Had work in lawn, and ended up with subsoil of sand and clay as the surface, which I covered with rich soil from somewhere else on the property. Planted quick and quality grass seed, and it is doing great. Broadleaf weeds from the soil are mixed in. I know products exist to inhibit seeds from sprouting but is there a product I can use that will kill them but not the lawn grass? |

| Yes. There are selective herbicides. If you recently planted the seed, I wouldn't spray any kind of herbicide. Better to deal with it in the spring or fall. If you put down a weed and feed fertilizer that isn't crabgrass preventer, it will contain a non-selective herbicide. I don't recommend using weed and feed because I feel it's stupid to put down herbicide all over your yard when only a few spots have weeds. I don't use selective herbicides because, in general, they don't work nearly as well as non-selective. And there's no point in killing the weeds if you don't have any grass to put down in its place. If there's bare soil, another weed will soon fill it. What I do is in mid August, I get some roundup and kill the weeds and some grass dies as a casualty. A few weeks later, I clear the dead areas and put down grass seed. You can do the same in the spring, just move everything up 5 or so months. |

| Weed-B-Gone is one brand name of a selective broad leaf weed killer. It should work fine for you in NJ. I would wait, though for the new grass to become established. Next spring would be good. Selective spot spraying is better than granular materials. No weed-n-feed ever. Fertilize with fertilizer and kill weeds with weed killer. |

| knew I would get a quick response, but have not been able to get back. Aside from some clover, the weeds will, likely, with mowing, not be able to survive. They are things like pigweed, etc, that I think the grass will crowd out. |

| Weird thing is there is some kind of grassy type weed that has overtaken even the Bermuda. It sort of grown over it and smothered the Bermuda which I'm sure will still be there underneath, but the rhizomes of the weed have crowded out the Bermuda. It basically out Bermuda'ed the Bermuda. What type of weed/grass is this? |

| Clover used to be my enemy as well. "Used to" being the important words. After trying everything (I used to pull the white flowers!), to raking and manually removing, to ripping out whole sections of lawn, I finally accepted my fate and went chemical. Ortho Weed B Gon Chickweed Clover Killer was a game-changer. The concentrate is cheap (under $15), you mix a small amount in a gallon or two of water and spray with a backpack or bottle sprayer, and in about 2 weeks it just disappears, touching nothing else. It really is magic. But it does take much longer than most weed killers so just give it time. If after 2 weeks you still have some you can reapply, but I've personally never needed it more than once.
Pkapeckopickldpepperz, I think you posted in the wrong thread, but here's my recommendation for you: Without pictures my guess is nimblewill. This stuff is amazing at quickly choking out the wanted grass. There is an expensive but very selective agent that takes care of it exclusively (Tenacity), and I've personally used it to great effect, but it is not cheap (and not able to be used in all lawn types). Post a picture or do some detailed internet searching to determine EXACTLY what the weed is before selecting a treatment option. HTH |
