    any ideas how to keep this from happening after the mulch has already been put down? will the grass under the mulch eventually die out?

    Round-up. Eventually, if the mulch is thick enough, the Round-up will kill the existing grass, and the new grass/weeds won't have a chance to germinate.:)

    the mulch is surrounding some pretty good size bushes. wouldnt the roundup hurt them?

    As long as the Round-up doesn't get on any of the foliage of the shrubs, you'll be fine. If possible, cover them with trash bags or something because drift can be a killer. As soon as you're done with spraying, take the bags off.

    Remember, Round-up does absolutely nothing to the soil. It attacks the plants by entering through the foliage. Good Luck:)

    The Round- Up is not good for the shrubs and will kill some depending on what the shrub is and how much Round-Up gets on them. If it's possible you can get a piece of cardboard or plastic and try to shield the shrubs when you spray . Try to spray on a day that is not windy. Another technique I have heard that works is to mix the Round-Up in a bucket and use a "Rag-type mop" and brush the Round-up on the weeds, but I have never tried that technique and wonder if it is really feasible. What kind of grass is coming up under the mulch ?

    So you laid seed down, put down starter fertilizer, then mulched over it?? This is bark mulch we are talkng about, not a seed starter (Penn) mulch we are talking about, right??

    I did the same thing for a HOA ta few weeks ago. They were putting in a sprinkler system along their community center & in some islands. Then called me to overseed everything. I came back a week later to check up on it & someone had mulched over it?!?! Oh well, now I added that location to my bi-weekly landscape weed control tha tI do for them on all of their entrances.

    when i put the seed down i wasnt completely sure where we were going to put the mulch. these are some brand new bushes, rose of sharon, holly, and 2 othere kind i cant really think of, theyve only been in the ground for about a week. would it be better to dig them up and then use the round up?

    Look in a good garden center. There are products that kill grass but not broadleafs or shrubs. That's your best bet. Digging up plants that have only been in the ground a short while is going to stress them a great deal. They might survive, but I doubt it.

    Seems a little funny to me that RoundUp is the only option that gets mentioned on this forum. Why use a shotgun when you need a sniper rifle?
