only half-dead weeds

[barbie gee]

I sprayed some weeds in the front yard last week with "broadleaf weed killer". They are now wilty, but not dead.

What to do now?

I'm generally one not to use weed killers, but this patch of yard is so dense with weeds that I simply threw up my hands and said, "kill them now". I mixed from concentrate, and got the rate right, but wonder if maybe the concentrate is "stale", since it's a year or two old now??

so, respray with fresh killer? wait another week and see if the weeds finally go brown and die? what?

Let them finish dying on their own.

What is the brand name of this weed killer? What is the active chemical in this weed killer? Some broadleaf killers can take up to 4 weeks to finish off the weed. I would highly doubt that your weed killer went "stale", but it is possible. Some chemicals break down with air exposure.

Depending on what the weeds were, you might have been better off just pulling them by hand. Dandelions aren't quite as pernicious as the herbicide companies would want you to believe. (This may not be true in FL, CA or TX).

It might be too late now, but for future reference, if they have any seeds heads, I would cut them off and throw them in the garbage.
