Members Club - Aerification week

      This week the Members Club will be closed to deep tine their greens. Deep tining is a form of aerification that does not pull cores. This method uses solid tines and reaches depths of 8 or more inches depending on the soil type. The purpose of deep tining is to reduce compaction and improve the drainage of the green. Deep tining is recommended at least once per year along with traditional core pulling aerification.
      While the Members Club is closed there are some other projects we will attempt to complete. Here is a rundown of our goals for this week.
  • Verticut greens
  • Topdress greens
  • Apply gypsum - Gypsum helps to flush the accumulated salts from the soil. Here is a link explaining the benefits of gypsum.
  • Apply nematicide 10,13,14, C9 - Nematodes are root feeding parasites. These pests can be extremely devastating. Here is a link to my previous post on Nematodes.
  • Fertilize greens (18-3-16)
      With the cooperation of Mother Nature we will be able to accomplish all of these tasks by week's end. The ability to close for these processes is a testament to the exceptional membership at St. James. We truly appreciate your cooperation with the agronomy department as it pertains to golf course maintenance.

Bunker rakes - In or out?

This question has been asked over and over and over again. Multiple facilities, private and public have dealt with this debate in some form. Although there is no rule in place, here is the USGA's take on rake placement.

Q. Should rakes be placed in or outside bunkers?

A. There is not a perfect answer for the position of rakes, but on balance it is felt there is less likelihood of an advantage or disadvantage to the player if rakes are placed outside of bunkers.

It may be argued that there is more likelihood of a ball being deflected into or kept out of a bunker if the rake is placed outside the bunker. It could also be argued that if the rake is in the bunker it is most unlikely that the ball will be deflected out of the bunker.

However, in practice, players who leave rakes in bunkers frequently leave them at the side which tends to stop a ball rolling into the flat part of the bunker, resulting in a much more difficult shot than would otherwise have been the case. This is most prevalent at a course where the bunkers are small. When the ball comes to rest on or against a rake in the bunker and the player must proceed under Rule 24-1, it may not be possible to replace the ball on the same spot or find a spot in the bunker which is not nearer the hole — see Decision 20-3d/2.
If rakes are left in the middle of the bunker, the only way to position them is to throw them into the bunker and this causes damage to the surface. Also, if a rake is in the middle of a large bunker, it is either not used or the player is obliged to rake a large area of the bunker, resulting in unnecessary delay.

Therefore, after considering all these aspects, it is recommended that rakes should be left outside bunkers in areas where they are least likely to affect the movement of the ball.

Ultimately, it is a matter for the Committee to decide where it wishes rakes to be placed.

From a purely maintenance perspective, the rakes would be placed inside the bunker. This would reduce labor time by eliminating the need to stop the mower and move the rakes. However, we do not work at a turf farm. We are a golf course and the players perspective is the only viewpoint that matters. With that said, the membership needs to agree upon there desired location.

PC Conversion Update - 8/12

      Less than 24 hours and the Players Club is open again. It's been a grueling, but rewarding summer. We are very excited to finally unveil the new greens to the membership. The greens rolled (9'4") on the stimpmeter on Saturday morning. We anticipate a (9.5') roll on Monday. Here are some pictures of the surface on Saturday.


      Here are two pictures from five weeks ago, only one week removed from planting.



     The photos illustrate just how far we have progressed in a short period of time. On Monday you will be able to experience for yourself the quality of the new putting surfaces.
    
     In our final week of preparation mother nature decided not to cooperate. The inconvenient rain events pushed our work schedules into the evenings on Friday and Saturday to accomplish everything we wanted by Monday. Here is a rundown of the final tasks leading up to opening day.

Last Week 8/5 - 8/11
  • Monday - We mowed the greens at (.140") today. The staff continued their bunker work (mow, edge, redistribute sand). We also started our edging work today (cart paths, yard markers, etc..).
      Another project that began today was the edging of the green surfaces. This task is new to the Players Club this year. The goal with edging the greens is to prevent encroachment from the collar turf. The collars consist of 419 bermudagrass. In years past there has been a major encroachment problem at the Players Club. We feel strongly that regular edging will prevent any future issues associated with edge contamination.

