Anthurium and Seasonal Change
Share
🌡️ Temperature & Light
1. Anthuriums thrive in stable warmth — they prefer temps between 65–80°F (18–27°C).
→ Sudden drops below 60°F can slow growth or trigger leaf yellowing.
2. Seasonal light shifts matter!
Fall/Winter: Shorter days can lead to slower metabolism, smaller leaves, and fewer blooms.
Spring/Summer: Longer days encourage faster leaf and root development.
3. Adjust lighting during fall/winter by moving plants closer to bright east or south-facing windows (or using grow lights) to maintain consistent growth.

💧 Water & Humidity
4. Less water is needed in cooler months since growth slows and evaporation decreases — overwatering in winter can easily lead to root rot.
5. Humidity often drops indoors when heating starts. Anthuriums love 60–80% humidity, so a humidifier or pebble tray helps prevent crisping edges.

🌱 Growth & Dormancy
6. Anthuriums don’t fully go dormant, but they enter a semi-rest period during cooler months, focusing more on root and energy storage than leaf or bloom production.
7. You may see new leaves unfurl slower or not at all in late fall/winter — totally normal!

🌸 Blooming Cycles
8. Some species naturally reduce blooming in winter, then pick up again with longer daylight in spring.
→ Consistent warmth and light can sometimes “trick” them into blooming year-round indoors.
9. Fertilize less in fall/winter (once a month or less) and resume regular feeding in spring to align with their natural rhythm.

🐛 Pest & Disease Tips
10. Seasonal transitions (especially into fall) can bring pest spikes — thrips, mites, and fungus gnats love warm, humid environments.
→ Wipe leaves, refresh soil top layer, and increase air circulation as preventive care.
