I'd grown successfully celeriac in Caboolture, about 8 metres about the sea level. The bulbs were as big and juicy as any I found in the shops, presumably brought in from the South. They grow quicker but are still biennial. In summer, watch out for soil pests. Spray with weak wettable sulphur(the bulbs, when they start forming).Plant in early spring in punnets and plant out when leaves are formed. keep moist and in well drained rich soil.

Milton have a look at www.edenseeds.com.au that is where I got them, as well as other seeds and they were all viable. I strongly recommend them.

Marinus, Try The Lost Seed, Eden Seeds or Green Harvest. All currently list celeriac seeds for sale. I've bought other seeds from each of these places and have been satisfied with their service and quality.

generally, lots of leaf but no bulb would mean too much nitrogen and not enough potassium. Nitrogen is used for leaf and stem growth, K is essential for fruit and flower formation. grow in soil that has had hungry plants like leafy greens of broccoli grown in it previously, and avoid high nitrogen manures, use well matured compost instead. The parent crops of modern cultivars of celery and celeriac grew in marshes, so make sure soil is deep and moisture holding. All through summer, it will be just leaves but the bulb will swell suddenly in a burst of metabolic resource direction in autumn/ early winter, in order to give itself food stores for the cold season. If temperatures are cool in your winter, you can leave in the ground unitl you need to harvest them.
