Chilling Injury

Although the winter of 2015-2016 has been unusually warm (winter temperatures did not even arrive until mid-January and many courses were mowing into December) the Northeast has experienced about a foot of total snow and a significant amount of rain during February.  Temperatures continue to oscillate between the 20’s and 50’s on a daily basis and while winterkill and crown hydration are unlikely, this shifting weather has resulted in a few cases of chilling injury.  Chilling injury is more common on bermudagrass but I’ve seen it on both Poa annua and creeping bentgrass/KBG mixes this winter.  Injured turf generally has a VERY unusual appearance, as if aliens has landed on it, and damage follows waves and curves.  Fortunately, injury is limited to leaves and plants recover quickly when incubated.  The clincher for this type of injury is that it occurs on surfaces treated for snow mold as well as on untreated surfaces.  While it can be ugly, quick recovery can be expected once the spring arrives.
