We have evergreen trees that are approx. 55 feet tall. I am not sure the name of this type of evergreen, but is has short needles and the branches fall like a canopy and produce very small pinecones. Next door to our property they are intending to build right next to our property line where the trees are and we are concerned about damage to their root system. We have been here for 30 plus years and love our trees. The questions are: (a) how far does the root system extend?; (b) what can be done to protect the root system? (c) if they dig so close to the trees would it be likely that they will die?
The area the new trees would be planted face north, they get some early morning light and afternoon light. Not sure about the soil, but there are scattered trees in this area already but not as a border, so there are quite a bit of root system in the area, but the new trees should be planted a couple of feet away from the existing trees. The trees would be along the back of the lot and our lot is approx 63 ft wide. Also, if we would request 2 lines of trees for privacy/noise levels, do you think that is feasible or how far do such big trees need to survive?
One other question I have is if we want to plant additional trees to line the property line, are there fast growing columnar evergreens for privacy that we can plant or what type of tree could we plant for privacy as they are building a 3 storey, 36 foot tall building right beside our property line which apparently will be 40 foot wide.
