    I figured I knew last time around but maybe I'm missing out on some of the finer more expert details (ie: waiting for or past cold/warm streaks, rain, mowing recs before and after, etc).

    Just a few degrees North of you, and we put down our pre-emerg in February-March and again Oct-Nov.

    Remember pre-emergent herbicides need to be watered in to be activated, so applying before a rain ensures they will get into the soil before they deteriorate.

    Two apps in the spring typically Jan.-April and one app in Oct.-Nov.
