Visit The Mill of Black Horse

The Mill expanded to serve you in your town.

After more than 20 years as a Southern States Company-owned store, The Mill of Black Horse officially became a member of The Mill family in January of 2003. It has long been a fixture of the agricultural community and now it’s the hub for our fencing supplies, agronomic services, including custom fertilizer and chemical application.

This location hosts an annual “Black Horse 4-H Day” in May, which is well attended by community members. The 4-H members sell pit beef and other lunch items as a fundraiser to help their club.
