Let it dry out pretty good a few times in a row.
You have to watch it pretty good. Just let it get to the wilting stage before watering.
After a couple of times of this treatment it will think that it's about to kick the bucket and needs propogate itsself buy giving a last hurrah of flowers.
Now the draw back here, is that it may just kill it.
But, on the plus side............ that is the plus side.
One less serissa bonsai.
