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.

How do I grow celeriac successfully in Brisbane? Who are the largest growers of celariac in Australia?

I was sold celeriac seedlings in Ballarat at a market in May - having not tried growing it before I asked how long it would take to mature because we were going away in June up north for winter and was told they would be picked before we left! I was gullible because I have since read that they should be planted out in Nov - Dec not in the guts of winter and frosts! Oh well!!! Have left them in the ground will see whats happened when we return late Sept or early Oct!!

We live near Bendigo. For years i have tried to grow Celeriac but unsuccessfully, first in Scotland and subsequently in Australia. The plants always ran to seed before forming a good root base. Last year i bought beautiful seedlings in June, planted them, they grew fantastically then bolted, I pulled them out. I tried growing from seed but direct sowing has never worked. Growing in a good seed mix did work but then the seedlings struggled and many failed in the ground. However my third attempt last year has resulted in some good sized celeriac which we are eating now. They are just showing signs of bolting though so are all getting lifted this week. They are very sensitive to drought so keep the plants well watered. Watch your plants for any signs of bolting and if they show them, rip them out and start again! I think now is a good time to start some in trays. I cannot find any seed yet this year but there are plants in the garden centres that i would not bother with - they are root bound and sure to bolt. Good luck. Celeriac is such a beautiful vegetable.

What do you mean by 'bolting'?? I am growing celerac in a pot successfully. Planted them in the middle of winter and they are now over 18 inches tall. (End October )

I have been told to transplant celeriacs twice but I never had the opportunity to know at what stage of the growing of the plants I should transplant them. Can you let me know? Thanking you, Charles.

I'm in Melbourne now but moving to Philipnes soon and it's mostly hot and humid there. I'd like to know can I grow celeriac when I get get there. The soil is mostly well draining sandy

I thought I planted celeriac at the right time - May, but now Sept & no bulbs. It's been nice & damp, good drainage with compost pre-dug in, planted in full sun, but cool thru winter. They look like they've had to much nitrogen though I haven't used it. If I added potassium now, how long could I/should I leave them?

If the plants have survived, then leave them as is - they should hopefully start to swell up into bulbs and give you harvestable produce by december/january

I brought my seeds on ebay

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