Any Houseplant — Brown Leaf Tips/Edges — common problems
Find the symptom you're seeing for the likely cause and fix.
Likely cause: Hot dry air, improper watering, insect feeding, salt buildup, or fluoride/chlorine in tap water.
Fix: Use rainwater or let tap water sit 24 h; periodically leach salts; empty saucers; don't over-fertilize; scrape salt crust and top up soil.
Likely cause: Too little or too much water, root rot, excess fertilizer/salt, or being pot-bound.
Fix: Fix drainage; adjust watering; repot if root-bound; repot in fresh soil to remove mineral buildup.
