Could be one of our natives such as Bandicoot which dig down to eat roots of plants.

Hi Phindile I was diagnosed with type 2 diabetes 5 years ago. Yesterday I came across an article about this kohlrabi plant. I also would like to know where to get the seeds of this plant. When I googled earlier I saw that Woolworths sells a bunch of this kohlrabi for R19,99; but like you I prefer to have the seeds so that I could plant it myself in my own garden. Please let me know if you get any positive responses.

HI, I am trying to grow Kohlrabi for the fist time. We live in Newcastle, north of Sydney. I planted the seeds at least a month ago. Lots of leaves but no swelling at the base yet. I was wondering how long it takes to form?

It says 7-10 weeks - give it some time if it is only 1 mth old.

Thanks. I have read elsewhere that it may be too warm here to grow it successfully. I hope not tho as my son has been eagerly looking forward to seeing this rather unusual veggie growing. :)

I live on the Mid North Coast and find no issues growing them up here.

Eden seeds (edenseeds.com.au) have Kohlrabi seeds. I have it currently growing in raised garden beds quite happily so I can't see why it wouldn't grow in foam boxes
