I learned a long time ago,the hard way, that most jasmine love water...when mine are outside which is almost all 'Spring and Summer, I put the hose on them as I do with the mandevilla and bougainvillea . I soak them every day if the sun is really hot and they do dry out. All of them are pot bound and I do not intend to transplant them into bigger pots until I must. They seem to thrive in the pot bound 12 inch pots. I sit them around the dog yard and the deck and just take that old hose to them every evening or early morning. Now of course they are in the greenhouse and they do not get as much water in there which could be a problem since they are now so large. I did cut them all back but they grew so much this summer they were monster plants. The Mandevilla is a beautiful houseplant and although not fragrant it is worth looking into. It does get larger than most houseplants but if you are into tropicals it may be worth a try. That is another thread. sorry.
