    I don't do any chemical applications as part of my business but I am installing a new lawn for myself and was wondering if there was a premergent I could put down before seeding. I really didn't have a weed problem in the past but raised the grade with about 3-4 inches of top soil and I would like to prevent crab grass and such before it is a problem. How long after the application would I have to wait before seeding if the soil was watered frequently? Thanks for any information.

    Thanks, I did want to seed as soon as possible but figured if there was any preventative steps to take now it would be worth the delay. Thanks again.

    Dont put dimension on new grass. If you need a Pre-emerge wait till fall to ensure full growth potential.

    Use Tupersan (spelling?) with new seeding, if you can find it. Then once Grass comes out and you cut it a few times put down Dimension if crabgrass isn't full blown by then.

    Ditto. Tupersan or Siduron at seeding, usually they have a starter fert with them, and then in 30 to 35 days hit it with Dimension. Oh yeah, prepare to BEND OVER when you see the price... Usually about $40 a bag for 5,000 sq. ft. Scotts and Hi Yeild are the only 2 brands I really know of

    Seeding in the spring is REALLY not the best thing to do. I laugh at all the joe homeowner types that get out there in the spring and tear up the ground and seed only to have the biggest weed and crabgrass patch on the block come july.

    Don't get me wrong, it CAN be done, it's just more expensive to do it in the spring due to the weed competition. Where you are, not sure of your "zone" off hand, but it may or may not be as bad as it is here with the crabgrass. Here it's the state plant (ok, it should be) I had a few non-irrigated lawns, weed patches if you will, that I was gonna throw down pre emergent on, whelp the crabgrass has germinated ALREADY!!! This is gonna be a BAD year...
