Maincrop carrots left in wet ground much past the first hard frosts turn soft, split, or disappear to slugs overnight. Lifting them onto a box of damp sand keeps them in the same eating condition as the day you pulled them, right through to spring, and takes an afternoon for a full row.

Lift and Store Maincrop Carrots for Winter Keeping

What you need

1 wooden or plastic storage box a stackable crate or deep seed tray works
10 litres builder's sand or old potting compost lightly dampened, not wet
1 hessian sack or sheet of cardboard to line the box, optional

Step by step

Choose a dry day. Twist or snip off any foliage that has flopped over so you can see the row clearly.
5 min
Push the fork in a hand's width clear of the row and lever gently, working along the row rather than pulling carrots out by the tops, which snaps them.
20 min
Lift the carrots and knock off loose soil with your hands. Don't wash them — wet skin is what starts rot in storage.
10 min
Twist the foliage off an inch above the crown rather than cutting it with a knife, so the carrot doesn't try to regrow in the box.
10 min
Set aside any that are forked, split or chewed by slugs — eat these first, since they won't keep.
5 min
Line the box and layer the sound carrots in so they don't touch each other, covering each layer with about 2cm of damp sand or compost and finishing with a layer on top.
10 min

Afterwards

Store the box somewhere cool and frost-free, such as a shed or garage, rather than anywhere heated. Check it once a month and pull out anything that has gone soft before it spreads to the rest. Carrots layered in sand this way typically keep until around April.

Questions

Can I just leave the carrots in the ground over winter instead?

In free-draining soil, yes, with a thick straw mulch over the row. In heavy or wet ground they're prone to splitting and slug damage, so lifting into a box of sand is the more reliable route.

Do I need to wash the carrots before storing them?

No. Washing wets the skin and encourages rot. Brush off loose soil with your hands and leave the rest.

What if I don't have sand?

Old potting compost works just as well. The point is a loose, slightly damp layer that keeps the roots in the dark and stops them touching each other.

Why twist the tops off instead of cutting them?

A clean knife cut can still leave the growing point intact, and it will try to sprout in storage, drawing moisture out of the root. Twisting removes the point itself.
