Brown tips on leaves

Brown, crispy tips usually come from one of three things: soil that dried out too much, very dry air, or salts and fluoride building up from tap water and fertilizer. Look at the pattern and at which plant it is — that tells you which.

Brown tips don’t turn green again. The goal is clean new leaves.

Read the pattern

What you see	Most likely cause
Crispy tips on many leaves + soil pulling away from the pot	Underwatering / soil drying out completely
Crispy tips and edges, worst in winter, on ferns or calatheas	Dry air from heating
Tips brown on spider plants, dracaenas or calatheas even with good watering	Fluoride or salts in tap water
White crust on soil or pot rim + brown tips	Fertilizer salt buildup
Brown tips with yellow bands and soft lower leaves	Overwatering / root damage
Brown, scorched patches on the side facing the window	Sunburn

1. Soil drying out completely

The tip is the farthest point from the roots, so it’s the first part to suffer when water runs short. Fix: water thoroughly when the top 1–2 inches are dry, and don’t let moisture-lovers go bone dry. Watering chart for 24 plants →

2. Dry air

Heated US homes in winter can be very dry. Thin-leaved tropicals show it first. Fix: group plants, use a room humidifier, or move sensitive plants to a bright bathroom. Misting won’t do much — here’s why.

3. Fluoride and chlorine compounds in tap water

Some plants are known for reacting to fluoride in tap water:

Sensitive	Usually not bothered
Spider plant, dracaena, calathea, parlor palm, peace lily	Pothos, snake plant, ZZ plant, monstera, succulents

Fix: use filtered, distilled or rain water for the sensitive ones. Letting tap water sit out overnight doesn’t remove fluoride.

4. Fertilizer salts

Too much fertilizer, or fertilizing a dry plant, leaves salts that burn root tips — and leaf tips follow. Fix: flush the pot by running water through it for a couple of minutes, then feed less often and at half strength. Fertilizer dilution chart →

5. Overwatering

It sounds backwards, but rotting roots can’t deliver water either, so tips brown while the soil is wet. If the soil is soggy and lower leaves are yellow and soft, read overwatered vs. underwatered.

6. Sunburn

Dry, pale-brown patches on the leaves facing the glass, especially after moving a plant into a sunnier spot. Move it a few feet back or behind a sheer curtain.

Trimming brown tips neatly

1. Use clean, sharp scissors.
2. Cut following the leaf’s natural shape — a pointed tip for pointed leaves, a rounded one for rounded leaves.
3. Leave a hair-thin line of brown so you don’t open fresh wounds in healthy tissue.
4. Remove leaves that are more than half brown at the base instead.
