Are some of yall having problem with crabgrass this yr?
Not really... just along the driveways and such... we have shade in most lawns, mow high and irrigate regularily, but never put down pre-m...
I'm seeing it on untreated lawns a lot. I have very little breakthrew. A few tiny spots near sidewalk/street.
In past years I have seen crabgrass on treated lawns after they were power-edged. Edging of course breaks the crabgrass barriar.
What can you do?
I do two pre-emergents and have seen very little brake through this season. On non irrigated lawns I have seen some brake-though along driveways and walk ways as expected. But a mix of Drive and Pre-M knock it out pretty quickly
Only hairy/large crabgrass. Apparently dimension doesn't control (i.e. not on lable). Put down two apps. It was 3" tall when smooth crabgrass was only in its first tiller stage. Didn't believe the extension at first but Drive is knocking it down. Anyone else have this problem?
