Anyone read any reports or studies on whether aerations break the barrier of premergents? Can you posts links?

What about dethatching or power raking?

My experience is that power edging ruins the crabgrass barriar along the concrete edge.

Here's something to get you started.

Aeration does NOT affect the preemergent barrier, despite popular opinion, most likely because the actual aeration holes only cover a small percentage of the actual ground cover itself.

Another point along those lines....anytime you're dealing with compacted turf (except for when it is dormant and the ground is frozen), you're always better off aerating. Remember, some annual weeds such as goosegrass (commonly confused with crabgrass) actually thrive in compacted soils. Properly aerated soils contibute to healthy turf, hence, less opportunity for crabgrass or any other weeds to creep their way in. The bottom line is don't wait until the summer/fall to get done what needs to be done right away.

Been numerous studies done on this....general aerification doesn't break the barrier
