Plant

Direct sow or transplant. Fast, easy, undervalued.

Care

Consistent water — dry stress makes woody bulbs. Harvest when tennis-ball sized; bigger gets tough.

Harvest

Cut just below the bulb when 2–3" across. Skin peels easily; eat raw or cook like turnip.

Preserve

Best fresh. Can pickle. Freezes poorly.
