Poaannua is found from the Arctic Circle to the equator , says Dr. Zac Reicher, a specialist with the Bayer Greens Solutions Team. “It is more than capable of surviving in a wide variety of climates,” he says. “This is largely due to the tremendous genetic variability of the turf species and its plasticity, or the ability to adapt to its surroundings and cultural management practices. Depending on the climate, Poa may be the best-adapted grass, poorly adapted, or anywhere in between. Furthermore, it may thrive in the summer in some areas, spring/fall in other areas, or all-year-long. Plus, every golf course has a different environment of soil types, shade and humidity. Add to this that all courses have a different level of ‘acceptable’ Poa population and/or performance, and one quickly realizes that Poa management programs vary dramatically from course to course and region to region.”
What is the name of the golf course in Bethlehem, PA?

But the Poa returned and Chessard is fine with that. “I’m probably a better Poa farmer than I am a bentgrass farmer,” he says. “A lot of it is dictated by the microenvironments on your golf course. The reason we regrassed was because we were doing a bunker restoration and the greens had shrunk somewhat. We wanted to recapture the original size. We had great greens going into that. It takes a while, especially in this climate, to really let bentgrass grow in. You need a good 12 months of growing, which is essentially a season-and-a-half, almost two seasons of growth.”
