PHOTO B: The yellow squares of turf were caused by something you probably wouldn’t have guessed. I too thought that something may have been left on the grass. As it turns out at this golf course in South Africa, they grow Kikuyugrass, a warm-season grass, on their fairways. In the winter, after some heavy rains, the superintendent was having some pooling of water on his fairway and instructed his assistant to remove some sod to see how extensive the problem was. After inspection, the same sod was replaced. When the summer came around, the turf turned brown in the same areas where the sod had been removed, creating these almost-perfect one-meter square areas. Apparently because the shallower roots, as well as these areas, have less root mass, the turf turned brown during the hot, dry summer. The surrounding root zone was obviously more established and could handle the heat stress better.
