Portland is home to the amazing Friends of Trees which is helping to make every neighborhood in Portland greener through volunteer-led tree plantings. FOT also passes on a huge cost savings to residents that want to add trees to their landscapes. As a resident of Portland, you can purchase an incredibly inexpensive tree through FOT ($25-$75), and they will deliver, plant and check up on your tree. This month I participated in a bicycle tree planting where a crew of cyclists loaded, carried and delivered trees to planting sites by bike.
Many communities offer low-cost tree options, check out the Alliance for Community Trees’ list of tree organizations in your state.
