CELERIAC - IBIS

 Organic Celeriac Ibis

        100 Seeds Pack   

Ibis is a fast-growing celeriac variety known for its smooth, oval-round root. Its fresh green leaves are medium in length, slightly drooping, and highly resistant to Septoria, making them particularly robust. The small leaf crown simplifies cleaning, and the variety’s strong resistance to bolting allows for early cultivation under protection. Ibis is also an excellent choice for long-term storage.

Celeriac roots vary widely in size, ranging from small to large, but typically measure 10-14 centimetres in diameter. They are globular, slightly flattened, and lopsided in shape. The gnarled corm has a rough, brown, and thick exterior, covered in small rootlets that give it a creviced appearance. Beneath the rugged skin lies crisp, ivory-to-white flesh that is dense and firm. When raw, celeriac root is crunchy, but it softens into a smooth, tender texture when cooked, resembling the consistency of a cooked potato. Its flavour is nutty, earthy, and slightly sweet, with hints of celery and parsley. The plant also produces thin, green stems resembling celery, topped with small, serrated

PLANTING & GROWING

Soaking needs to be done at least a few hours before planting, and preferably overnight. To prevent damping off when starting seeds indoors, it’s essential that you disinfect all of your pots, plastic grow trays, seed cells, and seedling tray covers before you reuse them. 

Can grow in plant containers in your balcony garden or inside near a sunny window. If you don’t have a suitable garden spot, try a container instead. Sow celeriac seeds between February and April, approximately 8–10 weeks before the last spring frost. Seeds are slow to germinate, taking 2–3 weeks, and require consistent warmth. The optimum germination temperature is 20°C (68°F), with a minimum of 18°C (64°F). 

Celeriac needs a soil temperature of at least 15°C (59°F). In warm climates, seeds can be sown directly into the soil in early March. Sow thinly at a depth of 0.5 cm (¼ in), and as seedlings emerge, thin them to 30 cm (1 ft) apart in rows spaced 35 cm (14 in) apart. In cooler regions, sow seeds indoors or in a greenhouse/cold frame. Use small pots (7.5 cm / 3 in) filled with fresh multi-purpose compost. Sow two seeds per pot in early March and cover them with a thin layer of fine vermiculite. Protect seedlings from slugs, which may damage the young plants. Once seedlings emerge, thin to retain the stronger plant.

Transplant seedlings to their final positions from mid-May, once the danger of frost has passed. Acclimatize them to outdoor conditions for 1–2 weeks before planting. Ensure the crown of each seedling sits slightly above the soil surface to prevent rotting. Water gently and frequently during the first week to help establish roots, avoiding soil accumulation over the crown.

For companion planting, good choices include lettuce, spinach, and peas. Avoid planting near squash, cucumbers, pumpkins, celery, or carrots to prevent shared pests and diseases.

To maintain healthy crops, do not plant celeriac in the same location for at least three years.
