I too have had trouble with Celeriac. I only managed to get one to grow, the seed just wouldn't germinate. Last year they did germinate but like you nick they had great top growth but nothing underneath. I won't give up though, I will have another go next year because they are a fantastic veg for steaming, roasting, mashing in with potatoes etc. The weather this year just hasn't helped at all, thats what I think it is.
