In this question, I was asking about trying to deal with stubborn grass that won't practically cut with a reel mower. And in this answer, it's mentioned that these kind of grasses just get pushed down with a reel mower, which is pretty much exactly what's happening. This isn't the answer I had hoped for, but probably the answer I need.
I like these rougher field grasses on the periphery of the lawn as they do a good job at providing some habitat and keeping the edges stabilized, but I think because I've been unable to consistently mow them effectively, they're just pushing into the central part of the lawn where the kids play and frankly they're not much fun to step on with bare feet (i.e. sedges have edges).
We would like to push these field grasses back and ideally replace it with something like clover so that it's more suitable for play. Per USDA, we're locating in the 6B hardiness zone though we're very close to 6A as well.
My plan for this is to try and cut the field grasses using a weed wacker, lay down a white clover seed mix, and mulch the area. For reference, the seed mix is likely to be something chosen from our state conservation service's recommended seed mixes (see Table 4-2).
Would this work to push out the field grasses or would I need to try and rip them out manually before re-seeding? Are there other factors I need to be considering?