After the green edging.
  • Tuesday - Mother Nature washed us out on Tuesday. She dropped nearly three inches of rain over the course.
  • Wednesday - Today brought some more rain onto the Players Club. The course was completely saturated thus limiting the amount of work done for the second straight day.
  • Thursday - The greens were cut at (.130") today. The average golf course green is mowed at (.125). Our target height is (.120) for opening day. Thursday also allowed us to resume our bunker and edging work.  
       We were able to make our first growth regulator application to the greens. The growth regulator helps to maintain green speeds throughout the day. Without regulation the surfaces would grow, unrestricted. The result is fast surface in the morning and a slower ball roll in the afternoon. There are many agronomic benefits to growth regulation as well. However none more important than ball roll consistency.
       We topdressed the greens as well Thursday. Instead of using our sand/peat mix we switched over to straight sand. This sand was designed specifically for MiniVerde greens. The sand is of fine texture. This texture allows it to work into the tight MiniVerde canopy. This sand will help the greens to maintain smoothness and correct imperfections on the surface.
  • Friday - We dropped our height of cut to our target of (.120") today. We saw some increased scalping and discoloration. These signs our normal when mowing this low for the first time. Increased frequency, growth regulation, topdressing and rolling will correct this issue over the next few days.
      We applied insecticide to the course perimeters today. Our target pest is armyworms. Armyworms our very small pets that feed on the leaves of bermudagrass. They overwinter in forested areas. Upon hatching they move into grassed areas to feed. Armyworms get their name from their feeding characteristics. Literally thousands of worm can be seen feeding on leaves at any one time. From a distance the turf may appear to be moving as you approach the affected area. These pests can be devastating to turf if left untreated. Typically, one to two applications are necessary per year to reduce the damage done by armyworms. Here is a fact sheet with more information on armyworms.
  • Saturday - Today we made a wetting agent application to the greens. This particular wetting agent is designed to help move water through  the soil. The increased movement will help to dry the green and provide a firmer putting surface.
      Saturday could be categorized as cramming for the big exam. We set up all the golf course hardware, cleaned debris and wrapped up all ongoing projects. This was our final full working day before opening. We will be hosting a small group of players on Sunday and we wanted to present the entire course in the best condition possible. Tomorrow we will set up the course as usual and watch as our hard work this summer can finally be enjoyed.

      This post will wrap up the Players Club conversion series. Stay tuned throughout the remainder of the summer and fall for more news from the St. James agronomy team. We will continue to use this blog as a tool to communicate our operations and projects to the membership.

The snakes of St. James



 This time of year is prime condition for snake activity. While most snakes are nonvenomous, the few that are can be extremely dangerous. In this article I will provide you with information concerning the poisonous snakes common to St. James Plantation.

Copperhead
      The copperhead is the most common venomous snake in North Carolina. Copperheads are marked with dark brown, hourglass shaped crossbands on a light brown or gray body. Their stomachs are a mix of white and red markings. Copperheads typically feed on mice, small birds, insects and frogs.
      These snakes are commonly found in wooded areas. They are tolerant to humans and can be found in wooded developments.
      When copperheads are disturbed they will vibrate their tail. If severely threatened they will usually bite to defend themselves. Although painful, their bites are rarely fatal to humans.
      Here is a link with more information about copperhead snakes.

Cottonmouth "Water Moccasin"
      Cottonmouth snakes are semi-aquatic snakes with dark crossbands on a olive to dark brown body. Cottonmouths are most active at night and feed on rodents, frogs, fish and other snakes.
      Water moccasins are typically found in or near aquatic environments. They prefer swamps, canals, and slow moving streams and rivers.
      When disturbed a cottonmouth will usually try to escape their enemy rather than biting. However, if severely threatened, this snake will bite. The cottonmouth's venom is very toxic and bites can be severe.
      Here is a link with more information about cottonmouths.

 Rattlesnake
      Rattlesnakes are the most common poisonous snakes in the United States. There are 30 different species of rattlesnakes. Three of them are common to southeast North Carolina.
      Rattlesnakes can vary in color and size depending on their location and diet. The common trait of these snakes are their rattles. These rattles serve as a warning sign for enemies to stay away.
      The eastern diamondback, timber and pygmy rattlesnake are the most common rattlesnakes to North Carolina coast. Here is a link with more information on rattlesnakes.
  • Eastern Diamondback
      The eastern diamondback is the largest of the rattlesnakes and the most dangerous snake native to the United States. The eastern diamondback is marked with dark diamonds outlined on black running along their gray or yellowish bodies. Diamondbacks have two light lines running along the sides of their heads.
      Diamondbacks are typically found in sandy pine flat wooded areas along the Coastal Plain. Diamondbacks are ambush predators and usually feed on rodents and rabbits. As of now this particular rattlesnake is protected in North Carolina.
      Diamondbacks depend on their camouflage and try to remain undetected when danger is near. Even if disturbed, most diamondbacks are reluctant to bite and will try to escape first. If they can's escape they will rattle loudly as a warning, and if necessary will bite.

Eastern Diamondback distribution

  • Timber 
      The Timber rattlesnake's key characteristic is a solid black tail. However, there is considerable variation in overall color depending upon location. In mountainous areas this snake is usually yellow, dark gray or almost completely black. The timbers in the Piedmont and coastal regions have a pinkish background and often a brown or orange stripe running down their back.
      Timber rattlesnakes are commonly found in forested areas. They will often hibernate in large numbers. Timber's are ambush predators that feed on rodents and sometimes birds that venture too near to them.
      Similar to the Eastern Diamondbacks, timbers are reluctant to rattle or bite. They too rely on their camouflage for protection. The timber rattlesnake's venom is extremely toxic, and deaths from bites have been reported.

