Check these first

  1. Evaluate the amount of light the plant receives daily.
  2. Check the soil moisture to ensure it is not drying out too much.
  3. Observe the plant for any signs of new growth.

Likely causes

  1. Insufficient light

    Most likely

    How to tell: The plant looks stretched out and pale, with no signs of flower buds forming.

    What to do: Move the plant to a brighter location that receives plenty of bright, indirect light. If indoors, a south or east facing window is usually best.

  2. Inconsistent watering

    Possible

    How to tell: The plant is stressed from drying out, causing it to prioritize survival over flower production.

    What to do: Stick to a strict watering schedule every 2 to 4 days. Ensure the soil stays evenly moist so the plant has the energy to bloom.
