How to grow sweet corn from seed
Growing your own sweet corn can be a satisfying and rewarding experience. The taste of freshly picked corn straight from your garden is hard to beat, and it’s surprisingly easy to grow! Whether you’re a seasoned gardener or a beginner, this guide will provide you with all the information you need to successfully grow sweet corn from seed.
Choose the Right Variety: When selecting corn seeds, it’s important to choose a variety that is well-suited to your climate and growing conditions. There are different types of sweet corn available, including SE (sugar enhanced), sh2 (super sweet), and su (standard). Each variety has its own characteristics, such as sweetness, tenderness, and shelf life. Consider your preferences and local growing conditions before making a decision. Remember to check the recommended planting dates for your area, as sweet corn requires warm soil to germinate properly.

This will improve the soil’s fertility and provide the necessary nutrients for the corn plants to thrive.A pH level between 5.8 and 7.0 is ideal for sweet corn.
Planting and Spacing: Sweet corn should be planted in blocks or rows to ensure proper pollination. This means planting multiple rows close together rather than a single long row. Space your seeds about 10-12 inches apart and plant them at a depth of 1-2 inches. Water the seeds immediately after planting, but be careful not to overwater as it can lead to rotting.If you’re short on space, consider planting a dwarf or mini sweet corn variety that takes up less room.
Step-by-Step Guide to Growing Sweet Corn from Seed
Growing your own sweet corn can be a rewarding experience, providing you with fresh and delicious corn that you can enjoy all summer long. Follow these steps to successfully grow sweet corn from seed.
1. Choose the Right Variety of Corn
Before planting sweet corn seeds, it’s important to choose the right variety. Consider factors such as the maturity date, taste, and disease resistance. Some popular options include Golden Bantam, Honey Select, and Ambrosia.

- Disease resistance: Consider any prevalent diseases in your area and choose a variety that shows resistance to those diseases. This can help ensure a higher success rate in your growing efforts.
By considering these factors and exploring different varieties, you’ll be on your way to growing the perfect sweet corn from seed. Happy planting!
Preparing the Soil
Before planting sweet corn seeds, it’s important to prepare the soil to provide the best growing conditions. Follow these steps to prepare the soil for sweet corn:
1. Choose a Sunny Location
Ensure that you choose a sunny location for growing sweet corn as it requires at least 6-8 hours of direct sunlight per day.
2. Clear the Area
Clear the area of any weeds or existing vegetation to prevent competition for resources. Use a rake or hoe to remove the weeds and prepare a clean canvas for planting.
3. Loosen the Soil
Loosen the soil by tilling it using a garden tiller or a hand hoe. This will help improve drainage and provide the corn roots with easier access to water and nutrients. Aim for a depth of 8-12 inches.
4. Amend the Soil
Mix in organic matter, such as compost or well-rotted manure, to improve the soil’s fertility and structure. Work the organic matter into the soil using a garden fork or tiller.
5. Test the Soil’s pH
Test the soil’s pH level using a soil testing kit. Sweet corn prefers a slightly acidic soil with a pH level between 6.0 and 7.0. If the pH is too low, add lime to raise it. If it’s too high, add sulfur to lower it.
6. Apply Fertilizer
Apply a balanced fertilizer or a slow-release fertilizer according to the manufacturer’s instructions. Make sure to evenly distribute it across the planting area and work it into the soil.
7. Create Planting Rows
Create planting rows by using a hoe or garden tool to make 3-4 inch deep furrows. Space the rows about 30-36 inches apart to provide enough room for the corn plants to grow.
8. Add Mulch
Spread a layer of organic mulch, such as straw or wood chips, between the rows to help suppress weed growth and retain moisture in the soil.
By preparing the soil correctly, you’ll be giving your sweet corn seeds the best start for healthy growth and a bountiful harvest.
Sowing the Seeds
Before you can start growing sweet corn, you need to sow the seeds. Here’s a step-by-step guide on how to sow sweet corn seeds:
- Choose a sunny spot in your garden to sow your sweet corn seeds. Make sure the soil is well-draining and fertile.
- Prepare the soil by removing any weeds and rocks, and then loosen it with a garden fork or tiller. Add compost or well-rotted manure to enrich the soil.
- Form rows in the soil about 1 inch deep and 12 inches apart. You can sow multiple rows to maximize your corn harvest.
- Place the sweet corn seeds in the row, spacing them about 6 inches apart. Cover the seeds with soil and gently press down.

