How to Grow Carrots
Carrots are a staple of the allotment — sweet, crisp, and colourful when home-grown. They prefer light, stone-free soil, steady moisture, and minimal disturbance. With staggered sowings, you can enjoy them from early summer right through to winter.

January
🧤 Plan & Prepare
-
Choose varieties:
-
‘Nantes 2’ or ‘Early Nantes’ for early crops
-
‘Autumn King’ for maincrop and storage
-
‘Paris Market’ for small or container gardens
-
-
Choose a sunny, well-drained bed.
-
Avoid freshly manured soil (causes forking).
-
Begin digging and removing stones from soil to make it fine and crumbly.
February
🌱 Soil Prep
-
Rake soil into a fine tilth.
-
Cover beds with fleece or cloches to warm the soil before sowing.
-
Prepare raised beds or deep containers if your soil is heavy.
March
🌾 First Sowing (Early Varieties)
-
Sow early varieties under cloches or fleece.
-
Draw shallow drills 1 cm deep, spaced 15–20 cm apart.
-
Sow seeds thinly (too close = overcrowded roots).
-
Cover lightly with soil and water gently.
-
Protect with fleece against carrot fly.
April
🌿 Main Sowing Time Begins
-
Continue sowing every 3–4 weeks for a steady crop.
-
Thin seedlings to 2–3 cm apart once they’re about 2 cm tall.
-
Water well after thinning to settle the soil.
-
Mulch lightly if the soil dries out.
-
Keep fleece on for pest protection.
May
☀️ Strong Growth
-
Sow maincrop varieties now for late-summer harvests.
-
Keep rows weed-free — hand weed carefully to avoid disturbing roots.
-
Water during dry spells to prevent splitting.
-
Continue thinning gradually for evenly spaced roots.
June
🥕 Care & Watering
-
Keep soil moist but not waterlogged.
-
Avoid pulling up carrots unnecessarily — scent attracts carrot fly.
-
Feed with a low-nitrogen fertiliser if needed.
-
Sow final batches of early or baby carrots for autumn harvests.
July
🌾 Growing Steadily
-
Maincrops filling out now.
-
Keep fleece on or use carrot fly barriers (about 60 cm high).
-
Remove weeds carefully by hand.
-
Water deeply in hot weather.
August
🥕 Harvest Time for Early Varieties
-
Lift early crops when roots are firm and full-sized.
-
Leave maincrop carrots to swell for autumn.
-
Sow late, short-rooted varieties for overwintering under cloches.
-
Keep fleece on if carrot fly is still active.
September
🍂 Main Harvests Begin
-
Pull maincrops as needed.
-
Harvest before heavy frost to prevent cracking.
-
Store clean, dry roots in boxes of sand or sawdust in a cool, dark shed.
-
Remove all debris from beds to avoid attracting pests.
October
🌱 Storage & Soil Care
-
Finish harvesting and store remaining carrots.
-
Mulch soil beds with compost for winter protection.
-
Start digging and preparing new carrot beds for next spring.
November
🌾 Maintenance Month
-
Check stored carrots regularly — remove any that are soft or rotting.
-
Continue clearing weeds and old foliage.
-
Spread compost over next year’s carrot bed (not fresh manure).
December
🧤 Rest & Plan
-
Enjoy stored carrots in stews and roasts.
-
Review what worked well this season.
-
Order fresh seed for next year — carrots lose viability quickly.

🌤 Tip of the Season
“Carrots grow best when left undisturbed — sow thinly, keep them covered, and let nature do the shaping.”
