Thanks for the link Manda!
Most of ours have shed leaves and have no pods on them, but one or two still have good growth and one in particular has pods still on it and seems quite happy, of the 4 that are flowering, 2 were cut back, 1 died back naturally before starting to grow again, and another is still in bushy leaf, after not flowering through the summer, and all seem to be doing fine, so we'll see what happens!
