Yellow Leaves on bird of paradise
What's Happening
Nutrient deficiency (nitrogen or magnesium) causes sudden yellowing of newer leaves on Bird of Paradise. The plant's slow growth rate (2-3 leaves annually) leads to nutrient prioritization toward mature foliage; emerging growth suffers when mobile nutrients are remobilized from newer to older leaves during deficiency stress.
How to Fix It
- 1
1. Apply balanced all-purpose fertilizer (10-10-10 NPK) at half strength
- 2
2. Fertilize once every 4 weeks during active growth period
- 3
3. Inspect undersides of leaves and soil for pests using magnifying glass
- 4
4. Ensure bright indirect light (2000-5000 lux) and humidity above 50%
- 5
5. Prune yellow leaf at base to redirect energy; avoid removing more than 20% foliage
How to Prevent It
Implement monthly fertilization with balanced NPK during active growth (spring-fall); maintain 60-70% humidity and consistent bright indirect light to support nutrient uptake.
