Plant Care

If your peace lily's normally glossy, deep-green leaves are showing crispy brown edges or brown-tipped fronds, you're not alone — it's one of the most common complaints from peace lily owners, and the good news is that it's almost always fixable once you know which of six common causes is behind it. Brown tips are rarely fatal on their own; they're your plant's way of signaling a specific care mismatch, and reading the pattern correctly is the fastest way to fix it and keep it from coming back. This guide walks through every cause of peace lily brown tips — from tap water minerals to fertilizer burn to plain old low humidity — with a diagnostic table you can use in under two minutes, plus the exact trimming technique to make damaged leaves look tidy again while your plant recovers. If you're newer to peace lilies, pair this with our full Peace Lily care guide and Peace Lily watering guide for the complete picture. Quick Diagnosis: What Your Brown Tips Are Telling You Before you change anything, look closely at where the brown is and what it looks like. The location and texture of the discoloration narrows down the cause dramatically. What You See Most Likely Cause Fastest Fix Thin, papery brown edges on many leaves, tips curl slightly Low humidity or dry air Raise humidity to 50%+, group plants, use a pebble tray Brown tips with a yellow halo, mostly on older/lower leaves Overwatering / root stress Let soil dry more between waterings, check drainage Sharp, dark brown tips, soil bone-dry between waterings Underwatering Water more consistently, check pot size Brown tips with white or yellow crust visible on soil surface Fertilizer salt buildup or hard tap water minerals Flush soil, switch to filtered/distilled water, cut fertilizer dose Brown patches (not just tips), bleached or scorched-looking Direct sun exposure Move out of direct light Only the very oldest, lowest leaves affected, rest of plant looks great Natural leaf aging Trim the leaf off at the base — this is normal Brown tips plus stunted growth, plant looks "tight" in the pot Root-bound plant Repot into a container 2" larger Cause 1: Low Humidity (the #1 cause) Peace lilies (Spathiphyllum) are tropical understory plants native to Central and South American rainforests, where humidity regularly sits at 60–80%. Most homes run 30–40% humidity, especially with HVAC systems, and that gap is the single most common reason for crispy brown leaf tips. Low humidity causes water to evaporate from the leaf margins faster than the plant's vascular system can resupply it, so the outermost tissue — the leaf tips and edges — dies first. This is especially common in winter (heating dries indoor air dramatically) and in air-conditioned rooms in summer. See our complete guide to humidity for houseplants for room-by-room humidity strategies, but the fast fixes are: Run a small humidifier near the plant (aim for 50%+ relative humidity) Group peace lilies with other moisture-loving plants — they create a shared humidity microclimate Set the pot on a pebble tray with water just below the pot base (never let the pot sit in standing water) Avoid placing peace lilies near heating vents, radiators, or air conditioning units Mist occasionally, though misting alone raises humidity only briefly and isn't a full substitute for ambient humidity Cause 2: Water Quality — Fluoride, Chlorine & Mineral Salts Peace lilies are famously sensitive to fluoride and chlorine, both common in municipal tap water. Fluoride accumulates in leaf tissue over time and causes a very specific symptom: tan-to-brown necrotic tips, often with a slightly yellow border, that progress from the leaf margin inward. This is different from humidity-related browning, which tends to be thinner and more uniform along the edge. Hard tap water also deposits calcium and magnesium salts in the soil over repeated waterings, which can burn root tips and cause the same above-ground symptom. If you see a white or yellowish crust on the soil surface or pot rim, mineral buildup is very likely a contributing factor. Water Type Peace Lily Safety Notes Tap water (fluoridated) Risky for sensitive plants Let sit uncovered 24 hours to offgas some chlorine; doesn't remove fluoride Filtered (carbon/Brita-style) Better Removes chlorine and some minerals, not fluoride Distilled or reverse osmosis Safest Removes fluoride, chlorine, and mineral salts entirely Rainwater Excellent Naturally soft and mineral-free where safe to collect If fluoride/mineral buildup is the suspected cause, flush the pot thoroughly by running plain distilled water through the soil until it drains freely from the bottom (roughly 3x the pot volume), then switch your regular watering source going forward. Cause 3: Overwatering and