i got this seed called quick stand no till forage from plotspike seed. its tetraploid rye grass, rape and annual crimmson clover. in pa it says plant aug1 to oct31. pa being the far north of the its zone for nh it say july15 to sep 15. 20 lbs per acre.
now i haven't tried it but its suppose to be really quick growing. for what its worth. i got it for pa but didn't get it out. i think i got it at tractor supply.
oh it still says for best results do the plot thing with tests, lime, and fertilizers. ya know food plot things.
