I would have sprayed the weed killer before breaking up the soil and then waited a couple of weeks to till it. Now I would just till it all in and do weeding when they pop up.
Looks like a nice sized garden plot. How big is it?
The whole dug up area is about 35 feet by 90 feet. I don’t think I will use the whole area this year, but next year watch out. I still have to come up with a method to keep the raccoons out, not sure what the plan is yet.
