Growing celeriac

I've had very little success growing celeriac. My best year produced some a bit bigger than a golf ball but the rest have just been a mass of roots with nothing in the middle! I've only tried Prinz. Any advice on growing would be greatly appreciated.

Dear Granny, Celeriac are heavy feeders so they need a good amount of well rotted manure or compost digging in before planting, this also helps to retain moisture that Celeriac so desperately needs to produce good sized roots.
They would also appreciate a liquid feed in the Summer.
I think they are often planted too close together, if you can space them 15inches each way this will greatly help.
You can also trim the lower leaves off from about mid-Juy as this seems to help with bulb formation.

Hello Granny
Celeriac is quite slow growing. It needs an early start so that it is in the ground for a long time - from about now onwards would be a good time to sow. I've sown in modules some years and the plants didn't suffer. It's a bit like celery and should never be allowed to dry out - take special care with the plants in hot dry spells.
How did you grow yours?
Hope this helps.
John

Does this apply to celery too? I have a plot I manured last Autumn and would like to grow my celeriac & celery together.

Dear Colin_m, that plot of ground would suit Celery and Celeriac admirably.

Thanks for replies. John, I started mine off in modules in early March and kept them in an unheated greenhouse until I felt it was too warm then moved them outside and planted them out when they had some true leaves. I can see I've been neglecting them - nothing special in the way of manuring or feeding, and nothing extra in the watering line. Just generally let them get on with it like I do with parsnips. I've got a patch that's had a casual compost heap on it for several years which might be promising. I'll sow some seeds tomorrow, and then give them a bit more attention in summer.
