Frequently Asked Questions

How do I manage powdery mildew or downy mildew on Raphanus sativus (scarlet globe radish)?

Watch for pale, dusty patches (powdery mildew) or grayish/fuzzy growth with leaf yellowing (downy mildew), especially in humid, crowded beds. Improve airflow by thinning to about 1–2 in (2.5–5 cm) between plants and water at the soil line so leaves stay dry; remove heavily affected leaves. If conditions stay wet, use a labeled fungicide suitable for edible brassicas and follow the label interval before harvesting.

How often should I water scarlet globe radish during active root growth to avoid splitting or woody roots?

Keep the top 1–2 in (2.5–5 cm) of soil consistently moist but not soggy from when seeds germinate until harvest. In most home gardens, that typically means light watering 1–2 times per week, with more frequent small waterings during hot or windy weather; aim for steady moisture to prevent cracking. If you notice radishes getting tough or bitter, increase the regularity of watering rather than soaking once.

When are scarlet globe radishes (Raphanus sativus) ready to harvest?

Harvest in about 25 days when the roots are fully rounded and reach roughly 1–1.5 in (2.5–4 cm) across and feel firm. Don’t leave them in the ground after they size up—overgrown radishes of this type get pithy and sharper in flavor. Check a couple plants early, then harvest the rest promptly at the same root size.
