Brilliant celeriac seeds are easy to grow and harvest. The big white root has few external markings and grows vigorously. Flavour hovers between a mild celery and parsley and it has the consistency of a potato. Celeriac is surprisingly versatile and makes a fantastic puree that matches well with other root vegetables. Or try dicing some and adding to winter soups. Add some to stir-fries, or sliced thin in a scalloped or gratin dish. Try cutting some raw celeriac thinly in to matchsticks or small cubes, and pickling them in some sweet vinegar. The firm texture of pickled celeriac adds crunch and a bright flavour to salads and stews.

Season & Zone
Season: Cool season
Start indoors early March to the end of May. Optimal soil temperature: 15-24°C (60-75°F). Seeds take up to 20-30 days for germination.
Sow seeds no more than 5mm (¼”) deep, 3 seeds per pot, and thin to the strongest plant.
Ideal pH: 6.0-6.5. Celery is a heavy feeder and needs rich, moist soil. Add compost to soil and apply ¼-½ cup of complete organic fertilizer per 1.5m (5′) of row. Transplant when seedlings are 10-12cm (4-5″) tall, in mid-May to July. Space transplants 30cm (12″) apart in rows at least 45cm (18″) apart. Water frequently. Premature bolting may result from young plants being exposed to temperatures below 13°C (55°F) for several days.
For best flavour and longer storage, water plants the day before harvest. Stalks on the outside of the plant can be harvested at any time. The entire plant may be harvested once the desired size is reached, but the home gardener should leave the plant in the garden and take only what is needed, leaving the root intact. If winter is not too cold, celery will stand in the garden until spring, allowing for light pickings for soups and salads.
In optimal conditions at least 55% of seeds should germinate. Usual seed life: 3 years.
