Why Are My Plant's Leaf Tips Turning Brown?

Brown leaf tips mean the very ends of the leaves are drying out because water isn't reaching them fast enough, or because salts are building up there. The most common causes are uneven watering, low humidity, a buildup of minerals or fertilizer in the soil, and damaged roots. The brown parts won't turn green again, but once you fix the cause, new leaves should come in clean.

Why the tips go first

Leaf tips and edges are the farthest point from the roots. Water travels up through the plant and evaporates from the leaves, carrying dissolved minerals with it. When the supply is interrupted, or when evaporation outpaces it, the tips are the first tissue to run short and die. Salts carried in that water also tend to concentrate at the tips and margins as the water evaporates, which is why mineral and fertilizer problems show up there too.

That shared mechanism is why so many different problems produce the same symptom. The trick is reading the details.

The main causes, and how to tell them apart

Inconsistent watering

This is the most frequent cause. A plant that swings between bone-dry and soaked has roots that can't keep a steady supply going. Letting a plant dry out completely, then flooding it, damages the fine root hairs, and the tips pay the price.

What it looks like: crisp, dry brown tips, sometimes with a yellow band between the brown and the green. Often appears on several leaves at once after a missed watering or a vacation.

Low humidity

Indoor air gets dry, especially in winter when the heat is on. Tropical plants with thin leaves, like calatheas, prayer plants, ferns, spider plants and some palms, lose moisture through their leaves faster than their roots can replace it.

What it looks like: thin, papery brown tips across many leaves, worse on plants near heating vents, radiators or drafty windows. Thick-leaved plants like snake plants and ZZ plants are rarely affected by humidity alone.

Salt, mineral and fluoride buildup

Tap water carries dissolved minerals, and fertilizer adds more salts. Over time these accumulate in the potting mix, especially if you water in small sips that never drain through the bottom of the pot. Some plants, including dracaenas, spider plants and some prayer plants, are known to be sensitive to fluoride in tap water.

What it looks like: brown tips, sometimes with a darker line between brown and green, plus a white or crusty residue on the soil surface or the rim of the pot. Older leaves usually show it more than new ones.

Fertilizer burn

Feeding too often, using too strong a mix, or fertilizing a dry plant can scorch the roots, which then can't take up water properly.

What it looks like: browning that appears shortly after feeding, often on the tips and edges of many leaves at once. You may see crust on the soil as well.

Root problems

If the roots are rotting from overwatering or are tightly packed in a pot they've outgrown, they can't deliver enough water no matter how much you give. Our guide to overwatering vs underwatering covers how to tell those two apart.

What it looks like: brown tips together with yellowing, drooping or soft stems, soil that stays wet for days, or a sour smell. In a root-bound plant, roots will be circling the pot or poking out of the drainage holes, and water runs straight through.

A quick way to narrow it down

Start with the soil. Push a finger an inch or two in.

• Very dry, and the plant has been drying out hard between waterings: inconsistent watering is the likely cause.
• Wet, and it's been days since you watered: suspect overwatering and check the roots.
• White crust on top or on the pot: salt or fertilizer buildup.
• Soil seems fine, plant sits near a heater or in a dry room, and it's a thin-leaved tropical: humidity.

Then think about timing. Browning that appeared after a fertilizer feed, a repot, a move or a vacation is usually tied to that event.

How to fix it

Even out your watering. Water thoroughly until it drains from the bottom, then wait until the right amount of soil has dried before watering again. That amount varies by plant: most tropicals like the top inch or two to dry, while succulents and snake plants want to dry most of the way through. Checking the soil beats a fixed schedule.

Raise humidity for the plants that need it. Group humidity-loving plants together, move them away from heat sources and drafts, or run a humidifier nearby. Pebble trays and misting give only a small, short-lived bump, so a humidifier is the more reliable option for fussy plants like calatheas.

Flush the soil. Every couple of months, take the plant to a sink or tub and run plenty of water slowly through the pot, several times the volume of the pot, to wash out accumulated salts. Let it drain completely.

Switch water for sensitive plants. If you suspect fluoride, try distilled water or rainwater for plants like dracaenas and spider plants. Letting tap water sit out overnight can help with chlorine, but it won't remove fluoride.

Ease up on fertilizer. Feed only during active growth in spring and summer, dilute to half the label strength, and never fertilize a bone-dry plant. If you've overdone it, flush the soil and skip feeding for a couple of months.

Check and fix the roots. If the soil stays wet and the plant is declining, slide it out of the pot. Healthy roots are firm and pale; rotten ones are brown, mushy and smelly. Trim the rot and repot into fresh, well-draining mix. If the plant is badly root-bound, move it up one pot size.

Should you trim brown leaf tips?

Yes, if they bother you. The brown tissue is dead and won't recover, and trimming it is purely cosmetic. It won't hurt the plant if you do it carefully.

Use clean, sharp scissors and follow the natural shape of the leaf, cutting at an angle so the tip still looks pointed. Leave a very thin sliver of brown rather than cutting into the green; cutting into healthy tissue opens a fresh wound that can brown again. If most of a leaf is brown, remove the whole leaf at the base instead.

Trimming hides the symptom, so pair it with fixing the cause. Otherwise the new tips will brown too.

Plant-specific patterns

Some plants are famous for brown tips. Spider plants and dracaenas react to fluoride and salts. Calatheas, prayer plants and ferns brown in dry air. Peace lilies brown at the tips when watering is uneven, since they swing from thirsty to soggy quickly. Snake plants rarely brown at the tips unless overwatered or left dry for a very long time. If your plant has brown spots in the middle of the leaf rather than at the tips, that's a different problem, often covered in our fiddle leaf fig brown spots guide.

Common questions

Will brown leaf tips turn green again?

No. Once the tissue has died and turned brown, it can't recover. What you can control is new growth: once the cause is fixed, new leaves should come in without brown tips, and you can trim the old tips for appearance.

Does misting help with brown tips?

Only a little. Misting raises humidity around the leaves for a short time, then it evaporates. If low humidity is the cause, grouping plants together and running a humidifier makes a much bigger difference.

Can tap water cause brown tips?

It can, especially on plants sensitive to fluoride and dissolved salts, such as spider plants and dracaenas. Flushing the soil regularly helps, and switching to distilled water or rainwater for those plants usually reduces the browning on new leaves.

Is it normal for old leaves to get brown tips?

A few brown tips on the oldest leaves of a plant that's otherwise growing well is common and not a cause for worry. If browning is spreading to many leaves, appearing on new growth, or coming with yellowing or drooping, look for one of the causes above.
