Robert Polomski discusses the importance of tree selection and placement in maximizing energy savings from trees. Planting a variety of tree species, such as evergreen and deciduous, allows for not only an aesthetically pleasing landscape but also a more resilient landscape. For example, if one type of tree species dies in a diverse landscape planting, the entire landscape will not be affected as much as a landscape with the same species. Additionally, diverse species can be located in the landscape to maximize heating and cooling effects on structures, as well as providing a windbreak. The video also discusses the importance of maintaining (watering, fertilizing, and pruning) recently planted urban trees through their establishment period (often for the first 10-20 years) to maintain a canopy with a strong branching network .
