Plumerias do not like water and will go soft if you give them too much. Expect leaf drop and then dormancy, followed by the flowers - enjoy. When leaves are building nicely, then you can water - sparingly. Watch out for mould and similar disease. They are difficult in Uk.

Thanks J . I bought them from a specialist grower,they were strong in leaf and then went into winter dormancy.so i have not had the pleasure yet of that most heady perfume!!!! Guess i need to keep my fingers xxxx that they wont drown!

id be asking if you can bring them threw customs realy to start with .

I'm sorry to say that Plumeria are usually kept as house or conservatory plants in the UK.

NP - yes, you can bring plants back from within the EU

worth a thaught andrew .

Thankyou every one , I guess living on a houseboat could constitute a house? There is no way i will leave them behind, plus i have so many other 'tropical' plants iam loathed to leave eg my papyrus [ 7 foot tall] jasmines [17 foot tall and climbing] and strelitzias. Not to mention my wonderful collection of grasses and callas!!!!! heyho

A houseboat, what an exciting life you do lead. Yes, it's still a house from a plant's point of view, but not with the same amount of space, lol
