Update:

Just been up to the shed to see if my leeks have germinated (they have!  ) and took a look at my raspberry patch on the way back (a very quick look, it's freezing out there!)

I dug up six of my established plants and replaced with new earlier this year; the established ones have just started sprouting from the base, the new ones have got live buds on their single little canes but no signs of shoots from the base yet.
