So, here I am having a look at the task in hand; actually, I am well into it at this stage. I have not attempted to prune and shape such a large tree before. It took several days to think out the best way to approach it. Some branches were broken or had spit under the weight of foliage. It seemed that the bottom third of the tree was desperate for sunlight with branches stretching out and criscrossing in the interior of the tree. I figured that some branches could be retrained to fill gaps resulting from the removal of large broken branches. Removing these brances enabled me to enter the tree to clean out the old, dead wood.
