Christmas cactus · Schlumbergera buckleyi

Why is my Christmas Cactus dropping its flower buds?

Bud drop is frustrating, but it usually happens because the plant is stressed by a sudden change in its environment. Check if you recently moved the plant or if it is sitting near a drafty window.

Check these first

  1. Check if the plant is near a heater or cold window.
  2. Ensure the plant has not been moved to a new room recently.
  3. Verify that the soil is not bone dry or soaking wet.

Likely causes

  1. Temperature fluctuations

    Most likely

    How to tell: The buds fall off shortly after you moved the plant or turned on the heat.

    What to do: Keep your plant in a stable location away from cold drafts, heaters, or air conditioning vents. Consistency is key once the buds start to form.

  2. Light changes

    Possible

    How to tell: The plant was moved to a spot with significantly more or less light.

    What to do: Place the plant in bright indirect light and leave it there. Avoid rotating the pot once the buds appear, as this can confuse the plant.

Questions people ask

Can I move my plant while it is blooming?
It is best to leave it alone. Moving it can cause the buds to drop due to the change in light and temperature.
Does dry soil cause bud drop?
Yes, if the soil gets too dry, the plant may drop buds to conserve energy. Keep the soil lightly moist while it is flowering.
