What’s wrong with my orchid?

Bud Drop
There are many reasons why buds fall off before flowering:

Under or over watering.

Temperature extremes and rapid temperature changes (heating vents, air conditioning blowing directly on the plant).

Fumes from natural gas leaks, paint, other chemicals.

Ethylene – high producers are apple, avocado, peach, pear, plum, melons, figs, and tomatoes.

Low humidity.

Genetics.

Aphids, thrips and some mites.

Changing growing location. If you want to change a plant’s location so that it will be enjoyed, wait until the flower opens first.
