What causes fertilizer burn on houseplants?
It depends on the plant and how it is kept, so check the plant pages below. For Boston Fern, the records explain it like this: Boston ferns are light feeders sensitive to excess nitrogen and fertilizer salts. Strong synthetic fertilizers cause leaf burn, pale or yellowing fronds, and root damage. The symptoms often appear as browning leaf margins, stunted growth, and overall decline. Ferns evolved in nutrient-poor forest understories and require only minimal feeding.
Common first steps
- Stop all fertilization immediately
- Flush soil thoroughly with distilled water to leach excess salts (3x pot volume)
- Switch to a mild, balanced organic fertilizer like 2-2-2 at half-strength
