How do you know when celeriac is ready to harvest? I can't remember how long ago I planted it. At the moment it looks just like immature celery on top. Maybe about 30cm high...

I buy mine from Greeharvest.com.au they are in QLD and ship to WA. Delivery takes while because of quarantine in WA, all seeds so far have been good and viable.

In France they use celeriac in a different (and succulent) way: Thinly grated, raw, just like carrots, and mixed with a mustardy mayonnaise. Delicious, especially next to a green salad or thinly grated carrots.

I bought my seeds from the Italian Gardener. The plants are lush and healthy and I am using the fronds as celery but the root bulbs have not developed (been in ground now 24 weeks). I suspect that the soil was not sufficiently rich in compost etc.

I buy the celeriac bulbs ( with the smaller roots still attached) from the supermarket and allow them to re establish themselves, then I wait for it to go to seed, and in the meantime I am still able to pick the stalks and use them in my cooking. It works for me :)
