The 2 most common grasses in Kansas lawns are Bluegrass and Tall Fescue. Most all the yards in the area will have a mixture of Fescue and Bluegrass. Unless you are really concerned with having one or the other you probably have a mix of the 2 in your lawn. Both have their benefits one more than other. Most of the time is comes down to what you like. Here at Aspen we only seed with a tri-blend Fescue unless the customer wants another blend. The reason we use Fescue is because of its hardiness. It is very tolerant against, drought, disease and it is a lower maintenance grass to keep it green and healthy during the year. Bluegrass is a good looking grass but very high maintenance is involved in this area of the country. Bluegrass likes to stay wet so lots and lots of water to keep it green. It does not do very well when it comes to fungus it is very susceptible compared to Fescue. The big benefit to Bluegrass is its ability to branch out and grow since it has Rhizomes which allows it to spread and fill in areas. Unlike Fescue which doesn't spread it is bunching grass.
In the picture to the side it shows what the grass looks like and how to figure out what grass type you have. The 2 biggest differences that you can see:
1) Bluegrass has a smooth boat shaped tip on the grass blade and Fescue has rough pointed tip on the grass blade.
2) If you pull the leaf off the stem of the grass you will see one of 2 shapes a triangular or round shape on the leaf. The picture shows what that would look like.
Hopefully this will help you find out what grass you have in your lawn. If you have any questions about grass types feel free to call. 829-6136
