When should I Transplant a maple seedling?

Hi. I have a maple seedling that is 17 1/2 inces high in a 12inc diamater pot and I was wondering when I should transplant it in to ground.

Thanks for writing. You can generally transplant maples into the ground anytime after they have at least five sets of leaves --- so yours should be perfectly fine to go in the ground.
