Hosty Mush has a cottage on a well-treed lot in Northern Manitoba. She keeps her lot in very good condition by fertilizing, pruning, and removing deadwood/broken branches. however, she has a strange habit regarding her little forest. Occasionally, she'll chop down a perfectly healthy tree and put it in a large pot. She waters it and fertilizes it for a short time. Then she grows tired of it and burns it. Could there be any explanation for this strange behaviour?
