How to grow

Plant in full sun in well-drained, organically rich soil after the soil warms to 70-85 F, sowing 1" deep and thinning to 8" apart. Grow in blocks of several short rows rather than a single long row to aid pollination. Water consistently and mulch to retain moisture. Harvest when kernels have fully matured and dried on the cob, then save seed to replant.
