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.
Corn is classified as Sh2, SE, SU, or SY. These refer to the sweetness and how long the corn may be stored. Sh2 is is supersweet, lasts 4-6 days in the refrigerator and is more challenging to sow in cool soils; SE is sugar-enhanced and lasts over a week in the refrigerator; SU is normal sugary, more cool soil tolerant but with a shorter shelf life; SY combines SE and Sh2 traits. Isolate Sh2 corn varieties from others by planting 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 corn. 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.

Complete waste of time, money and garden spaceI needed a late summer crop for an empty space in my garden. Since we don’t eat a lot of winter vegetables (broccoli, kale, spinach, etc) I thought this corn would be the perfect option. It didn’t require a ton of space and had a fairly short maturity. I should have believed the other reviews. Abysmal germination rate. I planted the entire packet of 50 seeds (actually it was about 60) exactly per instructions. I planted in late July in western North Carolina so I know cool soil temps were not an issue. I think I counted 8 scrawny corn sprouts that look more like crabgrass. Come on Burpee. Read your reviews and either address the issue or stop selling this seed.

I had high hopesI had extremely high hopes for this container corn, as in my neighborhood we are only permitted to have raised garden beds. None of my beds have ever been large enough to plant corn, so I was excited to see a hybrid designed for this exact purpose. I ended up planting all 50 seeds knowing that corn generally has a 75% germination rate. Unfortunately, out of the 50 seed, only 15 germinated and grew. I'm not sure if I'll end up with any ears of corn, but regardless, for the price of a packet of seeds, it was not worth it to only get 15 stalks. That only equates to about a 30% germination rate.

Poor germinationThis is my 3rd year growing On Deck in a raised bed. The 1st 2 years were great, but this year I had about a 10% germination. I contacted Burpee & provided the seed packet info they asked for. I requested a refund, as I e already planted a different corn variety (which had a 100% germination rate), so I didn’t want a replacement. I just received an email stating my replacement seeds have been shipped. Not very good customer service, Burpee. I’ve always recommended your seeds to the gardeners at the community garden where I am the volunteer Garden Leader, but I certainly won’t do that anymore. Dry disappointed.

poor germinationI have grown On Deck Hybrid corn for the past 2 years with GREAT success. 6'-7' stalks with lots of corn grown in a 3'x7' raised container. This year out of a whole packet of seeds only ONE kernel came up. ??? I waited several weeks, just in case of slow starting. Tired of waiting I bought another variety of Burpee corn seeds (Farmer's First) . The ALL germinated within a week and are looking good. Don't know what the problem was with the On Deck seeds.

WeakI read several reviews saying that this variety had poor germination, but I gave it a shot anyway. After planting, I can say that germination is not the only issue this seed has.
I planted 18 seeds (2 per location) expecting low germination rates and figuring that I would just move plants around to fill in gaps. I got 12 sprouted plants from 18 seeds. No problem, I expected this. The real problem is that out of my 12 plants 5 of them died for unknown reasons. Now I'm left with 7 plants, all of which are growing at different rates.
I put these in a 26 inch container as directed, and I now have empty spots and uneven growth. If I decide to plant the rest of the seed next year I will plan on planting triple the amount I should need to just to get the 9 plants burpee recommends. I am not impressed at all.

Didn't produce as expectedOut of the whole pack of seeds, we have 3 strong stalks growing, approx. 3ft tall. 2 smaller ones planted later. Planted these on the deck in large pot, fresh soil did exactly as directions say. So yes we are disappointed that only a few grew.

Save your money!This is my third and last year attempting to grow this variety, very poor germination rate (40%). I loved the corn that grew the last times, but I will buy another brand next season.
This is in a raised bed with 60 degree soil temps and moderate water, full sun.
Tomatos, cukes, carrots, watermelon all had nearly 100% germination.

Terrible germination rates; a tale of two plantersI'm an urban gardner and I do all my gardening in fabric pots to move them as the sun shifts through the year. The pots are filled with a mixture of various types of compost and organic matter, peat to retain water, and potting soil. I also used some pelletized organic 5-5-5, worm castings, bone and blood meal to supplement the soil even more. That said, I have two 24" corn planters positioned in the "most prime" light of my entire property. That's like 15+ hours of light a day...from sunrise to sunset. I wanted to stagger my planting of each container a few weeks apart so I stagger my harvest--seems like a simple concept, eh? It's been a very warm sprummer (we've catapulted from winter to summer, skipping spring), so watching the temps, around early April I planted nine holes with 3 seeds each of On Deck in container 1 and waited two weeks. Nada. Zip. Figured maybe the soil wasn't warm enough, so I waited. Two weeks later, two little plants poked out--of the same hole! It killed me seeing total container failure knowing that one of these successful sprouts would ultimately be thinned. Put some more seeds in the soil, as now daytime temps were hitting 75-80+ and waited again. Got some sprouts, but most of them died back (three more plants were successful in this round of planting). Maybe bugs got 'em, so I tried some more seeds. Nothing. I took a couple and tried sprouting them out of the soil, a technique I found videos for on Youtube, and I had success sprouting 5 baby corn plants without soil. At least I know these seeds are going to sprout, right?! I was so proud of myself for finally not wasting any more seeds, and looking forward to, after more than a month and a half of trying, finally having 9 plants in my On Deck container. I put the 5 sprouted corn stalks in the dirt, and within 2 days all of them succumbed. Maybe transplant shock? I don't know, but I've burned darn near the whole pack of On Deck just trying to get nine plants going, so on a whim I go to a local hardware store and pick up a pack of Burpee Silver Queen seeds for $1.89. Noting that it's now been almost two months and my planting calendar's ticking, I planted nine Silver Queen holes (three seeds each) four days ago. I'm happy--if not completely frustrated--to report that it's germinated 100%--I put three per hole, and I got three seedlings from each hole. They look dark green, healthy, and are already taller than some of the On Deck's I planted a couple of weeks ago--after FOUR DAYS! The Silver Queen's been so successful, I'll need to thin them. What stings the most? I paid almost 5x as much for On Deck as I did Silver Queen (Why do Burpee seeds cost $7 + shipping online and $1.89 at a hardware store? Another topic altogether...) I feel like I totally wasted my money and my time on this On Deck variety. With 50 seeds, I have replanted the entire 24" container now twice and some holes three or four times, and I have 0 hope of them making it. I'm going to pull them all out and plant another 9 of Silver Queen in the first pot, since I have enough seeds left from that packet and the On Deck seedlings I do have look horrible in contrast to the Silver Queen ones after just four days.