  • Pigmy
      Pigmy's are the smallest species of rattlesnakes in the United States. This snake is usually gray with a row of dark spots running down its back and along its sides. The pigmy's rattler is so small that its rattle sounds like a small insect.
      Pigmy rattlesnakes are very rare, but can be found in pine flat woods and scrub oak habitats. These snakes feed on lizards, mice and frogs.
      Like other rattlesnakes, pigmy's rely on their camouflage for protection. If threatened and unable to escape a pigmy rattlesnake will bite to defend themselves. Due to its size this rattlesnake's bite is generally less serious as opposed to its larger relatives. However, if bitten you should still seek medical attention.

PC Conversion Update - 8/5

      Only eight days remain until the Players Club reopens. We have now shifted into full course preparation mode. The coming week will see us wrap up any ongoing projects and prepare the course for play. The greens are in excellent shape and will be 100% ready for golf on August 13th. Below is a picture of the Players Club practice green on Friday.


      You can see that the green's have come a long way in six weeks. We will shift our focus next week from growing to grooming the greens. The grooming will help to increase speed and maximize playability. Here is last week's recap and a look ahead to next week.

Last Week 7/29-8/4
  • Monday - Today we mowed the greens. We cut at (.150"). This height allows us to benefit from the increased leaf tissue. We will rapidly decrease the height next week to prep for play.
      We fertilized the greens today with (22-0-22) fertilizer. This fertilizer will help restore potassium levels and keep the turf green and vigorous.
      On Monday we also began to prep the bunkers. We started mowing the banks, edging and redistributing the sand. Redistributing the sand is a job done on a biannual basis. The sand gradually works itself to the lowest points of the trap. This results in increased sand on the low side and virtually no sand on the high sides. There is plenty of sand in the bunker, however it has worked itself to the low points. Our job is to move the sand from areas where there is too much back to where there is too little. We strive for a depth of four inches throughout the bunker.
  • Tuesday - We dropped the height on our mowers today. We mowed the greens at a height of (.140). We will remain at this height until next week. At that time we will drop the heights to an acceptable playability level.
      We aggressively groomed the greens today. We verticut the greens at 1/8". This means that we sliced the surface at a 1/8" depth. This will promote lateral growth and better assist the surfaces to fill in.
      Today we spread lime over the entire golf course. Lime (CaCO3) helps to raise the pH of the soil. the increased pH level will help in increasing the availability of certain nutrients to the turf. Here is a website explaining the benefits of lime in turf.
  • Wednesday - Today mother nature did our work for us. Six inches of rain dropped on the plantation. Although we lost a work day, the rain was much needed and greatly appreciated.
  • Thursday - We mowed the greens today at (.140"). As stated we will remain at this height until next week.
      The rain and ensuing humid conditions increase the chance for disease and algae. Today we applied a contact and systemic fungicide to help prevent the onset of any diseases.
      Today we also continued to work on the bunkers and make some more progress on our sight line projects.
  • Friday - Mowed greens at (.140"). We also topdressed the greens today with a light layer of sand/peat mix. The topdressing will help to fill any remaining voids on the surfaces. The peat will help to keep the moisture at the surface. The retained moisture will encourage new plants to fill these sand voids.

Next Week 8/5-8/11
  • Continue bunker work. (edge, mow, redistribute sand).
  • Edge cart paths, sprinkler heads, and yardage markers.
  • Verticut the greens.
  • Groom greens with mower attachment.
  • Roll greens.
  • Mow out the entire course.
  • Apply growth regulator to the entire course.
  • Continue fertilization of weak areas throughout the course.
      The coming week will be our busiest and most enjoyable so far. Nobody is more excited to unveil the new and improved Players Club than the maintenance staff. We will all be working Monday to Monday to ensure that we provide the best playing conditions possible on the 13th.
      Remember to follow the blog for updates on everthing St. James agronomy.

Reserve Club Update - Bunker sand

      This past week at the Reserve Club we have been able to begin a bunker restoration project. We plan to restore multiple bunkers on the course over the next several weeks. The first bunker that we completed was the pot bunker near #5 green.
      The restoration project starts by removing all of the old sand from the bunker. The old sand is removed to prevent contamination of the fresh sand. We remove the sand until we reach the native soil.
      The next step is to begin adding the new sand. We add the sand at a depth of four inches. This is the standard USGA bunker sand depth. As we add the sand we are constantly tamping as we progress. The tamping helps to compact the sand, therefore reducing the chance of washouts. Below is a picture of Assistant Superintendent Michael Gore tamping the sand.


     Here is a picture of the finished bunker.

   
      Although easy to demonstrate and narrate, this is not an simple job. Re sanding a bunker is extremely labor intensive and time consuming. A small to medium bunker may take a full day complete. We plan to continue this project throughout the summer and fall. We will be addressing the bunkers in a priority based order. Continue checking the blog for updates from the Agronomy team at St. James.
