The short answer: plant seed potatoes 8 to 12 inches apart in the row, with 24 to 36 inches between rows. For most home gardens, 12 inches between seed pieces and 30 inches between rows is the most forgiving layout. Use 8 to 9 inches if you want smaller new potatoes or you are short on room. Use 15 to 20 inches if your goal is fewer but larger storage potatoes.
That number matters, but it is not the whole job. Potatoes need loose soil volume, space for hilling, enough airflow to dry leaves, and access for harvesting without compacting the growing zone. On our job sites, the same rule applies whether we are laying out a patio, drainage trench, or garden bed: the finished result depends on layout, access, and water movement as much as the measurement itself.
This guide gives you practical potato spacing for in-ground rows, raised beds, and grow bags, plus seed counts, 2026 cost expectations, planting depth, and the mistakes that shrink a harvest.
Best Potato Spacing for Most Home Gardens
For a standard backyard vegetable row, set seed potato pieces 10 to 12 inches apart. Keep rows 30 to 36 inches apart if you have the space. That gives the plants enough room to grow foliage, set tubers, and be hilled without turning the bed into a tight maintenance problem.

If your garden is small, you can tighten the row spacing to 24 inches, but that is about as narrow as we would go for a normal in-ground row. Anything tighter makes hilling harder, reduces airflow, and makes harvest messier. You may still grow potatoes, but you will work harder for them.
Use this simple spacing rule:
- 8 to 9 inches apart: best for new potatoes, small tubers, and limited space.
- 10 to 12 inches apart: best all-around spacing for home gardeners.
- 15 to 20 inches apart: best when you want larger storage potatoes.
- 24 inches between rows: workable in a tight garden if you can still hill and harvest.
- 30 to 36 inches between rows: easier for hilling, watering, airflow, and digging.
Close spacing usually increases the number of tubers but reduces individual potato size. Wider spacing gives each plant more soil, nutrients, and water, which helps produce larger potatoes. That is the tradeoff.
Spacing by Harvest Goal
Before you mark the row, decide what kind of harvest you want. A gardener pulling tender potatoes in early summer does not need the same layout as a gardener trying to store full-size potatoes through winter.
For New Potatoes
Plant seed pieces 8 to 9 inches apart. New potatoes are harvested young, often when plants are flowering or soon after. Since the tubers do not need to reach full storage size, closer spacing is reasonable.
Recommended Free Tools
A 10-foot row at 8-inch spacing takes about 15 seed pieces. Expect smaller potatoes, earlier digging, and less storage life. This layout is useful in a raised bed or small kitchen garden where fresh eating matters more than maximum size.
For General Home-Garden Potatoes
Plant seed pieces 10 to 12 inches apart. This is the most dependable choice for most homeowners. It leaves enough room for a good tuber set without wasting garden space.
A 10-foot row at 12-inch spacing takes about 10 seed pieces. Based on common Extension yield ranges, that row might produce roughly 6 to 20 pounds depending on variety, soil, watering, fertility, disease pressure, and timing.
For Large Storage Potatoes
Plant seed pieces 15 to 20 inches apart. This wider spacing reduces competition and gives tubers more room to size up. It is especially useful for maincrop varieties grown for baking, mashing, or storage.

Large potatoes still need loose soil, steady moisture, and adequate fertility. If the soil is compacted or dries out hard between waterings, wider spacing alone will not deliver a heavy crop.
How Far Apart Should Potato Rows Be?
Potato rows should be 24 to 36 inches apart. The right number depends on how you plan to maintain the row.
Use 24 inches between rows only when space is tight and you can still reach both sides. Use 30 inches for a balanced home-garden layout. Use 36 inches if you want easier access for hilling, mulching, irrigation lines, and digging with a fork.
Rows need more space than many homeowners expect because potatoes are not a plant-it-and-ignore-it crop. You will come back to hill soil or mulch around stems, check moisture, manage weeds, and dig the crop. If the rows are too close, you end up stepping into the root zone. Compacted soil limits tuber expansion and makes harvest harder.

