This item may be out of season or currently out of stock. Please check back.

Description: If you are familiar with celeriac, you will know that it is a long-storing bulbous veggie with a mild celery flavour and that it is used for roasting, mashing, and grating into salads such as coleslaw. If you aren't familiar, try it! Mars features upright plants and large, uniform roots.  

Pack size: ~ 50 seeds

Latin Name: Apium graveolens
Main Uses: Culinary
Days to Maturity: 95 days
Exposure: Full sun
Certified Organic: USDA Certified Organic

Germination: 14 - 21 days, depending on soil temperature. The ideal temperature is 16 - 21º C.
Sowing indoors: Sow seeds 10 - 12 weeks before planting out date. Since this crop develops slowly over a long season, it is important to start Celeriac indoors and early. Apply Sea Magic from the first watering. From the second set of true leaves to the time of transplanting, alternate between Sea Magic and seed-starting fertilizer (such as Evolve) once per week. 
Planting Depth: 0.3 cm (1/8")
Seed Spacing: Sow thickly in open flats, then transplant individual seedlings to plug cells once the second set of true leaves has emerged. 
Planting Out: Celeriac bolts when exposed to cool spring weather, so transplant outdoors only after spring/early summer temperatures have stabilized and there is no chance of frost. It is recommended to withhold water for one week before transplanting outdoors, as a hardening-off technique (since exposure to cool temps is not a good idea early in the season).
Plant Spacing: Space transplants 37 cm (16") -  45 cm (18") apart; spacing will significantly impact the size of the bulbs.
Outdoors: Not well suited to direct seeding

Fertilizing (Containers): Add up to 30% quality compost or Sea Soil to the potting mix. Fertilize regularly with an all-purpose balanced organic fertilizer.

Growing in Mixed Planters: Not well-suited for mixed planters.
