Fertilizer Burn on fiddle leaf fig
What's Happening
Using high-salt or incorrect NPK ratios (like high phosphorus) can lead to mineral buildup and 'burnt' leaf tips. Ficus lyrata thrives on a nitrogen-heavy 3-1-2 ratio.
How to Fix It
- 1
Switch to a liquid 3-1-2 fertilizer (e.g., Dyna-Gro Foliage-Pro) at half strength.
- 2
Flush the soil with plain water every 3 months to leach out accumulated salts.
- 3
Only fertilize during active growth (Spring/Summer).
How to Prevent It
Avoid slow-release pellets if you prefer precise control. Never fertilize dry soil; water first to protect sensitive root hairs.
