The fescue seed have been down in a minute for 3 weeks.

It has come up and have already been mown once or twice in a minute.

I want to spray for the broad leaf weed now within the lawn next to Ortho weed b gone Max concentrate.

Will it be okay?

How much longer should i wait, save?

I am afraid if I wait too long here within Tennessee that it will be too cool at the end of this month for it to work. Last week we have temperatures up surrounded by the upper 80's and lows in the 60's, but this week it will bring back down to the mid 70's for highs, and low 50's for lows.


Thanks for your answers!

Answers:    Best not follow foo's guidance, if you use Round-up it will kill everything including the grass!!!!

Its probably too soon to spray your grass, most manufactures of selective herbicides recommend 4-6 weeks since you spray. So best wait a few more weeks or until spring. I don't know which chemicals are available within the States but here in the UK the following chemicals are available;

>2,4-D
>Mecoprop-P
>Dicamba (probably too strong for a fresh lawn)
>fluroxypyr
>clopyralid
>MCPA

These names nominated are the active ingredients, and not the trade name, trade names may include Bio-lawn and Verdone.

Best of luck, but what ever you do don't use Round-up!!

You'd be best to use Glyphosate - probably Roundup as its the most established capably know. Its the perfect time of year to use it and it breaks up on contact near soil so its safe to use.
