What is best fertilizer for sweet corn?

Use 2 to 3 pounds of fertilizer, such as 10-10-10, for every 100 square feet of garden area. Spread the fertilizer evenly over the soil and work it into the soil 3 to 4 inches deep. Rake the soil to smooth the surface.

What happens if you plant corn too early?

The earlier seeds go into the ground, the more likely they will face stresses. Cold, wet conditions can make corn emergence difficult, causing yield loss. Delayed emergence also lengthens the time that seeds and seedlings are most vulnerable to early-season insects and diseases.

How long do you soak corn seeds before planting?

When soaking corn seeds, use lukewarm water, about 68 F, and if you’re planting more than one variety of corn, soak them in separate labeled containers. Recommended soaking times range from a few hours to up to 24 hours, with no more than eight hours being the usual.

Can you plant corn close together?

A rule of thumb for planting corn is to space the rows approximately 36 inches apart and space the plants within each row approximately 12 inches apart. … Instead of planting single rows that are equidistant from each other, plant blocks of double rows.

How do you speed up corn germination?

One easy way to make seeds germinate faster is to presoak them for 24 hours in a shallow container filled with hot tap water. Water will penetrate the seed coat and cause the embryos inside to plump up. Don’t soak them for longer than 24 hours because they could rot. Plant the seeds immediately in moist soil.

Is it too late to plant corn in Tennessee?

Plant corn as early as practical for best results, typical- ly before May 1 in West and Middle Tennessee and before June 1 in East Tennessee.

How long does it take corn to sprout from seed?

At 50° F corn will take approximately 25 days to emerge. At 55-60° F corn will take 10-14 days to emerge. At 65-70° F corn only takes five to eight days to emerge (Meyer). How long a seed can last in the soil and remain viable depends on temperature, moisture, and pests.