Think of the row layout as a small construction access plan. You need a planting zone and a working zone. If every plant cannot be reached without walking on the bed, the layout is too tight.
Planting Depth and Hilling
Plant seed potato pieces about 3 to 6 inches deep. In cool spring soil, many gardeners plant closer to 3 or 4 inches so the soil warms faster and shoots emerge sooner. In dry, sandy, or fast-draining soil, 5 to 6 inches can help keep seed pieces from drying out.
The goal is not to bury the plant once and walk away. Potatoes form tubers along underground stems, and those tubers must stay covered. Light exposure turns potatoes green and can increase bitter, unsafe compounds. Once plants are 6 to 8 inches tall, pull loose soil or mulch around the stems, leaving several inches of leafy growth exposed. Repeat as the plants grow.
Most gardens need hilling during the first month after emergence, then additional loose cover as needed. Straw, shredded leaves, compost, or loose soil can work, but avoid packing heavy clay tightly against the stems. Potatoes like coverage, not concrete.

Use the table below to plan before buying seed potatoes. Seed size varies, but a common seed piece is roughly 1.5 to 2 ounces and should have at least one or two eyes. A practical rule of thumb is about 15 pounds of seed potatoes per 100 feet of row.
| Row length | In-row spacing | Seed pieces needed | Approx. seed potatoes | Typical harvest range |
|---|---|---|---|---|
| 10 feet | 8 inches | About 15 pieces | About 1.5 to 2.0 lb | Often smaller tubers; roughly 6-20 lb depending on conditions |
| 10 feet | 12 inches | About 10 pieces | About 1.5 lb | Commonly 6-20 lb per 10-foot row |
| 20 feet | 12 inches | About 20 pieces | About 3 lb | Roughly 12-40 lb in a well-managed home garden |
| 50 feet | 8 inches | About 75 pieces | About 7.5 to 10 lb | Higher tuber count, smaller average size |
| 80 feet | 12 inches | About 80 pieces | About 10 to 12 lb | Good general production layout |
| 100 feet | 12 inches | About 100 pieces | About 15 lb | Can exceed 200 lb under strong conditions |
Yields vary widely. A 10-foot row may produce 6 to 15 pounds in modest conditions, while strong soil and management can push closer to 20 pounds. Across 100 feet of row, experienced gardeners with good fertility, disease-free seed, and consistent irrigation may harvest over 200 pounds.
2026 Seed Potato Costs and Budget
Seed potatoes are not usually the expensive part of a small potato bed. Soil, compost, lumber, irrigation parts, and delivery often cost more. Still, seed cost affects variety choice and how much you plant.
For 2026, broad commodity references put US seed potatoes around $0.65 per pound, but that is not what most homeowners pay at retail. Local feed stores and garden centers commonly run about $1.15 to $2.00 per pound when sold loose. Specialty online seed potatoes often land around $3.70 to $6.40 per pound in small packs once packaging and shipping are included.

That is a good reminder that delivered cost is often driven by shipping, not the potato itself.
For one 10-foot row, plan on roughly 1.5 pounds of seed potatoes. If you buy locally, that row may cost about $3 to $5 in seed. If you order specialty varieties online, it may be closer to $6 to $10 or more. If you build a new raised bed, the seed may be the smallest line item on the project.
Raised Bed Potato Spacing
In a raised bed, potatoes still need room. Do not space them like lettuce or carrots. A good raised-bed layout keeps plants reachable and leaves room for hilling.
For a 4-by-8-foot raised bed, use two rows running the 8-foot length. Space the rows about 18 to 24 inches apart, with seed pieces 10 to 12 inches apart in each row. That gives you about 16 to 20 plants in the bed, depending on exact spacing and edge clearance.

