Corn and Popcorn
Corn and popcorn are warm weather crops. The seeds will germinate more consistently if the soil temperature stays above 65ºF. To get a jump on the season, plant your corn and popcorn inside in flats on May 1st. By the end of the month they are ready to plant outside. To get a staggered corn harvest, at the end of May, you can also directly seed into the garden another 32 seeds of corn. In another 3 weeks, direct seed again. Using an early maturing variety like Ambrosia can get you three harvests over a two month period.
Plant corn in a good rich soil. They should be planted in rows at least 4 ft wide and 4 ft long for good pollination. Harvest sweet corn when the silk turns brown and you can feel well formed kernels under the husks.
Popcorn is another story. This is a long season crop. It needs all the summer it can get. Plant these inside first, then move the seedlings into the garden at the end of May. Remember to leave popcorn on the stalk until the outer husks have turned brown. This is usually the second or third week in September. Bring inside, husks and all and dry for another two to three weeks. Then remove the dried kernels from the cob, store in airtight jars and enjoy through the winter.
