    Dimension will not allow new grass to grow beyond the germination stage if at all. Just ask my neighbor, I told him not to waste his money on grass seed after he put Dimension down but he did it anyway. Not one single seed germinated.

    You can use TUPERSAN.

    It is somewhat costly, and not very effective. You will have to re-apply a pre-M after mowing the new turf twice. By then I'd suggest Dimension as it may also be used as a post emergent if crabgrass is caught in 1st or 2nd tiller stage.

    You can use Tupersan but I would not. Seed the lawn, let it get established and mowed 4-5 times then deal with weeds and crabgrass as needed.

    Drive 75 allows seeding at time of application but only has a residual of 30 days.