Root Stress Counterintuitively, overwatering is one of the most common causes of brown tips — not just yellowing. When roots sit in soggy soil, they lose their ability to take up water and nutrients efficiently (and in advanced cases, begin to rot), so the plant shows drought-like symptoms even though the soil is wet. This is why "just water it more" often makes brown tips worse, not better. Signs pointing to overwatering rather than underwatering: brown tips paired with yellowing on lower/older leaves, a sour or musty soil smell, soil that stays wet for more than 5–7 days, or visible mushy/dark roots when you check the root ball. Our Overwatered vs. Underwatered guide has a full side-by-side comparison, and if roots are already affected, see our Root Rot Treatment guide. Peace lilies want soil that's evenly moist but never waterlogged — let the top 1–2 inches dry out before watering again, and always use a pot with drainage holes. Cause 4: Underwatering and Drought Stress Peace lilies are famous for dramatically drooping when thirsty — but if they go too long between waterings repeatedly, leaf tips will brown and crisp up from drought stress before the whole leaf collapses. This tends to produce sharper, darker brown tips than humidity-related browning, and the surrounding leaf tissue often looks slightly dull or matte rather than glossy. Check soil moisture with a finger 2 inches deep — if it's bone dry and the plant has drooped more than once in recent weeks, build a more consistent watering schedule. See our full Watering Indoor Plants guide for a seasonal watering framework that applies well to peace lilies. Cause 5: Fertilizer Burn Peace lilies are light feeders. Over-fertilizing — or fertilizing a plant that's stressed, dormant, or recently repotted — causes a buildup of mineral salts in the soil that literally burns root tips, which shows up above ground as brown, crispy leaf margins. This is one of the most common mistakes with well-meaning owners who fertilize on a strict monthly schedule regardless of season or plant condition. Fertilize no more than once a month during spring/summer active growth, and skip it entirely in fall/winter Always dilute liquid fertilizer to half the label-recommended strength for peace lilies Never fertilize a plant with dry soil — apply only after regular watering If you suspect burn, flush the pot with plain water to leach out excess salts See our Indoor Plant Fertilizer Guide for dosing and timing specifics. Cause 6: Direct Sunlight and Scorch Peace lilies are understory plants adapted to filtered, indirect light. Direct afternoon sun — especially through south- or west-facing windows in summer — can scorch leaf tissue, which shows up as bleached, papery brown patches (often larger than just the tip) or a general washed-out look to the whole leaf. This is different from the other causes because it tends to affect only the sun-facing side of the plant. Move the plant a few feet back from direct light, add a sheer curtain, or relocate to an east-facing window where morning light is gentler. Cause 7: Natural Aging (Not a Problem) If only the very oldest, lowest leaves on an otherwise healthy plant are browning, this is simply normal leaf senescence — plants continuously shed old leaves as they grow new ones. Trim the affected leaf off at its base near the soil line and don't worry about it further, as long as new growth continues to look healthy. Cause 8: Root-Bound Plants A peace lily that's been in the same pot for 2+ years may become root-bound, where roots circle the pot and can no longer efficiently absorb water and nutrients — leading to brown tips alongside stalled growth and roots visible at drainage holes or pushing up through the soil surface. If you see these signs, it's time to repot into a container about 2 inches larger in diameter. See our step-by-step repotting guide and our best soil mixes guide for a peace-lily-friendly, well-draining mix. Special Case: Brown Tips on a Newly Shipped Peace Lily If your peace lily arrived with a few brown tips already present, don't panic — this is common with live plant shipping and usually isn't a sign of a sick plant. A few things happen in transit that can cause temporary tip browning: Humidity shock — the plant goes from a greenhouse at 70%+ humidity to a cardboard box, then to your home's (likely much drier) air, all within days Temperature swings — shipping trucks and porches can expose plants to brief cold or heat stress, especially in extreme weather Light change — a plant grown under greenhouse lighting adjusts over 1–2 weeks to your home's natural light Root disturbance — minor root stress from the pot shifting in transit can show up as minor tip browning within the first week The fix is