not too late, prodiamine is a good one, it's generic Barricade (much cheaper)

Not too late, as mentioned Prodiamine or Dimension; cracks - common in unvegetated dry, heavy clay soils - clay physics - but we’ve had rain so I’m not sure.

If you’ve had an issue with crabgrass in the past, Dimension has post-emergent activity on seedling crabgrass that Prodiamine doesn’t provide so you can take that into consideration in your choice. If you are new to this, remember the pre-emergent needs to be watered in by Mother Nature or you to be activated - that info will be on the product label.

My yard is already full of weeds. Are you saying it’s not too late for preemergent? I’d imagine it’s too late for me since weeds are already all over. I really need to get my yard under control this year.

As poochie stated, not all weed seeds germinate simultaneously, applying pre-emergent now will help to control many, not all, weeds whose seeds germinate at soil temperatures of 60, 65, 70F….over the next few months. Control the weeds you have now with post-emergent herbicide.

It will prevent new seeds from emerging so don’t spray there.

ETA: you should maybe look at this as a 2 year process. Focus this year on getting good grass growing. Use post emergents to keep the weeds in check and get the good stuff growing then really hone in once you have that working.

Site One has it. So does Cleggs.
