Pest management: Refer to carrot tips for cultural tips, pests, and diseases
When to plant: Direct seed January–March (possibly April), September
- Harvest when the roots reach 1" diameter at the top.
- Expect 90–120 days to maturity.
- Flavor is best when the mature plants are exposed to cool weather for 2–4 weeks which encourages the starches in the roots to convert to sugars.
- Loosen soil with a digging fork before pulling roots.
- Soil temperature should be >50º F for germination. Seeds are very slow to sprout at that temperature (3–4 weeks). In general, expect at least two weeks for germination.
- Plant seeds 1/2 to 3/4 inches deep.
- Thin to 2–4 inch spacing. When thinning, it's recommended to snip off unwanted seedlings rather than pulling to avoid disturbing the roots of remaining plants.
- Mound soil at base of plant to prevent greening of the root shoulders.
- Cultural requirements are very similar to those of carrots.