simple: don't repot or fertilize immediately. Give the plant 2–3 weeks to acclimate in a stable spot with indirect light and consistent watering, trim any tips that were already brown on arrival for appearance, and watch for new growth — vigorous new leaves are the best sign the plant has settled in well. If new leaves also start showing brown tips after the acclimation window, work through the causes above starting with humidity and water quality. Seasonal Troubleshooting Guide Season Common Cause What to Adjust Winter Heating-dried air, cold drafts near windows/doors Run a humidifier, move plant away from vents and drafty windows, reduce watering slightly as growth slows Spring Resuming fertilizer too aggressively after winter dormancy Reintroduce fertilizer at half-strength, watch for salt buildup Summer Direct sun through summer-angle windows, AC drying the air Filter or move away from intense afternoon light, add humidity support Fall Watering habits not adjusted as growth slows with shorter days Let soil dry a bit more between waterings to avoid root stress How to Trim Brown Tips (Without Making It Worse) Trimming won't stop the underlying cause, but it does prevent the plant from wasting energy on damaged tissue and keeps it looking tidy while you fix the real problem. Use clean, sharp scissors and follow the natural leaf shape: Sterilize scissors or micro-snips with rubbing alcohol before and after use Cut along the natural angle of the leaf tip, following its point rather than cutting straight across — this looks far more natural than a blunt cut Cut just inside the brown tissue, leaving a very thin margin of brown rather than cutting deep into healthy green tissue If more than 50% of a leaf is affected, remove the entire leaf at its base instead of trimming Never trim more than a few leaves in one sitting — spread it out to avoid additional stress Prevention Checklist Factor Target for Peace Lily Humidity 50%+ relative humidity Water source Filtered, distilled, or rested tap water Watering schedule Water when top 1–2" of soil is dry; never let it sit soggy Light Bright, indirect light — no direct afternoon sun Fertilizer Half-strength, monthly, spring/summer only Pot size Repot every 1–2 years as roots fill the container Frequently Asked Questions Will brown tips turn green again? No — damaged leaf tissue does not heal or turn back green. Fix the underlying cause to stop new damage, then trim the existing brown tips for appearance. New growth should come in healthy if the cause is corrected. Is it normal for peace lilies to get some brown tips occasionally? A few brown tips here and there, especially on older leaves, is common and not a sign of a serious problem. Widespread browning across many leaves — especially new growth — signals a care issue that needs addressing. Should I remove the whole leaf or just the brown tip? If less than half the leaf is affected, trim just the brown portion following the leaf's natural shape. If more than half is brown or the leaf looks otherwise unhealthy, remove the entire leaf at the base. Can tap water really cause brown tips? Yes — peace lilies are among the more sensitive common houseplants to fluoride, chlorine, and mineral salts in tap water. Switching to filtered or distilled water is one of the highest-impact changes you can make if you've ruled out humidity and watering issues. My peace lily's leaves are turning yellow, not brown — is that the same issue? Not necessarily. Yellowing usually points to overwatering, nutrient deficiency, or natural aging rather than the humidity/mineral causes behind brown tips. See our guide to yellowing houseplant leaves for a full breakdown. Does trimming brown tips encourage new growth? Trimming doesn't directly stimulate growth, but it stops the plant from putting any further energy toward already-dead tissue and keeps the plant looking its best. New growth comes from correcting the underlying cause — proper humidity, water quality, and a consistent watering rhythm — not from pruning alone. How long does it take to see improvement after fixing the cause? Existing brown tips will never green back up, but you should see new leaves emerging healthy within 3–6 weeks once the underlying issue (humidity, water quality, watering schedule, or light) is corrected. Peace lilies are fairly fast growers under good conditions, so patience combined with consistency pays off quickly. Can I use ice cubes to water my peace lily and avoid brown tips? We don't recommend the ice cube method for peace lilies. Cold water and cold root contact can stress tropical plants like peace lilies, potentially contributing to the very leaf damage you're trying to avoid. Stick with room-temperature filtered or distilled water instead.

