fertilizer burn on Pothos
Quick answer
If your Pothos has fertilizer burn, the most likely cause is: Pothos (Epipremnum aureum) exhibits high tolerance to under-fertilization but rapid salt sensitivity due to aroid physiology. Fertilizer burn manifests as marginal necrosis from osmotic stress rather than root rot, occurring when electrical conductivity (EC) exceeds 1.0-1.5 mS/cm in the root zone.
Start here:
- 1. Use balanced 10-10-10 or 20-20-20 formulations diluted to 1/4 label strength
- 2. Apply every 4-6 weeks during spring-summer active growth only
Why Pothos gets fertilizer burn
Epipremnum aureum
Pothos (Epipremnum aureum) exhibits high tolerance to under-fertilization but rapid salt sensitivity due to aroid physiology. Fertilizer burn manifests as marginal necrosis from osmotic stress rather than root rot, occurring when electrical conductivity (EC) exceeds 1.0-1.5 mS/cm in the root zone.
How to reverse fertilizer burn on Pothos
- 1
Use balanced 10-10-10 or 20-20-20 formulations diluted to 1/4 label strength
- 2
Apply every 4-6 weeks during spring-summer active growth only
- 3
Water with plain water between feedings to flush excess salts
- 4
Target EC below 1.0 mS/cm for optimal root health
- 5
Use organic alternatives like worm castings tea (1 cup castings steeped in 1 gallon water for 24-48 hours, diluted 1:1) or fish emulsion at 1/4 strength
Keep fertilizer burn off this Pothos
Never apply fertilizer to dry soil. Water thoroughly 24 hours before feeding. Flush soil monthly with 3x pot volume of plain water to prevent salt accumulation.
