We seeded a customers lawn and put down a "landscapers mix" grass seed. It contained a small proportion of annual ryegrass- but unfortunately, when it grew, too much annual ryegrass is sticking up all over the place, making his lawn look shabby. Coupled with all the rain we've been getting in the northeast, it only takes two days to look like a field again! My question is, can I get rid of the annual rygrass without harming the fescue and bluegrass this summer? My customer, of course, is one of those "I want it to look like a golfcourse, and NOW!" guys. We started with a soil test, found we needed lime and fert. added those, tilled, added topsoil and tilled, seeded with starter fert., mulched with straw, and have phenomenal amounts of grass growing, just that it looks shabby with the rye poking up all over twice as tall as the fescue and bluegrass!! Can anyone help me out with this? thanks in advance.
