To generalize and agree with TD, you cannot have "American standards" with bentgrass in the transition zone, poa in Philly, bentgrass in TX, etc without the use of handwatering. I believe that you cannot have greens on the edge, running north of 12 and not have a sound handwatering program in place. No offense to Joe, but having your grasses at much high heights GREATLY reduces the stress on a plant. If a green is being mowed at .156 as opposed to .090, the green at 0.90 is going to be on death watch without the proper water management. Same with fairways, tees and roughs. I know that when Joe was at Grand Island, he was not mowing at those heights.
JC-In most cases, 1 handwaterer isnt enough to get around a golf course and touch everything up when needed. The soils here at PT are made up of mostly a native loam. Prior to Mr. Wilson doing his work here, PT was an old pasture for dairy cattle. We handwater religiously here to try to get the tifeagle roots to search for water. On most days, you will see 3-5 staffers handwater tees, greens, apps and even fairways spots because the soils are so eradict-sandy spots, native, etc.
I would assume that Joe was on a "Deep and infrequent" water program because of labor costs, which is also a very good way to acheive the goal, but knowiing the Grand Rapids area, his soils were much more consistant what I what I've worked on at Long Cove or at Pine Tree. The soils were quite uniform at Colonial.
