What? Come on Kanter, they might just do that. LOL.. Crabgrass loves compacted soil. Plug aerate the crap out of it with 4" plugs at least in the fall before re-seeding. Use ONLY the recomended setting to apply any chemical on your lawn. Pelletized lime also (but in like mid December and 1st week of August) so your lawn can take up the nutrients and not leech anywhere. Its not rocket science, just timing and conditions (sloping compacted soil, drought, too hot, etc) Your seed in the yard probably wont germinate anyway. The seed is only good for 9 mos. in the bag in Va. and can only be tested twice and then deemed no good, soooo, if the bag you bought was already re-tested, then chances are....(you can tell if re-tested by the "stick-on" label on the original test date). Take a trip over to Solomans Island and visit the Univ of Maryland Center for Environmental Sciences Chesapeak Biological Lab to see where "everyone elses" chemicals go. They're pretty cool folks there. KC in Richmond Member--Virginia Lakes and Watershed Management Asoc. Oh yea, the bays not dead, just biding its time to get even with that asteroid.
