I've failed twice at getting cheap alfalfa seed to take earlier this spring. The light mix of grass seed i mixed in has done well though and I'm keeping a thick plot of grass mowed regularly now through summer. I'm wanting to plant alfalfa and/or a good perrenial mix soon, (late summer/early fall). I live in central Iowa and it's an acre of full sun on a hilltop, so it's well drained. Lots of good Iowa black topsoil. What should I plant? Do I need to kill my grass off completely? I'm wanting low maintenance that will last a few years at least. Something that will be relatively easy to establish. I've sold all of my heavy machinery, so only have a single axle disc that I pull with my truck. I'd like to disc really well, throw down seed, then disc again, if that's even an option. Alfalfa is appealing, because I can bale it if I want to, and it can last several years. Got any advice for seed to plant? When to plant it? Will my planting methodology work? If not, what do I need to do? Thanks in advance.
