When I moved here the lawn was over run with weeds. With a couple of applications of weed and feed, it looks much better, but now I've discovered that it has about 5 types of grass. There are large patches of each type, with one type (thin needle blades) poking up almost everywhere. One is kentucky bluegrass, the rest I cannot identify. Could the bluegrass possibly overtake the others? How can I eliminate the others, and keep the bluegrass? Is this possible, or must I start it over? Any comments would be greatly appreciated. Thanks dwc Can anyone tell me where to find a website that has really good pictures of different types of lawn grasses? |

You might try to look up the "Scott's" web site. They claim to be the Turf Experts. It would help if we knew what state or at least what zone you are in. There are 1000's of types of grasses and each grows in specific regions. As far as getting rid of everything but the blue grass, (not knowing what other types you have) I would only weed and feed the blue grass that way it will be strong and grow better mayby invading the other grasses.

Thanks for the reply crabbergirl. I live in louisville ky. I think that is zone 6. I bought a little sod to fill a bare spot, and it was kentucky bluegrass, thats the only reason I recognize it. I'm from northern louisiana, and there, st. augustine was commom, but other than that I really dont know much about grass. The st. augustine put out runners that spread quickly, the bluegrass I dont believe does. The mixture of grasses looks awful to me, but starting a lawn over is probably more than I can handle. |

I dont have a lawn nor want one but for you in this case Id say, crabbergirl's suggestion might just be what you'd want to do. I personally would pull them up and let them grow in pots, and the ones I like I would keep, the others Id pull and compost. I truley love some grasses I have about 8 or 9 types that I grow, most of the green trailer ones I dont care for they go into the compost! It is going to be a job no matter which way you go about it. Hope all goes your way in the shortest peroid of time! If you cant start all over just mow them down and put the seed down that is right for you, slowly pull the little boogers out that you dont want. Right after a good long hard rain most should come right up for you. Have fun! Oh if you have a big enough patch of a certain kind you do not want just give a good jump on your shovel  They'll come out ,and put your seed. Dont forget to water the seed till they are a few inches tall which will take a while. Humm.. does it look that bad? Are you a lawn perfectionist, or just want a same looking lawn? I have perfectionist here for one, my FIL makes me crazy! His lawn is so thick you cant walk on it *lol Have fun... Kale

dwc, you can get a chemical call "2-4-D" which is used for dollar weed. Now if you spray in the heat of the day it will kill St. Aug. and may as well kill other less hardy grasses. Just don't spray on anything you want to keep. I think also you can use "atrazine" and it will kill some grasses. Look in the weed killer section of you local hardware store and read the lables. It will tell you what you can safely put it on and what it will kill. I am an organic gardener so I would go another route which is white vinegar. Spray full strength on what you want to kill off. It is actually cheaper than chemicals. If you have centipede it is one of the more hardy and prized grasses. A very expensive grass that resist bugs and drought. Very fine blades in a tightly woven carpet a lighter green than St. Aug. Gets very thick.Has thin runners just like St. Aug. Zoysia, which I have never had luck with usually grows well in shade or sun and is supposed to be like centipede but a darker green . Then you also have a lot of unknown junk grasses that will pop up it is so hard to tell whay you might have. Let us know what you decide to do and how it works. If you can post any pictures of grass samples may be we can identify them

There is no way you can selectively kill the non-bluegrass grass. You'll either have to live with what you have or start over, putting in a new lawn. Actually grass mixtures is the way to go. That way if disease hits one variety the others will survive. From a distance no one will ever know you have a mixed lawn. The major problem you may have is if any of the grass types are crabgrass. You'll know in a few weeks. If that's the case then you'll have to apply a crabgrass preventer (notice it says preventer and not killer) early next spring. |
