🥔 Chitting Potatoes: Common Beginner Mistakes

🌱 Introduction: Why Chitting Goes Wrong (and How to Avoid It)

Chitting potatoes is simple—but beginners often run into problems that undo the benefits. The good news is that nearly all chitting mistakes come down to timing, light, and temperature, and they’re easy to fix once you know what to look for.

This guide covers the most common beginner mistakes, why they cause problems, and how to avoid them for strong, planting-ready chits.

❌ 1. Starting Too Early

The mistake: Chitting in early January (or before) without ideal conditions.
Why it’s a problem: Shoots grow long while you’re waiting for soil to warm, becoming weak and brittle.

Do this instead:

• Start 4–6 weeks before planting
• For most UK gardens, February is ideal
• January only for first earlies with excellent light and cool temperatures

❌ 2. Chitting in Darkness

The mistake: Using cupboards, dark garages, or sheds with no windows.
Why it’s a problem: Darkness produces long, pale, fragile shoots that snap easily.

Do this instead:

• Use bright natural light
• Windowsills, porches, or bright rooms work best
• Light matters more than warmth

❌ 3. Keeping Potatoes Too Warm

The mistake: Chitting in kitchens, boiler rooms, or heated living spaces.
Why it’s a problem: Warmth causes fast but weak growth.

Do this instead:

• Aim for 5–10°C
• If it feels comfortable in a T-shirt, it’s usually too warm
• Cool and steady beats warm and fast

❌ 4. Letting Shoots Grow Too Long

The mistake: Waiting for long sprouts, thinking “bigger is better.”
Why it’s a problem: Long chits snap easily and don’t improve performance.

Do this instead:

• Plant when chits are 1–3 cm
• Short, thick shoots are ideal
• Stop waiting once shoots are sturdy

❌ 5. Overcrowding Potatoes

The mistake: Piling potatoes together in boxes or trays.
Why it’s a problem: Shoots tangle, compete for light, and break.

Do this instead:

• Space potatoes so shoots don’t touch
• Use egg boxes or shallow trays
• Give each tuber its own light and air

❌ 6. Rubbing Off Shoots Unnecessarily

The mistake: Removing healthy shoots “just in case.”
Why it’s a problem: It causes stress and delays growth.

Do this instead:

• Keep 1–3 strong shoots
• Only rub off extras if there are many thin, weak shoots
• Do it early and gently

❌ 7. Assuming Chitting Is Essential

The mistake: Believing potatoes won’t grow without chitting.
Why it’s a problem: It leads to rushed or poorly timed chitting.

Do this instead:

• Remember chitting is optional
• It helps with earliness and reliability, not survival
• Skipping chitting is better than doing it badly

❌ 8. Planting Into Cold, Wet Soil

The mistake: Planting as soon as chits are ready, regardless of soil.
Why it’s a problem: Cold, waterlogged soil delays growth and increases rot risk.

Do this instead:

• Plant when soil is workable, not wet
• Chits can wait; bad soil can’t be fixed
• Timing planting matters more than chitting length

❌ 9. Damaging Chits During Transport

The mistake: Tossing trays into bags or boxes for the allotment.
Why it’s a problem: Chits snap easily once formed.

Do this instead:

• Carry trays flat
• Handle potatoes gently
• Protect from wind and cold on planting day

👀 What Beginners Should Aim For

Perfect chitted potatoes have:

• 1–3 short shoots
• Shoots 1–3 cm long
• Thick, firm growth
• Green or purple colour

That’s all you need—nothing more.

🧠 Key Takeaway

Most beginner mistakes come from doing too much, too early, or too warm. Chitting works best when it’s simple and controlled:

Light first. Cool second. Timing third.

Get those right, and your potatoes will do the rest—no stress, no fuss, and no broken shoots.
