Aerification Schedule

As September approaches, it’s time to plan for aerification.   This is an important process to ensure the overall health of the golf course for not only the remaining part of this year, but also July and August of 2016.

Our primary objectives in aerating all of the playing surfaces include:

Gas Exchange

Thatch Control

Air/Water Movement

Compaction Relief

Aerification schedule for fall:

September 1-3- Pull plugs on tees and approaches

September 8-10- Pull plugs in rough

September 8- Seed Fescue

September 22-23- Dethatch/Verticut fairways

October 6-8- Deep tine fairways and greens

Because of the amount of thatch on the fairways, we will institute a new process called verticutting this year.  This will turn up A LOT of thatch on the fairways.  Follow the link to see the machine in action!

Notice the wavy appearance of the fairways- this is due to the amount of thatch that has accumulated on the fairways.

The above pictures were taken on a fairway.  Verticutting the fairways will help control this thatch.

This is a plug taken from an approach.  Note the difference in the amount of thatch (…about ½” at most). This is the result of regularly scheduled aerification.

Fescue Areas

Last year’s transition to Fescue in selective areas was very successful so we’ve begun the process of adding it in additional spaces.  It became especially noticeable this past weekend as the areas are beginning to die back.  The areas we are transitioning this year include: right of #4, front of #8, sections along the water edge (#8,behind #2, and right of #3), and #13. 

This process offers several sustainability benefits for golf courses.  Fescue provides not only an aesthetic component to the golf course, but also allows for:

-        Fertilizer Reduction

-        Water use reduction

-        Erosion control- acts as a buffer strip along waterways that helps filter nutrients before they enter the lakes

Addition of fescue along the water edge also assists with geese control, as the fowl don’t have an easy access point to the water.

The weeds in the fescue areas are becoming more noticeable (especially thistle and barnyardgrass).  We are using an herbicide that selectively kills the weeds and not the fescue grass.  The weeds are beginning to turn white since they are unable to photosynthesize.  Soon they will turn brown.  In order for this herbicide to be effective, 3-4 applications are required.

August 7, 2015 Scouting Report

August 7, 2015 Scouting Report The week that was left a mark on some of us that will be seen for years to come while a majority of courses as they read this line are thinking what is he talking about?? The storms that hit the northside of the city last Sunday left a mark in specific locations that left damage which will require time and patience in abundance. Bryn Mawr CC lost 100 trees in what looked to be a microburst while no one else came close to this type of damage. While a majority of the courses also commented that the 1” of precipitation that fell seemed to immediately disappear and that the conditions were still very dry. The ‘disappearance’ of the rainfall can be linked to the fact that evapotranspiration rates were as high as 0.25” of water per day late last week – that pattern has generally not changed this week as winds have blown disturbing the boundary layer around the turf canopy and temperatures have been more than warm enough to drive transpiration for cooling of turfgrasses. Once the cleanup of debris occurred this week, conditions rapidly turned to ideal as surfaces became firm and fast and once again bentgrass surfaces showed their true qualities and speed and smoothness were not an issue. Poa annua surfaces may have required more hand watering and possibly some courses raised mowing heights in an attempt to reduce stress – one of the problems of dealing with poa in the summer is trying to keep it alive! Roots on poa plants seem to be just about hanging in though summer patch has turned up and may be putting a final nail in the coffin. Reports of billbug larvae have also surfaced and with the dry weather we can expect to start seeing some damage from either digging or a distinct lack of roots which have now been eaten thus leaving foliage no way to draw water from the soil profile. Finally – the turfgrass field day is coming up on September 10th and with speakers coming in from around the region it promises to be an exciting event with plenty of opportunities to see the latest research. Further details will be posted next week on the CDGA website, but if you have any questions don’t hesitate to ask.

This week in pictures!

This past week we’ve finally been able to start work on some pending projects.  We finished the new runoff off the back of #6 green and began trimming trees again.

Removing the roots and prepping the area for sod

Laying bentgrass is much more time consuming than bluegrass sod

Almost done!

Finished product!  Maya is keeping a watchful eye to make sure it’s not drying out!