How to Care for Peace Lily: The Complete Guide Few houseplants combine elegance, simplicity, and resilience quite like the Peace Lily (Spathiphyllum). With its glossy dark green foliage and graceful white blooms, the Peace Lily brings a sense of calm to any room — and it thrives in conditions that would challenge most flowering plants. Here's how to give your Peace Lily the care it deserves. Peace Lily at a Glance Botanical Name Spathiphyllum spp. Common Names Peace Lily, Spath, White Sails Plant Type Evergreen tropical perennial Mature Size 1–4 ft. tall depending on variety Light Low to medium indirect Water When top inch of soil is dry (or when leaves begin to droop) Humidity 50–70% (tolerates 40%) Temperature 65–80°F (18–27°C) Soil Rich, well-draining potting mix Toxicity Mildly toxic to pets and children Difficulty Beginner-friendly Light Requirements Peace Lilies are among the best low-light indoor plants available. In their native tropical habitats, they grow on the forest floor under dense canopy shade — so they're naturally equipped for dim indoor conditions. Low to medium indirect light — The ideal range. Peace Lilies actually prefer less light than most houseplants. This makes them perfect for north-facing rooms, bathrooms with small windows, and interior offices. Bright indirect light — Produces more flowers but can cause leaves to yellow if too intense. Keep away from direct window light. Direct sunlight — Avoid entirely. Direct sun scorches the delicate leaves, causing permanent brown spots and bleached patches. Flowering tip: If your Peace Lily is healthy but not blooming, try giving it slightly more light. A spot with consistent, gentle indirect light often triggers flower production. Peace Lilies that don't bloom are usually in conditions that are too dark — they'll survive but won't flower. Watering The Peace Lily is the ultimate "communication plant." When it's thirsty, it tells you — dramatically. The entire plant droops, leaves wilting downward like a fainting Victorian. Water it, and within hours it perks right back up as if nothing happened. This built-in feedback system makes it one of the best plants for learning to read your plants' needs. How to water: Water when the top inch of soil feels dry, or when you notice the very earliest signs of drooping. Water thoroughly until it flows from the drainage holes, then let the pot drain completely. Spring/Summer: Water roughly every 5–7 days Fall/Winter: Every 7–10 days Underwatered: Dramatic wilting (recovers quickly after watering) Overwatered: Yellow leaves, black mushy roots, soil that stays wet for days Important: While Peace Lilies forgive the occasional drooping episode, don't make a habit of letting them fully wilt before watering. Repeated severe drooping stresses the plant and can eventually cause leaf tip browning and reduced flowering. Humidity Peace Lilies are tropical plants that naturally thrive in humid environments. While they tolerate average household humidity (40–50%), they'll look their absolute best at 50–70% humidity. Signs your Peace Lily wants more humidity: Brown, crispy leaf tips and edges Leaves that look dull rather than glossy Boost humidity by: Running a humidifier nearby Placing on a pebble tray with water Grouping with other plants Keeping in a bathroom with natural light Peace Lilies are one of the best plants for bedrooms and bathrooms — they thrive in the naturally higher humidity these rooms provide. Temperature Keep your Peace Lily in 65–80°F (18–27°C). These tropical plants have zero tolerance for cold. Temperatures below 55°F (13°C) can cause cold damage, and they should never be exposed to frost. Avoid placing Peace Lilies near: Exterior doors that let in cold drafts Air conditioning vents (cold air dries out foliage) Uninsulated windows during winter Soil Peace Lilies prefer a rich, moisture-retentive but well-draining potting mix. They like soil that stays lightly moist (not wet). A good mix: 2 parts peat moss or coco coir 1 part perlite 1 part compost or worm castings Peace Lilies don't need frequent repotting — every 2–3 years is sufficient. They actually bloom better when slightly root-bound. When you do repot, go up only one pot size. Our repotting guide walks you through the process step by step. Fertilizing Growing season (spring–summer): Feed every 6–8 weeks with a balanced liquid fertilizer at half strength. Peace Lilies