Frequently Asked Questions

Why are my arugula leaves developing white powder and how do I stop it? (arugula powdery mildew)

Powdery mildew shows up as a gray-white, floury coating on arugula leaves, often in humid, crowded beds. Remove badly infected leaves, then thin plants so air moves through the row and water only at the soil line (not the foliage). If it keeps spreading, spray with a labeled horticultural sulfur or potassium bicarbonate product, using the label rate and reapplying as directed.

How often should I water arugula 'Rugula' during the main growing phase so it stays tender and doesn’t bolt?

From about germination through harvest, keep the top 1 inch of soil consistently moist but not soggy—typically 1 inch of water per week total, split into 1–2 waterings. In warmer part-sun spots, check daily; water when the soil surface dries but before it crumbles, because drought stress quickly triggers bitterness and early bolting.

How can I tell when arugula 'Rugula' is ready to harvest?

Harvest at about 35–40 days when leaves are 4–6 inches long and still tender, with bright green color and no tough stems. You can do a first “cut-and-come-again” harvest: snip outer leaves 1 inch above the crown, leaving the center to regrow. If leaves get noticeably larger but become sharp-tasting or the plant starts sending up a flowering stalk, harvest immediately or remove to prevent seed-stalk flavor changes.

Peppery and vividly green, Arugula ‘Rugula’ unfurls tender leaves with a bright, piquant snap that feels alive on the palate. Expect a delicate, lacy texture and a naturally upright growth habit that makes harvesting satisfying and consistent at about 40 days. Ideal for fresh salads and quick tosses, it also shines when stirred into sauces for a bold, peppery lift and when pickled for a tangy, aromatic bite.

Sowing Tips

Transplant Conditions

Wait until soil reaches 40°F and nights stay above 30°F before moving outdoors. Harden off for 6 days first.

Expert Note

For long harvests, sow arugula repeatedly every 2–3 weeks and keep it cool (shade in hot spells) to further delay bolting.
