A form of celery which has a swollen root and lower stem. Raise seeds in individual pots and plant out after last frost to give them plenty of time to develop a good root. Grow in a very fertile, rich soil. Water generously.

In cold climates start under glass in late winter/early spring.

I peel and grate the celeriac in then sautee in a skillet for a replacement of potato hash browns.

I want to grow some Celeriac and wonder if the southern heat in the summer will affect its growth. I live in Columbus Georgia and celeriac is not known down here. Also, if I sow in January, will the frost affect it?

Being as Celeriac is a root crop, it can easily handle Winters in Georgia, IMO. I live in Port Angeles, WA, and I grow Celeriac all year around. However, I do use about 4" of Alder wood chips. Works great at keeping everything nice and cozy. :-)

Hi! I live on the east coast of Central Florida and would like to be able to grow celeriac seems to do really well here, so does anyone know if I can grow celriac? Also, do you know if it can be regrown for the seeds?

Yes, I live also on the east coast near Titusville and I grew really big, beautiful celeriac, from seed, organically, in a raised bed last year. I plan to put it in again this week (late Jan). They take what seems like forever to bulb up. But patience is your friend. Good luck!

I'm in Port St John, have you found a variety that does better than others here?
