Sometimes, ignorance is bliss.....
The decision is either have the Open at Pebble....or don't. The greens at PB are always questioned compared to all the other course the prima donnas play, because of the Poa annua present, and the climate they are grown in. End of story. There is nothing else they can do to make them as perfect as Paul B's greens at Muirfield Village. The crew at PB probably spends as much, if not more than any other golf course prepping for a major. Greens are conditioned to the highest levels of our industry. As Supers, all we do is work with the environment, and as Tom Doak earlier stated, bentgrass will not proliferate in that climate. So, Poa is what you get, and it is a Poa similar to late April to mid may of the East....far from perfect.
Poa is the grass they are putting on. If it "goes dormant," it is DEAD. If Poa disappears on my greens in Rhode Island, so does our membership, our play, our revenue, and my paycheck, because the greens are dead and gone. No one sprays a miracle chemical to eliminate the Poa, because of you kill it, all grass on the greens goes away. Yes, we spray for seedhead suppression, as I am sure Pebble's greens have been, but it is a huge misnomer that the Poa just goes away. Chances are, you are putting on Poa on your older golf course and you just don't realize it.
