Courses are aerifying and overseeding greens to try and rebuild the grass. It's not that easy. We need warmth to let the grass take root and grow. Warm weather not just for one day, but for a longer time. We haven't had that yet.
People are out, wanting to play.
By playing right now, you are cutting the grass before it has a chance to really grow in. This fall, superintendents will be able to overseed as much as they want and the grass will have enough warmth to be able to grow and thrive. By mid-fall, everything should be back to normal. In the meantime, though, golfers shouldn't blame their superintendents if conditions aren't what they're used to. The bitter winter was the true culprit.
