Growing your own potatoes is one of the most satisfying things you can do as a beginner gardener. Even better—you don’t need a large garden to get started. With this beginner’s guide to growing potatoes in pots, you can enjoy fresh, homegrown potatoes from a patio, balcony, or small outdoor space.
Potatoes are highly resilient, productive, and ideal for UK conditions. Whether space is limited or you are just beginning your gardening journey, growing potatoes in pots is straightforward, practical, and fulfilling.
Why Grow Potatoes in Pots?
If you’re new to gardening, container growing is an excellent way to start.
Benefits of growing potatoes in pots:
- Ideal for small gardens, patios, and balconies
- Better control over soil quality and drainage
- Fewer problems with pests like slugs
- Easy to harvest without digging up the garden
- Great for experimenting with different potato varieties
In the UK, where the weather can be unpredictable, pots also allow you to move plants if needed, giving your potatoes the best chance to thrive.
Best Types of Potatoes for Pots
Not all potatoes are identical, and selecting the right type makes a significant difference.
1. First Early Potatoes
- Ready in 10–12 weeks.
- Smaller, tender potatoes
- Great for beginners
Examples:
- Rocket
- Swift
- Arran Pilot
2. Second Early Potatoes
- Ready in 13–15 weeks
- Slightly larger yields
Examples:
- Charlotte
- Nicola
3. Maincrop Potatoes
- Take longer (15–20 weeks)
- Larger potatoes for storage
Examples:
- Maris Piper
- King Edward
👉 Beginner tip: Start with the first early potatoes. They’re quicker and less prone to disease.
What You Need to Get Started
Before you start growing potatoes in pots, assemble a few essentials.
Basic supplies:
- Large containers (at least 30–40 litres)
- Quality multi-purpose compost
- Seed potatoes (not supermarket ones)
- Watering can
- Optional: potato fertiliser
Container options:
- Plastic pots
- Grow bags
- Buckets with drainage holes
- Fabric planters
Beginner tip: Always check your containers have good drainage before planting. Poor drainage can cause roots to rot, so this step is crucial for a healthy crop.
When to Plant Potatoes in the UK
Timing matters when growing potatoes in pots.
General planting times:
- First earlies: March to April
- Second earlies: Late March to May
- Maincrop: April to May
If you’re in colder areas, wait until the risk of frost has passed, or start pots in a sheltered spot, such as a greenhouse.
Step-by-Step: Growing Potatoes in Pots
Here’s a simple step-by-step method for beginners.
Step 1: Chit Your Potatoes
Before planting, allow seed potatoes to sprout.
- Place them in a cool, bright place.
- Leave for 2–4 weeks until shoots appear.
This helps them grow faster once planted.
Step 2: Prepare Your Pot
- Add about 10–15 cm of compost at the bottom.
- Place 2–3 seed potatoes on top (depending on pot size)
Step 3: Cover with Compost
- Add more compost to cover the potatoes.
- Leave space at the top of the pot.
Step 4: Water Lightly
- Keep the soil moist but not soggy.
- Avoid overwatering at this stage.
Step 5: Earth Up as They Grow
As shoots appear:
- Add more compost to cover stems.
- Repeat until the pot is full.
This process increases your yield and protects developing potatoes from sunlight.
Where to Place Your Pots
Potatoes love sunlight.
Ideal conditions:
- At least 6–8 hours of sunlight daily
- Sheltered from strong winds
- Good airflow to prevent disease
A sunny patio or south-facing garden spot is perfect.
Watering and Feeding Tips
Mastering watering is crucial to success.
Watering:
- Keep soil consistently moist.
- Water more during warm weather
- Avoid letting pots dry out completely.
Feeding:
- Use a high-potash fertiliser once plants are established.
- Feed every couple of weeks for better yields.
Beginner tip: Keep up with watering and avoid irregular patterns, as inconsistent watering is a major cause of small or misshapen potatoes.
When and How to Harvest
This is the exciting part!
Harvest times:
- First earlies: 10–12 weeks
- Second earlies: 13–15 weeks
- Maincrop: 15–20 weeks
Signs they’re ready:
- Plants start to flower (for early potatoes)
- Leaves turn yellow and die back (for maincrop)
How to harvest:
- Tip the pot upside down.
- Gently sift through compost.
- Collect your potatoes
No digging required—perfect for beginners!
Common Mistakes Beginners Should Avoid
Even easy crops like potatoes can go wrong if you’re not careful.
1. Using small containers
Small pots = small harvests. Always go bigger.
2. Poor drainage
Waterlogged soil can rot potatoes.
3. Not earthing up
Exposed potatoes turn green and become inedible.
4. Overcrowding
Too many seed potatoes in one pot reduces yield.
5. Irregular watering
Leads to uneven growth and poor-quality potatoes.
