Dear John,

You asked:

> the end of this summer, before they wake up again?

Once I have the Delphiniums in a pot sized to suit them, I have sometimes 
left them there for a number of years without repotting them. Delphinium 
cardinale needs a much bigger pot (in my experience) than D. hesperium. I 
have noticed they seem to respond to water as to when they start back in 
growth again. Usually I have not forced them into growth, but just waited 
for the rain to wake them up. But I have thought that I might be able to 
extend the blooming season if I started them into growth at different 
times. I think repotting the end of summer or in the fall either one would 
be fine. About half of the ones I have in pots have sprouted and I expect 
the others to appear this month or next. A couple in the ground have 
appeared too, but most of them have not.
