Do trees get depressed?

Only if they lack community

My dad was very into plants. He had read a book that influenced him into this way of thinking ("The Secret Life of Plants" by Peter Tompkins). He was also extremely good at gardening. Me, on the other hand, I'm terrible at gardening. Part of it is poor planning and inadequate effort (both inherent parts of my behavior, i.e. my brain states), but part of it seems to be how energy metabolizes around me. I radiate destruction.
