Question
Im an architecture student and I'm working on a
(theoretical) project involving a pre-existing tree. Its a
deciduous tree with a 20m canopy - I was wondering what
might be the tightest space I could put it in (if I were to
enclose it in a courtyard, for example). The roof is low, so
the canopy would clear it, but is it a problem for the trunk
to be mostly separated from the canopy if its coming out of
a small space?
Thank you for any elucidation

Answer
Andrea, For optimal tree health you should provide a mulch ring around the tree as large as the crown, so 20m. However, it is rare for the average person to give this much room for a tree, especially street trees. I would say for the purpose of your project, give the tree as much room as possible while still fitting into your plan. In regards to to the trunk being separated from the canopy, this is a non issue because they are not separated at all. The canopy is connected to the trunk and roots via a vascular system located within the trunk just below the bark. Good Luck on your project!
