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
- Size Matters: Beds at least 30cm (12 in) deep and 90–120cm (3–4 ft) wide are ideal.
- Add Compost: Mix in plenty of organic matter, compost, or well-rotted manure before planting.
- 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.
