That would probably be our biggest concern, the cool season rough we have here in the transition zone, with not much irrigation. I wonder about taking some of the USGA approach to a graduated rough, of course there would be more of equipment or at least training needs, or maybe some playing with heights of cut entering into the summer season, (of course this past year that would have been March). I did see some great cool season roughs this summer in our area, I'm guessing they had great irrigation coverage, not a lot of traffic, and a little higher height of cut as well? ( i know a couple of spots on our course where irrigation coverage is good and no traffic we saw some too). Then I would also have to deal with bermuda spreading out there, (of course there is a lot out there now). I do know we are spraying some vessel now and the cost per acre is under $20, maybe down as low as $11 depending on my rate.
I think fertilization would be a big part of it too, when I was up in northern Indiana, we fertilized our roughs pretty heavy my first season as I was trying to get some grub damage healed. We mowed at 2" and had decent irrigation and natural rain fall. Had Dr. Riecher from Purdue come up to look at the course and asked me what we used for pre-emergent, I said we didn't, we couldn't afford it, so my clue was fertilizer is a pretty good pre-emergent? I do think our biggest problem here is lack of fertilizer in roughs, we haven't done it since I've been here and doubt it had been done before that.