If you stagger the rows, keep enough room to hill around each plant. Staggering can help use space efficiently, but overcrowding turns the bed into a root competition box. Leave at least 8 to 12 inches from the bed edge so soil does not spill out during hilling and tubers are not pressed against boards or blocks.
Raised beds are useful where native soil is heavy clay, poorly drained, rocky, or contaminated. They also make harvest easier because the soil is usually looser. The tradeoff is cost. A new bed may require lumber or metal edging, several cubic feet of soil mix, compost, and irrigation. That can cost several times more than planting a simple in-ground row where the existing soil is already workable.
Grow Bag and Container Spacing
For grow bags, think in terms of soil volume per plant. A 10-gallon grow bag should usually hold 1 to 2 seed pieces. A 15-gallon bag can handle 2 to 3 seed pieces. A 20-gallon container may handle 3 to 4 plants if the soil is loose, fertile, and evenly watered.
Do not stack multiple layers of seed potatoes in a bag expecting a tower of potatoes. In practice, layering often creates too much competition and produces many tiny potatoes. Start with several inches of loose mix, plant the seed pieces, and add soil or mulch as the stems grow.

Use a container mix that drains well. Heavy garden clay in a bag is a common failure point because it compacts, stays wet, and limits oxygen. Containers also dry faster than in-ground beds, so check moisture regularly during tuber formation. Wide moisture swings can cause cracks, knobs, hollow centers, and uneven sizing.
Soil, Water, and Fertility Matter More Than Cramming Plants
If you want more potatoes, the first answer is usually better soil, not tighter spacing. Potatoes perform best in loose, well-drained soil with enough organic matter to hold moisture without staying soggy.
A practical target pH is acidic to slightly acidic. Many potato-growing recommendations land around 5.3 to 6.0, and some garden guidance runs lower, around 4.8 to 5.5, especially where common scab is a concern. Do not add lime to a potato bed unless a soil test says you need it. Higher pH can make scab pressure worse in susceptible varieties.
Potatoes are heavy feeders, but too much nitrogen is a classic mistake. It can produce lush green tops and a disappointing crop underneath. Use compost to improve soil structure, then apply a balanced vegetable fertilizer or potato-appropriate fertilizer based on a soil test. Side-dressing during early growth can help, but avoid pushing soft, late-season growth when tubers should be maturing.

Seed Potatoes: What to Buy and How Much
Use certified disease-free seed potatoes whenever possible. Grocery-store potatoes are a poor shortcut. They may be treated to slow sprouting, and they can introduce diseases that remain in the garden for years.
Buy seed potatoes early in the season. Variety selection drops quickly in many parts of the US, especially for specialty, organic, fingerling, and disease-resistant types. If scab is common in your area, choose resistant varieties and avoid raising soil pH.
Cut larger seed potatoes into pieces about 1.5 to 2 ounces, each with at least one or two eyes. Small seed potatoes can be planted whole. After cutting, many gardeners let pieces cure briefly so cut surfaces dry before planting, especially if soil is cool or damp. Do not plant mushy, moldy, or shriveled pieces.

