Corn demands fertile soil, consistent moisture and warm weather. If you have those and plenty of garden space to spare, it’s not hard to grow great-tasting corn, and you won’t get it any fresher.

Growing Guide
GROWING NOTES
Needs deep, well-drained, fertile soil, pH 6.0 to 6.8 and consistent, plentiful moisture.

Tender annual Requires excellent soil and consistent moisture.

Otherwise, it's not difficult to grow.

MAINTAINING
Corn requires rich, fertile soil. Add compost or well rotted manure in fall. Consider planting a legume cover crop the season before corn to help meet the nutrient needs of this heavy feeder.

Make first planting after last frost date. Soil should be at least 65 F for fast germination. (Corn will not germinate if soil temperature is less than 55 F.) To speed increase in soil temperature, consider covering soil with black plastic for several weeks before planting.

Plant in blocks of at least 4 rows of a single hybrid (as opposed to fewer, longer rows) for good pollination and well-filled ears. (Some corn varieties need to be isolated from others. See variety information below.)

Plant seeds 1 inch deep and 4 to 6 inches apart in rows 30 to 36 inches apart. Thin to 8- to 12-inch spacings when plants are 3 to 4 inches tall. Increase seeding rates to ensure a good stand if soils are cold or you are using seed that has not been treated with fungicide. (Untreated seed has natural color. Treated seed is dyed.)

For a sequential harvest, make first planting using an early hybrid. Two weeks later, plant another block of an early hybrid, plus blocks of mid- and late-season hybrids. Continue making plantings until late June or early July, depending on the length of your growing season.

To save space, you can intercrop corn with early-harvested cool-season crops.

Corn plants have many roots close to the surface, so cultivate around them with care. You can hill soil up around the base of plants as they grow to bury small weeds in the row and give the corn a better foothold. After the soil has warmed, you can mulch corn to help suppress weeds and retain moisture.

It is not necessary to remove suckers (side sprouts growing from the base of the plant). Studies show that removing them may actually reduce yields.

Corn is a heavy feeder - particularly of nitrogen - and may require several sidedressings of fertilizer for best yields. Look for signs of nutrient deficiency. Purple-tinged leaves are a sign of phosphorus deficiency. Pale green leaves are a sign of nitrogen deficiency.

For miniature or baby corn, plant seeds 2 to 4 inches apart and harvest as silks emerge from the ear, or harvest secondary ears from normally spaced plantings, allowing the main ear to fully mature. Also try hybrids specifically bred for early baby corn harvest.
