Show Stump Carrots: Grow a Matched Set

Stump-rooted carrots are the short, blunt-ended class at a village veg show, and the prize goes to the best-matched set. Judges want roots that look like quadruplets: the same length, the same shoulder, clean orange skin and a tidy rounded end. This guide covers growing them forking-free in sand, keeping carrot fly off, and getting them to the bench unmarked.

If you’re new to showing, the village veg show guide explains how classes, schedules and novice entries work. This page sticks to the stump carrot class.

What do judges look for in stump carrots?

Judges look for a uniform set of clean, well-coloured roots with a blunt end. Size matters far less than matching.

Points to aim for:

• Matching: every root the same length, width and shape
• Shape: straight, smooth, ending in a neat rounded stump, not a taper
• Colour: even orange right up to the top, with no green shoulders
• Skin: clean and unmarked, with no splits, fly tunnels or scuffs
• Tops: trimmed neatly, all to the same length

Your show schedule says how many roots go on the plate. Read it before you sow, so you grow plenty of spares. The long carrots for show guide covers the other carrot class, where length is everything. The allotment show judging guide explains how judges compare one dish with another.

Best varieties for stump carrot classes

Pick a blunt-ended, Nantes-type carrot and stick with one variety for the whole dish. Mixing varieties makes matching much harder.

Avoid long, tapering types such as Autumn King. They don’t fit the stump class. The best carrot varieties guide covers flavour and kitchen use if you want to grow some for eating too.

How to grow stump carrots in a sand-filled drum

A drum of stone-free sandy mix is the simplest way to get straight, smooth roots. Ordinary soil hides stones and lumps that make carrots fork.

1. Use a large plastic tub or barrel, at least 45cm deep, with drainage holes drilled in the base.
2. Stand it on bricks so water drains freely.
3. Fill with a stone-free mix of sharp sand and sieved peat-free compost. Mix in a small handful of general fertiliser, but no manure.
4. Water well and let it settle for a week or two, then top up.
5. Push a dibber in about 25-30cm deep to make holes roughly 10-15cm apart.
6. Fill each hole with fine sieved mix and firm it gently.

A deep bed of sieved, stone-free soil works too if you’d rather not use drums. The idea is the same: nothing for the root to bump into.

A dibber makes deep holes in the drum, which you then fill with fine sieved mix. The root grows straight down through soft, stone-free sand.

When to sow stump carrots for a show

Sow from late April to May, about three to four months before the show. Sow too early and the roots can get too big or split before show day.

Sow a couple of seeds on each filled hole and thin to the strongest later. Even spacing makes it easier to grow a matching set.

• Shows in early August: sow in late April
• Shows in late August: sow in early to mid May
• Shows in September: sow in mid to late May

Sow two or three seeds on top of each filled hole, cover with about 1cm of sieved mix and water with a fine rose. Thin to the strongest seedling once they’re up. Pinch out the spares rather than pulling them, so the smell doesn’t draw in carrot fly.

Sowing a second drum a week or two later is good insurance. Weather varies, and a spare batch often gives the best set.

Watering and feeding show carrots

Water little and often so the mix never dries out completely. Sudden soaking after a dry spell splits roots.

• Water with a fine rose every few days in dry weather
• Skip extra nitrogen: it gives lush tops and hairy, forked roots
• A liquid seaweed feed now and then is plenty
• Keep the drum weed-free, pulling weeds gently by hand

How to keep carrot fly off show carrots

Cover the crop with fine insect mesh from sowing to lifting. One carrot fly tunnel ruins a show root.

Carrot fly larvae tunnel into the roots. The adult flies stay low, and they find carrots by smell. A barrier of fine mesh at least 60cm tall around the drums keeps most out. A full mesh cover over the top is safer still. A resistant variety helps, but it isn’t enough on its own.

Grow drums away from where you grew carrots last year. The carrot root fly guide covers barriers, timing and other ways to cut the risk.

A tall mesh fence around the drums keeps low-flying carrot flies away. Pin the bottom edge down so nothing sneaks underneath.

Lifting stump carrots for show day

Lift the day before the show or on the morning. Carrots go soft and lose their shine quickly once they’re out of the ground.

1. Water the drum well the evening before so the mix is soft.
2. Loosen the mix around the root with your fingers.
3. Hold the tops low down and ease the carrot up with a gentle wiggle. Don’t yank.
4. Lift a few more than you need, so you can pick the best match.
5. Wrap them in a damp cloth and keep them somewhere cool and dark.

Washing and staging show stump carrots

Wash gently with a soft sponge and cool water. A brush or scourer scratches the skin, and judges notice.

1. Soak the roots briefly in cool water to loosen the sand.
2. Wipe them clean with a soft sponge.
3. Rinse in clean water and pat dry with a soft towel.
4. Trim the tops neatly to the same short length with sharp scissors.
5. Snip off any straggly fine roots at the tip.

Don’t oil, polish or use detergent. Lay your roots out together and choose the closest match by length, width and colour.

A soft sponge and cold water clean the skin without scratching it. A brush leaves marks the judge will spot straight away.

On the bench, set the roots side by side with the tops to the back, or as your schedule asks. Keep them close but tidy, and check the count against the schedule before you walk away.

A well-matched plate wins over one giant carrot. Same length, same shoulders, same colour is what catches the judge’s eye.

Common mistakes with show stump carrots

• Using garden soil in the drum. Stones and lumps make roots fork. Use stone-free sandy mix.
• Too much nitrogen. Manure or rich feed gives big tops and hairy, forked roots.
• No carrot fly cover. One tunnel ruins a root. Mesh from sowing to lifting.
• Scrubbing with a brush. It scratches the skin. Use a soft sponge.
• Lifting days early. Roots go limp. Lift the day before or on the morning.

Frequently asked questions

What is a stump-rooted show carrot?

It’s a short carrot with a blunt, rounded end rather than a long point. Stump classes are judged on a well-matched set with clean skin, good colour and a tidy, blunt end. Length is not the aim, which is the big difference from the long carrot class.

Which varieties are best for stump carrot classes?

Choose a reliable blunt-ended Nantes type. Flyaway F1 and Sytan are popular because they also resist carrot fly a little. Eskimo F1 holds well for later shows. Long types such as Autumn King are wrong for the class.

How do I stop show carrots forking?

Grow them in stone-free sandy mix, not ordinary soil. Make a hole with a dibber, fill it with fine sieved mix and sow a couple of seeds on top, thinning to one. Stones, lumps and fresh manure are the usual causes of forked roots.

When should I lift stump carrots for a show?

Lift them the day before the show or on the morning. Carrots soften quickly once lifted. Water the drum the evening before so they slide out cleanly, then keep them cool and dark, wrapped in a damp cloth.

How do I wash show carrots without damaging them?

Soak them briefly in cool water, then wipe with a soft sponge. A brush scratches the skin and judges will spot it. Rinse in clean water, pat dry with a soft towel and never use detergent or oil.
