Eruca vesicaria subsp. sativa
vegetableArugula is a fast, peppery salad green with deeply lobed leaves and a distinctive nutty, mustardy bite that sharpens as the plant ages. A cool-season crop in the cabbage family, it is among the quickest greens to grow, with baby leaves ready in about three weeks and full leaves in 35 to 45 days, and it bolts rapidly once the weather turns hot.

When to Fertilize
Lightly once early
Fertilizer
Nitrogen-rich (fish emulsion)
Direct sow in the cool weather of spring and again in late summer for fall, scattering seed thinly in fertile, moist soil in full sun to part shade. Keep the soil evenly moist for fast, tender growth, and sow small batches every couple of weeks for a steady supply, since heat and long days quickly trigger bolting and make the leaves harshly pungent. Light afternoon shade extends the spring crop.

Cover seedlings with row cover; flea beetles shot-hole the leaves
Draw hoverflies and lacewings with nearby flowers; rinse off colonies
Water in the morning, set traps, and hand-pick after dark
Begin picking outer leaves once they reach a few inches, or cut the whole rosette an inch above the crown for cut-and-come-again regrowth, harvesting in the cool of the morning. Pick young for mild flavor and before the plant bolts, after which the leaves turn bitter and tough; the flowers are also edible and peppery.
Arugula is very low in calories and a good source of vitamins A, C, and K, with folate, calcium, and the glucosinolate compounds typical of cruciferous greens that are studied for their health benefits.
