I have grown celeriac successfully at Caboolture and Morayfield. It needs a rich moist soil and some mulch around the plants. I strike them from seed in a pot with seed mix, just under the surface and keep moist. I sow them in April though I am not sure if it is the tight time. They take a long time to grow, being biennial. Never let them dry out though. And they do not like wet feet in the heat. Also, when the bulbs are big enough and start sprouting leaves, when big enough, they can be pulled off and replanted. The seeds can be good on the Net. Happy growing!
