The wife has been buying Indian corn at the local grocery in hopes of using it as seed next spring. Can this be used or is corn bought at a grocery unusable?
I don't see why not. The stuff here is grown on local farms and delivered to the store. It is not like it has been sitting around. Unlike many seeds, corn has a short storage life and needs to be sown the following year. Your wife does know the Indian corn is not for fresh easting.
Yeah she just wants it to grow to decorate and give to friends thanks again.
