Poa control

It is no secret that bentgrass survives longer under winter ice than Poa annua and that turns out to be a nice advantage on our newer bentgrass greens on the Greywalls.   This is the only location that I found significant ice this winter under the 2-3 foot snowpack.  The ice accumulated after a December warmup and just happened to be on the first tee putting green.  This is also the location where Poa is highest on the Greywalks greens because it is planted there by golf shoes.  The spikes on golf shoes pick up Poa seed from the Heritage or other courses and then they are planted on the first few holes as golfer play.  This is a fine example of why it is so very important to clean your spikes at the Proshop after every round.
