Frequently Asked Questions

Bronze Arrow — what do I do if my plants get downy mildew or leaf spots?

Watch for pale yellow patches on top leaves and a gray-purple fuzzy growth on the underside, which is common on Bronze Arrow in cool, humid weather. Remove and discard badly infected leaves, improve airflow by thinning, and avoid wetting the foliage when watering. If it’s spreading, spray a labeled copper-based fungicide and repeat according to the label every 7–10 days until new growth is clean.

How often should I water Bronze Arrow during the main growing phase (around weeks 3–7)?

Keep the soil evenly moist but not soggy: aim for top 1–2 inches to dry slightly between waterings, then water deeply. In part-sun beds, this is often about 1 inch of water per week total (more if it’s hot/windy, less if mornings stay cool and damp). Use mulch to prevent rapid drying, and stop short of standing water to reduce crown and root issues.

How can I tell when Bronze Arrow is ready to harvest at about 52 days?

Harvest when the fruits are full size and the color is uniformly bronze-bronze rather than patchy or dull green, and the stems near the fruit start to dry slightly. Check a sample: they should feel firm, with good snap/turgor (not soft or wrinkled). If you’re unsure, wait 2–3 more days—Bronze Arrow is typically best picked when color is even and firmness peaks.

Velvety bronze-green leaves unfurl with a softly ruffled edge and a gentle, sweet snap—an inviting, garden-fresh flavor that feels as luminous as its color. Bronze Arrow forms an airy loose-leaf rosette with tender, spoonable texture, ideal for building abundant salads and vibrant platters, and it also shines when lightly dressed into quick tosses and herb-forward mixes. Grow it for a steady harvest over weeks, with leaves that stay crisp and attractive from first cut to the next.

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

Because it’s bolt-resistant and oakleaf-type, you can transplant for early spring cool weather—aim to set it out right around last frost when nights are still cool but stable.
