I'm a little late posting this, but the greens received a heavy verticut with a sand injection in march. It was decided not to aerate but to verticut instead. We removed a ton of organic material from this process. The greens will receive a light dusting of sand every 2 weeks during the growing season. Sometime in June we will follow up with a 1/4" tine to the greens to help them along the hotter months of July and August. The months of May , June, September and October will be a solid tine venting process. Next week we will be lowing the height of cut to the greens mowers which will be at .120. Greens should start to pick up speed in the next few weeks due to increased mowing/rolling and plant growth regulators being applied.
