Fertilizer Burn on Houseplants: Symptoms & Fix Guide
Fertilizer burn is one of the most misdiagnosed houseplant problems because its symptoms — brown tips, wilting, yellowing leaves — are nearly identical to overwatering, underwatering, and root rot. The treatment for root rot is opposite to the treatment for fertilizer burn, which means getting the diagnosis wrong makes the plant worse. This guide is built around that diagnostic problem first.

Troubleshooting Guide
1 Why are my Venus Flytrap traps turning black?
Diagnosis: Normal die-off after feeding or stress (tap water, low light)
Treatment: If old traps, trim; if all, use distilled water and give full sun.
Prevention: Use distilled water; provide full sun.
2 Why isn't my Venus Flytrap closing on insects?
Diagnosis: Lack of stimulation (dead prey) or plant is dormant
Treatment: Gently tickle trigger hairs to test; if no response, it may be dormant.
Prevention: Know its dormancy cycle.
3 Why is my Venus Flytrap turning brown in winter?
Diagnosis: Natural winter dormancy
Treatment: Reduce water and keep in a cool (but not freezing) place; it will return in spring.
Prevention: Allow dormancy.
