I took over Maintenance supervisor for and outdoor resort on the oregon coast and the lawns and golf greens have been severely neglected. I have the plans for the lawns all in order and i see no issues on getting them up to grade. The issue is the golf course (chipping greens). What i walked into was a golf course supers worst nightmare, the entire golf course is watered on 5 zones using I-25's @ 20 minutes nightly for the rough as well as the greens, mow schedule of once a week in the same direction. Results from this over the last 5 years has devastated the course causing saturated rough and browned out greens with grass growth height at a whopping 2 inches+ from being rolled out rather than cut. As far as i can tell the last supervisor tried to fertilized with the same type and rate as the rest of the resorts lawns. What i did was order a salt resistant bent grass seed along with the correct greens fertilizer to try and save whats left as a complete rebuild is not in the budget. I plan to isolate the irrigation for the greens so adequate water can be used without flooding the rough. So, Here is the main problem. the greens have never been punched or sanded (12 years) resulting in a huge thatch problem,so bad that when i did punch the greens it literally tore the hell out of them like ripping up a shag rug. I am hoping that a fresh sand and seed will help but i am doubtful of successful results. Does anyone have any suggestions for saving greens with a huge thatch problem? Drainage is still adequate but getting all the organics out is troublesome. If budget was there i would just start over but this is an HOA resort and that's not gonna happen. They already know it's going to be a few years for a full recovery,after all they didn't get that way overnight. but i need to get them sorta playable at an amature level by late spring, early summer(ish). I am forced to use play sand for greens sanding as the only other sand available here is river sand (to course) and beach sand and the salt content would shock it to badly. I welcome any thoughts on this and can provide photos of what the thatch problem looks like, It ain't pretty.
