Farmer Vicki/Genesis Growers will have her greenhouse purring by March. She's based in NW Illinois.
I gotta imagine that City Farms on Clyborn will be growing chard and such as soon as the ground is soft enough.
There are meat packers and live chicken places in Chicago and obviously a fair amount of manufacturs like Tootsie Roll, Bloomers, Mars, etc. There have been other threads on Chicago products.
What exactly do you want, locally grown food generally, locally grown food in March or locally manufactured food?
