Is it too early? Been kinda warm lately and would rather be early than just a bit too late… soil temps seem to be increasing a little faster than is typical for this time of year.

Apply pre-emergent herbicide Dimension, Halts, or Balan to prevent germination of crabgrass and grassburs. March 1-15 in Central and North Central Texas. March 20-30 for North Texas/Panhandle. (See related story this issue.)
In Plano, the forecast doesn't show it dipping below 40F for the next 2 weeks. I'm hoping we have seen our last freeze.Quote:
Neil Sperry recommends "2 to 3 weeks before the average date of the last killing freeze for your area".

You need post emergent for any weeds that you are seeing now. Dandelions are broadleaf weeds. As long as you don't have St Augustine grass, you can find a post emergent that has 2,4D in it and take care of those.
ac04 said:the weeds you're seeing now would have been prevented by pre-emergent applied last fall. an application now (and another in may) would be to prevent weeds this summer. you're not too late for that.planoaggie123 said:
So I missed the window for pre-emergent i think and starting to see weeds in our part of lawn with Bermuda (the rest of our lawn is newly laid Zoysia so have to leave it alone).
i would probably apply pre-emergent today and post-emergent to kill the existing weeds this weekend. i think technically you can do both at the same time, but i prefer to split them up.
