Thinking about growing corn?
It’s easier than you might think.
With the right tactics, you can have a bountiful harvest. Explore these 9 tried-and-true methods for growing corn like a pro.
Let’s get growing!
Pick the Right Corn Variety
Choosing the right corn variety is key. There are so many types out there, from sweet corn to popcorn!
Think about what you want to use the corn for. Do you want something sweet to eat fresh?
Or maybe you’re aiming to make popcorn? Checking the growing conditions in your area helps too.
Some varieties do better in certain climates. Read the seed packets for details on what suits your needs best.
Prepare the Soil Properly
Good soil is a must for healthy corn plants. Start by clearing any weeds or old plants from your garden.
Corn likes well-drained, fertile soil with a pH of 6.0-6.8. You can test your soil to see where it stands.
Adding compost or well-rotted manure can give your soil a nutrient boost. Mix it in well, so the nutrients get deep into the soil where the roots will be.
Plant at the Right Time
Timing is everything! Corn seeds need the soil to be warm enough to germinate—at least 60°F (15°C).
If you plant too early, the seeds might not sprout. Depending on where you live, this might be late spring or early summer.
Planting in blocks rather than rows can make for better pollination too. Aim for spacing seeds about 12 inches apart in each direction.
Water Regularly
Corn is a thirsty plant, especially during the growing season. Make sure to water deeply but not too often.
It’s better to give it a good soak once or twice a week rather than a little bit every day. This encourages the roots to grow deep into the soil.
Mulching around the base of the plants can help retain moisture and keep weeds at bay.
Provide Enough Sunlight
Sunlight is super important for corn. Corn needs at least six to eight hours of sunlight a day to grow well.
Pick a sunny spot in your garden, away from any tall trees or buildings that might cast shade. If you live in a really hot area, some afternoon shade can actually help prevent the plants from wilting.
Watch for Pests and Diseases
Your corn plants might attract some unwanted attention from pests like corn earworms or aphids. Keep an eye out for any signs of trouble, like holes in the leaves or discolored spots.
You can use organic pest control methods like neem oil or insecticidal soap. If you spot any diseased plants, remove them quickly to avoid spreading the illness to the others.
Fertilize as Needed
Corn is a heavy feeder, which means it needs a lot of nutrients to grow tall and strong. Use a fertilizer rich in nitrogen a few weeks after planting.
Another round of fertilizing when the plants are about knee-high can give them a mid-season boost. Just follow the instructions on the fertilizer package to avoid overdoing it.
Harvest at the Right Time
Knowing when to harvest your corn is crucial. The ears are ready when the husks are green and the silk at the top has turned brown.
To check, peel back part of the husk and poke a kernel. If the liquid is milky, it’s ready to pick.
If it’s clear, give it a little more time. Harvest in the morning for the sweetest taste.
Save Seeds for Next Season
If you grew an heirloom or open-pollinated variety, you can save seeds for next year. Let a couple of ears dry out completely on the stalk.
Once they’re dry, remove the kernels and store them in a cool, dry place. This can be a fun way to get more out of your gardening efforts and ensure another season of tasty corn.
