🥔 Step 1: Choose the Right Seed Potatoes
- Use certified seed potatoes (not supermarket ones)
- Check they are:
- Firm
- Free from mould or rot
- Not shrivelled
👉 Seed potatoes are disease-checked and grow far more reliably.
📅 Step 2: Start at the Right Time
Start chitting 4–6 weeks before planting out.
Typical UK timings:
- Late January–February: First early potatoes
- February: Second earlies
- Late February–March: Maincrop (optional)
If unsure, February is the safest month for most gardeners.
🪟 Step 3: Pick a Bright, Cool Location
Potatoes need:
- Light (to keep shoots short and strong)
- Cool temperatures (5–10°C is ideal)
- Dry, frost-free conditions
Best places:
- Cool windowsill
- Porch or hallway
- Spare room with a window
❌ Avoid dark cupboards and warm kitchens.
📦 Step 4: Set Potatoes Up Correctly
- Place potatoes rose end up
(the end with most small eyes) - Use:
- Egg boxes
- Seed trays
- Shallow boxes
- Space them so shoots don’t touch
No compost. No water. Just place and leave.
🌱 Step 5: Let the Chits Grow (and Do Nothing!)
This is the easy part.
- Don’t water
- Don’t cover
- Don’t move them unless needed
Over the next few weeks:
- Eyes swell
- Shoots appear
- Chits thicken and colour up
Rotate trays occasionally so all sides get light.
👀 Step 6: Know What “Good Chits” Look Like
Perfect chits are:
- Short (1–3 cm)
- Thick and sturdy
- Green or purple in colour
- Usually 1–3 shoots per potato
Long, pale shoots mean it’s too warm or too dark.
🚫 Step 7: Avoid Common Beginner Mistakes
- ❌ Chitting in darkness
- ❌ Keeping potatoes too warm
- ❌ Letting shoots grow very long
- ❌ Crowding potatoes together
If shoots stretch, move potatoes to a cooler, brighter spot.
🌱 Step 8: Plant When Conditions Are Right
Plant chitted potatoes when:
- Soil is workable (not frozen or waterlogged)
- Frost risk is reducing
- Shoots are still short and firm
Handle gently—don’t snap the chits.
🧠 Quick Beginner Summary
- Buy seed potatoes
- Start chitting 4–6 weeks before planting
- Use a bright, cool spot
- Place rose end up
- Leave them alone
- Plant once chits are short and sturdy
That’s it.
🧠 Key Takeaway
Chitting potatoes is one of the simplest ways for beginners to improve success. It takes almost no effort, no equipment, and very little space—but it makes planting easier and growth more reliable, especially in the unpredictable UK spring.
Get the light and temperature right, be patient, and your potatoes will do the rest.
