92 GOLF COURSE MANAGEMENT 07.19 John Mascaro President of Turf-Tec International The brown areas on this putting green near a poplar tree were obviously caused by tree roots invading the green and stealing nutrients and water from the turf. However, the interesting thing to note was that the previous year, the club's maintenance crew had trenched under the tree's drip line, cutting the tree roots and placing a barrier in the trench. However, the severed roots under the green had been so well-nourished with fertilizer and water that they took on a new life of their own and began to grow. These roots began sending up leaves that the greens mower was cutting off with each mowing, forming these white bristles in spots. The bristles were actually the remaining stems of the poplar tree leaves. The golf course's consultant speculated that if no one mowed the greens for a prolonged period, trees would have taken over the green and created a forest.

The damage in the photos is a reminder of how close we are to America's Independence Day, because what you're seeing here is fireworks damage. The damage occurred during a professional fireworks display that was put on as part of a confer- ence that was taking place at the hotel. The superintendent said this wasn't all that unusual because the hotel features fireworks displays five or six times a year, and the damage they cause and the mess the crew has to deal with afterward all depend on how the wind is blowing. Since the grass is zoysia and the course is in central Florida, no additional inputs were required to repair the damage, and the burned area healed over in about seven days.
