My Gardenia is blooming... finally

Bought this pot of gardenia from the pasar malam like six months ago.  It grows well and the leaves look healthy.
There are like 5 to 6 buds every time. However the buds drop off before they bloom.

Then I planted it to a bigger pot, water twice daily and heavy feed with fertilizer. It BLOOMS finally, hope the other buds bloom soon.  I count the number of buds daily, there are altogether 18 buds lol.
