How to Sow
- Growing corn is easy provided you have enough space and plenty of sun. Corn is wind-pollinated, so you need to plant in blocks to ensure pollination. You should have a minimum 10 foot by 10 foot area. The exception to this rule is ‘On Deck’ corn, which has been bred to grow in containers. If you are growing ‘On Deck’, choose a container that is at least 24 inches wide and deep and plant nine seeds evenly spaced.
- Isolate corn varieties when recommended (Sh2s), by planting corn seeds at least 250 feet apart, or select varieties that mature at least 2 weeks apart so they will not cross pollinate.
- When choosing a site for corn plant on the north side of your garden so the tall plants do not shade other plants in your vegetable garden.
- Corn is a warm season crop and should not be planted in cool soils. The non Sh2 varieties tend to be more tolerant of cool soils, but in general the soil should be about 65 degrees F or warmer.
- Sow corn seed 1 inch deep, 5 to 6 inches apart in rows 2 to 3 feet apart.
- Seedlings emerge in 7-14 days.
- When corn seedlings are 3-5 inches tall and healthy, thin to 1 foot apart.
How to Grow
- Keep weeds under control during the growing season. Weeds compete with plants for water, space and nutrients, so control them by either cultivating often or use a mulch to prevent their seeds from germinating.
- Keep plants well watered during dry periods to promote uninterrupted growth. Corn needs 1-2 inches of rain per week for best production. Use a rain gauge to check to see if you need to add water. Corn is also a heavy feeder and will benefit from side dressings of fertilizer applied as directed through the growing season.
- Monitor for pests and diseases. Check with your local Cooperative Extension Service for pest controls recommended for your area.
- Suckers tend to form at the base of the plants; they help support the stalks and make food for the plant. The stalks may have to be staked in windy areas, but in general they are self-supporting.
- Sunflowers are good companion plant for corns. Direct sow sunflowers in rows parallel to corn rows to help separate corn varieties that need isolation from each other. Choose sunflower varieties of comparable height to the corn plantings. The sunflower border, with vibrant hues in russets to golden-yellow, will add sparkle next to the almost all-green corn plot. The ‘Three Sisters’ (corn, bean and squash) are traditional companion plantings with Native American gardeners.
Harvest and Preserving Tips
- Ears of corn are ready to harvest about 17-20 days after the silks appear. The kernels should be firm. Open an ear and pierce a kernel with your fingernail. If the liquid is watery, the corn is not ripe yet. It should be milky. If it is creamy, it is overripe and will not taste as sweet.
- Firmly grip the ear and twist downward to harvest. Take care not to break the plant when harvesting the first ear, or the second ear will not develop. Most corn produces two ears.
- Store unhusked corn in the fridge and consume as soon as possible. Sh2 and SE varieties keep the longest in the fridge, up to one week.
- Corn freezes well after blanching and may also be canned using a pressure cooker. Immature ears may be pickled.

Corn, Early Xtra-Sweet Hybrid is rated out of 5 by 5.Rated 5 out of 5 by northwoods from Great germination rate!! Planted Early Xtra-Sweet Hybrid Corn exactly as you recommend ...I planted on June 1st. The germination rate on this corn is outstanding. It is up and looking wonderful!Date published: 2012-06-08Rated 4 out of 5 by BrewBelly from Will try again... The squirrels demolished the plants, stems and all, right at flowering. They are gone to heaven now so I'll try again in the Fall.Date published: 2012-05-12Rated 5 out of 5 by vic1911 from Fantastic flavor!! For years I have enjoyed the flavor of the SU varieties (Early Sunglow), but, this one has them beat!! The flavor is a perfect balance of tradional corn and extra sweet! In my opinion, the taste is out of this world!! Productivity is average as each plant produces just one ear, although a few of my plants have produced two. Plant vigor is good, although I did have a problem early on with corn borers which was handled with an addequate application of pesticide. so far, the plants have handled the AZ heat quite well. The ears themselves are between 8-9" and loaded with kernals and have a good thick husk. So, if the SU varieties are too much like field corn for your taste, give this one a try!! Highly reccommended!!Date published: 2010-06-06Rated 5 out of 5 by Jedediah from Exactly as described This year the stalks were short but the ears were long...long and full. Very full. Lives up to the name, that's for sure. Great for anything, maybe even making shine.Date published: 2008-10-07Rated 5 out of 5 by Anonymous from early extra sweet corn My husband and i have grown this corn for years.
