I suspect then that my lack of berries is due to my lack of watering, since we got our canes from the same place at the same time. Still, next year's canes are starting to pop up now, so I'll try to be better at watering next spring.

(No problem, I've been really busy too! I've been doing a lot of travelling around London recently but not been at your end — will let you know when I am, in case you're free to meet up,)
