Otter’s useful guide to Carrots

Why grow carrots?

Carrots are a kitchen essential! They’re brilliant raw, roasted or grated into salads. By growing your own you can enjoy tender roots at every stage, from baby carrots to full‑sized beauties.

This rewarding, space‑efficient crop suits everything from deep beds to roomy containers. They provide a steady, low‑maintenance harvest and are great for gardeners, novice and experienced, who enjoy the satisfaction of pulling up these colourful veg.

Different types

There are plenty to choose from:

Short, rounder carrots ideal for containers or shallow beds.

Long, tapered types for deep, sandy soil.

Chunkier, broad‑shouldered roots that mature quickly.

Colourful options including yellow, purple and creamy white forms.

How to grow carrots

Ideal conditions

Carrots do best in light, stone‑free soil. Choose a sunny spot and prepare the ground by removing lumps and debris, then rake to a fine tilth. If your soil is heavy, try growing short or stump‑rooted types that cope better with shallow or imperfect ground.

In the ground

Sow seeds in shallow drills around 1cm deep. Carrots don’t like being transplanted, so sow where they’ll grow. Keep rows weed‑free so the roots have space to develop.

In containers

Choose a pot at least 25 to 30cm deep for longer varieties. For shorter varieties you can choose smaller containers. Use a fine, free‑draining compost and water regularly.

General advice

Watering

Carrots prefer consistent moisture. Dry spells followed by heavy watering can cause roots to crack. Water lightly but often, especially in containers which shouldn’t dry out.

Feeding

Carrots don’t need rich soil. Avoid high‑nitrogen feeds, which encourage leafy tops rather than good roots.

Thinning

Ideally sow sparsely at the start so you don’t need to thin seedlings – this can attract carrot fly.

General Tips

Sow thinly and avoid disturbing the soil too much.

Keep the soil moist to prevent splitting.

Use insect mesh or fleece to protect from carrot fly.

Some varieties are resistant to carrot fly so if you’re a beginner, try these.

When to grow

Plant from spring through early summer, and again in late summer for an autumn harvest.

Things to look out for

Pests and Diseases

  • Carrot fly; the larvae eat the roots making the crop inedible.
  • Forked roots may be caused by stony soil or fresh manure.
  • Slugs and snails are likely to enjoy young seedlings!

When to harvest

Most carrots are ready in 10 to 12 weeks. Harvest when roots look plump at the shoulders. Baby carrots can be pulled earlier for extra sweetness.
