Arugula

Family: Brassicaceae Vegetable

Peppery-sweet arugula arrives with a lively, nutty bite and a tender, succulent leaf that feels crisp at first touch.

At about 40 days, this specialty green forms a compact rosette of ruffled, lance-shaped foliage—deeply flavorful enough to stand on its own, yet delicate enough for fresh salads and bright dressings. Grow it for bold garnishes, quick tosses, and vibrant greens that shine in sauces and finishing swirls.

Culinary Notes

Chef's Note

This arugula’s trademark heat lands fast and clean, so dress it light and use it as a finishing green rather than something you simmer. The tender, succulent bite makes it ideal with sharp acid (lemon or vinegar) and salty fat (parmesan or prosciutto) where its peppery edge can actually stand up.

Best Uses

quick salad tosses where the leaves stay crisp under vinaigrette
hot finish on pasta or beans—wilts in seconds without turning mushy
peppery sandwich topper (cold) that cuts through fat

Frequently Asked Questions

What pest or disease most often affects Eruca vesicaria (arugula), and how can I control it?

Arugula in the Brassicaceae family is commonly hit by flea beetles, which cause small shot-holes in leaves. Use row cover until plants are well established, and check undersides of leaves regularly; hand-pick adults early in the infestation. If damage is ongoing, treat with an insecticidal soap and focus sprays on the underside where beetles feed.

How often should I water arugula during its main growing phase?

During the ~40-day grow period, keep the soil consistently moist but not waterlogged to prevent bitterness and leaf toughening. In warm weather, this usually means watering about 1–2 times per week with enough water to wet the top 6 inches, increasing to more frequent watering if the soil dries out in a day or two. Mulch lightly after emergence to slow moisture loss and avoid letting the soil swing from dry to wet.

How can I tell when arugula (Eruca vesicaria) is ready to harvest?

Harvest when leaves are tender and about 3–6 inches long (often around 35–45 days), before the plant bolts. Pick outer leaves first for a cut-and-come-again crop; avoid waiting until the plant forms a flower stalk, because leaves become hotter and more bitter once flowering starts. If you see rapid stem elongation, harvest immediately to salvage usable leaves.
