The Threat of Winterkill to Zoysia Grass-Now a Reality

As you look around the landscape of the neighborhoods near Hyde Park, Mother Nature after a long winter has left her mark with many damaged/ dead plants including turfgrasses. As discussed, back in February in an earlier update http://hydeparkgolfandcountryclub.blogspot.com/2014/02/update-cold-temperatures-and-zoysia.html the threat of winterkill was a concern and unfortunately is now a reality noted on some of the fairways particularly where water was sitting due to poor drainage, heavily shaded areas, high traffic areas and newly sodded areas.

The worst hit areas are located on right sides of the 9th and 18th fairways. Due to the extensive shade in these areas the plant is weakened, and was unable to stand-up to the extremes of Mother Nature. These areas will evaluated with further shade studies measuring intensity and duration of light for long-term solutions that will be discussed at future Grounds Committe meetings. In the short-term these areas will be resoded and played as ground under repair. Below are few images outlining theses areas on the 9th fairway.

Areas similar to the above picture will be aerified in the declined areas and we will patently wait for the warmer temperatures to come. When operating golf carts please try to stay away from these brown areas.

The recovery strategy of the Zoysia grass will include:

  • Aerifcation of the fairways in June or July
  • Deep tine aerifcation of all the fairways beginning in June
  • Sod
  • Reducing traffic in declined areas
  • Added fertilizer treatments
  • Patience
