I read on your site, as like a few others, about overseeding with St Augustine seed. You state seeding isn't recommended years ago but new methods of seed development has created a way to do it. Where can I buy that seed? I have a Raleigh St Augustine yard that I laid by sod rolls 2 years ago (5000 sq). It looks great but I think a light overseed in fall would be great for early spring growth. I just can't seems to locate the seed. I know to dethatch good, as seed needs to go on soil and to keep moist. Where is the seed found?
