The Basics
Arugula grows best in the cool season, from August through May. Plants may bolt quickly, especially during warm spells. Succession plant to ensure a continuous supply of young, tender leaves.
When to plant
- Direct seed: March–May, August–October; possibly February, June, and November
- Transplant: February–May, September–October; possibly June, August, and November
- If growing your own seedlings, start the seeds 4 weeks before you want to plant
Harvest window
- Individual leaves are ready to pick 6–7 weeks after germination. Picking outer leaves regularly will keep the plant producing until it starts to flower.
- Younger plants have milder tasting leaves. If you prefer the milder leaves, seed new plants every couple of weeks to maintain a continuous supply of young plants.
Care overview
- Plants prefer cool temperatures, so they will perform best when planted in early spring or late fall. Withstands light frosts.
- Will resow if allowed to go to seed.
