    Well it's that time again in the Northeast....Application time. Over the years I've heard just about every story and tale about when it is best to apply Crabgrass prevention. I've heard everything from, When the ground temperature is 60 degrees to when the Azaleas bloom.

    Now that I'm on this great website, I thought I'd ask everyone, What's your take on application...? ;)

    Good rule of thumb is just as forsythia starts to bloom. Azaleas? Try weed n feed by then.

    Crabgrass germinates when soil temps average 55 degrees for a few days.

    We just hit that range in North Georgia a few days ago.

    You folks up North still have some time, but never too early to get it done.

    Great advice Turf Unlimited. If you can Lost Pine, try to do split applications of 0.25% a.i. per acre.
