SOW

When to Sow Carrot Chantenay Royal in the UK

Sow directly outdoors from March to July, about 1cm deep.

Use that window as a practical starting point rather than a fixed deadline. In colder or exposed areas, delay outdoor sowing and planting; in mild sheltered areas, the earlier end of the range may work. Tender crops should remain protected until frost risk has passed.

Sowing Indoors

Carrots dislike transplanting, so do not start them in ordinary modules. For an early crop, sow directly into the final container under glass or a cloche.

Sowing Outdoors

Sow Carrot Chantenay Royal thinly about 1cm deep in prepared, stone-free soil. Water the drill before sowing and avoid handling foliage unnecessarily when thinning, as the scent can attract carrot fly.

03

PLANT

Spacing and Planting Out

Thin to 3–5cm for smaller roots or 5–7.5cm for maincrop carrots. Keep rows 20–30cm apart in beds; in pots, use a staggered grid.

Before planting outside, harden off indoor-raised plants over 7–10 days unless the crop is fully hardy and already accustomed to outdoor conditions. Water the planting hole or container first and avoid leaving young roots exposed to sun or wind.

SMALL SPACES

Growing Carrot Chantenay Royal in Pots and Containers

Choose a straight-sided container at least 25cm deep, filled with fine, stone-free peat-free compost. Sow directly and thin without disturbing the remaining roots. Paris Market is the best shallow-pot choice; Autumn King needs the most depth.

Container checklist

  • Use drainage holes and raise pots slightly so surplus water can escape.
  • Fill with fresh peat-free compost suited to edible crops.
  • Leave a watering lip below the rim and check pots more often in sun or wind.
  • Use a strong support at planting time if the mature crop will climb or become top-heavy.
05

CARE

Watering and Feeding

Water during dry spells, especially in containers, but avoid switching between bone-dry and saturated conditions. Fresh compost usually supplies enough food; excessive nitrogen produces leafy, forked roots.

Variety note: Its short wedge-shaped roots suit containers and heavier or shallower soils better than long carrots.

06

WATCH FOR

Common Problems

Carrot fly

Use fine insect mesh from sowing to harvest and keep containers raised where practical. Remove thinnings rather than leaving them beside the crop.

Forked roots

Stones, compacted compost, fresh manure or root disturbance cause branching. Use a fine loose growing medium.

Green shoulders

Exposed root shoulders can turn green. Draw a little compost around them without burying the foliage.

07

PICK

Harvesting Carrot Chantenay Royal

Lift from June to November, roughly 12–16 weeks after sowing.

Allow about 12–18 weeks, lifting a test root when shoulders reach a useful size. Harvest in the coolest part of the day where practical and handle produce gently. Regular picking encourages continued cropping in fruiting and cut-and-come-again plants.

08

GROW TOGETHER

Companion Plants

Spring onions, radishes and lettuce can share a nearby trough if each crop keeps enough spacing. Mesh protection and clean sowing practice are more reliable against carrot fly than companion planting.
