The Basics
When to plant
- Direct seed in the spring February through April, possibly May, or in the fall in September.
- Transplanting is not recommended because it typically results in forked or misshapen roots.
Harvest window
- Harvest when good sized but still tender.
- Can be stored in the ground during the cool season for harvesting as needed.
- If left in the ground too long, they may get woody or bolt (send up a flower stalk).
Care overview
- Prepare soil so it is fine and lump-free to prevent misshapen roots.
- Cover seeds lightly and keep moist.
- Thin to 1 to 2 inches apart.
