The Bitterness Beneath the Stairs: A Winter Chicory Crop for People With No Greenhouse

By mid-November, my balcony has entered its quiet, sulky phase. The pots are sodden, the light is thin and anything still trying to grow out there looks like it has been told off. But the best crop of the month is not outside at all. It is in a biscuit tin at the back of the cupboard under the stairs, quietly doing something useful in the dark.

This is chicory forcing, and it is one of those small-space projects that feels almost like a magic trick. You take roots that spent the summer on a balcony or in a modest pot, pack them into a damp tin, shut the lid and wait. A few weeks later you get chicons: tight, pale, crunchy little heads with a bitterness that wakes up a winter salad. No greenhouse, no grow light, no heated propagator. Just a cupboard and a bit of patience.

Why chicory is the small-space winter cheat

Witloof chicory is a two-part plant. In its first year it builds a fat taproot and a rosette of leaves. That root stores energy. If you lift it in autumn and then force it in the dark, the plant spends that stored energy pushing out a compact head instead of a sprawling leafy plant. The darkness matters because it keeps the leaves pale and tender rather than green and tough.

For anyone growing on a balcony, that is a lovely thing. You are not asking for more space, more light or more heat. You are asking a root to do one last job in a cupboard. It suits the Lockdown Garden spirit perfectly: small space, big seasonal cheer, and a certain amount of quiet smugness when lunch comes from under the stairs.

What you actually need

A biscuit tin is ideal, but an old ice-cream tub or a deep plastic tray with a lid will do. You want something dark, roughly upright and deep enough for the roots to stand in. Line the bottom with damp compost, coir or even scrunched newspaper. The medium should be damp, not soggy. Think wrung-out sponge, not puddle.

You also need chicory roots. If you grew them, lift them before the worst of the frost. Trim the leaves to about 2–3cm above the crown and trim the taproot so it fits the tin, keeping as much of it as you sensibly can. Brush off loose soil rather than washing the roots. Pack them upright and fairly snug, then add more damp compost around them so they are supported but not buried to the neck.

Put the lid on, leave it slightly ajar for a little air, and put the tin somewhere dark and cool. A cupboard under the stairs is good. A cool pantry is good. An airing cupboard is not — too warm, and you tend to get loose, floppy growth rather than tight chicons.

The UK timing bit

Late October to late November is the useful window for lifting and starting to force. If your roots are in pots, tip them out and sort through them. Anything thin, forked or damaged can go on the compost heap. The fat, straight roots are the ones worth forcing. You can also lift roots and store them in damp sand or compost for a few weeks before forcing, which is handy if you want a staggered supply rather than a chicory mountain in one go.

In a cool cupboard, expect chicons in roughly three to five weeks. Check the tin weekly. If the compost has dried out, damp it again. If there is condensation running down the lid, wipe it and leave the lid a little more open. You are aiming for dark and humid, not dark and swampy.

The supermarket shortcut, honestly

If you did not grow roots this year, the supermarket can still help — but it is worth being realistic. A pack of chicory heads from the supermarket is not a pack of forcing roots. You can stand the trimmed base of a head in a saucer of water in the dark and get a few small bitter leaves, which is a fun little experiment, but it will not give you proper chicons.

The better shortcut is to look for chicory roots themselves. Some greengrocers, veg boxes and winter markets sell them, and they are worth grabbing if you spot them. Otherwise, ask around an allotment site or a local gardening group. Chicory growers often have more roots than they can force, and a handful of spare roots is a very good thing to be given in November.

Cupboard versus chilly balcony

This is the bit that surprises people. A dark cupboard can outperform a chilly balcony in December because chicory forcing wants steady, moderate cool — not freezing, not fluctuating, not bright. A balcony in December gives you all the wrong things: cold snaps, wet compost, low light and the occasional gale. The cupboard gives you consistency. And consistency is what turns a root into a decent chicon.

That said, do not force in a warm kitchen. Warmth pushes soft, leafy growth and invites mould. A cool, dark corner is the sweet spot. If the cupboard smells fusty, open the lid for an hour and check that nothing is sitting in water.

Harvest and eating

When the chicons are firm and about 10–15cm tall, they are ready. Twist them off at the base or cut them cleanly. Most roots give one good chicon, sometimes a smaller second one. Do not expect supermarket uniformity. Expect character.

Eat them raw with orange segments, blue cheese and walnuts. Braise them with butter and a little stock until tender. Halve them, oil them and roast them cut-side down until the edges caramelise. The bitterness is the point — it cuts through rich winter food and makes a plate feel brighter than the weather deserves.

The small print

Keep an eye out for grey fluff. If a chicon starts to rot, remove it and wipe the tin. Do not overwater. Do not cram roots in so tightly that air cannot move. And do not panic if the first attempt is modest. Chicory forcing is one of those projects that improves with practice, and even a small, slightly wonky harvest feels like a small victory in the darkest weeks of the year.

A biscuit tin, a damp handful of compost and a dark cupboard is not much of a production line. But in November, when the balcony is mostly a place for looking at rather than doing in, that is exactly the kind of low-effort, high-cheer project worth making room for.
