Hi CC, Kohlrabi don't like the humid weather that is prevalent in Auckland's winter. They don't mind the cool, in Germany you'd plant them in March/April. But they are not doing well in rain. I planted mine late last season (Dec/Jan) and I harvested them around April and they were just perfect. I have two late plants going and will sow again today. Re kids not liking Kohlrabi .. my friends' sons (6 & 8) gobble them raw faster then you'd believe. My sons prefer them fried like a crumbed schnitzel. And my hubby can't get enough of soft, creamed kohlrabi with parsley flakes. This is also what I offered my older son mashed up when we was a toddler and we were still living in Germany. Kids need to try the same thing about 10 times before they eat it and my 8yr old eats broccoli and brussel sprouts and other "strange" stuff ...

I had a supprise when I sowed some "mesclun- simply red" for salad greens late October, and after harvesting young leaves for sald, left the plants to seed, but much to my supprise one of the varities that has gone on to maturity is the Kohlrabi, and I found this site because i was looking for ways to grow it. I will try some of the ways suggested. But as far as germination is concerned, I just scattered the seed, watered well and since I have no idea of how many seeds I sowed, I dont know what the germination rate was. But they are growing well and it is now January.

Do you know if I can sow them now in Auckland? My garden is pretty sheltered and cool but I could also put it in the sun. Is there a shop in Auckland that sells the seeds?

I bought 6 plants marked as Red cabbage at a nursery and planted as cabbage in early Autumn all six survive and turned out to be Kohirabi, they tasted just as nice as the good old Southland swede.

Kohlrabi is one of the staple vegetables in Kashmir (India). In Auckland, I have grown it easily from seeds and seedlings. As children we would love to eat it raw! Often eaten as meat and kohlrabi curry with rice.

I purchased a packet of seed at one of the chain of garden centers through NZ and have only planted them five days ago and they are just showing through. End of a long hot dry summer, going into autumn. Not sure if I should or can put this rider in but they are imported by Niche Imports P.O.Box 8 Ashurst, NZ

My dad grew these when I was kid growing up in Te awamutu.i am now 66 so they are nothing new.they were as big as a turnip and love plenty of compost.mum would peel them like spuds and mash them like potatoes or even roast them with the mutton.us kids just loved them and they were so easy to grow like raddishes

Am I right to say you can grow this vegetable year round going by some of the comments I have read here?
