Corn Overview

Description Few things say summer like sweet corn, picked just minutes before eating. Sweet corn starts converting its sugars to starch the second you pick it, so it's hard to find sweet corn more tasty than that from your backyard. Sweet corn takes space. It's essential to plant a number of rows (more is better) because the ears are wind pollinated and they need the critical mass for best production. For this reason, it's most efficient to plant corn in a block of short rows or hills rather than in a few long rows. Most stalks produce just one or two ears of corn, so plant plenty! And do what the professionals do: Plant early-, mid-, and late-season varieties to ensure the longest season of harvest, several weeks in late summer. Choose from standard sugary (su), sugar-enhanced (se), and supersweet (sh2) varieties with yellow, white, or bicolor kernels.

Propagation Seed
Harvest Tips When the silks of the ear begin to turn brown at their tips, peel back some of the husk to check for maturity. Kernels at the ideal stage for harvest will be milky. Immature kernels are watery; over mature ones are tough and doughy. With a sharp downward twist, break the shank or stem below the ear without breaking the parent stalk. Cook and eat the ears immediately or prepare them for freezing or canning as soon as possible to retain maximum sweetness.
