How to Plant Potatoes in Raised Beds

Planting potatoes in raised beds is an excellent way to improve drainage, warm the soil faster in spring, and grow healthier crops—especially in UK gardens with heavy or poorly draining soil. With the right spacing and care, raised beds can produce excellent potato harvests.

Why Grow Potatoes in Raised Beds?

Raised beds offer several advantages:

• Better drainage, reducing risk of rot
• Warmer soil for earlier growth
• Easier earthing up
• Improved soil structure and fertility
• Less soil compaction

They are ideal for first earlies, second earlies, and maincrop potatoes.

Step 1: Choose the Right Raised Bed

• Minimum soil depth: 30–40 cm
• Width: No more than 1.2 m (to reach the centre easily)
• Position: Full sun for best yields

Deeper beds are better for maincrop potatoes.

Step 2: Prepare the Soil

Potatoes need loose, fertile soil.

• Remove weeds and stones
• Mix in plenty of well-rotted compost or manure
• Avoid fresh manure (can cause scab)
• Ensure soil is free-draining but moisture-retentive

Raised bed soil should be light and crumbly.

Step 3: Decide on Layout and Spacing

In raised beds, potatoes are usually planted in rows or a staggered grid.

Recommended Spacing

• First earlies: 30 cm apart
• Second earlies: 30 cm apart
• Maincrop: 35–40 cm apart

Leave enough space between rows (or staggered plants) to allow earthing up.

Step 4: Plant at the Correct Depth

• Plant seed potatoes 10–15 cm deep
• Place with shoots (chits) facing upwards
• Cover gently with soil

Do not plant too deep—earthing up later provides extra coverage.

Step 5: Water After Planting (If Needed)

• Water lightly if soil is dry
• Do not water if soil is already moist
• Avoid soaking the bed

Overwatering at planting can cause seed potatoes to rot.

Step 6: Protect from Frost

Early in the season:

• Cover beds with fleece if frost is forecast
• Or earth up soil over emerging shoots

Raised beds warm faster but also cool faster at night.

Step 7: Earth Up as Plants Grow

Earthing up is crucial in raised beds.

• Add soil or compost around stems as shoots grow
• Keep tubers covered to prevent greening
• Build ridges up to 20 cm high

This also increases yield and protects developing potatoes.

Step 8: Water and Feed During Growth

• Water regularly during dry spells
• Most important during flowering and tuber formation
• Feed lightly with a balanced fertiliser if growth is poor

Avoid excessive nitrogen.

Step 9: Harvesting Potatoes from Raised Beds

• First earlies: Harvest when flowering begins
• Second earlies: Harvest just after flowering
• Maincrop: Harvest when foliage has died back

Raised beds make lifting easier and reduce damage to tubers.

Common Mistakes to Avoid

• Planting too close together
• Skipping earthing up
• Letting soil dry out completely
• Overfeeding with nitrogen

Raised Beds vs Containers

• Raised beds: Higher yields, easier watering
• Containers: More flexible but lower yields

Raised beds are ideal if space allows.

Quick Summary

• Soil depth: 30–40 cm
• Plant depth: 10–15 cm
• Spacing: 30–40 cm depending on type
• Earth up regularly
• Water consistently

Final Tip

Raised beds are one of the best ways to grow potatoes in the UK. With good spacing, proper earthing up, and consistent watering, you can expect clean, healthy, and productive potato crops.
