I asked the gardening mods before moving the question, as I think you will most likely not get an answer here. They agreed that it would fit their site, So no, I don't think it will be moved back.


Normal users can only vote to migrate to sites which have graduated, but moderators can. Out of your examples, all the sites are in Beta except Chemistry.SE, so I think it could be added but there is also a close reason that states "General chemistry questions are off topic...." and redirects the OP to Chem.SE A similar question was also asked before.
