A few things I've learned about garden corn over the years:
1) Soil prep begins well before any seed corn is planted. I use legume cover crops in the preceding summer and legumes and small grains cover in the preceding winter...and never plant corn in the same location for at least two growing seasons. Doing this takes care of my fertilizing needs along with fish emulsion applied during growing
2) it is very important to plant your seeds all in the same direction and same depth to help insure perfect simultaneous seed germination which in turn insures pollination which is critical to success. Plants germinating late won't pollinate properly...you want them all tasseling at the same time.
3) Corn needs several facing rows to pollinate fully. This is critical.
4) Growing is easy but I advise stagger planting to provide a continuous supply of fresh corn all summer and fall. I have two plantings going right now, one started April 1 and a second started May 1. I will do a third planting on June 1 and should have continuous fresh corn after that until frost.
Garden sweet corn is one of the ultimate taste delights one can experience. We absolutely love it!
