The Basics
When to plant
Direct seed in February to April, possibly May, or September
Harvest window
- Harvest when the roots reach 1-inch diameter at the top.
- Expect 90 to 120 days to maturity.
- Flavor is best when the mature plants are exposed to cool weather for 2 to 4 weeks, which encourages the starches in the roots to convert to sugars.
- Loosen soil with a digging fork before pulling roots.
Care overview
- Soil temperature should be at least 50ºF for germination. Seeds are very slow to sprout at that temperature (3 to 4 weeks). In general, expect at least two weeks for germination.
- Plant seeds ½ to ¾ inches deep.
- Thin to 2 to 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 the base of the plant to prevent greening of the root shoulders.
- Cultural requirements are very similar to those of carrots.
