You can spot kill the grass with a foam paint brush and a non specific herbicide but the problem
is that you already have lots of grass weed seeds down in the seed bank aka the soil. Your best
bet is kill the whole area off by an herbicide or plastic and start over next May or June. You want
that weed and grass seed to germinate if possible and kill it off in 2026. If you have some good
wildflower seed heads in your project go ahead and pick it now and put them into a paper bag and
store it in an unheated space to use next year.

If you just want to till the area keep it tilled until late August. You can plant some of the seeds in pots
and plant them in the fall of ‘26.

Make sure your wildflower plot has a next mix of grasses … I like VA wild rye & Canada wild rye,
native flowers that bloom from spring until fall, and some legumes. It takes time.
