Is it too late to spray for dandelions?

Weeds need to be actively growing for the weed killer to work. The
colder it is, the less effective the herbicide will be.

For where you are, I think it's too late, by about a month, maybe two.

Save the weed killer for the spring.

I put on pre-emergent herbicide in the spring and a broadleaf weedkiller in
early summer. That works against crabgrass and dandelions, the two biggest
problems in my lawn.
