Solanum tuberosum

Fruits and Vegetables

Seed is unlikely to produce good tubers, but may be started in early spring, optimal temperature 68F/20C, or started inside earlier on much like their tomato cousins. Reproduce any good-sized tubers, the next year. Note that purchased tubers, sometimes referred to as "seed", should always be certified virus free

Plant tubers 3 weeks before last frost. If 2" in diameter, plant whole, if much larger, cut cleanly into sections with 2-3 eyes each, and allow to callus for several days. Set 6" deep, as many eyes as possible facing upward, and cover with 2" soil. Space 2-3' apart, depending on cultivar. As plants grow, fill in gradually with loose soil; mound up around stem several inches after hole finally filled. This cool-season crop requires a longer growing season and will not tolerate any frost. Prefers acidic soil, good amount water
