Now after two decades employed by others, he’s among a group of 10 farmworkers looking to carve out a new path in agriculture. On Sunday morning, Mr. Flores of East Quogue and fellow members of the Long Island Farmworker Cooperative could be seen setting up plants outside their new weekly flower market on Roanoke Avenue in Riverhead. The events are a chance for the group to branch out on their own.
