quick-pickled rounds for tangy crunch on tacos and grain bowls
grate into a quick quick-cured salad with salt and citrus zest
garnish for color and bite on rich plates like hummus or roast chicken

Frequently Asked Questions

How do I prevent and treat powdery mildew on Raphanus sativus (Red Globe radish)?

Powdery mildew appears as a white, powdery coating on radish leaves, often after humid spells. Remove and discard heavily affected leaves, then improve airflow by thinning plants so leaves aren’t touching. If mildew keeps spreading, spray an approved horticultural fungicide and avoid overhead watering to keep foliage drier.

How often should I water Red Globe radish during the main growth phase to avoid splitting or pithiness?

Water so the top 1–2 in (2.5–5 cm) of soil stays consistently moist, typically about 1 inch (2.5 cm) per week total depending on heat and wind. Start with frequent light watering after sowing until seeds sprout, then keep moisture even—radishes that dry out then get watered heavily are more likely to crack or become pithy. Use a gentle stream to prevent disturbing developing roots.

When is Red Globe radish ready to harvest, and how can I tell without guessing the date?

Harvest when roots are about 1.5–2.5 in (3.5–6 cm) wide and feel firm with a smooth, well-colored surface; Red Globe is often ready in ~25 days. Pull one test radish—if it’s tender and crisp with a mild bite, harvest the rest promptly before roots enlarge and become woody.
