Best Grass Seed for Sunny Areas

I have some areas in my yard that may need some re-seeding this year. I was wondering what type of grass seed would be best for an area that receives a lot of sun. I noticed that some of the grass seed mixtures have creeping red fescue in them. I was told that this is not a good type of grass. Can I use just bluegrass seed or should I use a mixture with other types of grass?

You can use straight bluegrass if the area is 100 percent sun. Most mixes include a high percent of turf type perennial ryegrass for quick cover. Otherwise use a mix of bluegrass and fine fescue (this includes the creeping type). Most sunny grass mixes contain a higher percent bluegrass, perennial rye and some fescue. The fine fescue in the mix will fill in the shady locations. The perennial ryegrass will provide quick cover until the other grasses fill in. Reverse these proportions for shade. Select a grass seed with several varieties of bluegrass and fescue. Do not re-seed areas recently treated with a pre-emergent crabgrass killers. This herbicide will also prevent the grass seed from germinating.
