The flowering period of a Phalaenopsis can last up to four months, but eventually this time comes to an end and the flowers fall off. This is perfectly normal. The only reason to worry is if all the flowers wilt at the same time.

Why are the flowers falling off?
If all the flowers go limp at the same time or if they even fall off, you can assume that your Phalaenopsis is not feeling well. The reasons for this can be varied and even contradictory. Maybe she got too much water or not enough. Have you fertilized the plant regularly or put it in a different place?
Causes of premature shedding of flowers:
- Change of location after purchase or even at home
- Watering error: watering too much or too little
- too cold location
- too much sun exposure
- waterlogging
- draft
tips
If the roots start to rot due to waterlogging, then only careful and early pruning of the rotten root parts will help.
