Page 1 of 1Sweet corn is easy to grow and delicious straight off the stalk, grilled, or boiled. Corn can be white, yellow, bicolor and even red.
4-11 (Find your hardiness zone.)
When to Plant:
Directly sow seeds in mid to late spring. Try planting several varieties with different maturation rates to extend your harvest. Sow seeds in trenches that are 4-6 inches deep and 18 inches apart. Sow the seeds 4 inches apart and thin the plants to space them 12 inches apart.
Corn needs heavily enriched soil that is nitrogen-rich. Soil should be loose with a neutral pH. Corn needs full sun.
The average corn stalk is between 6 and 8 feet tall. To eliminate the need for hand pollinating (see below), plant at least a 10 x 10 foot block of corn.
Corn is pollinated by the wind so you can't plant it in a single row or else the male tassels will never come in contact with the female silks. If you are unable to plant blocks of corn, you will have to hand-pollinate them yourself. Simply remove the male tassels and touch them onto the female silks. Apply a complete organic fish emulsion fertilizer biweekly. Water deeply once a week if rain is inadequate. Raccoons love corn, so you'll need some crafty deterrent methods to keep them away.
When to Harvest:
Corn matures in 65-90 days, depending on the variety. Squeeze the ears to test for appropriate firmness and bulk. The ears will be a rich green color and the tassels will turn brown when they are ready to be picked, which is about 20 days following the emergence of the first silk strands.
A 10 x 10 foot block will yield approximately 50 pounds of corn.