Layout Examples for Common Gardens
One 10-Foot Row
Set a string line, open a shallow furrow, and plant 10 seed pieces at 12-inch spacing. Keep the row at least 30 inches from the next major planting row if possible. This is the simplest layout for a first potato crop.
Two Traditional Rows
For two 10-foot rows, plant 20 seed pieces at 12-inch spacing. Use 30 to 36 inches between rows. You will need roughly 3 pounds of seed potatoes. Keep a walking path on at least one side so you can hill and harvest without stepping directly over the plants.
4-by-8 Raised Bed
Run two rows lengthwise. Place seed pieces 10 to 12 inches apart, offset slightly if desired. Plan for about 16 to 20 plants. Leave room at the edges for soil movement during hilling.
Small Patio Grow Bags
Use one or two seed pieces in a 10-gallon bag. Place bags where they get sun, drain freely, and can be watered without flooding a patio, deck, or foundation edge. Avoid placing heavy wet containers on surfaces not designed for the load.
Safety, Utilities, and Permit Notes
A typical potato row does not require a building permit, but site conditions still matter. Before digging a new in-ground bed, especially one that involves deeper soil work, edging, irrigation lines, or a larger landscape change, contact 811 before you dig. Utility marking is free in most areas and prevents serious damage and injury.
Check HOA rules before building raised beds in front yards, side yards, drainage easements, or shared spaces. Some communities regulate bed height, materials, placement, and visibility. In planned communities, raised garden bed guidelines may also address setbacks, approved materials, and drainage.
Keep garden beds away from foundation drainage paths unless the grade is already correct. Do not build a raised bed that traps water against siding, stucco, crawlspace vents, or basement walls. Leave working clearance around air-conditioning equipment, meters, cleanouts, and hose bibs. A productive garden should not create a maintenance problem for the house.
Common Potato Spacing Mistakes
The biggest mistake is planting too close and expecting large potatoes. Tight spacing can work, but the result is usually more small tubers, not a basket of large bakers.
The second mistake is leaving rows too narrow. Potatoes need hilling, airflow, and digging space. A row that looks efficient on planting day can become a tangled, hard-to-maintain strip by midseason.
Other common problems include planting in cold, wet soil; skipping hilling; using grocery potatoes; letting tubers green in sunlight; over-fertilizing with nitrogen; and letting the soil swing from dry to saturated. In containers, the most common mistake is crowding too many seed pieces into too little soil.
Also watch the soil itself. Heavy clay, construction-compacted soil, and poorly drained low spots are hard on potatoes. If your shovel bounces off the ground or water sits after rain, fix the bed before you tighten the spacing.
When to DIY vs. When to Hire a Pro
Planting potatoes is a good DIY project if you already have a workable garden bed, basic tools, and a water source nearby. A homeowner can lay out a 10-foot row in less than an hour, and the seed cost may be under $10 for a small planting.

DIY is usually the right call for one or two rows, a few grow bags, or a simple raised bed kit on level ground. You need a tape measure, stakes or string, a shovel or hoe, compost, seed potatoes, and a way to water consistently.
Consider hiring help when the work becomes a site project rather than a planting task. That includes regrading a wet yard, building multiple permanent raised beds, installing irrigation, correcting drainage near the house, removing compacted fill, or working around utilities and hardscape. The cost will be driven less by potatoes and more by labor, soil volume, hauling, lumber or masonry, drainage material, and access.
A pro-built garden area should solve water movement first, then planting convenience. Beds should be reachable from both sides, paths should shed water, and irrigation should cover the root zone without soaking the house or pavement. Good layout makes the garden easier to use for years, not just for one potato crop.
Bottom Line
For most homeowners, plant potatoes 10 to 12 inches apart with rows 30 to 36 inches apart. Tighten to 8 or 9 inches for new potatoes. Widen to 15 to 20 inches for larger storage potatoes. Plant 3 to 6 inches deep, hill as plants grow, and keep the soil loose, covered, and evenly moist.

Frequently Asked Questions
How far apart should seed potatoes be planted?
Plant seed potato pieces 8 to 12 inches apart. Use 8 to 9 inches for smaller new potatoes, 10 to 12 inches for general harvest, and 15 to 20 inches for larger storage potatoes.
How far apart should potato rows be?
Space potato rows 24 to 36 inches apart. A 30- to 36-inch row spacing is easier for hilling, airflow, watering, and harvest access.
How many seed potatoes do I need for a 10-foot row?
At 12-inch spacing, a 10-foot row needs about 10 seed pieces. At 8-inch spacing, it needs about 15 seed pieces. Plan on roughly 1.5 pounds of seed potatoes for a 10-foot row.
How deep should potatoes be planted?
Plant seed potatoes about 3 to 6 inches deep. Use shallower planting in cool spring soil and deeper planting or mulch where soil dries quickly.
Can potatoes be planted too close together?
Yes. Tight spacing usually produces more but smaller potatoes, and it can make hilling, watering, airflow, and harvesting harder. For large potatoes, widen spacing to 15 to 20 inches.
Do I need to call 811 before digging a potato bed?
For a new in-ground bed, irrigation trench, edging, or any deeper digging, contact 811 before you dig. Utility marking is free in most areas and helps prevent dangerous damage.
