Yellow Leaves on anthurium
What's Happening
Natural senescence in Anthurium involves nutrient remobilization from older leaves to support emerging new growth. The plant sacrifices the oldest, smallest bottom leaf as a normal physiological process, redirecting nitrogen, chlorophyll, and mobile nutrients to developing inflorescences and new foliage. This occurs every 4-8 weeks in healthy, actively growing specimens and is distinct from stress-induced yellowing.
How to Fix It
- 1
Verify pattern: Single oldest leaf yellowing over 2-4 weeks = natural; multiple leaves or rapid yellowing = problem
- 2
Allow completion: Let leaf fully yellow before removal to maximize nutrient recycling
- 3
Prune properly: Snip at base once yellow/brown, using sterile scissors
- 4
Monitor new growth: Ensure new leaves are healthy and properly sized
- 5
Adjust expectations: Healthy Anthurium naturally sheds 1-2 oldest leaves per year
How to Prevent It
Maintain stable growing conditions (65-80°F, 60-80% humidity, bright indirect light 2000-5000 lux) to minimize unnecessary senescence; provide balanced fertilization (20-20-20 at 1/4 strength monthly) to ensure adequate nutrient availability for both old and new growth.
