Mars – Organic Celeriac Seed

Organic celeriac seed with NOP-compliant pelleting.
Large, uniform roots with big, healthy plants. Interiors stay firm, even when roots are large. Holds well in the field. Upright plant results in less splash from rain and, hence, less soilborne Septoria blight as well as easier cultivation. Similar to Brilliant. Organically grown. Avg. 10,600 seeds/oz. Packet: 250 seeds.

CULTURE: Celeriac requires a fertile soil with a pH range of 6.0–7.0. Do not let the soil dry out, indoors or out. This crop needs a consistent supply of moisture throughout the season for optimum flavor and yield.
PELLETED SEED: If usingseed, for best results, we recommend consistent soil moisture during the germination period. Pellets are made of inert NOP-compliant materials. Our celery and celeriac pellets are both size 8. seed must be kept cool and dry prior to planting, and should be used within one year of purchase.
GROWING SEEDLINGS: Sow in early March or 10–12 weeks before transplanting outdoors. Sow 6 seeds per inch, 1/8" deep, in 20-row, open flats, or plug trays. Keep soil moist and temperatures 70–75°F (21–24°C) if possible. Seedlings emerge in 2–3 weeks and then temperature can be reduced to 60–70°F (16–21°C).
TRANSPLANTING: When seedlings have 2 true leaves, transplant to 72-cell plug trays. Transplant outdoors in late May to mid-June when weather is warm and settled. Set plants 6–8" apart in rows 24–36" apart. Irrigate to keep soil moist. There is risk of plants bolting to seed if they are set out when daytime temperatures are consistently below 55°F (13°C).
BOLTING: Caused by exposure of young plants to temperatures below 55°F (13°C) for 10 days or more. When hardening plants before transplanting out, reduce water for 7–10 days. Do not harden off celery plants by lowering temperatures!
DISEASES AND PESTS: For leaf blights, rotate crops. Ensure adequate soil calcium and water to prevent black heart. For Celery Mosaic (mottled leaves, twisted stems, dwarfing), control aphids.
HARVEST: Late summer through fall at a 3–5" diameter.
STORAGE: After harvest remove field heat by dunking plants in cold water. Store sound heads/roots at 32°F (0°C) with 98–100% relative humidity. Celeriac will store for 6–8 months. CAUTION: In rare instances contact with the foliage can result in a severe rash. When working with this crop on hot, sunny days, we recommend wearing long sleeves and long pants and washing any exposed skin surfaces as soon as possible after contact.
