It is getting to be that time of the year again. With a few frosts and cooler soil temperatures, we are starting to see the poa annua on the putting greens slowing down but the bentgrass is still growing. This is creating that same effect we discussed in the spring where the poa has a sunken appearance on the green.

| Poa is lime green and bentgrass is darker green |

| Poa has a sunken, less growth, more dormant appearance |
We had great putting greens all summer, so I guess we have to live with a few weeks in the fall as the greens transition to winter dormancy. The poa is not as hardy in the cooler weather so it enters dormancy earlier in the fall and comes out later in the spring. Putting the turf on the putting surfaces at two different stages in development this time of year.
