Growing Conditions
Warm-season root crop needing warm soil and a long season; frost-sensitive.
Sources: UF/IFAS Extension — Vegetable Production Handbook of Florida · RDA Nongsaro (Rural Development Administration, Korea) · reviewed 2026-08
Irrigation
Even moisture early for root set; reduce late to avoid cracking and improve storage. Fairly drought-tolerant, but even water lifts yield.

Water Quality
Relatively salt-tolerant, but still manage sodium; even moisture shapes uniform roots.

Soil
Loose, well-drained sandy loam, pH 5.5–6.5; compaction distorts roots.

Fertilization
Go easy on nitrogen (excess grows vines, not roots) and keep potassium adequate for root bulking.
