Messed up need the experts advice

[Joshfcb1]

Long time viewer of the site but didn’t post much at all and account was deactivated.

Anyway worked well past dark doing a small Reno on a portion of my tttf lawn. In a rush I hastily grabbed “weed and feed” and didn’t realize until it was too late.

Do I have any recourse to save this?

Expert is a subjective term here. But I’ll answer your question with a couple of my own.

Did you apply it at same time as when you put the seed down or after?

Did the weed and feed contain a pre-emergent herbicide?

[Joshfcb1]

Lightly tilled the area, applied seed, applied fertilizer, then harrowed. Intended to straw this afternoon and begin watering until I saw my mistake.

[turf_toes]

Yeah. But you didn’t answer my questions

Well, it answered one by implication, maybe. There's no pre-emergent in there. Working under the assumption (please see the old joke about assuming) that fertilizer was actually weed and feed, then there's one recommendation here:

Water very, very deeply, several times, to flush the herbicides way under the soil surface and away from the seed as fast as possible. You don't want them at the soil surface where they can impact the sprouting seed, which will have some sensitivity to them for the first few weeks. I'd recommend 2-3 inches of water applied such that it soaks in, done on two successive days. And make sure to keep the top damp regardless between the waterings, because it will dry out a bit.

After that, just damp the top three times a day. The herbicides will be flushed out and so will the feed part...there's nothing you can do about that, but didn't need the feed to start seed off anyway.

Thanks for the replies. Your advice lines up with what I was told locally as well.
