Achieving Perfect Corn Spacing with Jang Seeders

Perfect corn spacing isn’t just about aesthetics. It’s about giving each plant exactly what it needs to thrive without having to fight its neighbor for sunlight, water, and nutrients. When plants are too close, they grow thin and produce small ears. When they’re too far apart, you’re just wasting valuable garden space and reducing your overall yield.

The magic of a Jang seeder is its singulation mechanism. Unlike cheap plate seeders that often drop doubles or get clogged, the Jang uses a specialized, patented roller system. Each roller has precisely sized and spaced divots that pick up a single seed, carry it to the drop tube, and release it. An internal brush ensures only one seed makes it through each time.

This system delivers near-perfect seed placement, row after row. The result is a uniform stand of corn that germinates evenly and grows at a consistent rate. This uniformity makes everything from weeding to harvesting simpler and more efficient, saving you critical time and effort throughout the season.

Jang JP-1: The Versatile Single-Row Standard

For most hobby farmers, the Jang JP-1 is the only seeder you’ll ever need. It’s the foundational tool in the Jang lineup—simple, incredibly reliable, and built to last. If you’re managing a few hundred feet of sweet corn for your family or a small market stand, this is your workhorse.

The beauty of the JP-1 is its straightforward design. It does one thing exceptionally well: plant a single, perfect row. Its lightweight construction and easy maneuverability make it ideal for working in standard garden beds or navigating tighter spaces. You aren’t wrestling with a heavy, cumbersome machine.

Think of the JP-1 as the ultimate upgrade from hand-planting. It takes the guesswork and backache out of the equation, allowing you to seed a 100-foot row in minutes instead of an hour. Its versatility also means that with a simple roller change, you can go from planting corn to carrots to beans, making it a true multi-purpose investment for the diversified small farm.

Jang TD-1: Precision Planting in No-Till Soil

If you’re committed to no-till or low-till practices, you know the challenge of planting into soil with heavy surface residue. Standard seeders skate over the top or get clogged with old cover crop material. The Jang TD-1 is engineered specifically to solve this problem.

The key feature of the TD-1 is its front coulter disc. This sharp, cutting wheel slices a clean furrow through thatch, cover crop residue, and compacted soil. The seed opener follows directly behind in this clean path, placing the seed at a consistent depth for optimal germination. This is something the standard JP-1 simply cannot do effectively.

The tradeoff for this capability is increased weight and cost. The TD-1 is a heavier, more robust machine, and it requires more downward pressure to operate. It’s a specialized tool for a specific farming style. If you’re working with clean, tilled beds, the JP-1 is more than sufficient. But for those building soil health through cover cropping and minimal disturbance, the TD-1 is an essential piece of equipment.

Jang JPH-U: Handheld Seeder for Tight Spaces

Sometimes, a walk-behind seeder is overkill. The Jang JPH-U is a handheld, manually operated seeder designed for surgical precision in tight quarters. It uses the same reliable roller mechanism as its larger cousins but in a compact, portable form.

This tool shines in highly intensive planting systems. Use it to fill in gaps in a row where germination failed, or to interplant corn amongst other crops in a bio-intensive bed. If you’re experimenting with small, dense blocks of corn in a raised bed, the JPH-U gives you perfect spacing without the need to maneuver a wheeled tool.

It’s not for planting your main corn patch. Using it for long rows would be slow and tedious. But for patch-up jobs and specialized planting schemes, it’s an invaluable tool for maximizing every inch of your garden with precision.

Jang JP-2: Efficient Double-Row Corn Planting

When your corn patch grows beyond a few hobby rows, the Jang JP-2 offers a significant leap in efficiency. This model allows you to plant two rows simultaneously, effectively cutting your planting time in half compared to the JP-1. It’s the logical next step for the serious gardener or small-scale market farmer.

The JP-2 features two adjustable seeding units on a single frame. You can easily set the distance between the rows, making it perfect for planting sweet corn in standard double-row configurations that promote better pollination. This setup gives you the density you want without the time sink of making two separate passes.

While it’s more efficient, it does require a bit more attention to your bed preparation. You need a wider, flatter, and more consistent seedbed for both rows to plant at the correct depth. It’s less forgiving of uneven ground than a single-row seeder, but the time savings are well worth the extra effort in prep.

Jang JP-3: Boost Productivity with Three Rows

The Jang JP-3 is where you cross the line from a large garden to a small farm. Planting three rows at once is a massive productivity boost, ideal for anyone growing a quarter-acre or more of corn for a CSA or a busy farmers’ market stall. This seeder can lay down a significant amount of seed in a very short time.

Like the JP-2, the JP-3’s seeding units are adjustable, giving you control over in-row spacing. However, managing three rows requires very well-prepared ground. Your beds must be wide, level, and free of debris to ensure all three units engage the soil at a uniform depth. Any bumps or dips will be magnified across the wider machine.

This model represents a serious investment in efficiency. It’s for the grower whose most limited resource is time. If planting day is a major bottleneck in your operation, the JP-3 can be a game-changing tool that gets the crop in the ground quickly and perfectly.

Jang JP-5: Maximum Coverage for Market Farms

The Jang JP-5 is the top of the walk-behind line, designed for maximum coverage and speed. With five seeding units, this machine is built for market farmers who measure their corn patch in acres, not feet. It’s a serious tool for growers who need to plant thousands of seeds with precision and speed.

Operating the JP-5 effectively demands excellent bed preparation on a larger scale. It’s typically used on 30-inch or wider beds formed by a tractor, where its width can be used to its full potential. Pushing a five-row seeder requires significant effort, and it’s best suited for long, straight runs on flat ground.

This is not a tool for the average hobbyist. But for the ambitious grower scaling up their operation, the JP-5 offers unparalleled efficiency in a walk-behind seeder. It bridges the gap between hand tools and tractor-mounted equipment, allowing for rapid planting without the cost and complexity of larger machinery.

Selecting F-Type Rollers for Your Corn Seed

Owning the right Jang seeder is only half the battle; choosing the correct roller is what delivers the flawless spacing. For corn, you’ll be using the F-type rollers. The number on the roller corresponds to the number of holes drilled around its circumference, which directly determines your in-row seed spacing.

The roller has divots sized for corn, but you still need to match the hole count to your goal. Here’s a simple breakdown of the most common options:

• F-24: This roller has 24 holes, dropping seeds very close together (around 3 inches). It’s rarely used for full-sized corn but could be an option for baby corn or as a dense cover crop.
• F-12: With 12 holes, this roller gives you approximately 6-inch spacing. This is a very common choice for many sweet corn varieties, especially if you plan to thin to a final 12-inch spacing.
• F-6: This roller has 6 holes, resulting in a wider spacing of about 12 inches. This is perfect for larger dent or flint corn varieties or for growers who want to plant directly to their final desired spacing without thinning.

Before you buy, test a few seeds in the roller. Corn seed size can vary significantly between varieties. Ensure your chosen seed fits comfortably in the divot—not too tight, not too loose. Buying two or three F-rollers is a wise investment, giving you the flexibility to adapt your spacing to different corn varieties and planting strategies from year to year.

Ultimately, the right Jang planter for your corn is the one that best matches the scale of your ambition and the style of your farm. Whether you’re perfecting a few rows with a JP-1 or maximizing efficiency on a market plot with a JP-3, the investment pays for itself. You get flawless rows, stronger plants, and more time to focus on the hundred other jobs waiting for you.
