They were a symbol of America’s postwar suburban expansion that embodied the idea of opportunity and peace. They were planted across the United States because of their ability to flourish in poor soil whether it was wet or dry, acidic or alkaline. The opportunistic people who planted these trees had good intentions, but today we are removing more silver maples than any other species.īradford Pear trees are another species that have been widely planted since the 1960s. These trees, on average, can grow up to 60-80 feet tall and 30-50 feet wide and sometimes ever larger. The homeowners in the mid 1900s did consider the function and form, but not the size and definitely not the species characteristics. Their trunks are susceptible to decay and their branches are HIGHLY susceptible to wind, ice and snow loads. Their roots are conflicting with sidewalks and driveways. Fast forward 50 to 70 years and silver maples are wreaking havoc on homeowners and communities. They were looking for that quick shade to help cool their homes. After World War II, homeowners were planting silver maples near their homes. Silver Maples have been a staple in many towns for many years because of their quick shade and rapid growth. We even see homeowners take the proper steps of function, form, size and site conditions, but don’t consider the species characteristics. We often see homeowners choose a tree that provides the proper function and has the proper form, but then don’t consider the site conditions.
