Hello Plant Parents!
We have enabled Cloud Support for save games on Plant Therapy. This means you can take your apartment to any other machine you are running steam and continue to play the same apartments.
Important Note: If you have been using multiple machines then you should play from the game you want to keep first to make sure it's the one that gets uploaded to Steam Cloud. If you want to keep separate games on multiple machines then you will need to disable cloud support in the properties page for the game.
Happy Planting!
