I planted a tree in my yard 6 years ago,that has grown really tall, blocking my neighbors's view .?

Since you know that particular variety grows so well for you, is there another area of your yard that one can be planted which won't block anyone's view? If so you could plant a new one in that location, and then take down the current one.

The only other options would be to continue to trim every year, or just let it grow and have an angry neighbor.

Sounds like you are between a rock and a hard place. You like the neighbor and you like the tree. One alternative would be to replace it with one that does not grow so high, or limb some of the lower branches to give him some view back.

Do you know the name of the tree?

Is your neighbor complaining about his view?

I would keep peace with the neighbors and keep trimming it.

Too bad for the neighbor.

Get a pole trimmer for about $30 or so and do it yourself (carefully so you don't injure yourself...the limbs look lighter in the air than when they fall on the ground).

legally you dont have to do anything. it is in your yard. if it is a large nice tree i would let it grow. he can move around view naked women at other angles.

I don't know...which is more important? The tree, or the friendship?

I would hope you choose the friendship.
