Oh, get ..
out .. of my head, Brother, you scarin' me. :shocked: (.. I've written and deleted both comments, in so many words. :laughing
What Roy King says. ^^ :thumbsup: and word for word. First-year crops to turn under and build up soil include alfalfa, buckwheat, cow peas, any clover ... Mow any of them 'close'* enough they'll look like 'lawn', (*4" setting on MM/ZTR deck vs 6" w/BH) and their eventual health (2-3 yrs) will tell you when it's time to over-seed with your final choice. Until then, biomass, biomass, biomass ... and I mean all mentioned so far. (!) Ph checks by the third year.
IMO, by far the biggest impediments to a 'nice lawn' are 'blanket' vs 'spot' weed spraying,
lack of patience when developing healthy turf (got 2 yrs?), and
#1 setting cutting height more than one notch below the highest setting possible. I mow my second house's lawn in the 'transport' position with the '13 Husky MZ6128 or '96 Dixon 4221. Whatever I
don't do, "lawn happens".
