Has anyone grown celeriac before or regulary and have any tips on gaining a successful crop?
I've tried growing it for the first time this year and found that although I have some very healthy looking plants, I'm not seeing any real swelling of the root itself! They're still only the size of a small tennis ball.
Apart from Celeriac i've also had problems with beetroot this year with regards to swelling of the roots or lack of as i have found! Everything else is growing great though carrots are a fantastic success and the parsnips are expanding rapidly at the crown, although length wise I wont know till lifting time!
