Common Reasons Why Peace Lily Leaves Turn Brown

4 Min Read

Peace lilies are beloved by many for their exquisite white blooms, but these houseplants are exceptionally lovely even out of bloom. Even without blooms, I would still grow peace lilies because of their gorgeous, glossy green leaves.

That is unless the leaves seem less than ideal, which can happen when they frequently turn brown at the tips. In this Article, We include Common Reasons Why Peace Lily Leaves Turn Brown.

Reason of Brown Leaf Tips on Peace Lilies


The first thing to do when the leaves on your peace lily begin to turn brown is to review the watering schedule. Watering can is difficult at first until you figure out a schedule to keep your plant as healthy as possible.

Overwatering is the most common cause of brown foliage. The soil around your peace lily has to remain mostly moist, but too much moisture could lead to root rot, which speeds up the degeneration of the plant’s foliage.

Before the leaves start to wither, give your peace lily some water. It could take some trial and error, so look into any drooping leaves as soon as you see them. Examine the top inch of soil for moisture after it has dried.

Inadequate Drainage

Put your peace lily in a container with lots of drainage holes. Soggy soil can result in faded or absent blooms, brown foliage, and root rot. They can withstand being somewhat root-bound, but they cannot absorb enough moisture if roots begin to round the container or protrude through drainage holes.

Never leave the pot in standing water or water just until the top inch of soil is dry. Let excess water drain away. If the plant becomes too root-bound, repot it into a container that is one to two inches larger. Just before repotting, untangle the roots.

Temperature Extremes

Peace lilies may become stressed by extreme temperature changes, which can cause the leaves to turn brown. Their optimal temperature range is between 65 and 75 degrees Fahrenheit. Keep the cool air currents away from your plant.

It is advised to locate them away from doorways and heating and air conditioning vents. Stop leaves from dropping onto cold surfaces, such as window glass. When the daytime high falls below sixty degrees Fahrenheit, peace lilies become damaged.

Under watering

Your peace lily might be underwater, and the first indication is yellowing foliage. The foliage will gradually go brown and become yellow before dying back. Determining whether there is too much or not enough watering is crucial because dryness can also lead to wilting in plants.

An irrigation schedule needs to be established. Whether a plant is root-bound, how much light it receives, and the humidity level affect how frequently it has to be watered. During the spring and summer growing seasons, watering once a week is a smart place to start.

Sprit zing or spraying foliage is beneficial as well. A reduction in irrigation to once every two weeks is possible throughout the winter.

Chemically-Treated Water

The leaf tips and edges of peace lilies can become brittle and brown when exposed to chemically treated tap water. To let chemicals evaporate, leave tap water on a counter for one or two days before using it. Recycled water from an air conditioner humidifier, or distilled water, can also be used.

Lack of Humidity

Naturally occurring in rainforests with continuously moist air are peace lilies. The humidity levels in typical homes are frequently too low to maintain healthy, green foliage. The plant requires more humidity, as shown by its brown tips and margins.

Once or twice a week, especially in the winter when interior air is dry from heating, use a mister. To improve moisture intake, group your peace lily with other plants. Place the pot on a tray filled with wet pebbles or put it in a humidifier.

Improper Fertilization

Excessive fertilizer application or concentration may lead to brown and damaged foliage. Moreover, a nitrogen shortage causes leaves to turn yellow, brown, and regrow.

Using a diluted, balanced fertilizer (like NPK 20-20-20) no more than once every six weeks is the maximum frequency of feeding your plant during cultivation. Start feeding towards the end of winter and dilute the suggested strength by up to 50%.

Incorrect Light

Dappled light is ideal for peace lilies, and they can survive for as little as two to four hours per day. The big leaves become discoloured when they receive excessive direct sun exposure.

Put your plant wherever it will get bright, indirect light. A suitable location is next to, but not in front of, an east-facing window.

Peace Lily Watering Tips

  • Put your finger on the first knuckle of the soil. If it appears to be dry, you ought to water it. An alternate method is to use a moisture meter.
  • Utilize deionized water or leave tap water out for a day or two to let impurities evaporate.
  • When the water runs out of the drainage holes, place your peace lily in a washbasin and let it run. When placing the plant back in its saucer, drain any excess.
  • If water flows through the pot without soaking into the soil, your plant may be root-bound. Pot it up into a vessel that is an inch or two bigger.
  • Water your peace lily right away if it begins to wilt and turn yellow. Usually, the plant becomes friendly.

Need to cut the brown leaves of the peace lily?

It’s common for leaves to turn brown at the ends or edges, so feel free to trim the tips off with sharp scissors, taking care to keep the leaf’s natural tapering point intact. Brown-edged leaves should be removed entirely since cutting them produces an uneven shape.

Remove the smaller brown leaves as well. Don’t remove too many huge leaves because older leaves naturally die back. Pruning back more than one-third of the plant at a time is the general rule of thumb.


Taking care of peace lilies is more work than taking care of a child. All inside jokes aside, you need to look into the causes of the damage if you possess a peace lily and are worried about it growing.
