Anyone been successful in overseeding low-mow fescue to replace lawn?
I don't believe we're allowed to use our planned idea of cardboard because of the septic system.
We wanted to replace the existing lawn with "Let it Bee" no/low mow (https://ptlawnseed.com/collections/no-mow/products/pt-702-let-it-bee-a-no-mow?variant=43998137155802) which is a fescue mix + clover, and also a low profile wildflower mix in some sections.
I've seen suggestions of just overseeding with the fescue mix but I'd love to hear if anyone has had success getting rid of standard lawn that way, or if it's just too hard to get rid of it without actually killing it off.
Would raking it before overseeding, or putting down 1/2" of topsoil before seeding help? I think we can do the topsoil without it being an issue. Or should we just hire someone to do plug aeration and seed in the fall?
Trying to decide if this is a fool's errand and we should just pony up for the riding mower.
