Arugula 'Tender'

Family: Brassicaceae Leafy Green

Tender Arugula delivers a vivid, peppery snap with a clean, bright finish—tender leaves that stay pleasantly mild for weeks.

The foliage forms a compact, upright rosette of finely textured, deeply lobed greens, ideal for quick harvests when flavor is at its most lively. Grow it for fresh salads, zesty toppings, and fast-turnaround sautés and pestos where its signature bite shines.

Culinary Notes

Chef's Note

Tender arugula is built for speed: harvest and eat it while the leaves still crunch, because the peppery snap turns dull as it over-softens. Use it where heat or acid hits briefly—its job is a sharp, bright finish, not a cooked-down green.

Best Uses

tossed salads where the leaves stay snappy under vinaigrette
quick sautés—just until wilted—for a peppery sheen (not mush)
blended into pesto for a mustardy, green kick
as a sharp topping on flatbreads and sandwiches to keep the bite intact

Frequently Asked Questions

How do I fix downy mildew or leaf spots on arugula 'Tender'?

Downy mildew on arugula shows as yellow patches on top of the leaf with a gray-purple fuzzy growth on the underside, often after cool, damp weather. Remove and discard the worst leaves, improve airflow, and water at the soil line (not overhead) so foliage stays dry. If it keeps spreading, treat early with a labeled copper-based fungicide and avoid harvesting for the product’s specified interval.

How often should I water arugula 'Tender' during peak growth so it stays tender?

During the ~30-day growing phase, keep the top 1 inch of soil consistently moist—water about 1–2 times per week, more often in part-sun or windy spots. Water enough to soak that top inch, then wait until it’s just slightly dry before watering again to prevent bitter, stressed leaves. If you’re in containers, check daily and water when the top inch dries, since they dry faster than garden beds.

When is arugula 'Tender' ready to harvest, and how do I pick for the best flavor?

Harvest when leaves are 3–6 inches long, typically around 30 days from sowing, before plants bolt. Pick in the morning by snipping outer leaves 1–2 inches above the crown, which lets the center keep producing. If leaves start tasting sharply bitter or the plant shoots upward, harvest immediately or pull and re-sow to keep quality high.
