Good afternoon, and welcome to another Agronomy Weekly:
Anticipated Frost Delays
With the cooler nighttime temperatures moving in for the weekend, we are expecting frost delays Saturday, Sunday and Monday morning.
Over the past few weeks, greens height of cut has been incrementally raised to prepare for the upcoming winter months. The raising of mowing heights increases turf health and depth of rooting. Increased amounts of nutrients and fertilizer are applied on a weekly basis throughout this transition to ensure proper nutrition and increased growth.
Mowing, rolling and sand topdressing, along with other practices, assist with increased speeds and consistency as weather permits. Utilizing these practices throughout inclement weather can cause more harm than benefit, and green speeds may decrease for short periods.
After a few heavy frosts, the plant will go into dormancy, and consistent speeds will be maintained throughout the winter months. Based on the current weather forecast, we expect this to take place throughout this upcoming weekend.
Spots on Greens
You may have recently noticed spots on a few of the greens throughout the course. This infection is called Rhizoctonia Zeae, and also known as “Mini Ring.” Symptoms become visible with cooler temperatures throughout the fall when growth begins to slow.
The impact of this is mainly visual and does not cause any long-term damage to the plant. Treatments have been applied and increased fertility assists in the recovery process of the brown rings and patches.
Winter Hole Location Guides & Teeing Grounds
Our winter hole location guides and teeing grounds program will begin Wednesday, November 14th.
This program is used to reduce the amount of old cup rings on greens and conserve tee space throughout the dormant months. Three holes per green are placed, two of which are covered with a green rubber plug.
Locations will be rotated daily between these three holes. As winter hole locations 1-3 begin to show signs of wear, they will be alternated to winter hole locations 4-6.
Our five sets of tees will be reduced to three and moved as needed. This process helps to concentrate traffic daily and provide optimal teeing space throughout the upcoming months. They will be paired as follows: Bravo/Black Duke, Carson/Rocky Joe, Georgie Boy.
Bunker maintenance will continue daily to ensure uniform and consistent sand distribution. After each heavy rain, sand will be manually redistributed and liners tucked away.
Our goal is to increase sunlight to the shaded areas throughout the course. Our top areas of concern include #2, #4, #6 and #7 greens complexes. We begin by removing the underbrush (small trees, briars, etc.) growing too closely together, extensive limb removal, and removal of certain trees that prevent sunlight. Once these top priority areas are completed, tree work will continue throughout the entire course.
