How to Get a Phalaenopsis to Bloom

Put the orchid into a 3-inch clear pot. The pot should be large enough to just accommodate the roots, but they shouldn't be completely smashed. If the roots of the phal are too squished, use a larger pot.

Cut away any broken or rotted roots and leaves. If you are planting the phalaenopsis for the first time, there may not be any to remove, in which case skip this step. But if you are repotting the orchid because it is not blooming, then it's vital to cut off rotted roots and leaves just above the healthy tissue or rot.

Fill the pot with sphagnum peat moss, which is a medium that will retain moisture and provide the proper aeration for the roots. If you have an orchid that is not blooming, it could be because the medium was lacking these qualities.

Move the orchid to a dark, cool room and leave it there for two days. This will reduce its stress as it gets used to the new container. After two days, move it back into a warm, bright room and place it in a location out of the path of direct sunlight. Ideally, the room's humidity levels should be between 50 percent and 80 percent. If the room is too dry, you must use a humidifier to raise the humidity or the orchid will not bloom.

Water your orchid regularly so that the roots and medium are moist but not wet. Never allow the roots to dry out completely between watering. During warm months, you may need to water once every two or three days, whereas in the winter, you can reduce watering to once every 10 days.

Fertilize your phal with a well-balanced 20-20-20 fertilizer. Use 3/4 teaspoon of fertilizer per 1 gallon of salt-free water. In the summer, fertilize each time you water the orchid; when temperatures drop in the fall and winter, reduce the application to once every third watering.
