Snow Mold Warning – Green Unlimited Lawn Saving Tips

There is definitely dead Poa annua that died of anoxia (too many days under the ice cover), Poa annua that may have died from direct low temperature injury, or crown hydration and even in some cases perhaps desiccation, not to mention snow mould and there may even be some damaged creeping bentgrass. Most of that brown turf may green up if its looked after properly.

On home lawns and sportsfields, there is plenty of snow mould injury but there is also the possibility of winter injury to our most susceptible lawn and sports turf species perennial ryegrass and tall fescue.

Next steps? 
Many of you are still in the wait until the snow is gone phase and until you have a handle of the extent of the damage it is hard to have a comprehensive plan. A light raking will speed up recovery, especially if we continue to have a colder than normal spring.  This will “fluff up” the matted dead grass allowing things to dry out and prevent suffocation of the crowns.

Extensively damaged areas may require some seed and soil. A common method on golf greens to achieve this is to core aerate, top-dress and seed to maximize the seed to soil contact.
