Large growth rate changes in a Norway Spruce.
A Norway Spruce planted as about a 9 footer in November 2005 grew 6 inches in 2006 (and had multiple little purple cones in early spring which made me think it might be an Acrocona). This year, 2007, the tree grew 18+ inches together with foot long candles all over - but had no cones at all. Question - will the tree look "unbalanced" in the future with such a large discrepency in the structure of the branches that will develop over time? Should I trim the leader and candles back to a say 6 inches to make the tree more balanced and encourage it to become bushy and stronger?
BTW my theory is that the tree settled in nicely over 2006 as it was well watered and was planted in excellent "woodland" type soil, and so grew much more than when under sever stress the prior year - when it would have been stressed from being uprooted etc. This also ties in with the theory that animals and plants under stress tend to try to propagate more.
