Corn, Early Sunglow Hybrid

Short Description

Great early variety, thrives in cool weather.

Full Description

Early Sunglow is a great choice for areas with short growing seasons and cool springs. The height is 4 to 4 1/2', and the extra-early, uniform ears are about 7" long with 12 rows of deep kernels. Stalks yield 2 ears. Proven tops for productivity, flavor and wide adaptability. Garden-fresh sweet corn is one of summer's greatest pleasure. Don't miss this one. A packet contains enough for four 15' rows. Seeds are not treated. Garden Hints: Plant corn in blocks, at least four rows wide, for cross-pollination and well-filled ears. Grows best in full sun (at least 6 hours of direct sun per day). Cultivate carefully to avoid damaging surface roots.

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.

Corn, Early Sunglow Hybrid is rated 3.2 out of 5 by 18.
Rated 1 out of 5 by from Bad seeds I've purchased these seeds and not a single germination. I've tried a different method and nothing. I've purchased seeds from a different company and all of their seeds germinated. I've concluded it was Burpee seeds. Not happy

Rated 1 out of 5 by from Don't bother I'm a big time gardener. I got these seeds at a local garden center. This is the worst variety of corn I ever grew. Low vigor, tiny ears, not even that early. Wasted space and $$.

Rated 5 out of 5 by from Earliest variety I could find that's still decent Early corn is not as high quality as main season varieties but you can eat it for two weeks while waiting for those. It's best as a first planting and does NOT do well in fall as a last planting, at least in the Mid Atlantic. But it's much better than store corn. Like other earlies, plants are short.. tassels show at 2 feet and plants are spindly 5 feet high but they will produce one good ear per stalk in Mid Atlantic early summer conditions, sometimes two. Further north (State College PA, 1979) I got mostly two per stalk in much cooler conditions which favors higher yield. I've grown it for forty years in various locations and it rarely fails. I usually plant two crops of Early Sunglow in mid spring about ten days apart and then switch to a late variety such as Silver Queen or Peaches and Cream for the rest of the season.

Rated 2 out of 5 by from Very early, not much flavor. I grew three types of corn this year, the Early Sunglow for the first time. It really grew nice little plants, but the flavor & sweetness just wasn't there. Luckily, our Breeders Choice is just 2 weeks behind. We also grow Golden Jubilee. I won't get this one again, but may still use the red stalks for deco this Halloween.

Rated 4 out of 5 by from So Far, So Good... Even though Early Sunglow is classified as "early", here in Z6 MA our winter Spring has been crazy with spring temps fluctuated between Feb 70-80's to March 10's - our Spring has been all over the map confusing fruit trees and flowering shrubs. I elected to start the seeds indoors to "control" outcome. Out of 32 seeds planted - 30 germination and grew to 6". Transplanted out to corner area of garden protected by 6' fence both sides to shield from SW/W storms. The plants are thriving, strong balanced growth across all 30 plants. this corn seems very easy to grow. However, at 20-24" the plants are tasseling! Coming from the Midwest this is shocking to see early tasseling at such a small size. The bedding is compost, kept watered so the persistent June heat (more like August heat) may be the reason for early tasseling. I'm thinking the stalks will continue to grow and produce sweet corn. So far the vigor of this corn is good. I expect the flavor to be good as well.

Rated 1 out of 5 by from Germination problems I planted this the same day, same garden, same conditions as some peaches&cream from another vendor. I always like to plant one packet of early sweet corn. The peaches&cream germination was essentially 100%, but the Early Sunglow was ~20% germination - very poor. I had a similar experience in 2015, but didn't have the 'control' side-by-side to show it was the seed and not the conditions (was very wet in 2015).

Rated 5 out of 5 by from Always Reliable We have been growing Early Sunglow for nearly 20 years and it has never failed us. We refer to it as our "Thanksgiving corn" because we always freeze a big bag to serve with the Thanksgiving meal. It is planted several weeks earlier than any other sweet corn we plant and it always germinates, providing the first sweet corn in mid-July while we are waiting until August for all the other corns. The ears are smaller and less sweet than other corns we grow and have a true corn flavor.

Rated 1 out of 5 by from Early Sunglow Hybrid Sooo very disappointing! I was so excited to be planting corn for my very first time and everything seemed to be going along smoothly. However, we just harvested a few ears today - after reading and educating myself how to tell when corn is ready - and can not believe how disappointing this corn was. The kernels were nice and plump, but it had absolutely no flavor. No sweetness detected at all. I will try again next year with corn, but it will not be this type! Geez, now what to do with the couple other dozen I have still standing in my garden????
