Tree questions split into “what species is this?” and “is this tree healthy / what should I do?”. r/marijuanaenthusiasts is the long-running trees community for woody plants. r/arborists is stronger for care and risk questions and tells posters not to use it as a pure ID board.

- Trees don't belong in pots! Chances are your tree is declining because of an unhealthy root system. Trees require much more space than a standard pot can provide. If you have a tree you're planning on planting…
