Start well
Plant carrot with confidence
Sow direct. Sow about 5 mm, using clean seed-raising mix for trays and keeping the surface evenly moist until established.
- Sowing or planting depth
- about 5 mm
- Germination or establishment
- Often 14–28 days; do not let the shallow seed bed dry out while waiting.
- Spacing
- 5–8 cm
- Soil
- Loose, stone-free soil that drains freely; usually ph 6.0–7.0.
Feeding
Support steady growth
Use mature compost and avoid excessive nitrogen, which can favour leaves over roots.
Water
Keep moisture balanced
Water consistently while roots swell, without leaving the bed waterlogged.
Maintenance
What to do as it grows
Thin seedlings rather than transplanting them, and cover exposed shoulders to reduce greening.
Harvest or display
Know when it is ready
10–16 weeks. Readiness varies with variety and weather; use colour, firmness, size and the supplier's maturity notes rather than the calendar alone.
Problems and companions
Keep your patch healthy
Common watch-outs
Uneven watering, compacted soil and root-feeding pests can distort or split roots.
Useful neighbours
Leafy greens and small herbs can use nearby space without competing deeply; avoid overcrowding the root row.
People and pets
Safety note
No Patch-specific toxicity warning is recorded. That does not prove the plant is safe—check the exact species with a veterinarian or poisons service if children or pets may eat it.
Moving plants
Biosecurity note
Check local weed, invasive-plant and interstate quarantine rules before sharing or moving unfamiliar plant material.
Transparent guidance
How to use this guide
Patch gives a broad Australian starting point, not a guarantee for every variety or garden. Read the Patch methodology and sources, check the latest Bureau of Meteorology climate information, and confirm interstate restrictions through Australian Interstate Quarantine.
