The carrot originated in Persia (Afghanistan and Iran).  It was at first cultivated for it’s leaves and seeds.

Carrots or Postinaca as they were know was first documented by the Romans in 1CE.

Carrots were not originally orange, in fact yellow was the most popular colour in the 16thC.  The orange carrot was developed in the Netherlands in the 17th Century in honour of the House of Orange.


Carrots need to be direct sown as they are very sensitive to transplant.  An exception to this is Roly Poly.  As the seeds are so small they are prone to drying out before germination so keeping the garden moist but not soggy will help.    They do not like fresh nitrogenous fertilisers but do like fertile soil.  so do well in fine volcanic soils.

Carrots will thrive in a garden that has previously had a heavy feeding crop eg brassicas.

Beginning thinning when carrots are a few centimeters high and continue thinning as they grow allowing room for them to move.

Storing harvested Carrots:  Carrots can remain in the ground for some time.  Remove the green tops but do not wash.  Store in sand or sawdust.   Store best in the fridge if covered with water.  Can be frozen (good flavour)  dried (fair flavour, or canned (fair flavour

Seedlings Burn – hot sunny weather.  Sprinkle seedlings with water to keep moist

Forked or Misshapen Roots – stones, clods etc.  Delayed thinning.  Thin to 2-3cm apart when 5cm high.  Ensure soil does not have stones etc.

Excess Nitrogen – excessive leaf growth, small roots

Green Top (Crown) – sunlight on exposed crown.  Mound soil to ensure crown is covered.

Carrots Pale in Colour – excess Nitrogen, Lime soil, Acid soil, The variety of carrot.  Potash will increase the colour of the carrot.

Roots Cracked or Split – Caused by the inside growing faster than the outside.  Over fertilised.  Heavy rain followed by a dry spell.

Bolting/Running to Seed – Snap in cold weather.  Place a cloche over vegetables.


Aphids – leaves are stunted and deformed with clusters of insects.  Keep well watered in dry weather.

Carrot Rust Fly – roots tunneled into by grub, leaves may turn orange.  Rotate crops.  Ensure tops of carrot are covered in soil.
