Yesterday, my two brothers and I planted about an acre of rye grass by hand. It was pretty fun and only took about an hour and a half. We walked in a line and spread out the seed by hand, sprinkling it as evenly as possible. After the seeding was done, we took a piece of chainlink fence, and folded part of it on itself, making it heavier at the end for dragging on the ground. Dragging the fence spreads any uneven seed out and helps bury it a bit. Now we just wait for rain and growth!
