🥔 Chitting Potatoes: Should You Rub Off Extra Shoots?

🌱 Introduction: A Common (and Confusing) Question

When chitting potatoes, many gardeners notice several shoots forming on each seed potato and wonder whether they should rub some off. Advice can feel conflicting—but the answer is actually quite simple.

👉 Sometimes yes, sometimes no.
It depends on the potato type, the number of shoots, and what kind of crop you want.

This guide explains when rubbing off extra shoots helps, when it’s unnecessary, and how to do it safely.

✅ When Rubbing Off Extra Shoots Is a Good Idea

You may want to rub off extra shoots if:

• A seed potato has 5 or more shoots
• Shoots are thin and crowded
• You want fewer, larger potatoes
• You’re growing early potatoes where strength and speed matter

Reducing shoot numbers helps the plant focus energy into fewer, stronger stems.

❌ When You Should Leave Shoots Alone

Do not rub shoots off if:

• There are only 1–3 strong shoots
• Shoots are thick and healthy
• You’re growing maincrop potatoes in good soil
• You want more potatoes rather than larger ones

In these cases, removing shoots offers little benefit.

🥔 Shoot Numbers by Potato Type

🌱 First Early Potatoes

• Ideal: 1–2 shoots
• Rubbing off extras can improve vigour and earliness

🌿 Second Early Potatoes

• Ideal: 2–3 shoots
• Remove only weak or excess shoots

🥔 Maincrop Potatoes

• Ideal: 2–4 shoots
• Usually no need to remove any

✂️ How to Rub Off Shoots Safely

If you decide to remove shoots, do it carefully:

1. Choose the strongest shoots to keep
2. Rub off unwanted shoots gently with your thumb
3. Remove shoots while they are short (under 2 cm)
4. Avoid snapping or twisting hard

Never use tools—your fingers are best.

🚫 Common Mistakes to Avoid

• ❌ Removing too many shoots
• ❌ Damaging the potato skin
• ❌ Removing shoots after planting
• ❌ Rubbing off healthy shoots “just in case”

Less intervention is usually better.

🌱 What Happens If You Don’t Remove Extra Shoots?

Nothing disastrous.

• Plants still grow
• You may get more but smaller potatoes
• Growth may be slightly less vigorous

This is fine for many gardeners, especially with maincrop varieties.

🧠 Quality Matters More Than Quantity

The strength of the shoots matters more than the number.

Good shoots are:

• Short and thick
• Green or purple
• Firm, not brittle

Weak, pale shoots cause more problems than extra strong ones.

🧠 Key Takeaway

You don’t always need to rub off extra shoots when chitting potatoes. Aim for 1–3 strong shoots per seed potato, and only remove extras if shoots are crowded or weak—especially for early varieties. When in doubt, do less rather than more.

Strong shoots grow strong plants.
