Additional Information

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.


CULTURE: SPRING-PLANTED CROPS: Sow 2 seeds per cell, 1/4" deep in 72-cell plug trays. If possible, keep temperatures at 75-85°F (24-30°C) until germination and then reduce air temperature to 60-70°F (16-21°C). Transplant out in 3-5 weeks, around the last frost date (see BOLTING below), taking care not to disturb roots; water-in plants.
SUMMER/FALL-PLANTED CROPS: Start seedlings as described above in mid to late June or direct seed from late May to mid-July as described below.
DIRECT SEEDING: Sow 3-4 seeds every 12-18" (thin to one plant) in rows 18-30" apart from late May to mid July.
BOLTING: This crop performs best in the gradually decreasing day length and cooler temperatures of late summer, but can be grown successfully in the spring if careful attention is paid to prevent bolting. For spring and early summer transplanted crops, be sure to wait until the last frost date to transplant or direct seed the crop. Young plants may bolt prematurely to seed if they are exposed to frost or over a week of sub 50°F/10°C nights.
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. For seed lots received after August 2015, individual seed lots have been tested free of black leg in a sample of 1,000 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.
HARVEST: Cut when heads are very firm.
DAYS TO MATURITY: From transplanting; add 14-21 days for direct seeding.
AVG. PRECISION SEEDING RATE: 1,000 seeds/333', 5M/1,666', 66M/acre at 3 seeds/ft. in rows 2' apart.
TRANSPLANTS: Avg. 700 plants/1,000 seeds.
SEED SPECS: SEEDS/LB.: Avg. 136,800.
PACKET: 100 seeds, sows 33'.
