Two things always seem to get into my blogs; my age and my father. Both again are relevant to this post. When I was a kid 35 years ago, and my father was in the golf course business, I learned the lessons of growing grass in the "Transition Zone".
My father's course had bluegrass/fescue fairways and bentgrass greens. Now this course (Lake Tansi of old) was not built to USGA specs. It was basically push up greens and tees, and fairways were just cleared land. I remember the yearly diseases that dad would have, but I never remember his superintendent fighting heat related stress to any extent back then. In that same time frame I remember a vast bermudagrass winterkill in winter 1977-1978 all the way to Memphis. My whole point of this paragraph is: cool weather grasses thrived when I was young in the East Tennessee mountains, warm weather grasses were not even a remote possibility.
Fast forward to the summer of 2008, July. The 7th and final year I had a golf course. We had finally given up on keeping bluegrass/fescue tees healthy in the summer heat, stripped the tee sod on 12 of 18 holes in the spring and replaced it with bermudagrass. I don't know what strain as it was growing wild in our 18th fairway. The tees thrived the whole year. They had never been healthier. This year is the same story. They are no longer my responsibility, but they are perfect.
My quandry is this. I want to know from our superintendents out there if this story is an exception or the rule. Has the Transition Zone moved north due to global warming, 100,000 year heating trends,el nino, etc. or were warm weather grasses always welcome in the northern part of the south?
This is a subject I would love to discuss and have not been able to find anything on the internet. Please let me hear of your experiences with the "Transition Zone".
