Green Grows the Grass
Winter dormancy is settling in on lawns almost everywhere but the pampered ones in National Football League stadiums. The groundskeepers who maintain stadium turf have an especially difficult job this time of year because they are staving off the natural tendency of grass to retreat into dormancy and turn brown and stiff as winter approaches. Not only does that look unappealing on television, it is difficult for the players who have to compete on it. If the ground becomes frozen hard, natural turf can be as dangerous to players as the old artificial turf fields which had insufficient cushioning beneath them.

Modern NFL stadium natural turf stays green into December and January because groundskeepers take measures to prolong its growing season, from heating systems underneath to grow lights overhead. They effectively keep the grass in a condition most homeowners have not seen in their lawns since September. The “frozen tundra” of Lambeau Field in Green Bay, Wisconsin, is a memorable phrase evocative of the hard knocks of winter football outdoors in the upper Midwest, but it hardly applies any longer to the actual playing conditions considering modern turf management techniques.
For the average homeowner who looks out at a brown lawn throughout the winter (when it’s not covered in snow), the remedy lies not in trying to replicate the green turf of NFL stadiums. That would require an enormous input of money, time, and effort equivalent to what an NFL franchise invests, albeit considerably scaled down. Better to let the grass go to sleep for winter, but to tuck it in with some lime, some compost, maybe a light application of preferably organic fertilizer, and then a last mowing at a short setting to mulch the last of the fallen tree leaves. For the rest of December and January it’s time to settle into a comfortable chair in the warmth indoors and watch the football games on TV play out on the greener grass of early fall, maybe with snow falling on it for added dramatic effect.