- Once the sweet corn seedlings have emerged, thin them out, leaving the strongest and healthiest plants about 12 inches apart.
- Protect the young seedlings from pests like birds and squirrels by covering them with bird netting or using scare devices.
- Continue to water and care for your sweet corn plants as they grow. Aim to provide them with about 1 to 1.5 inches of water per week.
- Once your sweet corn plants have reached about 12 inches in height, you can begin fertilizing them with a balanced fertilizer, following the package instructions.
By following these steps, you’ll be well on your way to growing delicious sweet corn from seed!
Care and Maintenance
Growing sweet corn requires regular care and maintenance to ensure healthy growth and a bountiful harvest. Here are some important tips to follow:
1. Watering
Sweet corn requires regular watering, especially during dry periods. It is essential to keep the soil consistently moist, but not overly saturated. Water deeply and evenly, focusing on the base of the plants. Avoid overhead watering, as it can promote disease and rinse away pollen needed for pollination.
2. Fertilizing
Apply a balanced fertilizer when planting and continue to fertilize throughout the growing season. Sweet corn is a heavy feeder and requires nutrient-rich soil to thrive. Consider using organic fertilizers or compost for a more sustainable approach.
3. Weed Control
Keep the area around your sweet corn plants free from weeds, as they compete for resources and can hinder growth. Regularly remove weeds by hand or use mulch to suppress weed growth.
4. Pest and Disease Management
Monitor your sweet corn plants for pests such as corn earworms, aphids, and armyworms. Implement proper pest management techniques such as handpicking and the use of natural repellents. Also, watch for common diseases like corn smut and rust, and promptly address them using appropriate treatments or disease-resistant varieties.
5. Supporting the Plants
As sweet corn plants grow taller, they may require additional support. Consider using stakes, trellises, or cages to prevent the plants from bending or falling over due to strong winds or heavy fruit. This will help protect the plants and maintain proper pollination.
By following these care and maintenance practices, you can ensure healthy growth and increase the chances of a successful sweet corn harvest.
Harvesting and Storing
When the sweet corn plants have fully developed and the husks have turned brown, it is time to harvest the corn. One way to check if the corn is ready for harvesting is by peeling back the husk slightly and piercing one of the kernels with your thumbnail. If a creamy white liquid squirts out, the corn is still immature. However, if the liquid that comes out is milky or pasty, it means the corn is ready to be harvested.
To harvest the corn, hold the stalk with one hand and grip the ear of corn with the other hand. Gently pull the ear down and twist it until it snaps off from the stalk. Avoid yanking the corn forcefully as it may damage the plant. After harvesting the corn, remove the husks and silk from the ears.
If you plan to consume the corn immediately, boil a pot of water and place the ears of corn in it for about 2-3 minutes. Be careful not to overcook the corn as this can affect its taste. Serve the corn hot with butter and salt, or any desired seasoning.
Storing Fresh Corn
If you need to store the fresh corn for a few days, wrap each ear tightly in aluminum foil. This will help to keep the corn moist and prevent it from drying out. Place the wrapped ears in the refrigerator and use them within 2-3 days for the best flavor.
Freezing Corn
If you have a surplus of corn, you can also freeze it for long-term storage. Start by blanching the ears in boiling water for 4-6 minutes, then transfer them to an ice bath to cool. Once cooled, remove the kernels from the cob using a sharp knife. Place the kernels in a freezer bag or airtight container, and remove as much air as possible before sealing. Frozen corn can be kept in the freezer for up to one year.
Now that you know how to harvest and store sweet corn, you can enjoy the delicious taste of homegrown corn all throughout the year.
