Help with Bent Grass in residential lawn...

    I'm trying to tackle 1 acre lawn in suburban Boston that is 50%+ Bent Grass.....

    I think a total overhaul would be too labor intensive and therefore cost prohibitive. By overhaul I mean spraying everything with RoundUp - using a turf cutter to remove the dead grass/turf - then re-grade and start with fresh seed/fertalizer.

    Does anyone have an alternative?

    Do you think I could "beat out" the Bent grass if I aerated and used a split seeder in the Spring and Fall next season?

    Any thoughts/comments would be very much appreciated.

    To get rif of the bent your going to have to spray something, correct? Why not use round up just skip the stripping and regrading process. Cut the seed into the sprayed lawn. Unless I am missing details why would you want to strip the lawn of dead grass? this technique is used all the time just get it done early in the spring so you have time to apply (and get good results) a pre emergent then seed again in the fall.

    I guess I thought all that dead grass will just become a thick layer of thatch in what I'd hope to be a nice new lawn... Would it not?

    Also, given the Round up is obviously going to kill everything - how long after it's dead would I need to wait to plant - - or is it's effectiveness essentially shot after it drys?

    Thank you for your response...much appreciated.

    Hire a licensed professional to spray the round up for you...

    The when the bent is dead slice seed an appropriate blend in...

    If you don't spray you will make the bent spread be severing the roots with the dethatcher...

    As I mentioned in a previous post - I'd be concerned that all that dead grass (from the Round Up) will just become a thick layer of thatch in what I'd hope would be a nice new lawn -- - should I be concenred?

    Also - who would I contract with to spray my lawn? Seems like a cross betwene pest folks and a landscaper :confused:

    bentgrass that has been there for a while and kept somewhere bwt 3-4 in. will probably have a decent amount of thatch but if you run the slitseeder in couple of directions, you should be fine. i've interseeded areas like that without a slitseeder before and had it come in nicely around greens. It all depends on your timing.

    Well, Take a core sample, that will show you the depth of the thatch layer. There are licensed people like me who can apply the product under our cat 37 license. If the property is North of Boston I could look at it for you or you could also go to www.lesco.com there are stores in Walpole, Milford, and Stoughton who could also direct you to a licensed applicator.

    Yes a professional to spray would be a great idea. I much agree with what mostly has been said. Bent grass is a fine grass thought i've managed all the time, but for the finest yard of bent at 1 acre would be a hell of a task daily!

    In New England bentgrass is an unwanted intrusion...

    To give you the short answers, no you should not have to worry about thatch layer and as soon as the round up is dry(sprayed in the am, seed in the pm) you can seed into it.
