Growing & Seed Saving Tips

From Adaptive Seeds:

Direct sow ¼” deep, March through September in rows that are 1’ apart. Germination in 5-7 days. Thin to 1” by eating young plants. For mild flavor and to avoid pithiness in bunching radishes, eat before they reach 2” across. Large rooted radish types can be eaten at any size.

Seed Saving

Collect seeds from 20 or more plants (to avoid inbreeding) in the second year when seeds have dried down, usually in July. Cut seed heads, place on tarp, let dry a few more days, then dance to free seed. Collect seeds and winnow to clean. Isolate from other Raphanus sativus by 1 mile.
