🥔 How to Grow Potatoes: A Detailed Planting Guide for Beginners and Experts
🌱 Introduction: Reliable Potatoes Start With the Basics Done Well
Potatoes are one of the most rewarding crops to grow, whether you’re planting your very first row or refining techniques for higher yields. They’re adaptable, productive, and forgiving—but getting the planting stage right has a huge impact on harvest size, health, and timing.

🥔 Choosing the Right Potatoes to Grow
Potatoes are grouped by harvest time:
- First Earlies – Fast-growing, harvested early summer
- Second Earlies – Slightly larger, harvested mid-summer
- Maincrop – Heavier yields, best for storage
Beginners often succeed fastest with first or second earlies, while experienced growers favour maincrop for bulk harvests.
📅 When to Plant Potatoes in the UK
Typical planting times:
- First earlies: Late March
- Second earlies: Early to mid-April
- Maincrop: Mid to late April
Plant when soil temperatures are above 7°C and no longer waterlogged. Cold, wet soil is the biggest cause of failure.
🌱 Preparing the Soil Properly
Potatoes prefer:
- Loose, well-drained soil
- Plenty of organic matter
- A slightly acidic to neutral pH
Before planting:
- Dig over the ground deeply
- Remove stones and compacted clods
- Add well-rotted compost or manure
- Avoid fresh manure—it encourages disease
Good soil preparation reduces scab and misshapen tubers.
📏 How Deep and How Far Apart to Plant
General spacing guidelines:
- Depth: 10–15 cm
- Between potatoes: 30 cm
- Between rows: 60–75 cm
Plant with chits facing upward if pre-sprouted, but orientation is forgiving—potatoes will correct themselves.
🌿 Growing Potatoes in Different Setups
In the Ground
Best for large harvests and maincrop varieties. Allows deeper rooting and steadier moisture levels.
Raised Beds
Warm up faster in spring and drain well. Ideal for early planting but require regular watering.
Containers & Bags
Excellent for small spaces. Use at least 30–40 litres of compost per potato for decent yields.
🌱 Earthing Up: Why It Matters
As plants grow:
- Draw soil up around stems
- Cover emerging shoots gradually
- Repeat every 1–2 weeks
Earthing up:
- Protects shoots from frost
- Prevents tubers turning green
- Encourages higher yields
Stop once ridges are well formed.
💧 Watering Potatoes Correctly
Potatoes need consistent moisture, especially:
- When flowering starts
- As tubers begin swelling
Water deeply but infrequently. Avoid waterlogging, which causes rot and disease.
🌼 Feeding for Better Yields
Potatoes are moderate feeders:
- Too much nitrogen = leafy growth, fewer tubers
- Balanced feeds encourage steady development
Apply fertiliser at planting time and avoid overfeeding later in the season.
🚫 Common Potato Growing Mistakes
- Planting into cold or wet soil
- Overcrowding plants
- Skipping earthing up
- Overwatering containers
- Using diseased or damaged seed potatoes
Most problems are caused by rushing the planting stage.
🥔 When and How to Harvest Potatoes
- Earlies: Harvest when plants flower
- Maincrop: Harvest after foliage yellows and dies back
For storage potatoes:
- Leave tubers in the ground 10–14 days after foliage dies
- Lift in dry weather
- Allow skins to set before storing
🧠 Expert Tips for Consistent Success
- Rotate potato beds yearly to prevent disease
- Avoid growing where tomatoes grew the previous year
- Mulch lightly in dry weather
- Remove flowers to redirect energy to tubers
Potatoes reward steady care, not constant attention.
🧠 Key Takeaway
Growing potatoes successfully is about soil preparation, spacing, and timing, not complicated techniques. Whether grown in the ground, raised beds, or containers, potatoes thrive when planted into workable soil, earthed up regularly, and watered consistently during tuber formation.
Master the basics, and potatoes will remain one of the most reliable and productive crops in your garden year after year.
