Why Grow Your Own Potatoes
Potatoes are ideal for home growing because they:
- Produce high yields from small spaces
- Grow well in UK conditions
- Suit beds, containers, and grow bags
- Store well when grown correctly
They are perfect for beginners and experienced gardeners alike.
Choosing the Right Potatoes to Grow
Potatoes fall into three main types:
First earlies – Quick-growing, ready in around 10–12 weeks, best eaten fresh
Second earlies – Slightly larger crops, ready in 12–14 weeks
Maincrop – Larger yields, best for long-term storage, ready in 16–20 weeks
Always use certified seed potatoes for healthier plants and better results.
Chitting Seed Potatoes (Optional)
Chitting encourages faster growth, especially for early potatoes.
- Place seed potatoes in a light, frost-free place
- Allow short, sturdy shoots to develop
- Takes around 4–6 weeks
Maincrop potatoes can be planted without chitting if preferred.
When to Plant Potatoes in the UK
Plant potatoes once soil temperatures reach 7–10°C.
- Early potatoes: Late February to March (under cover or mild areas)
- Maincrop potatoes: Late March to mid-April
Avoid planting into cold or waterlogged soil.
Preparing the Soil
Good soil preparation is key to success.
- Choose a sunny position
- Loosen soil deeply
- Add compost or well-rotted manure
- Avoid fresh manure
Potatoes prefer loose, fertile, well-drained soil.
How to Plant Potatoes
- Dig trenches 10–15cm deep
- Space potatoes 30–40cm apart
- Place with shoots facing upwards
- Cover with soil
Water lightly if conditions are dry.
Growing Potatoes in Containers
Potatoes grow well in:
- Grow bags
- Buckets
- Large containers
Ensure good drainage and consistent watering. Container-grown potatoes need more frequent watering than ground-grown crops.
Earthing Up Potatoes
Earthing up is essential.
- First earth-up when shoots reach 15–20cm
- Repeat as plants grow
This:
- Prevents greening
- Protects from frost
- Encourages higher yields
Watering Potatoes
Water regularly, especially:
- During flowering
- When tubers are forming
Inconsistent watering leads to small or misshapen potatoes. Deep, steady watering works best.
Feeding Potatoes
Potatoes are moderate feeders.
- Use a balanced fertiliser at planting
- Avoid high-nitrogen feeds later
- Do not overfeed
Too much nitrogen causes leaf growth instead of tubers.
Common Potato Problems
- Lots of leaves but no potatoes – excess nitrogen
- Green potatoes – poor earthing up
- Small tubers – uneven watering
- Blight – warm, humid conditions
Most problems can be prevented with correct care and timing.
When to Harvest Potatoes
- Early potatoes: Harvest when plants flower
- Second earlies: Harvest as needed once mature
- Maincrop: Harvest after foliage yellows and dies back
Leave maincrop potatoes in the ground for 1–2 weeks after dieback to allow skins to toughen.
Drying and Curing Potatoes
After harvesting:
- Dry potatoes for 24–72 hours
- Cure maincrop potatoes for 10–14 days in dark, ventilated conditions
This improves storage life significantly.
Storing Potatoes Long Term
Store potatoes:
- At 4–8°C
- In darkness
- In breathable containers
Check regularly and remove any spoiled potatoes promptly.
Final Thoughts
Growing potatoes from start to finish is a simple process built on good soil, correct timing, regular watering, and proper harvesting. By following each stage carefully, you can enjoy reliable harvests and homegrown potatoes that last well into winter.
Potatoes reward steady care with excellent results.
