As a follow-up to part 1 of this extraordinary interview with Don Mahaffey on Golf Club Atlas, here’s part 2. Don knows the golf and grass-growing business from the ground up, and he knows what he is talking about.

Update: I’m adding a note here today (21 Nov 2017) to correct and clarify about these data. Mike Richardson pointed out to me that the “differences from plots irrigated to field capacity 2X or 6X / wk were small and not significant” in this experiment.

@asianturfgrass many Japanese greenkeepers believe that syringing is effective to keep or lower leaf temperature. How do you think about it? — H.I.GK (@fc3s_13b) May 5, 2013 This question about lowering leaf temperature prompted an extensive discussion about the effectiveness of syringing greens.

That’s a bit of a trick question, because the answer I give is: neither. What one wants to do is apply the optimum amount of water to the turf, and that can be done by light and frequent irrigation, or it can be done by deep and infrequent irrigation.
