RE: Throw & Grow
the best stuff i have used so far is LabLab. do like you mentioned, get a hand tiller and till up a spot. broadcast the LabLab seed throughout your tilled area and use a rake to lightly cover the seeds. then spread some fertilizer, i used Red Fox 12-12-12 which worked like a charm. i didn't bother with liming and measuring the soils pH due to the LabLab being very tolerant of acid soils. within a month all of my plots were green and flourishing.
