Growing Info
Harvesting: Sweet corn is ready about 3 weeks after the silks appear. Harvest when the silks are brown, but not dried, and the husks are dark green; ears should be plump, and rounded rather than pointed at the tip. To test for ripeness, gently pull back the husk and pop a kernel; the liquid should be whitish; if it is still clear, ears are not quite ready.
Special Care: Keep area weeded, especially when plants are young and have shallow roots. To guarantee good pollination, gently shake the tassels to release the pollen onto the silks. You can also hand pollinate by pulling off a tassel from one plant and wiping it on the silks of several ears. If you notice "skips" or blank spaces on an ear where a kernel should be, that is an indication of inadequate pollination.
