Plant
Direct sow every 2 weeks. Fastest crop in the garden — ready in 4 weeks.
Care
Thin ruthlessly for good bulbs. Consistent water keeps radishes crisp; drought makes them woody and hot.
Harvest
Pull when quarter-sized; leave in longer and they get pithy.
Fresh only. Can be quick-pickled for tacos and slaws.
