Hi. Turning part of your lawn should be possible, assuming it receives at least part sun (4-6 hours of direct sunlight per day), as most meadow plants prefer full to partial sun. Your best option for a relatively large area like that would be to seed it with native species that have evolved to survive (and thrive) in the conditions in northeast Ohio like those you describe. Typically a seed packet will include many species (perhaps two dozen) that prefer similar conditions (ranging from full sun in dry conditions to partial sun in wetter conditions). The main work involved is getting rid of the lawn grass and weeds that are currently there, which need to be killed before seeding if you want the native seed to germinate and do well. This can be done in a variety of ways including smothering them, doing controlled burns, or using non-elective herbicides. This PDF from the U. of New Hampshire does a great job of explaining the process of establishing a wildflower meadow from seed. I’d also recommend this article from Piedmont Master Gardeners (U. of Virginia), which discusses meadows vs. prairies. Ohio was originally covered by both forest (including meadows) and prairie. Therefore, you will find Ohio seed mixes for both meadows and prairies. Since the eastern half of the state was originally covered by forest (including Stark Co.), you should go with a meadow seed mix rather than prairie. If you search for “Ohio native seed mix” on the internet, you can find some providers. For example, the Franklin County Soil and Water Conservation District collaborated with Prairie Moon Nursery to sell native seed mixes, and Cuyahoga County SWCD collaborated with OPN (formerly Ohio Prairie Nursery) for their sale. You can buy bulk seed to cover the area you intend to seed. If you have any questions about the process, you can certainly follow up by replying to this email. If you decide to use an herbicide to clear your area, be sure to read and follow the label directions carefully. Additionally, here is an excellent fact sheet from Ohio State U. on natural organic lawn care, which should help with maintenance of other areas of your yard.
