Highs will be in the mid to upper 70’s starting Friday of this week for at least the next 2 weeks.

Is it time this weekend to put it down?

Ideal time is when you're soil temps are between 45 and 50 degrees. We're about on that now.

I do a split application in spring, when soil temps (5 day avg) are 55 then again at 70 degrees.

Is Lesco Stonewall or Dimension better as a pre-emergent granule?

Put mine down tuesday before the rain that night so I didn't have to water it in myself.

Both are good but Dimension does have some post-emergent control on very young crabgrass seedlings if by chance you have a crabgrass issue and you happen to be a little late applying your pre-emergent.

Would you skip pre emergent right now on bermuda that was laid last April?

I already messed up and put down prodiamine in the fall by accident. Wasn't thinking. Currently no winter weeds though!

No, I would apply the pre-emergent. Approaching a year since the sod was laid.

I'm going to do a pre-m application this weekend, but wondering what a good post-emergent would be for burweed in bermuda.

MSM Turf?

That's what I use. A good portion of my lawn is still st aug so that's the only product I've used that kills the burrweed and doesn't make my yard look like shite for 5 weeks

Yes, or Fertilome Weed Free Zone, Celsius, Trimec, Winter Weed Cocktail (Atrazine + Weed Free Zone mixture). Treat it soon while its still immature and before it forms seeds (stickers)
