Growing Sweet Corn in Your Backyard: A Comprehensive DIY Guide
Okay, so you want to grow sweet corn in your backyard? Awesome! It’s totally doable, and there’s nothing quite like biting into a freshly picked, homegrown ear of corn. Trust me, the flavor difference between store-bought and homegrown is night and day. This guide will walk you through everything you need to know, from prepping the soil to harvesting your delicious bounty. Let’s get started!
Choosing the Right Sweet Corn Variety
First things first, you need to pick the right variety of sweet corn for your area. Different varieties have different maturity dates, disease resistance, and, of course, flavor profiles. Here’s what I consider:
* Days to Maturity: This is crucial! Check your local growing season length. You need a variety that will mature before the first frost. Look for this information on seed packets or online descriptions. Early-season varieties mature in 60-70 days, mid-season in 70-85 days, and late-season in 85-100 days.
* Disease Resistance: Some varieties are more resistant to common corn diseases like rust, smut, and Stewart’s wilt. If you’ve had problems with these in the past, definitely choose a resistant variety.
* Kernel Color: Yellow, white, or bi-color (yellow and white kernels) – it’s all about personal preference!
* Sugar Content: “Sugary enhanced” (se) and “supersweet” (sh2) varieties are popular because they stay sweet longer after harvest. Supersweet varieties need to be isolated from other corn types to prevent cross-pollination, which can result in starchy kernels.
* My Personal Favorites: I’ve had great success with ‘Silver Queen’ (white, late-season), ‘Golden Bantam’ (yellow, early-season), and ‘Honey Select’ (tri-sweet blend, mid-season).
Preparing the Soil: The Foundation for Success
Corn is a heavy feeder, meaning it needs a lot of nutrients to grow well. Proper soil preparation is absolutely essential.
* Soil Testing: Before you do anything, get your soil tested! This will tell you the pH level and nutrient content. You can usually get a soil test kit from your local extension office or garden center. Corn prefers a soil pH between 6.0 and 6.8.
* Sunlight: Corn needs at least 6-8 hours of direct sunlight per day. Choose a location in your yard that gets plenty of sun.
* Soil Amendment: Corn thrives in well-drained, fertile soil. Amend your soil with plenty of organic matter, such as compost, well-rotted manure, or leaf mold. I usually add a 2-3 inch layer of compost and till it into the top 6-8 inches of soil.
* Fertilizing: Based on your soil test results, you may need to add fertilizer. Corn needs nitrogen, phosphorus, and potassium. A balanced fertilizer like 10-10-10 or 12-12-12 can be used, but follow the instructions on the package carefully. I prefer to use a slow-release organic fertilizer.
Planting Your Sweet Corn: Getting it Right
Timing is key when planting sweet corn. You want to plant after the last frost date in your area, when the soil temperature has warmed to at least 60°F (15°C).
* Planting Time: Wait until the soil is warm. A soil thermometer is your best friend here.
* Planting Depth: Plant seeds about 1-2 inches deep and 6-12 inches apart in rows that are 30-36 inches apart.
* Planting Pattern: Plant corn in blocks of at least four rows, rather than one long row. This helps with pollination. Corn is wind-pollinated, so the more plants you have close together, the better the pollination will be.
* Succession Planting: To extend your harvest, plant a new batch of corn every 2-3 weeks. This will give you a continuous supply of fresh corn throughout the season.
* Watering: Water thoroughly after planting. Keep the soil consistently moist, but not waterlogged, until the seedlings emerge.
Caring for Your Sweet Corn: Nurturing Your Crop
Once your corn seedlings emerge, it’s important to provide them with the care they need to thrive.
* Watering: Corn needs about 1 inch of water per week, especially during tasseling and silking (when the tassels and silks appear). Water deeply and infrequently, rather than shallowly and frequently. Soaker hoses or drip irrigation are great options.
* Weeding: Keep the area around your corn plants free of weeds. Weeds compete with corn for water and nutrients. Hand-pulling weeds is best, but you can also use a hoe or cultivator. Be careful not to damage the corn roots.
* Fertilizing: Side-dress your corn plants with nitrogen fertilizer when they are about 12 inches tall and again when the tassels begin to emerge. Side-dressing means applying fertilizer along the sides of the rows, about 6 inches away from the plants.
* Pest Control: Corn earworms, corn borers, and aphids are common pests of sweet corn. Inspect your plants regularly for signs of infestation. You can use insecticidal soap, Bacillus thuringiensis (Bt), or other organic pest control methods to control these pests. I usually hand-pick earworms when I see them.
* Supporting the Stalks: In windy areas, you may need to support your corn stalks to prevent them from falling over. You can use stakes or tie the stalks together with twine.
Pollination: Ensuring Full Ears of Corn
Proper pollination is essential for producing full, well-filled ears of corn.
* Understanding Pollination: Corn is wind-pollinated. The tassels at the top of the plant produce pollen, which is carried by the wind to the silks on the developing ears. Each silk is connected to a kernel on the cob. If a silk is not pollinated, the kernel will not develop.
* Helping Pollination: If you’re growing corn in a small area or if the weather is calm, you can help with pollination by gently shaking the corn stalks in the morning when the tassels are shedding pollen. You can also cut off a tassel and gently brush it against the silks.
* Watering During Pollination: Make sure your corn plants are well-watered during tasseling and silking. Water stress can reduce pollen production and silk receptivity.
