🥔 Chitting Potatoes: The Ultimate Guide to a Stronger, Faster Harvest

Chitting potatoes is a simple but powerful technique that gives your crop a head start, leading to earlier harvests, stronger plants, and often better yields. By encouraging seed potatoes to sprout before planting, you reduce time in cold soil and help plants establish quickly once planted out.

This ultimate guide explains what chitting is, how to do it properly, when to start in the UK, and common mistakes to avoid.

🌱 What Is Chitting?

Chitting is the process of pre-sprouting seed potatoes before planting them outdoors. It involves placing potatoes in a cool, bright location so strong shoots develop from the eyes.

Chitted potatoes:

• Grow faster once planted
• Establish more quickly
• Often crop earlier
• Can produce more consistent results

🗓️ When to Start Chitting Potatoes (UK)

Timing depends on the type of potato:

• First earlies: late January to February
• Second earlies: February to early March
• Maincrop: March

Start chitting 4–6 weeks before planting time.

🥔 How to Chit Potatoes Step by Step

1️⃣ Choose Healthy Seed Potatoes

• Firm, unblemished tubers
• No signs of rot or mould
• Multiple visible eyes

2️⃣ Position Potatoes Correctly

• Place potatoes with the eyes facing upwards
• Use egg boxes, trays, or crates
• Keep potatoes separated for airflow

3️⃣ Provide the Right Conditions

• Bright but indirect light
• Cool temperatures (5–10°C)
• Frost-free and dry

Avoid dark cupboards—this causes long, weak shoots.

4️⃣ Let Shoots Develop

• Shoots should be short, thick, and sturdy
• Ideal length: 1–2 cm
• This usually takes 4–6 weeks

🌱 Do All Potatoes Need Chitting?

Chitting is most beneficial for:

• First early potatoes
• Second early potatoes
• Cold or heavy soil conditions

Maincrop potatoes don’t strictly need chitting, but it can still help in shorter growing seasons.

✂️ Should You Rub Off Extra Shoots?

For best results:

• Leave 3–4 strong shoots per potato
• Gently rub off weaker or excess shoots

This focuses the plant’s energy into fewer, stronger stems.

🌾 Planting Chitted Potatoes

When planting:

• Handle shoots carefully—they snap easily
• Plant with shoots facing upwards
• Don’t delay planting once shoots are ready

Chitted potatoes can be planted slightly shallower than unchitted ones.

❌ Common Chitting Mistakes

• Chitting in the dark
• Allowing shoots to grow too long
• Starting too early with nowhere to plant
• Letting potatoes get frosted
• Using supermarket potatoes (often treated)

Avoid these and results improve dramatically.

🌟 Is Chitting Worth It?

For most UK gardeners: yes.

Benefits include:

• Earlier harvests
• Faster establishment
• Better performance in cool soils
• More reliable cropping

It takes very little effort and can make a noticeable difference.

🌟 Final Tips for Success

• Start chitting at the right time for your potato type
• Aim for short, strong shoots
• Keep potatoes cool and bright
• Handle carefully when planting
• Don’t rush planting into cold, wet soil

Chitting potatoes is one of the simplest ways to improve your harvest. With minimal effort and no special equipment, you’ll enjoy stronger plants and faster results—making it well worth doing each year.
