Hello.
You really should not be hand-drawing outlines of trees' canopies and deleting tree nodes.
That's called https://wiki.openstreetmap.org/wiki/Tagging_for_the_renderer and that's inappropriate.
Tree canopies change as trees grow, with seasons as they lose and gain leaves and as their branches break or get trimmed. So your mapping becomes inaccurate with each season. However, trees themselves remain where their nodes are.
