Should I cut the brown spots off my peace lily?

Trim for appearance, but do not remove healthy green tissue unnecessarily. For a leaf that is only brown at the tip or edge, snip along the natural leaf shape with clean scissors, leaving a thin margin of brown so you do not cut into living tissue and trigger fresh browning. Remove a whole leaf at the base only when more than about half of it is brown or the leaf has fully yellowed and browned, since a partly green leaf still feeds the plant. Cutting spots off does not fix the cause, so always correct the underlying watering, light, or water-quality problem too.

Can tap water cause brown tips on a peace lily?

Yes. Peace lilies are sensitive to fluoride and chlorine in tap water and to the buildup of salts from softened water, all of which typically show as brown leaf tips and edges rather than round interior spots. If your tap water is fluoridated or heavily chlorinated, switch to filtered water, rainwater, or tap water left to stand uncovered for 24 hours so chlorine dissipates, though standing does not remove fluoride. Never use water from a salt-based water softener on a peace lily, because the added sodium accumulates in the soil and scorches the foliage over time.

Why does my peace lily get brown spots after repotting?

Brown spots after repotting are usually transplant stress or overwatering in fresh mix that holds more moisture than the plant is used to. Disturbed roots take one to three weeks to re-establish and cannot move water efficiently in the meantime, so leaves may spot or brown at the edges. Water lightly, keep the plant out of direct sun, hold off on fertilizer for four to six weeks, and maintain steady humidity. Judge recovery by the newest leaves, which should emerge clean once the roots settle, rather than by the older leaves that were stressed during the move.

Do brown spots on a peace lily spread to other leaves?

It depends on the cause. Brown spots from overwatering, dry air, tap-water minerals, sunburn, or fertilizer salts are physiological and do not spread from leaf to leaf, though new leaves will keep browning until you fix the condition. Dark, spreading spots that look wet or have yellow halos can indicate a fungal or bacterial disease, which does spread, especially in warm, wet, stagnant conditions. If spots keep appearing on new leaves and look water-soaked, isolate the plant, remove the worst leaves, keep the foliage dry, and improve airflow.

My peace lily has brown spots and droops, what is wrong?

Brown spots together with drooping most often point to a watering problem, and the two directions look similar. Overwatering causes soft brown spots, yellowing, and a droop that does not recover after watering, with mushy roots when you check. Underwatering causes crispy brown edges and a droop that perks up within hours of a thorough soak. Feel the soil: soggy points to overwatering and possible root rot, which needs you to stop watering and inspect the roots, while bone dry points to underwatering, which a good watering will fix. Correct the water first, then trim the damaged leaves.

Brown spots on peace lily leaves usually come from one of five causes: overwatering (soft brown spots with yellowing, mushy roots), dry air or underwatering (crispy brown tips and edges), too much direct light (bleached tan patches on sun-facing leaves), fluoride, chlorine, or salts in tap water (brown tips that resist every other fix), and fertilizer salt buildup (scorched edges from overfeeding). The texture and location of the browning tells you which one you have. Read the spots first, then match the fix below — reacting to a soft, overwatered leaf by watering more only accelerates root rot.

Read the spots before you act

Handle the affected leaf and note whether the browning is soft or crispy, where it sits, and whether it is at the edges or in the interior.

What you see	Likely cause	First move
Soft brown spots, yellowing, mushy roots	Overwatering / root rot	Stop watering, check roots, repot if mushy
Crispy brown tips and edges	Dry air, underwatering, or tap water	Raise humidity, review watering and water source
Bleached tan patches on sun-facing leaves	Too much direct light	Move out of direct sun
Brown tips that resist watering fixes	Fluoride, chlorine, or softener salts	Switch to filtered or rainwater
Dark, wet-looking spreading spots with halos	Fungal or bacterial disease	Isolate, remove worst leaves, keep dry

Interior spots that are soft or wet-looking usually mean overwatering or disease; browning confined to tips and edges usually means dry air, water quality, or salts.

Overwatering and root rot

Soft brown spots accompanied by yellowing leaves and a droop that does not recover after watering are the signature of overwatering. Constantly wet soil suffocates the roots, which rot and lose the ability to move water, so the leaves brown even though the mix is wet. Slide the plant out: firm pale roots are healthy, brown mushy roots that smell sour are rot. Trim the rot back to firm tissue with sterile shears, repot into fresh, well-draining mix in a pot with a drainage hole, and water only when the top inch of soil is dry. Peace lilies are dramatic wilters that recover quickly from thirst, so it is safe to let them tell you when they need water rather than watering on a fixed schedule.

Dry air and underwatering — crispy tips

Brown, crispy tips and edges that feel papery point to moisture stress. Peace lilies are tropical understory plants that prefer humidity of 50 percent or higher, and dry indoor air, especially in a heated winter home below 30 percent, browns the tips. Raise humidity with a small humidifier, by grouping plants, or by keeping the plant in a brighter bathroom. At the same time, make sure you are not letting the soil dry out completely between waterings — a peace lily that repeatedly wilts hard before watering will crisp at the edges. Keep the mix lightly, evenly moist.

Too much direct light

Pale tan or bleached brown patches on the leaves facing a window are sunburn. Peace lilies want medium, indirect light and are among the better low-light houseplants; direct sun scorches them. Move the plant back from the window or filter the light with a sheer curtain — an east-facing window or a spot a few feet inside a brighter room is ideal. Scorched patches will not turn green again, but new growth will come in clean once the light is right.

Fluoride, chlorine, and softener salts

If brown tips persist despite correct watering, humidity, and light, suspect your water. Peace lilies are notably sensitive to fluoride and chlorine, and to the sodium in softened water, all of which accumulate in the soil and burn the leaf margins. Switch to filtered water, collected rainwater, or tap water left standing uncovered for 24 hours so chlorine can dissipate — though standing does not remove fluoride, so a filter or rainwater is better if your supply is fluoridated. Never use water from a salt-based softener on a peace lily. Flushing the pot with clean water two or three times a year also helps wash accumulated minerals out of the soil.

Fertilizer salt buildup

Overfeeding leaves a residue of mineral salts in the soil that scorches leaf tips and edges much as hard water does; a white crust on the soil surface or pot rim is the giveaway. Peace lilies are light feeders. Fertilize only during active growth in spring and summer, at half the label strength or less, and flush the soil with plain water occasionally to wash out accumulated salts. If you have been feeding often, leach the pot thoroughly and pause fertilizing until the plant recovers.

Preventing brown spots on a peace lily

Keep the soil evenly, lightly moist — water when the top inch is dry, and never leave it standing in runoff.
Use filtered or rainwater if your tap is fluoridated, chlorinated, or softened.
Give medium, indirect light, away from scorching sun.
Hold humidity at 50 percent or higher, with a humidifier in winter.
Feed lightly and flush the soil to prevent salt buildup.
