Sweet Corn (Zea mays)

Sweet corn likes a ph neutral, reach soils in the full sunlight. You can start planting when the soil temperature reaches 50-60 F, for me it is May 15.

On the small scale, you can plant couple of seeds, about 1.5 inch deep, in a row about 12 inch apart, since the corn is air pollinated, multiple rows will benefit the plants positioned on the edge, so plan to plant square, or rounded plots.

Since you are planting couple of seeds per spot you will have to select the healthiest plant and snip others, this of course would not pay on the large scale.

Corn has shallow roots, so it needs moist top soil.

You can plant pumpkin/squash and green beans next to each corn plant, they will use it as trellis. Green beens will fix atmospheric nitrogen in the soil, for the NEXT YEAR cultivation, after they decompose.
