i know a few years ago sweeney used seed from "seed research" which is quality seed..
there fert was uhs at that time and was good.
sweeney was the first company that gave me a line of credit.
they moved out of my area and if they were back in i would deal with them(if there products were still the same quality)
Theres a Sweeny Seed store a few miles from my home. I think that there are a handful of these stores on the east coast. The prior owners of my house re-seeded the lawn using seed from Sweeny Seed. According to the tag on the grass seed, it seems to be a high quality. The store is sort of a "Lesco" for honeowners.
