The whole world was on a mission to remove grain from greens and some years ago HVGC went on a mission to cultivate grain back into their greens. Basically this was this initial brain-child of Linc Roden. He liked that old-fashioned "playability". From Linc's on mouth came the explanation that deeper roots should logically foster longer surface roots (grain). Linc does not like verticutting and actually thinks even HVGC does too much of it today!

Why doesn't the world like "grain" in putting greens? Probably for the very reason a guy like Linc Roden likes it so much---it's more complicated to play!
The new "A" and "G" strains? They're both a whole lot more dense than what preceded them (more leaves by far per square inch than their predecessors) (or at least that's the way they were developed to be).
The good news with the "A" and "G" strains is they love dryness and the fact that they're denser allows them to keep out poa longer. At least that's the reason we went to the "A" strain about three years ago----it was basically an added insurance program against constantly fighting anthracnose, or the prospect of it!
A grass that likes dryness and keeps out poa longer can be a whole lot less stressful for supers to maintain day in and day out. At least that's the theory.

Can the "A" strain have grain? Definitely. We saw some of that last year at Philly C.C. and definitely this year at White Manor. Obviouisly those clubs had not gotten into as regular verti-cutting programs as some of the other clubs that went to A1 and A4.
