I have a Shower tree in front of my house. It was put in about 4-5 years ago my the HOA. There are identical trees in front of every house on the block. It is aprox 20' tall. I think the height is fine. All the trees on the block are much fuller....way more branches and leaves. The tree has a band at the base an 2 bricks on each side. I assume this was to keep it stable when it was very young. When I moved in 3 years ago it still had sticks on each side and string to hold it in place. Is there anything I can do to help this tree along? I am jealous of the neighbors trees that provide a lot of shade.
