David, usual time is Spring (I think) but on the other hand I have heard it is better to do this when plant is dormant. Anyway plant with crown about 2 to 3 inches below surface and about 3 feet apart. In saying that I put in new plants last year end Sept/early October they are about 2 feet apart - all wrong but they have survived. Didn't really pick any this year as it is virtually their first year.
I put bone mean on when the leaves died back and will fertilise in spring. Keep very well watered.
