Why are some columns showing "—"?
Start Indoors shows "—" because Daikon is typically direct sown outdoors rather than started indoors. It germinates quickly and doesn't transplant well.
Transplant shows "—" because Daikon is best direct sown where it will grow. Transplanting can disturb the roots and slow growth.
