Growing Tips
Plant from root cuttings (pencil-thick, 20-30 cm) set at 45-degree angles in early spring.
Lift and strip lateral roots twice during the season to produce a single straight marketable taproot.
Harvest after first hard frost -- cold exposure converts starches to sugars and improves pungency.
