How to deal with clumps of unwanted grass?

    I had to add a bunch of topsoil to an area of my front yard last fall to fill in and area that had settled over the years. I re-seeded the hell out of the area and for the most part, it has come in nicely. However, there are clumps of, what appear to be, K31 scattered throughout the area. I am wondering what the best method is to deal with these clumps and the best time of year to do it. Each clump is the size of a baseball of softball.

    1. Hit each spot with roundup and re-seed a few months late.

    2. Dig each spot up, refill with bagged black dirt, and re-seed.

    3. Pull up each area the best I can by hand and just overseed the hell out of the area.

    Thanks for any advice.

    If i were doing it, I would hit it with Roundup. Wait 10 days and hit it again with Roundup, then wait a few days and reseed.

    I thought I heard somewhere ground is not good for re-seeding for 6 or 8 weeks after using a product like round up. If that's not the case, that's great news.

    After using roundup you can re-seed the next day.

    Good old fashioned roundup (not extended control or brush) work on the green leafy part of the plant. It will not affect ungerminated seed at all.

    2 and 3.

    Is it warm enough to use R-up?

    Just get a spade and do the work.

    It's your lawn, do it right. #2. It's not that time consuming you just have to put in the work and you already know that will get the best results. You'll thank yourself later for doing it right.
