Congregations Needed to Plant Trees in Montgomery & Prince George's Counties Got Grass? Plant FREE trees instead. Through Trees for Sacred Places you can have a BIG impact on your environment, host a GREAT community building and beautifying event on any faith owned property in Montgomery & Prince George's counties and throughout Maryland that can accommodate 60+ trees. If there isn't enough space available you can team up with another congregation. Don't own your property or have no free space? We can put a team of your volunteers to work.
