Ironite now to take advantage of the free rain water.

Do you have enough weeds to warrant using an herbicide?

Yes lawn if full of weeds. 9 days ago I aerated with spike style tow behind. That's what the rental company had other than a power model. Then I applied Scott's step 1. Haven't mowed sense. Planning to mow in a few more days at a high setting (3.5") and keep it there for the season.

I just applied the Ironite. How soon now can I spray weed b gon?
It's gonna be a balancing act between that and the rain in the forecast. I need to mow soon but don't want to until 1-2 days after weed b gon is down.

I would almost think your best bet is to do ironite before the rain and weed b gon after.

I guess I just know and like Ironite. A big factor is that Amazon prime has it for $18 with free 2 day shipping. Not bad for 120 lbs of product.

I never seen Ironite in 120lb bags. Even if you mean 3- 40lb bags at $6 each, that's a steal. Can you link to that?

$18/ bag (40lb x 3) = 120lbs of product shipped free at my door in 2 days.
