Growing Potatoes in Raised Beds

Raised beds are ideal for potatoes: superior drainage, loose soil for easy rooting, and less bending for planting and harvest. Here’s how to make the most of this method for healthy, productive crops.

Benefits of Growing in Raised Beds

• Improved Drainage: Prevents rot, especially in heavy or clay soils.
• Loose, Deep Soil: Promotes more tubers and easier harvest.
• Soil Warms Quickly: Jump-starts the growing season in spring.
• Tidy and Accessible: Reduces weeding and makes hilling up simpler.

Preparing Your Raised Bed

1. Size Matters: Beds at least 30cm (12 in) deep and 90–120cm (3–4 ft) wide are ideal.
2. Add Compost: Mix in plenty of organic matter, compost, or well-rotted manure before planting.
3. Loosen the Soil: Use a fork or hand tool to fluff the soil to its full depth.

Planting Potatoes in Raised Beds

• Space seed potatoes 30cm (12 in) apart in all directions.
• Make planting holes about 10–15cm (4–6 in) deep.
• Place seed potatoes eyes up, cover with soil, and water well.

Hilling Up in Raised Beds

• When shoots reach 15–20cm (6–8 in), mound soil or mulch (straw, compost) around the stems, leaving the top leaves exposed.
• Repeat every 2–3 weeks until the bed is “hilled” to its full depth—this boosts yield and prevents green potatoes.

Watering and Feeding

• Raised beds dry out faster than ground beds—check moisture regularly and water when needed.
• Apply balanced fertilizer or compost tea every few weeks for vigorous growth.

Harvesting from Raised Beds

• For new potatoes, harvest gently with your hands or a small fork when plants flower.
• For maincrop, wait until foliage dies back, then lift the whole plant and sift through the fluffy soil for your crop.

Tips for Success

• Rotate crops: Don’t plant potatoes in the same bed two years in a row.
• Mulch between plants to conserve moisture and suppress weeds.
• Try mixed beds: Combine potatoes with shallow-rooted crops like lettuce for efficient use of space.
