Likely causes
Lack of temperature drop
Most likelyHow to tell: The plant looks healthy and grows leaves but never produces a flower spike. This happens when indoor temperatures stay constant all year.
What to do: Move your orchid to a spot where the temperature drops by 10 to 15 degrees at night for 2 to 4 weeks. Keep it in this cooler location during the fall to signal that it is time to bloom.
Insufficient light
Most likelyHow to tell: The leaves are dark green instead of a bright, grassy green. Without enough light, the plant lacks the energy to produce flowers.
What to do: Move the orchid to a brighter location with filtered, indirect light. Avoid direct sun, which can burn the leaves.

Stopping it coming back

Questions people ask
- Should I cut the flower spike after it blooms?
- You can cut the spike down to the base once it turns brown. If it stays green, you can trim it just above a node to see if it produces a secondary bloom.
- Does fertilizer help with blooming?
- Yes, using a balanced orchid fertilizer every 2 to 4 weeks during the growing season supports flower production. Do not fertilize while the plant is resting.
