The description of the mending cantrip says:
This spell repairs a single break or tear in an object you touch, such as a broken chain link, two halves of a broken key, a torn cloak, or a leaking wineskin. As long as the break or tear is no larger than 1 foot in any dimension, you mend it, leaving no trace of the former damage.
This spell can physically repair a magic item or construct, but the spell can't restore magic to such an object.
For the purpose of mending, are plants considered to be objects? If a patch of bark falls off of a tree, or a limb or branch, could it be reattached with mending?
I understand that living creatures are unaffected by this cantrip, as they are not objects, which is directly stated by Chris Perkins on Twitter. But, while plants are living, usually, could the cantrip be cast to restore them if they've been damaged?
It could be argued that once the plant has been destroyed, it is now an object. How would still living trees and other plants be ruled?
