I'm always too late for pre-emergent so this year I'm trying harder.
New York City, mostly concerned with dandelions, crabgrass, and
clover. Since I let my cats into the yard, I'd like to put something
down that will not harm them. I figure I can keep them inside for a
week or so to give the poison time to dissipate. Does it work like
that? If not, I guess I'm stuck with the weeds. Thanks.

Pre-emergent herbicide is a must for crabgrass but is not a must for
other weeds. Other weeds can be controlled without precise timing.
The timing for using pre-emergent herbicide for crabgrass is best
indicated by the Forsythia's bloom withering.
I would think that the date would be around the first week in April.

Ah, so I need to do this two weeks before the daffodils bloom withers.
I don't know of Forsythia near my house but since 9/11 some Dutch
company has been flooding NYC with free daffodil bulbs so the whole
area has daffodils planted. I noticed last week that they were coming
up.
So another few weeks and I get to nail the crabgrass at least. That
will take out about half my lawn I guess. I really lost the battle
last year.I'll be seeding quite a bit.

If it's alive now, it's not crabgrass.

FYI, you can't seed right after most pre-emergent crabgrass herbicide
applications. There are products you can use while seeding, but I don't
know how effective they are.

you can use corn gluten meal for a preemergent, shouldn't bother cats
any.
