How do I kill creeping bentgrass?

My lawn is starting to get over-run by creeping bentgrass which is immune to Roundup and any other weed killer I know of. The bentgrass looks ok during the growing season but turns completely brown in the winter months. I just have large patches of it so far so I would like not to plow up the whole yard and start over. And even that probably would not get rid of the bentgrass.

One question...





Are you sure it is creeping bentgrass?





From your description, it sounds like a Zoysia grass.





Zoyzia grass exhibits the browning in the cooler months and loves summer months.





Either way, you have a problem.





Their is not an y easy way to selectively kill bentgrass or zoysia grass.


Non Selective controls like Round-up are the only way to go. It will also kill anyother grasses in there too.





Some advice (Dont worry,I'm a professional %26amp; have done this successfully):





Non selective weed control products dont work very well when the target plant isn't actively growing. If you have are spraying, you need to make sure it is in the active growing season.





Make Sure you are using a good concentrated Round up you can mix yourself (at the proper rates) instead of a ready mix trigger bottle.





For either type of invading unwanted grass, I have sprayed 2-3 times to make sure to kill it all. After 1 week, I respray, and maybe 1 more time depending. This is important, because if you leave just a bit of a root or rhyzome in the soil, it regrows back.





After 2-3 times spraying , it is best to spade it out if it is a small area. If not, you may cut it low(the dead grass) and seed into it with an overseeder, or rent a sod cutter after a week of you last spray job.





Make sure you properly seed your lawn afterword.

You must be diligent with these creeping grasses.





After seeding and you have grass, keep an eye out for any invaders while mowing next year. If you see a small cup size spot appear, just give it a tiny shot of ROund-up (one of the only times I recommend spraying round up in a lawn). If sprayed while it is 3 inches in diameter, youll never notice the tiny dead spot and you will be on top of any new invaders for years to come.





Hope it helps...
Reply:tear out all of the grass u dont want and take something to dig a hole. dig a hole and put seeds in there. do the rest wit d other part of da lawn. i did dis before.
Reply:Use Roundup more than once as the previous answer states. Squirt some dishwashing liquid in your sprayer with the Roundup and it will work better.
