Jerusalem Artichokes will grow throughout most of the U.S. from Zone 3 to Zone 9. The 6'-9' plants are related to sunflowers. Growing Artichokes is easy: as soon as possible after the tubers are received cut or break each one into sections with one or two eyes. Plant 4" deep 12"-18" apart in rows 3 feet apart. Do not allow the seed pieces to dry out prior to planting. Almost any soil will do whether wet or dry. The plants do need full sun and can stand moderate drought. It is imperative that you harvest the tubers annually or they will become crowded and tuber size will decrease. These plants are perennials so site them accordingly as they your beds will bear reliably year after year. After the first planting you will not ever have to plant again unless you want to increase your yields because the few tubers you miss at harvest will replace the ones you harvested and make next years crop. We have never experienced any pest or disease problems with our test plots (unless you call deer pests) so they are perfect for organic growers. Price includes shipping!
