First, I wrote potassium chloride.
I meant Potassium chlorate.
Not sure if both will do the job.
Not absolutely sure now, but I think I used 4g in 1/2 gallon of water.
Then sprayed the leaves of the tree with it.
The tree must be dormant when sprayed, no growth happening or recently.
It took about 1-2 months before the flowering began in February.
Don't know if it'll work on related species.
I've seen nothing to make me believe it will.
But then, I haven't been interested in finding out.

We do get dry periods of a week or more, but rarely get true drought periods of a month or more.
The timing varies throughout the year.
I did call, it a seedling.
Chances are it was actually air layered.
The tree has already proven it is mature enough to bloom.
