Gum tree

Eucalyptus fasciculosa is a bit twisty, but it looks to me like most trees -- it generally grows up. This poor tree has been "topped" and trimmed repeatedly to look like this. In California, if a licensed arborist "tops" a tree, he/she can lose their license because it's illegal.

Do you think..the tree is twisted due to power line and trimming...
I think Eucalyptus fasciculosa species is genetically like this..

This poor tree was planted in the wrong place (under power lines), and has been trimmed over and over again, only leaving branches that don't interfere with the lines. This is such a great object lesson on tree planting; plant lots of trees (especially fruit trees), but first LOOK UP and see what's above, and look down and make sure you're not planting over a water pipe (which the tree will invade). OK, off my soap-box now.
