Who is responsible for trees growing across property line in pa?

In Pennsylvania, property owners are generally responsible for trees that grow across property lines. If a tree's trunk is on one property but its branches or roots extend into another, both property owners may share responsibility for maintenance. If the tree poses a hazard or causes damage, the affected property owner can request that the other owner take action, or they may seek legal remedies. Local ordinances or specific circumstances may further influence responsibility.
