Sow the corn seeds 1 to 2 inches deep. Space the seeds to 12 inches apart in a row, with the rows set 24 inches apart. Water the bed until the top 6 inches of soil are moist, then continue to water as needed so the soil doesn’t dry out during the germination period. Corn usually sprouts within seven to 14 days.
How is corn grown?
As it grows, corn develops a
thick, fibrous stalk and many flat, pointed leaves
. The stalk can grow as tall as 15 feet, depending on the climate and variety. The roots of each plant grow down 3 to 5 feet and extend about 1 foot or so to each side of the stalk. Some of the roots develop above the ground.
How do you grow corn from seed?
- Start with fresh corn seeds for the best results.
- Directly sow seeds approximately 1.5 to 2 inches deep and 4 to 6 inches apart.
- Cover with soil, space your rows of seeds 30 to 36 inches apart.
- Water your block of corn well after planting.
- Corn stalks are sturdy and should not need staking.
What are the growth stages of corn?
There are 4 distinct stages of growing corn:
planting, germination, vegetative, and reproductive
.
Should corn seed be soaked before planting?
Sweet corn seeds can appear shrunken and shriveled; before they can germinate, they must slowly plump up with water. To help them along,
soak dry seeds in water at room temperature overnight before planting
.
What month do you plant corn?
Corn is a tender, warm-season annual that is best planted after the soil temperature reaches 60°F (16°C), usually
2 or 3 weeks after the last frost in spring
.
How long does it take corn to harvest?

approximately 20 days after the silks appear
. To harvest, pull the cob down and twist it off the stalk.
Why does corn have side shoots?
Corn tillers are also sometimes called suckers because of the old wives tale that they “suck” nutrients from the plant. … Tillers on corn are generally a sign
that the corn is growing in favorable conditions
. However, tillers sometimes develop after an injury to the main stalk early in the growing season.
Can you plant corn without soaking?

Should I soak sweet corn seeds?
Sweet corn does not germinate well in cold soil and in low temperature will die. Sweet corn seeds can appear shrunken and shriveled; before they can germinate, they must slowly plump up with water. To help them along,

What happens if you plant corn too early?
It is not uncommon for emergence to take from two to three weeks after planting to occur, rather than a more desirable five to seven days. Uneven soil temperatures within the seed zone may result in
uneven germination and emergence
, causing potential yield losses of eight to ten percent.
What happens if you plant corn too close together?
Poor air circulation can lead to an increase of
fungal diseases
, such as powdery mildew, in an overcrowded garden. Pests, including aphids and mites, can also more easily move between plants if they are spaced so closely that they touch.
