It’s important to understand that planting trees must be done in the right places, in the right way and with someone to maintain the trees.
Of course, you can plant trees in your own yard or in your neighborhood or even at your school. Research which species grow well in your climate. Look around and see which species are already doing well in your community.
Find local, regional or organizations in your state or - State government agencies - that are working on planting more trees. We found two groups near where we live in Maryland by searching keywords like ‘planting trees near me’.
