Anthracnose and the 18th Green

As many members have noticed our 18th Green looks weaker and thinner than any of the others. About a month ago we noticed some decline in the green and began to monitor the progress. Through numerous visits from colleagues and constant monitoring by management, it was determined that physical stress of a weaker variety of Poa Annua had caused the decline. The early, dry and hot spring put the weaker plants into an early onset of stress. Anthracnose is a turf disease that thrives on stressed turf grass. Even though we have been protected through Fungicide applications and fertility, Anthracnose set in on #18. We have sent samples into the Guelph Turf grass Institute to confirm our beliefs. Now that we are certain of the problem, we have began to bring the green back to life. Weekly venting and bi-weekly inter seeding with T1 bentgrass has already started to show promise of a full recovery. We will also be hitting this green in particular with a little bit more Nitrogen to aid in recovery. Luckily, the green is still playable. As always the patience and understanding of our membership is greatly appreciated.

The Practice Range Tee

Last fall we utilized a “new to us” method of revitilization for our practice tee. Our contractor TDS, fraize mowed the surface of the tee to remove organic matter as well at to aid in leveling. The tee was then aerified and seeded to a new variety of creeping rye grass. We chose this type of turf grass as research shows rapid recovery and a low growth habit. We were able to get some great growth in the fall, but the tee is still not ready for traffic and full use. The plan is to utilize the mats until growth has filled in some of the voids etc. We will then begin to slowly set up hitting areas on the grass tee. For a while we will alternate between grass and the mats with a 50/50 ratio of use. Once the grass tee is established and is in adequate recovery mode, the practice areas will be back to normal. As always our membership’s patience is appreciated as we try to improve these areas for use.

Greens Cultural Management Practices Schedule

The fall is a great time to perform a number of necessary cultural practices. Our goal is to amend the upper portion of the greens surface with enough sand to help insulate the crown through the winter as well as removing and diluting organic matter. Below you will find a schedule of cultural practices that we aim to complete before the covers go on and the snow flies!!! Wednesday, Sept. 30th- Light topdressing followed by a Cocoa matt Tuesday, Wednesday October 13/14-Course Closure full core aeration with heavy topdressing. October 19th- Light topdressing followed by a Cocoa matt October 26th- Light topdressing followed by a Cocoa matt November 2nd- Light topdressing followed by a Cocoa matt November 9th- Deep Verticut, followed by a sufficient topdressing. November 16th- Post Course Closure, Heavy topdressing followed by Deep tine aeration. Of course this is all in hope that the weather cooperates...happy fall!

Cultural Greens Maintenance...

With the cooler temperatures this week, we will be performing some all important greens maintenance procedures. Monday evening (after the outside event) we will be doing a light grooming on both our greens and collars. This task will help to reduce the amount of lateral growth, therefore standing up the plants (for a better cut) and smoothing out the surfaces. Following the grooming we will be dry mowing all areas tonight to help clean up the debris. Tuesday morning we will be applying our biweekly light topdressing prior to play. Once the sand has dried, we will use our cocoa matt to drag the sand into both the canopy and the shallow grooming channels created by tonight's procedure. These practices in conjunction help to create a smooth, firm and healthy surface to putt on.
