|'Seneca Tomahawk' is generally ready for harvest in 70 days. This is an early bicolor which grows especially well in the Northwest. Plants are 5.5 feet tall and produce 7.5 inch sugar enhanced (SE/se) ears with 14 to 16 rows of kernels. Originally domesticated by Mesoamericans, it is a staple food with many other traditional uses. Home gardeners love to grow corn, and there are many varieties suited to different climates. Plant seeds 1 inch deep in rows or clumps, two weeks after the last frost date. Corn needs rich soil, full sun and adequate moisture to produce good ears. It is wind pollinated, so if you want to save seed, you will need to either stagger the planting time of different varieties, or plant them 1/4 mile apart. Water deeply.
