Roquette Arugula Seeds

Start sowing Arugula seeds directly outdoors, about 1/4 inch deep and 3–6 inches apart. Rows around 10 inches apart make harvesting easier, especially if you plan to cut baby greens often. Soil needs to be at least 60°F for germination, and sprouts can show up in as little as 5 days, though some batches take up to 21. For a continuous harvest instead of one flush, sow new seeds every 2–3 weeks.

Roquette handles full sun, but partial shade helps a lot once weather starts warming up. Heat pushes the plant toward flowering, and once that happens the leaves get stronger and more bitter. Use moist, well-drained soil, because soggy ground slows root growth. It would be helpful to mulch to hold moisture and cut weed pressure.

Harvest outer leaves when plants reach about 2–3 inches, and cut above the soil so the center keeps growing. Baby greens are ready in roughly 2–3 weeks, mature leaves follow later, and the edible flowers can be used as a garnish when plants start to bloom. Protect plants from heavy frost, and don’t let the patch dry out if you want repeated cuts. After harvest, rinse and dry the greens, then refrigerate and use within 6 days for the best texture.
