o.k - this year i failed in growing corn - we planted the right time [ we think ] - was told i needed NITROGEN [ didn`t have it ] - corn was full grown at 2 1/2 ft. all the stalks were done corn looked terrible - now comes next year - i live in N.C. zone 8 does anyone know what day or month is best to plant - it is a 4x8 raised bed - how much nitrogen ? and how close to put seed`s - A BIG THANKS if somebody can come back with all that
