The Q&A Archives: Roots Of Star Pine (araucaria Heterophyllia'monia")

Question: I'm interested in planting a star pine at my house. Can I plant it safely near my house or block wall? I don't want the roots to eventually crack the wall or foundation.

Thank you.

Answer: Tree roots typically extend out from the trunk about one to one and one-half times the diameter of the canopy of the tree. There are some exceptions, but Araucaria araucana (Monkey Puzzle Tree or Star Pine) roots seem to follow that general rule. Your tree will eventually grow to 30' wide. With this in mind, try to keep it a reasonable distance away from your house so you won't have problems when it matures.
