I have a "patch" of blueberries that are about 10 feet tall, maybe 
higher, and about 15x15 in area.  The area used to be 20x15, but part of 
the 'patch' has died.  The shoots are coming up thick, and I think this 
is contributing to the die off.
Int he past, we usually just prune out the dead wood and leave the rest. 
 Once or twice in 8 years, we have taken the hedgeclippers and hedged 
back the top growth.
My question is this.. other than berry size the following year, how does 
hard pruning/hedging back help or hinder the shrub?
