When picking seed potatoes, for optimizing your yield in the potato towers, choose a late season variety. These continue to produce tubers off the stem of the plant as it grows, as opposed to just setting one time at the base of the plant. These varieties include Yellow Finn, Red Pontiac and fingerlings. Potatoes like a sandy soil mixture, and a lot of sun. Plant your seed potatoes in a Dr.Grimme’s Tater Tower® planter box. As the plants grow, continue to add soil mixture around the stem of the plant, leaving an inch or two of green plant showing. Add another level to the tower as needed to hold the soil mixture. Repeat, as the plant grows. The more stem, the more places the plant has to grow potatoes! The plant will grow out of the top of the tower. Water as necessary. The potato plant will flower, and then die. HARVEST TIME!
