Sweet corn is a warm-season annual that is commonly planted instantly throughout the garden. It can be started early indoors in individual packing containers in very short-season spaces.
Sow early sorts throughout the garden 2 weeks after the remaining frost. Sow mid- and late-season sorts 2 weeks later. The soil must be a minimum of 50°F for good germinations. Seeds planted too early would possibly rot. Seeds germinate in 7 to 10 days.
Get began seeds indoors in short-season spaces 4 weeks quicker than setting out. Corn does no longer transplant merely. Be careful not to disrobe the roots, otherwise, growth may also be checked.
For a continuing harvest, plant early-, mid-, and late-season sorts together throughout the garden. Make successive sowings each 3 to 4 weeks up to 3 months quicker than the main expected fall frost.
Broaden corn in loose, well-drained, humus-rich soil. Corn is a heavy feeder and needs most sensible amounts of nitrogen and phosphorus and cheap amounts of potassium. Corn is shallow rooted so mulch to maintain soil moisture and keep down weeds.
Corn Harvest
Corn is ready for harvest when kernels are plump and stuffed with milky liquid. The silks must be brown and in reality really feel damp to the touch. To test corn for harvest, pull one of the vital leaves in part down the ear and press a fingernail proper right into a kernel; if milk spurts out, the ear is ripe.
