I think one of the main ways is not to make any sudden environmental changes while a plant is budding. Don't move it. Protect from draughts. Just my two cents.
Sometimes it just happens. I had a Cycnodes Rocky Clough a couple of years ago that developed the prettiest long spike. Then the buds started to develop and when they reached a certain size, they blasted. I was frantic (but I'm the excitable type). I'd heard about the dangers of high humidity at night, so I reduced the humidity by about 10% at night (from 70% to 60%). The rest developed just fine. Coincidence?
