Why Coffea arabica has brown tips

Brown tips on Coffea arabica are a pattern to inspect, not a single answer. Dry margins differ from spots, scorched patches or leaves that are also dropping.

Check the leaves, stems and pot

What kind of brown mark is it?

Separate dry brown tips or margins from discrete brown spots, broad scorched patches and leaves that are also dropping. The visible categories guide observation only. They do not identify one cause or prove a coffee-specific disease.

Check whether the mix is consistently damp or staying wet, whether roots and drainage look sound, and whether the plant is near dry air, a radiator, a cold draft, strong sun or a window. Also review water quality, fertilizer or salt buildup, humidity, temperature and pests or spreading spots.

Possible causes and next checks

What could cause it

Brown tips can follow low humidity or dry air, inconsistent watering, soil that remains too wet, fertilizer or soluble-salt buildup, unsuitable water quality or high pH, direct heat or sun, drafts and cold stress, and pests or leaf spots when the pattern is spreading.

What to do next

First compare moisture and drainage with the exact plant’s preference for consistently damp but not soggy mix. Then stabilize humidity and temperature, move the pot away from harsh sun or drafts, review water and fertilizer history and trim only dead brown tissue for appearance while the pattern is watched.

Watch for new damage or recovery

What to watch on new leaves

After one environmental change, watch the newest leaves, whether new tips brown, whether spots spread and whether leaf drop continues. Old dead tissue will not return to green, and no reliable day-based recovery interval is established.

Do not diagnose from one sign alone
