In my two years dealing with warm season grasses, I've seen/heard both sides as to which is the better grass and also painting vs overseeding.
Here at Long Cove, we have TifEagle. It was installed in he summer of 2001. Though great in the beginning, as some people have echoed, it is a very maintenance intensive grass. We have to do A LOT of topdressing, A LOT of verticutting, A LOT of aerifying, A LOT of brushing all to get the greens to be somewhat smooth and somewhat quick. TifEagle seems to be a thatch maker. We aerified 2x this year with 5/8 hollow tines on 1.5 x2 spacing and quad tined with 1/2 inch tines and we don't think that we really gained any ground on the thatch. The USGA recommends removing up to 30% per year. During our AJGA Tournament of Champions this summer, we did a combination of grooming and brushing, along with mowing greens 33 times in 10 days and they were VERY good,(11.5 on the stimp) but 2 days after the tournament, they were back to there 9+ on the stimp.
Overseeding Vs. Painting
IF the greensites are open enough-morning sunlight, not completely surrounded by mounds and have very strong turf from the summer, painting can be achieved. The biggest reson for not painting is traffic. Long Cove does well over 60% of our rounds (33,000 average) from October to April, which is currently on our overseed. That's just under 20,000 rounds. The courses in my area that paint do less than 20,000 rounds for the year. The problem with painting that if the greens were to thin out because of traffic, they will not be able to fill in til late April at the earliest. I know alot of clubs wouldn't tolerate this. We are letting one of our putting greens go dormant this year as a test green. We're going to paint it, but it's gets a lot of use and has shade issues. Time will tell. I will say that it seems like Champion is more shade tolerant that TifEagle. I think that courses need to be careful with the "No Till" because if the subsurface hasn't been taken care of over the years, trouble could persist down the road. I would make sure that a very good topdressing program was in place prior to using the "No Till."
