My law has several large size patches inwhich grasses seem not growing. I'm going to do overseeding this spring. What kind of grass seed should I choose? Any detailed suggestons about how to overseed a lawn? Thank you!!

HI Minnie, many lawns took a beating last year with our weather. If it is full sun we look to Kentucky blue grass and perennial rye grass mixes with blends of different cultivars. http://urbanext.illinois.edu/lawntalk/ Here is a great website taht can give you alot more details. hope this helps.
