Shipping Information & Notes

Rubicon is somewhat larger than Minuet, and should be spaced 18" apart (compared to the 12" spacing suitable for Minuet). It is NOT recommended that customers decrease spacing with the goal of smaller heads, because the heads will not become dense.

For best results, trim heads before storing. They will keep 1-2 months at 32°F/0°C and 95-98% humidity.

Growing Information

Cabbage, Chinese



CULTURE: SPRING-PLANTED CROPS: Use our bolt-resistant varieties. In the greenhouse sow 1-1½" plug trays and transplant out in 3-5 weeks taking care not to disturb roots; water-in plants.
SUMMER-FALL PLANTED CROPS: Sow 3 seeds every 12-18" (thin to 1 plant) in rows 18-30" apart, late May to late July, or grow from transplants as above. Observe sowing dates in variety descriptions.
BOLTING: The crop performs best in the gradually decreasing day length and temperatures of late summer. For spring- and early summer-planted crops, bolt-resistant variety selection is critical. Even the most bolt-resistant varieties may prematurely bolt to seed if young plants are exposed to frost or over a week of sub 50°F (10°C) nights. Wait until about the last frost date or after to direct seed or transplant out, or protect the plants with fabric row covers (See Index).
DISEASE: Practice preventive crop rotation and sanitation. We only stock seed lots that have been tested free of black rot in a sample of 30,000 seeds.
INSECT PESTS: Control flea beetles and cabbage root maggots with floating row covers from day of planting. (See Index).
STORAGE: Heads will store 1-2 months in a near-freezing, humid cooler, or in a root cellar if trimmed and wrapped in newspaper.
DAYS TO MATURITY: From transplanting; add 14-21 days for direct seeding.
