Arugula Plant Care

Arugula (Eruca sativa) belongs to the Brassicaceae family within the Eruca genus. Arugula is also known as Rocket, Roquette, Salad Rocket.

Arugula displays a compact rosette growth habit, reaching up to 0.5 inches tall with a spread of approximately 0.5 inches. Arugula produces small white flowers in clusters.

Leaf size: approximately 2 inches.

Eruca sativa requires watering every 3–5 days. Allow the top layer of soil to dry between waterings to prevent root rot. Reduce watering frequency during winter when growth slows.

Arugula thrives in full sun to partial shade light conditions. The optimal light range is 2000–5000 lux. Avoid placing Arugula in direct, harsh sunlight for extended periods, as this can scorch the foliage.

Eruca sativa grows best at temperatures between 50°F and 75°F. Arugula prefers humidity levels of 40–70%.

Well-draining, fertile loamy soil with a pH range of 6.0-7.5. Good drainage is essential for Arugula to prevent waterlogging, which leads to root rot and fungal issues.

Transplant seedlings once they have 4-6 true leaves. Choose a pot one size larger than the current container, and ensure it has drainage holes to allow excess water to escape.

Arugula can be propagated through seeds.

Arugula is susceptible to aphids, flea beetles, cabbage worms. Inspect the foliage regularly, especially along leaf undersides and stems. Treat infestations promptly with insecticidal soap or neem oil to prevent spread.

Arugula grows outdoors in USDA Zone 12a. In cooler regions, grow Arugula as a houseplant or bring it indoors before the first frost.
