Check these first

  1. Evaluate the light intensity in the current spot.
  2. Check the humidity levels.
  3. Ensure the plant is mature enough to bloom.

Likely causes

  1. Insufficient light

    Most likely

    How to tell: The plant looks healthy but produces only leaves. It needs bright, indirect light to gather enough energy for flowers.

    What to do: Move the plant to a brighter spot with filtered light. Avoid direct sun, which can burn the leaves, but ensure it gets plenty of ambient brightness.

  2. Low humidity

    Possible

    How to tell: The plant is growing slowly and refuses to set buds. This plant requires high humidity to trigger its blooming cycle.

    What to do: Increase the humidity around the plant using a humidifier. Aim for 60 to 80 percent humidity to mimic its natural rainforest habitat.
