I moved into a newly built house in spring of 2003 on a new crescent with 7 other new houses. In 2004, the city planted small maple trees on all of our front lawns + 3 in the middle part of the crescent.

Since then, it has been impressive how quick most of the trees have grown and filled out. I have 2 in front of my house (one on each side) and they are both the slowest to grow??? The one on the left suddenly took off this summer and is now starting to grow and fill out, at a nice rate, altough it is still smaller then the others on the crescent.

The one on the right side of my house, has hardly grown since being planted. It doesent look unhealthy because all of the leaves are out and they look fine, it is just ridiculously smaller then the others (it is embarassing) Here are a few reasons that I believe can affect this, but I really dont think these are responsible:

-French drain: When i got my driveway done in uni-stone, the landscapers re-directed one of my gutters with a french drain bringing the gutter contents underground near the tree in question. In their opinion, more water would be excellent for the tree.

-Sunlight: The tree in question seems to be in an area that gets less sunlight due to positioning of the houses around and the shadow that they cast.

-Quality of soil: THese are new houses that they built in 2003 and they obvioulsy backfilled some of the lots to even it out - for this reason i question the quality of the soil. That being said - this would also apply to all the other trees that are doing well + my grass and flower bed under this tree are doing very well.

Should I call the city? What do i do and what can I expect?

Thanks!
