Do you guys do an early summer Pre-em?

I have never and will never do a pre em in the summer. Late fall and late winter and then early spring for me.

I think some do, and I did so for the first time May 1 applying Specticle Flo pre-emergent b/c I’ve had a serious issue with Doveweed in summer, a later germinating summer annual, that Specticle is supposed to be good at controlling (I hope so) - I should know how well it worked in the next 2 or 3 weeks.

But as a general rule a summer pre-emergent shouldn’t be required, a heathy thick fast growing lawn shouldn’t require it. Summer pre-emergents are not recommended by LSU AgCenter weed control specialists except under “unusual” conditions - in my case it was recommended to get on top the Doveweed issue.

Ok. I don't have some crazy problem. I can spot treat with Celsius in the summer. Thanks, y'all !

Same here. All the publications advise to do a round in late spring, but here's the issue with that. If you lay down sod and/or overseed, the pre em actually works against that preventing new growth. And it's good for about 3 months. So the best thing to do is lay it down in February, which gives you Feb, March, Apr for the pre em to do its thing. And most of us overseed and/or lay down new sod starting in May. So that way, the pre em isn't affecting that. Learned that little tip from Doc on YouTube.

I meant most of us as in that's the time to do it, not as in most of us do it.


Sorry, didn't clarify that.
