Jim, are you pruning back the wood every year or two years?  I find it
makes a huge difference in productivity for me.  Also I seem to remember
that you're in zone 3 and wonder if there are hardiness issues going on for
you."

Miekal,
   I grew a named variety of Sambucus nigra that grew 8' tall and was very 
productive...............for two years.  Thereafter they have grown only to 
an unproductive short (2' to 3') bush and are very difficult to destroy, 
resistant even to Round-Up.  I keep digging them up and left over roots 
sprout somewhere else and I dig again.  I've been trying to get rid of them 
for eight years now.
