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

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.
