[quote="NMoasis"]1) <SNIP>... but their canopies do spread horizontally and in my opinion are most attractive when allowed to develop multiple trunks — and those trunks might bump into your fence ...
2) <SNIP>...That can be somewhat controlled with early pruning.
3) <SNIP>... Also go out to the proposed location with a measuring tape and measure the mature spread (25' to 35' depending on source) to see if there is adequate space, taking low angled trunks into account. One of the most common home landscaping mistakes is planting young trees where they eventually will be too crowded (to other trees, structures, fences, buildings, etc). Do believe what the label says about the mature dimensions!
1: Amen.
2) Emphasis on early.
3) Extra-special-secret Double Amen. To be clear (and probably a little overly emphatic) this does not mean you need to plant the tree 25 feet from your fence. If you imagine looking down on the mature tree and then picture a 25' circumference with its trunk roughly central you can judge where to plant it so that it has room to grow, be cared for and doesn't create a problem for your neighbors.
