We used emerald for our collars, against the bent greens. It was not aggressive as far as encroachment. We did over seed for a number of years along with our tees. When we discontinued over seeding to allow our 419 tees to get healthy, we also stopped over seeding collars. Unfortunately, we had to re-sod many collars, especially those that had some shade. The rye became the dominate grass, as you would expect. I am no longer the supt. at that club, but the emerald is doing very well and I would still recommend it. In Georgia, it is difficult to get. Tiffeagle gets great reviews and you may want to contact those that use it.
