Sorry to hear that
Orchids, Daffodils, Tulips, and many other varieties of hardy bulb flowers can often be 'tricked' into thinking it is a certain time of year or into blooming, however, this is not true of plumeria. If you have a single branched cutting, even with the perfect weather, lighting, humidity, and fertilization, it more than likely will not be producing another inflo this year. Hopefully it will cause the plant to branch and offer you more likelihood of blooming next year.
