Celeriac needs a long growing season. I grew them for the first time last year and it was possibly October or later before they were ready to start picking. The top leaves grew but the edible part seemed to take forever to swell. They did evetually grow slightly smaller to those bought in supermarkets before I started to harvest them.
Sowed them mid April this year, in modules and the seedlings are still only just over a couple of inches tall with roots just begining to poke through the bottom of the modules but looking healthy.
They were slow to germinate but me thinks they are a veg well worth growing, harvested at a time when very little else is available.
Good luck, patience is a virtue
