Growing Radish in Australia: The Complete Guide
Radish is an easy root vegetable to grow, needing full–part sun with consistent watering.
We get asked about radish often enough that it's worth setting out the full picture here, beyond what fits on our printable card.
Fast succession sowing
Radishes mature so quickly that a thick sowing needs thinning within days, and a new row can go in every couple of weeks for a steady supply.
Planting Radish
Method — direct sow thinly, little and often for a continuous harvest. Soil — light, loose, well-drained. Timing — sow year-round in mild zones; avoid the height of summer heat, which causes bolting.
Ongoing Care
Worth paying attention to:
- Thin early to avoid stunted, misshapen roots.
- Keep soil evenly moist — dry spells make roots hot and woody.
- Harvest promptly; radishes turn pithy if left too long.
- Succession sow every 2 weeks for continuous crops.
Common Problems
Keep these points in mind:
- Bolting — heat or stress triggers flowering; sow in cooler months.
- Flea beetle — small holes in leaves; net young plants.
- Splitting — irregular watering.
- Woody texture — left in the ground too long.
Picking and Keeping Your Harvest
Signs — shoulders visible at soil surface, golf-ball sized for most varieties. Method — pull gently by the leaves. Curing — none needed. Storage — fridge crisper, 1–2 weeks; remove tops first.
