fertilizer burn on Philodendron
Quick answer
If your Philodendron has fertilizer burn, the most likely cause is: Over-fertilization causes leaf tip and margin burn as excess salts accumulate in soil, drawing water out of roots through osmosis. This creates drought-like symptoms despite adequate soil moisture. Fertilizer salts also alter soil pH, locking out essential nutrients.
Start here:
- 1. Identify fertilizer burn: brown, crispy tips and margins; yellowing from edges inward
- 2. Stop fertilizing immediately
