Some of it is due to wanting to feel secluded. A family to the south of me and an older couple to the west of me are beyond trees and bushes. The obnoxious building supply store to the north of me is blocked by the barrier of thuja giant evergreen trees I planted years ago. The east is open – well, fairly open; it’s sometimes blocked by railroad cars on the tracks east of the house. Two tall evergreen trees and an adolescent maple tree give me some blockage.
But, another reason for the overgrowth comes from a love of birds.
