Actually.....according to the experts like the person below, Autumn is the best time http://karmahappytoes.org/bruggard.aspx
Ah yes, regional differences. In Ecuador we cut in Spring/Summer (the dry season) because the plant is less active and the cut is less likely to cause it damage; I assume it's similar in Australia, where Edleigh is from. However, for y'all up in Canada, Autumn will be a better idea.
