2. Size trees and shrubs to scale. These should be planted in the right scale for the house so that they don’t block windows, doors, and other architectural features on the home’s facade. A large two-story house can handle a redwood, Chinese pistache, sycamore, or scarlet oak, but a one-story cottage is better paired with a flowering cherry, crabapple, or eastern redbud. Too many trees too much shadow and cause potential buyers to worry about maintenance and costs.
