How do you know when the celeriac is ready to harvest?

Harvest celeriac when the stem is 75-100 mm (3-4") across or before a heavy frost is likely.

Would like to try growing celeriac, I live on the Whangaparaoa Pen., Auckland, wonder if it would grow here or if wrong climate? Also, if ok, which variety would grow best here.....am trying to lose weight and read celeriace chips better diet option than potatoes? Many thanks, Ruth.

I live in Warkworth and currently eating those as seeded Spring 2016. Seeds I purchased were Mars from egmont seeds.

If you can grow celery you should have no trouble growing celeriac. Check out your local seed companies for appropriate varieties. Trust this helps.

Good day, I desperately need to buy celeriac seeds to take with me to Namibia. Do you have any knowledge as to where I can buy the seeds in Cape Town, Stellenbosch area? Regards Hannelie

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!

Where in Australia does celeriac grow in?

Celeriac is in the same family as celery and parsley so will grow easily in a temperate climate. you will need to check sowing times.
