hi, you can split them into individual cloves and plant them 6-9" apart and then you should havest more bulbs in late summer. [i think thats when you lift them, some one will correct me if i 'm wrong]

They like a period of cold weather, so we plant ours in January - or the previous October - then harvest in August/September or - if planted the year before - in June/July. Then treat like onions with a period of drying before using.

I planted mine about 2 weeks ago, and they are shooting up - although now I'm confused when to dig them up.

But yes, split the cloves. I didn't know how to do it last year and planted the whole bulb together, doh!
