Germination & Seedling
1-2 weeksSeeds sprout within 3-5 days in warm conditions. First true leaves (lobed, characteristic arugula shape) emerge within 1-2 weeks.
Keep soil warm (55-70°F ideal) and consistently moist. Thin seedlings to proper spacing once true leaves appear to reduce crowding.
Vegetative Growth
2-3 weeksPlant develops 4-8 true leaves, establishing a rosette pattern. Leaves are tender, bright green, and gradually become more deeply lobed.
Maintain consistent moisture and keep soil cool in hot weather. Begin harvesting outer leaves once plant has 6+ leaves for continuous picking.
Leaf Development & Harvest Window
1-2 weeksPlant reaches peak tenderness and flavor with full rosette of harvestable leaves. Leaves are most tender and mildest in flavor at this stage.
Harvest outer leaves regularly to encourage more production. Keep soil moist to prevent stress and bolting. Use mulch to keep roots cool.
Mature/Bolting
1+ weeksPlant sends up tall flower stalks with small white or pale yellow four-petaled flowers. Leaves become tougher and significantly more peppery and bitter.
Once bolting begins, harvest remaining leaves quickly. Flowers are edible and have a similar peppery flavor; can be harvested for garnish or salads.
Seed Production
3-4 weeksFlowers fade and are replaced by elongated seed pods. Plant energy goes entirely to seed development; leaves are unsuitable for eating.
Allow select plants to mature fully if saving seeds. Cut entire seed pod clusters when they turn brown and dry them indoors for seed extraction.

Harvest Tips
Begin harvesting outer leaves when plant has 6-8 true leaves (about 3-4 weeks), pinching from the outside to encourage more growth. For full plant harvest, cut 1-2 inches above soil level. Morning harvest yields the most tender, crisp leaves with fullest flavor. Harvest before flowering for mildest taste; flowers and seed pods are also edible. Rocket bolts quickly in hot weather; plant in spring and fall for best quality, or plant succession crops every 2-3 weeks for continuous supply.
