About carrots
Carrots are a cool-season root crop that rewards good soil preparation above all else. They need loose, stone-free soil to form straight roots, and patience during their slow germination. Sown in spring and again in midsummer for fall, they sweeten dramatically after a frost.
When to plant and harvest carrots
Timing is relative to your frost dates. Find your USDA zone for exact dates, or browse the month-by-month calendars.

How to grow carrots step by step
- 1
Prepare deep, loose, stone-free soil — rocks and clods cause forked roots.
- 2
Sow ¼ in deep and keep the surface constantly moist until germination (2–3 weeks).
- 3
Thin seedlings to 2–3 in — crowded carrots stay small and twisted.
- 4
Keep weeded and evenly watered as roots size up.
- 5
Harvest from summer, or leave fall carrots in the ground after frost for extra sweetness.
Common problems growing carrots
⚠ Forked or twisted roots
Caused by rocky soil, clods, or fresh manure — improve soil texture and avoid high-nitrogen amendments.
⚠ Poor germination
The surface dried out — keep it moist; covering with a board or burlap helps until sprouting.
⚠ Carrot rust fly
Use row cover and avoid thinning at dusk when the flies are active.
✗ Keep away from
🧺 Harvesting carrots
Pull when shoulders reach the desired size; water first to loosen soil. Fall carrots can stay in the ground under mulch and be dug as needed.
Carrots: frequently asked questions
When should you plant carrots?＋
In most regions you transplant direct-sow only — or direct sow 3 weeks before last frost, then midsummer for fall. Timing is relative to your last frost, so find your USDA hardiness zone for the exact planting dates where you live.
Why are my carrots short and forked?＋
Heavy, rocky, or recently manured soil causes deformed roots. Grow in deep, loose, stone-free soil or raised beds.
How long do carrots take to germinate?＋
2–3 weeks — slower than most crops. Keep the soil surface constantly moist during that time.
