temperature for blooming on Anthurium
Quick answer
If your Anthurium has temperature for blooming, the most likely cause is: Anthurium andraeanum inflorescence development requires stable temperatures between 70-85°F (21-29°C) daytime and 60-70°F (15-21°C) nighttime. Temperature fluctuations below 65°F or above 90°F disrupt the SOC1 and AGL6 floral identity gene expression pathways, causing bloom cycle interruption. Cold drafts specifically trigger chilling injury that aborts developing spathes.
Start here:
- 1. Maintain daytime temperature 75-80°F and nighttime 65-70°F for optimal flowering
- 2. Position away from AC vents, drafty windows, and exterior doors
Why Anthurium gets temperature for blooming
Anthurium spp.
Anthurium andraeanum inflorescence development requires stable temperatures between 70-85°F (21-29°C) daytime and 60-70°F (15-21°C) nighttime. Temperature fluctuations below 65°F or above 90°F disrupt the SOC1 and AGL6 floral identity gene expression pathways, causing bloom cycle interruption. Cold drafts specifically trigger chilling injury that aborts developing spathes.
How to reverse temperature for blooming on Anthurium
- 1
Maintain daytime temperature 75-80°F and nighttime 65-70°F for optimal flowering
- 2
Position away from AC vents, drafty windows, and exterior doors
- 3
Use heating mat set to 75°F during winter months to maintain root zone temperature
- 4
Avoid temperature swings greater than 15°F between day and night
- 5
Monitor with digital thermometer at plant level—ambient room temp often differs by 5-10°F
Keep temperature for blooming off this Anthurium
Select stable microclimate location away from HVAC airflow. Use thermostat-controlled heating mat in winter. Maintain consistent year-round temperature to support continuous flowering rather than seasonal bloom cycles.
