01Soil depth matters

Carrots need loose, stone-free soil to at least 30cm. Compacted ground or a buried stone splits the taproot into forks — dig deep and sieve out debris before sowing.

02Planting

Method
Direct sow thinly — carrots dislike being transplanted due to the taproot.
Soil
Deep, loose, stone-free to 30cm. Stones and compaction cause forking.
Timing
Sow spring through summer in cool zones; cooler months in the subtropics.

Planting timing varies significantly by Australian climate zone. Set your zone above (or use the Find My Climate Zone tool) for guidance tailored to your own area.

03Growing care

  • Thin to 5cm apart once true leaves appear — crowding stunts roots.
  • Keep the soil surface moist until germination, which is slow (10–20 days).
  • Hill soil lightly over shoulders to stop tops turning green.
  • Hand-weed while young; carrots compete poorly early on.

04Problems

  • Carrot fly — larvae tunnel roots; use fine mesh barriers.
  • Forking — from stony, compacted soil, or fresh manure.
  • Splitting — irregular watering, especially dry spells then heavy rain.
  • Cavity spot — dark lesions from waterlogged, poorly drained soil.

05Harvest & storage

Signs
Shoulders visible at soil surface, ~2cm across; brush soil back to check size.
Method
Loosen soil with a fork before pulling to avoid snapping roots.
Curing
None needed; twist or cut tops off close to the crown.
Storage
Cool, humid, dark — fridge crisper or damp sand. Keeps 2–4 months.
Preserving
See Root Cellaring (cool, dark storage without processing) for ways to keep a harvest surplus.
