This is off of Bennie Simpson's site,

Many other websites state it is a slow grower. It grows better in wetter
areas. Its taprrot is twice as long as its height. You prob have great
soil and a high water table. You also may have over-fertized it
somewhat.

I'm sure some of this ng's arborists have some feedback for you.
