I have shunned all pre emergence

Last season I applied no pre m and then applied a broadcast liquid app of post emergent in May.

I have found that with just two aerations, dethatchings, and fertilizations per year I can make the bluegrass choke out all the weeds.

If you put down pre m the rhizomes of the bluegrass are killed off.
