About this plant
Arugula is a leafy crop with a distinctive peppery flavor that works well in salads. It suits all four zone groups (3-4, 5-6, 7-8, 9-10) as a cool-season annual and grows in full sun to partial shade.
Use moist, fertile, well-draining soil and give frequent, light watering. Gentle watering helps keep the seedbed moist without washing seeds away or flattening small seedlings.
Common beginner failures and fixes
- Seeds dry out before sprouting: Check the seedbed frequently and water lightly to maintain moisture.
- Leaves become too pungent: Pick leaves young and choose the cooler part of the season for planting.
- Seedlings develop tiny leaf holes: Cover the planting with insect mesh and check that its edges stay closed.
- Plants stretch and crowd together: Thin seedlings according to the packet and choose a spot with full sun to partial shade.
Beginner checklist
- Grow as a cool-season annual in your zone group.
- Select full sun to partial shade.
- Prepare moist, fertile, well-draining soil.
- Provide frequent, light watering.
