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. :)

Which is the best way to sow my kohlrabi seeds straight into the garden or planting pots in the sun room? Thanks

It does say plant straight into the garden. A general rule I use is - if a very small/small seed use a pot or seed tray. If seed is bigger then straight into the garden. A small seed (cabbage/lettuce) takes a lot of looking after to get it established - 3-4 weeks. Things like corn/bean/pea seeds will boom. It also depends on the weather also. The hot or cool time of the year.
