Frequently Asked Questions

Why are my Astro Arugula leaves getting tiny holes and sticky residue, and what should I do?

Tiny irregular holes with frass (dark specks) and sometimes sticky residue are common signs of flea beetles on arugula. Use floating row cover over seedlings as soon as you sow (remove only for brief harvesting) and knock adults off with a firm shake onto a tray. If damage is heavy, apply insecticidal soap directly to the undersides of leaves and repeat every 4–5 days until the flares stop.

How often should I water Astro Arugula during its main growing phase?

From sprout through the 30–40 day harvest window, keep soil consistently evenly moist but not soggy—aim for the top 1 inch to feel lightly damp. In part sun, this often means watering about 1–2 times per week, but increase to every 2–3 days during warm spells or windy conditions. Water at the soil level to avoid leaf wetness that can worsen arugula diseases.

How do I tell when Astro Arugula is ready to harvest at 40 days?

Harvest when leaves are about 4–6 inches long and still tender, usually starting around day 25–30 and finishing by day 40. For best flavor, pick the outer leaves first (cut 1–2 inches above the crown) so plants keep producing, or harvest a whole bed when most plants reach the leaf-size target. If leaves start to get very narrow and bolt-like (rapidly elongating stems), harvest immediately or you’ll lose tenderness and get more bitterness.

Astro Arugula greets you with a peppery, vividly green bite—tender leaves that feel silky and crisp, with a lively snap from first harvest to the last. This 40-day performer forms a compact rosette of finely textured foliage, ideal for gardeners who love bold flavor without sacrificing tenderness. Grow Astro Arugula for fresh salads and bright, quick garnishes, or for stirring into sauces and finishing blends where its distinctive zing can shine.

Sowing Tips

Transplant Conditions

Wait until soil reaches 40°F and nights stay above 35°F before moving outdoors. Harden off for 5 days first.

Expert Note

For best flavor and slower bolting, keep soil evenly moist and aim for cool weather (arugula hates sustained summer heat).
