So, that means that once you've mastered the Level 1 tree, and have sufficient Level 2 trees to get mastery (or have it) it pays to delete the mastered trees, so as to get other masteries more quickly? As I read it, otherwise there's a chance you may get unwanted (=already mastered) trees from seedlings. Correct?
