Thanks to Adam and the other contributors on this discussion for all this valuable information. I had a fabulous agapanthus as a gift about six years ago which we put in a large terracotta pot, which we moved to next to the kitchen wall and covered each winter. Every winter except this last one, unfortunately! After six wonderful years, the poor thing was well and truly dead, and we spent an hour and a half yesterday hacking out all the roots, it looked like a huge pot of spaghetti! Like you say, where does the compost go?? I felt that we'd been quite wicked so it is good to hear they like to be pot bound. We have bought another one, 'Donau', and hope to have the same success with this one, which we promise to look after. Thanks for the advice about the dead leaves, I was never sure what I should do with them.
