Planted tall fescue and annual ryegrass at the same time on a bare part in my front lawn a few weeks ago and I am having some good results. However, I want to know which is is the annual ryegrass and which is the tall fescue. One is a lighter green, with a broad blade and is growing very good and thick. The other is a darker, finer blade and is growing OK, but not as thick. I assume the lighter green is the ryegrass, which was put down to provide quick establishment. Correct?
