How to Grow Potatoes in a Raised Bed

Raised beds solve two potato problems at once: drainage and loose soil for tuber expansion and harvest.

Why beds work well

• Soil warms earlier in spring
• Roots avoid winter puddles
• You can build a fluffy mix over time
• Pathways stay compacted while beds stay diggable

Planting in a bed

Use the same fundamentals as in-ground culture:

• Plant when soil is ~45°F
• Depth 3–5 inches
• Spacing about 8–12 inches
• Leave room along the bed to hill

In narrow beds, plant a single row down the center or two staggered rows if width allows.

Rotation matters more in permanent beds

Nightshade diseases build up. Avoid planting potatoes where tomatoes, peppers, eggplant, or potatoes grew for the past 3–4 years when you can (UMN guidance). In a small raised-bed garden, rotate beds by year or grow potatoes in bags some seasons.

Soil mix

Aim for the same targets as best soil for potatoes: loose, well drained, slightly acidic.

Harvest gently with a fork from the side of the bed to reduce damage → How to Harvest Potatoes
