Shop NowCorn is among the most common plants to produce and consume, and it tastes much better when picked fresh. It's also simple to cultivate in a home garden. Corn develops on high, rigid stalks that yield husked ears of silk-tufted kernels. On the exterior, most corn types resemble one another. Sweet corn, however, can be white, yellow, red, and even multi color under the husks. Whereas many corn kinds have been developed to bloom early on in the season, later-maturing variants are sweeter. Sweet corn is an annual that is sown in the spring and grows throughout the summer. It is ready to harvest 3 months after planting, however early types might be available as soon as two months.

‘Golden Bantam’: An heirloom cultivar known as the first sweet corn.
Fertilizer
Corn is a strong feeder that requires fertile soil. Nitrogen is very necessary for healthy development. To feed your corn, work 2 to 5 cm of compost, decomposed manure, or fish emulsion into the soil before planting in the autumn. Provide a nitrogen fertilizer to the plants when they are approximately 20 cm tall and once when they begin to produce tassels, according to the label directions.
Soil
The ground should be loose and loamy, with a pH that ranges from slightly acidic to neutral. Corn’s fibrous root structure might be hampered by heavy soils. The thin roots that grow on the surface of the ground serve primarily to anchor tall plants. Before planting, it is often a smart option to have a soil test. Collect samples to your nearest university extension service for testing. In the spring and fall, amend the soil with very well manure or compost as needed.
Water
Water on a regular basis, especially if you detect the leaves curling or the cobs swelling. 2 cm of water each week should be plenty. It is also preferable to water thoroughly once a week rather than providing a small amount of water every day.
Light
Corn need full light to grow healthily and also have the ears expand out. On most days, this translates to at least 6 hours of direct sunlight.
Humidity and temperature
Sweet corn loves temperatures ranging from 15 to 26 degrees Celsius. In chilly soil, it will not germinate. In chilly areas, wrap the ground with black plastic before planting to help it warm up quicker in the spring. There are different types accessible for shorter seasons. As long as appropriate soil moisture is maintained, humidity is usually not a concern.
Harvesting
Each sweet corn stalk should obtain at minimum 1 ear of corn. When you notice plump, deep green ears and brown tassels, it’s time to pick corn. Squeeze to check for stiffness and a rounded, rather than a pointed, tip. Finally, use your fingernail to puncture a kernel. It is ready when it shoots milky fluids. Pull its ears down and twist to remove the cob from the stem. Because the sweetness of sweet corn disappears quickly after harvesting, enjoy eating or preserve it immediately after plucking. Sweet corn kernels may be frozen by taking them from of the ears and freezing it in a sealed jar. Boil the corn and afterwards chill this in ice water before freezing for the best results. It should last around six months in the freezer.
