Common Questions
Radish questions
What zones can Radish grow in?
Radish is hardy in USDA Zones 4–10. Inside that range it survives winter in the ground; outside it, grow it as an annual or a container plant you protect.
Is Radish deer resistant?
Not reliably. Deer may browse Radish, especially tender spring growth — plan on repellents or fencing where pressure is high.
When does Radish bloom?
Radish typically blooms in early summer through late summer. Exact timing shifts a week or two with your zone — Sow's bloom calendar maps it to your garden.
Does Radish need full sun?
Radish does best in full sun to part shade. In hot climates, afternoon shade keeps blooms fresher longer.
