It's easy to grow red- and white-skinned Irish potatoes and brown-skinned russet potatoes. Good Irish potatoes for Florida include 'Yukon Gold' and 'Red Pontiac'. A good russet is 'Norkotah'.
Look for "seed potatoes" at a feed store or online. Avoid grocery store potatoes, since they’re treated to prevent sprouting. Cut your seed potatoes, leaving at least one eye per section, and let them dry for a few days.
Plant potatoes in January, February, or March in North and Central Florida. In South Florida, plant them from September to January. Plant the sections in a six-inch deep trench in a spot that receives full sun.
Water and fertilize on a regular basis, and mound soil around the stems as the plants grow. In about three months, you’ll be able to enjoy delicious homegrown potatoes.