are light feeders — over-fertilizing causes more problems than under-fertilizing Fall/Winter: Skip fertilizing entirely Bloom-boosting tip: Use a fertilizer slightly higher in phosphorus (the middle number, e.g., 10-30-20) during spring to encourage flowering Propagation Unlike vining plants that propagate from stem cuttings, Peace Lilies are propagated by division — separating the root system into multiple plants during repotting. How to Divide a Peace Lily Remove the Peace Lily from its pot Gently shake or rinse away soil from the roots Look for natural divisions — separate clusters of leaves with their own root systems Gently pull or cut the root mass apart, ensuring each division has at least 2–3 leaves and a healthy root cluster Plant each division in its own pot with fresh, moist potting mix Water lightly and keep in a warm, humid spot with indirect light Avoid fertilizing for 4–6 weeks while the new plants establish The best time to divide is during spring repotting when the plant is entering its active growth phase. Common Problems Brown Leaf Tips The most common Peace Lily complaint. Causes include low humidity, inconsistent watering, fluoride in tap water, or over-fertilizing. Trim brown tips with clean scissors (cut at an angle for a natural look), then address the underlying cause. Switching to filtered water often solves persistent browning. Yellow Leaves Overwatering is the usual culprit. Check that your pot has drainage holes and that you're allowing the top inch of soil to dry between waterings. Old leaves occasionally yellow naturally — this is normal. No Flowers Peace Lilies need sufficient light, maturity, and a slight pot-bound condition to bloom. Move to a brighter location (still indirect), ensure the plant is established (at least 1 year in its pot), and try a phosphorus-boosted fertilizer in spring. Green Flowers Peace Lily spathes (the white "flowers") naturally turn green as they age. This is normal. Cut spent spathes at the base of their stem to redirect the plant's energy into producing new blooms. Drooping If your Peace Lily is drooping, check the soil. If it's dry, water immediately — the plant will recover within hours. If the soil is wet and the plant is still drooping, you may have root rot. Unpot, inspect roots, trim away any black or mushy roots, and repot in fresh soil. Peace Lily & Air Purification Peace Lilies are among the top performers in NASA's landmark Clean Air Study, effectively removing benzene, formaldehyde, trichloroethylene, ammonia, and xylene from indoor air. They're one of the most effective air-purifying houseplants available — and unlike most air-purifying plants, they do this in low light conditions where other plants can't function. 👉 Shop Peace Lily · Shop Peace Lily Starter Plant Frequently Asked Questions How often should I water a Peace Lily? Water when the top inch of soil feels dry — roughly every 5–7 days in warm months and every 7–10 days in winter. Peace Lilies communicate clearly: they droop dramatically when thirsty and perk back up within hours of watering. The best approach is to learn your plant's visual cues rather than following a rigid schedule. Why is my Peace Lily not flowering? The three most common reasons: not enough light (move to a brighter indirect spot), the plant is too young (Peace Lilies need to be mature, usually 1+ years), or the pot is too large (they bloom better when slightly root-bound). A phosphorus-rich fertilizer in spring can also encourage blooming. Are Peace Lilies toxic to pets? Peace Lilies contain calcium oxalate crystals and are mildly toxic to cats and dogs. Ingestion causes oral irritation, drooling, and difficulty swallowing. Keep Peace Lilies out of reach of pets, or opt for pet-safe houseplants like Spider Plants or Calathea. Can Peace Lilies grow in just water? Yes, Peace Lilies can grow hydroponically. Place the plant in a glass container with the roots submerged in water. Use a support (like glass beads or stones) to hold the plant upright. Change the water every 1–2 weeks and add a small amount of liquid fertilizer monthly. How long do Peace Lily flowers last? Individual Peace Lily blooms (spathes) last about 4–6 weeks before gradually turning green and fading. A healthy, well-lit Peace Lily can produce blooms throughout spring and summer, and occasionally in fall. Cut spent flowers at the base of the stem to encourage new blooms.
