you can move them now, not the ideal time but not the worst time either. Dig as big as you can, the roots are going to grow more out than down in plumeria. You`ll cut some, there is no way around it but they are tough. Replant, water well and they should do fine.

You might want to provide them with a bit of shade since they are going from shade to sun to prevent burn, a shade cloth over the top, gradually leave it off longer and longer as tolerated until it can be removed.

Water more than you normally would the first couple of weeks to allow roots to be established, unless of course you have some rain. I am assuming it is hot where you live right now. If it is cooler than water less, you don`t want to keep them wet or they will rot.

People take theirs out of the ground every year to store for winter, they replant in spring and the plants do fine. Yours are just skipping the storage.

Tally HO!
