    if a pre-emergence [chemical] was used for crabgrass can a compost tea be applied or will the microbes be destroyed on the way into the soil????

    It will depend on the chemical used. I would like to point out that if you are using a pre-emergent, you should probably let the chemical do its thing before you apply any CT.

    Atrazine , weed and feed, is PURE poison to the earth and dangerous to kids, hire a labor and use a weed weasel.
    organic pgrs are not that un common in nature, rosemary,Spanish moss,CMG,most seed meals,some types of fungus,and a lack of water and sun are sure fire ways to keep the weeds gone. we have water Restrictions 1 day per week. try and get anything to sprout with one watering per week, it had better have a root system or it is a goner.
    the dollar weed cant ever get off first base.tall grass "4 inches " will shade out there ground space and a seed will usually not germinate until it gets some sun/heat.are we talking about a weed that has a meristem on top that gets whacked of as soon as it gets past the 4 inch mark. or a seed reproducer that never get to make a seed again because its head was whacked off.what is the target and the need to kill it off. some of my more tolerant customers have allowed us to plant clover in there "SOD" and now say its just gorgeous. in the 1940s grass seed came with clover added to the grass seed. why did we stop doing this ?

    Ok that's not the rite thing, try Cinnamon oil, or re think the killing part. maybe you should just make the lawn strong so it will out compete the crab grass and weeds.
