How do I move a plant from one garden to another?

To move a planting, go to the edit page for that planting and select a different garden from the dropdown list. When you save the planting it will move itself into the new garden.

If you are a Supporter you can also move plantings between gardens really quickly via the Quick Add milestone box on your dashboard (or via the journal items on your Add Journal page). If you select any of the “move” events (i.e. Transplanted, Moved etc) a dropdown box will appear for you to choose the garden you have moved the planting to. This will log a milestone for the plant and stamp the garden move details into the description – this is currently the fastest way to move between gardens and retain the history of when the move was made.
