Chitting Potatoes: Is It Really Necessary?

Chitting Potatoes: Is It Really Necessary?

If you’ve spent time in gardening circles, you’ve probably heard the word “chitting” tossed around come spring. But what does it mean—and do you actually need to do it for a successful potato harvest? Let’s dig into the details!

What is Chitting?

• Definition:
  Chitting is the process of allowing seed potatoes to sprout before planting.
• Typically done by setting tubers “eyes up” in a bright, cool place several weeks ahead of time.

Why Do Gardeners Chit Potatoes?

• Faster Growth:
  Pre-sprouted potatoes get off to a quicker start once they’re in the ground.
• Earlier Harvest:
  Especially helpful for first earlies or if you’re aiming for the soonest possible crop.
• Healthier, Stronger Plants:
  Chitting encourages sturdy, short shoots rather than long, pale ones (which happen in the dark).

How to Chit Potatoes

1. Set Seed Tubers in Trays/Egg Boxes:
   Space them so none are touching and place the end with most eyes facing up.
2. Location:
   Keep in a cool, bright but frost-free spot (like a windowsill, porch, or shed).
3. Wait for Shoots:
   Ideally, you want 2–3cm (1 in) sturdy green shoots before planting—this takes 2–4 weeks.

Is Chitting Essential?

• First Earlies:
  Yes—chitting gives these an important head start since their season is short.
• Second Earlies/Maincrops:
  Optional but still helpful for a faster kick-off, especially in cooler climates.
• If You’re Late:
  If planting time is nearly here, or you’ve bought pre-sprouted tubers, you can skip chitting.

Potential Downsides

• Don’t chit in the dark! Long, white, brittle shoots can easily snap off and may actually slow potatoes down.
• Extra time and space—if you don’t have a suitable spot, don’t worry, potatoes will still grow without chitting.

Pro Chitting Tips

• Rub off all but 2–3 of the strongest shoots per tuber just before planting for bigger, healthier potatoes.
• Evidence suggests chitting is most useful for early and small-space growers—large-scale farms generally skip it.
