How to Grow Sweet Corn from Seeds: 800 Kernels Per Plant!

Soil Secrets for 800-Kernel Success

Let me tell you something about soil that changed my corn-growing game forever. After 15 years of growing sweet corn, I’ve learned that the secret to those impressive 800-kernel ears starts way before you even think about planting. It’s all about getting your soil just right!

The Perfect pH Sweet Spot

I’ll never forget the year my corn crop was a total bust. The plants looked stunted, and the ears were pathetic. After getting my soil tested (something I should’ve done from the start!), I discovered my pH was way off at 5.2. The sweet spot for corn is actually between 6.0 and 6.8 – this range is absolutely crucial for nutrient absorption.

To adjust your soil pH, you’ll need to:

Test your soil first (don’t skip this like I did!)
Add lime to raise pH if it’s too acidic
Use sulfur to lower pH if it’s too alkaline
Retest after 2-3 weeks to confirm changes

Nutrient Mix for Giant Yields

Here’s the real game-changer: corn is what we call a heavy feeder. My best yields came when I started treating my soil like a five-star restaurant for my corn plants. The magic formula I’ve developed over the years includes:

3 parts aged compost
1 part well-rotted manure
1/2 cup of balanced fertilizer (10-10-10) per 10 square feet
A sprinkle of Epsom salts for that magnesium boost

The Double-Digging Revolution

You won’t believe the difference when you start double-digging your corn beds. I was skeptical at first – it seemed like overkill. But wow, what a difference it made! Here’s my tried-and-true method:

Dig your first trench about 12 inches deep
Loosen the soil at the bottom with a fork
Mix in your nutrients
Move to the next section and repeat

Nitrogen Timing: The Secret Weapon

Listen up, because this is where most folks go wrong with corn. Timing your nitrogen application is absolutely crucial for those 800-kernel ears. I’ve developed what I call the “Three-Stage Feeding Plan“:

First feeding: When plants are knee-high
Second feeding: When you see the first tassels
Final boost: When silks appear

Companion Planting Magic

Want to know what really revolutionized my corn growing? The Three Sisters method. Planting beans and squash alongside your corn isn’t just some old tradition – it’s backed by science! The beans fix nitrogen, while the squash keeps weeds down and retains moisture.

My favorite companions for corn include:

Pole beans (they use corn as natural trellises)
Winter squash
Marigolds (keeps those pesky corn earworms away)
Clover as a living mulch
