trench after cleaning up the sand and gravel that washed out

Several drain lines lost pea gravel due to the excessive volume of water flowing down them.  The good news is that we have the drain lines in the right spots to catch runoff that used to keep the fairways so wet

Pretty easy to see where the water came into the bunker

We opened the auxiliary drain on Orchard 2 pond to further lower the water level so surrounding areas could drain quicker

Course Update 9/6/18

Venting Greens: We took advantage of being closed on Tuesday and vented the greens using a spiker attachment.  The spiker blades penetrate 1" through the thatch and achieve a 2.5" by 2.5" spacing, with minimal disruption to the surface and putting quality.  While it doesn't go as deep as a traditional solid aerification tine, it still opens the surface for improved gas exchange and water infiltration, and at a much faster pace than our greens aerifier can go.  We were able to spike all 29 greens and collars in less than 8 hours.  We try to vent greens 2-3 times during the summer, based upon weather events and the amount of traffic the greens have received.

Grub Damage: It's that time of year when we begin to see patches of rough torn up by skunks and racoons that are foraging for white grubs.  The grubs are a juvenile stage of Japanese Beetles and Northern Masked Chafers that eat as much as they can now to survive in the soil over winter.  Then they emerge in the spring as adults, mate, lay eggs mid-summer, and repeat the process every year.  We proactively treat the entire property with a systemic insecticide in the spring, but inevitably there are areas that still become infested.  It could be from a skip during the application, or from extreme weather events that have been shown to reduce chemical activity.  Heavy rains in the spring and early summer have the potential to move the product from its intended location, while extremely dry, cracked soil can create voids in the chemical barrier.  Over the next few weeks we'll be treating the damaged areas with a different insecticide to kill any remaining grubs, then we'll clean up the damaged turf and spread soil/seed for quick germination.
