Students harvested the first sweet potato crop since the Rural Studio’s farm reboot in 2019.
But unlike previous sweet potato crops, these were grown in the greenhouse. The Farm’s passive solar greenhouse gets so hot and still during the long Alabama summers that it can be difficult to grow many crops in the peak of summer, and sweet potatoes take up so much space that they are difficult to grow in our small, intensively managed outdoor cultivated areas. Growing the potatoes this way solved both difficulties at once!
Sweet potatoes are most often grown from slips, which are small shoots cut from mature sweet potato tubers and rooted. The farm team planted 200 sweet potato slips into the raised beds in the greenhouse on June 7.
In only a matter of weeks the vines from the growing slips swallowed up the greenhouse: filling the aisles, climbing the barrel wall, and bursting through the windows. It was a beautiful transformation of the space that required almost no maintenance all summer long.
After four months, students dug up the new tubers and cleared out all of the vines.
Once dug up, the tubers then needed to be placed in a warm, humid environment in which to cure for about two weeks. During the curing process, the sweet potatoes’ skin thickens somewhat, any wounds or nicks heal over, and the sweet flavor of the flesh concentrates. Not only does this improve the flavor, but it significantly lengthens their storage potential, so students and staff can enjoy sweet potatoes all throughout the winter.