Harvesting Your Sweet Corn: The Sweet Reward
Harvesting sweet corn at the right time is crucial for getting the best flavor and texture.
* Timing is Everything: Corn is usually ready to harvest about 20-25 days after the silks emerge. The silks will turn brown and dry, but the husks should still be green.
* The “Feel” Test: Feel the ear of corn through the husk. It should feel plump and full.
* The “Puncture” Test: Gently puncture a kernel with your fingernail. If the liquid that comes out is milky, the corn is ready to harvest. If the liquid is clear, it’s not quite ready. If the liquid is doughy, it’s overripe.
* Harvesting Technique: To harvest, grasp the ear of corn firmly and twist it downward and away from the stalk.
* Enjoy Immediately: Sweet corn is best eaten as soon as possible after harvest. The sugars in the kernels start to convert to starch soon after picking, so the sooner you eat it, the sweeter it will be.
Dealing with Common Problems
Even with the best care, you may encounter some problems when growing sweet corn. Here are a few common issues and how to deal with them:
* Poor Pollination: If your ears of corn have missing kernels, it’s likely due to poor pollination. Make sure you’re planting in blocks, not rows, and consider hand-pollinating if necessary.
* Corn Earworms: These pesky caterpillars burrow into the ears of corn and feed on the kernels. You can control them by applying Bacillus thuringiensis (Bt) to the silks or by hand-picking them.
* Corn Borers: These insects bore into the stalks of corn, weakening them and reducing yields. You can control them by removing and destroying infested stalks.
* Raccoons and Birds: These critters love sweet corn just as much as we do! You can protect your corn by using netting or fencing. Motion-activated sprinklers can also be effective.
Storing Sweet Corn
If you can’t eat all of your sweet corn right away, you can store it in the refrigerator for a few days.
* Refrigerating: Store unhusked ears of corn in the refrigerator in a plastic bag. They will stay fresh for about 2-3 days.
* Freezing: You can also freeze sweet corn. Blanch the ears in

Frequently Asked Questions (FAQ)
Q: How much space do I really need to grow sweet corn?
A: Sweet corn needs space for proper pollination. A general rule of thumb is to plant in blocks of at least four rows, rather than one long row. Each block should be at least 4 feet wide and the rows spaced about 2-3 feet apart. This ensures that the wind can effectively carry pollen from the tassels (male flowers) to the silks (female flowers) on the ears. If you’re limited on space, consider a smaller, denser block, but be mindful of potential pollination issues. You can also hand-pollinate if necessary.
Q: What’s the best type of soil for growing sweet corn?
A: Sweet corn thrives in well-drained, fertile soil that is rich in organic matter. The ideal soil pH is between 6.0 and 6.8. Before planting, amend your soil with compost, aged manure, or other organic materials to improve its structure and fertility. If your soil is heavy clay, consider adding sand or other drainage-improving amendments. A soil test can help you determine the specific nutrient needs of your soil.
Q: How often should I water my sweet corn?
A: Sweet corn needs consistent moisture, especially during germination, tasseling, and ear development. Water deeply and regularly, aiming for about 1 inch of water per week. Use a soaker hose or drip irrigation to deliver water directly to the roots, minimizing water loss through evaporation. Avoid overhead watering, as it can promote fungal diseases. Check the soil moisture regularly and adjust your watering schedule accordingly.
Q: What are some common pests and diseases that affect sweet corn, and how can I control them?
A: Common pests include corn earworms, cutworms, and aphids. Diseases include corn smut and various fungal leaf diseases. To control pests, consider using row covers, hand-picking pests, or applying organic insecticides like Bacillus thuringiensis (Bt). For diseases, ensure good air circulation, avoid overhead watering, and remove any infected plants promptly. Crop rotation can also help prevent disease buildup in the soil.
Q: When is the right time to harvest my sweet corn?
A: The best time to harvest sweet corn is when the silks have turned brown and dry, but are still slightly moist. The ears should feel plump and full, and the kernels should be milky when punctured. To test for ripeness, peel back a portion of the husk and puncture a kernel with your fingernail. If the liquid is milky, the corn is ready to harvest. If it’s clear, it needs more time. If it’s doughy, it’s overripe. Harvest in the morning for the best flavor.
Q: Can I grow different varieties of sweet corn together?
A: It’s generally not recommended to grow different varieties of sweet corn together unless they have similar maturity dates. Cross-pollination can affect the sweetness and quality of the kernels. If you want to grow multiple varieties, plant them at least 250 feet apart or choose varieties with different maturity dates to prevent cross-pollination.
Q: How can I store my harvested sweet corn?
A: Sweet corn is best enjoyed fresh, but you can store it in the refrigerator for a few days. To store, leave the husks on and wrap the ears in a plastic bag. For longer storage, you can freeze or can your sweet corn. To freeze, blanch the ears for a few minutes, then cool them in ice water before freezing. To can, follow a tested canning recipe to ensure food safety.
Q: Is it really worth the effort to grow sweet corn in my backyard?
A: Absolutely! While it requires some effort, the taste of homegrown sweet corn is unmatched. It’s sweeter, juicier, and more flavorful than anything you can buy in the store. Plus, you’ll have the satisfaction of knowing you grew it yourself. It’s a rewarding and delicious experience that’s well worth the time and effort. Growing sweet corn is a great way to connect with nature and enjoy the fruits (or vegetables!) of your labor.
