I suppose I'll make do with a low yield this year. I think it was around
April when I potted them.

Once they have finished do they just get left or do you cut them back?
And
if so, do you cut them 'right' back??


No need to cut them back, the leaves will die back brown - but that gives
protection from the frost, so i'd leave them till spring and when new growth
has appeared remove the dead leaves..
