5 Common Reasons Why Peace Lily Leaf Tips Turn Brown

Even when they’re not blooming, peace lilies (Spathiphyllum spp.) are gorgeous houseplants.

Even if peace lilies didn’t blossom, I’d still grow them because of their glossy, graceful green foliage.

The only exception to this is if the leaves begin to turn brown at the tips, which is a pretty typical occurrence.

In this tutorial, we’ll go over the most prevalent causes of brown leaf tips, and we’ll explain how to fix them.

Tropic plants such as peace lilies come from Mexico, South America, and Southeast Asia where they thrive in the high humidity. Temperatures between 60 and 85 degrees Fahrenheit and at least 50% humidity are ideal for them.

However, they’re hardy enough to withstand temperatures that fall outside of this range or a lack of humidity in your home.

In less than perfect conditions, the leaves’ tips may begin to brown. In the end, the tips will never be able to become green again after this has occurred.

Either remove the entire leaf and wait for fresh foliage to take its place, or simply snip off the brown tips if you don’t like their appearance.

Let’s look at five of the most common causes of brown leaf tips on peace lilies so we can get them back on track.

1. Moisture Stress

Problems with hydration are a common cause of brown tips on peace lilies.

Too Much Water

Too Much Water When your peace lilies’ roots are unable to take oxygen from the soil because it is oversaturated, they will die.

It’s simple to assume that watering less regularly will solve the problem of oversaturated soil, however, this may not be the case.

An overwatered plant can potentially have poor drainage or grow in an extremely big container. More often than not, peace lilies thrive in a container that is just the right size for their roots and not too enormous.

Providing enough water to a plant while not oversaturating the soil around it is tough. Since the excess soil in a large pot is difficult to drain, the roots are always sitting in wet soil.

The top inch of soil should be allowed to dry out between waterings, although this isn’t usually a good indicator… Even if the top inch of soil dries up, the soil below it can stay quite wet.

Soil moisture should be checked in both half of the pot and the bottom half. Water can be added to the soil if the meter indicates that it is getting dry.

In the event that your pot is too large and you’re having difficulties keeping the soil moist, you may want to downsize or try repotting in soil with perlite or rice hulls added. Drainage will be improved, but water will still be retained.

At Arbico Organics, you may buy a quarter-, half-, or one-cubic-foot bag of rice hulls.

Poor Drainage

No matter how much water you provide, if your container has inadequate drainage, your plant’s roots will be languishing in overly wet soil for much longer than they should be.

I know how enticing it is to choose a beautiful container that does not include drainage holes for your peace lily. Honestly, I’ve tried to grow houseplants in solid containers more times than I care to confess.

In the long run, a container with at least one drainage hole in the bottom is the best option. Alternatively, an attractive cachepot can be used to conceal a well-draining container.

Even if you have drainage holes in your container, ensure sure they aren’t obstructed by debris. Put your finger or chopstick up there and move it around to your heart’s content!

Removing the plant from the container and checking for root binding is an option if you meet resistance. Make sure to loosen the roots and repot the plant in a little larger pot.

Prior to repotting a plant in the same pot, remove any rocks and loosen any clumps of soil that could be blocking the drainage hole.

After watering, always remove any saucer, pot, or other catchments from the base of your container.

Too Little Water

Oversaturation and undersaturation are equally damaging to your peace lily.

When a plant isn’t getting the water it needs, it might get stressed, resulting in dry, crisp leaf tips.

To tell if your plants are suffering from dehydration, look for signs of wilting or drooping along with the browning tips.

If you frequently submerge your plant or allow it to become dry, you run the risk of causing this condition, so don’t feel bad if you do. You should only apply water until the top inch of soil feels dry, so be sure to check it every few days.

Use some rice hulls or perlite in the potting media if the soil is drying out quickly.

A Note on Bottom Watering

It is possible that bottom watering can be an efficient approach to hydrating your plants, but this can also lead to an accumulation of sodium in the soil. Sodium is flushed out of the potting media when watered from above.

If you employ the bottom watering method, flush off any extra sodium by watering your plants from above every four or five times.

If you need to, thoroughly wet down the soil before dumping the catchment saucer on top of it, then repeat the process a second time after another 30 minutes.

The soil will remain sodium-free if you perform this procedure on a regular basis.

Never use softened water while watering your plants, and replace the soil in the container every few years to avoid salt buildup.

2. Temperature Extremes

Like other plants, peace lilies need a precise temperature range in order to develop and survive.

Although these plants like a warm, cozy atmosphere, there is such a thing as too much of a good thing. Conversely, if it becomes too cold, they’ll be in trouble (I know how they feel).

When the temperature is consistently above 80 degrees Fahrenheit and below 65 degrees Fahrenheit, the plant becomes stressed and the leaves begin to turn brown.

It’s best to either relocate your plant to a cooler spot away from windows that receive direct sunlight or turn up the air conditioning during heatwaves.

During the winter, keep plants away from heat vents as well. Aside from making the area hotter, the driven air dries the vegetation and soil more quickly.

During the winter, it’s a nice reason to crank up the heat, but you don’t have to rely just on heat. In the summer, keep plants away from AC vents and away from windows and doorways.

3. Lack of Humidity

It is common knowledge that peace lilies are native to tropical regions that are both warm and humid. The tips of the leaves may turn brown and dry if they don’t receive enough humidity.

You may boost the humidity in your home with a variety of methods. A group of houseplants can be used to enhance the humidity around your plant, or you can transfer your plant to the bathroom so it can benefit from the heat and moisture of your daily shower.

Using a tray with water and pebbles will help enhance the humidity surrounding your plant. As long as you keep the plant watered, the humidity from evaporation will help maintain the foliage green and glossy.

With a spray bottle, you may also apply a little mist to the leaves once or twice a day.

Consider purchasing a plant mister if you choose this route in order to expedite the process.

Several plants can be sprayed simultaneously with the large 27-ounce capacity of the Vivosun pressure sprayer. Amazon has them for sale, so you can get one for yourself.

Terrain also carries a beautiful copper mister that is both functional and beautiful.

Then, put on some headphones, crank up your favorite tunes, and enjoy the process of humidifying!

Alternatively, a humidifier can be purchased to raise the relative humidity in the space. Then then, it’s good for your skin’s hydration, so why not?

4. Overfertilizing

Too much fertilizer can cause sodium and other salts to build up in the soil, which is bad for plants. However, it is possible for peace lilies to suffer from this condition, as they require relatively little fertilizer.

Excess salt can be flushed from the soil more effectively by watering from the top rather than the bottom, as previously discussed. Additional support is provided by careful fertilization methods.

Indoor plant food, such as Miracle-Indoor Gro’s Plant Food, can be purchased in two-packs of 21-ounce bottles from Amazon for a reasonable price.

During the fall and winter, reduce the strength of your fertilizer to half and avoid fertilizing your plants at all.

The plant will need to be removed from its container and the potting medium knocked away if it’s too late and you’ve already applied too much fertilizer. After that, you may either use the same container or a new one to repot the plant in fresh soil.

5. Sun Scorch

If you place your peace lily in an area where it is exposed to direct sunlight, it may suffer from sunburn. Leaves will turn brown and dry at the tips of the stems.

Without changing the sun’s exposure, the leaf’s brown areas may continue to grow.

To fix this, all you have to do is transfer the plant to a location that receives less sunlight.

You may choose to install sheer curtains over the window if you prefer the plant’s existing location.

In general, northern exposure is preferable, but a window without a curtain or blind is probably too bright for your peace lilies.

Return Those Peace Lilies to Their Former Glory

Even though there are numerous possible explanations for dark tips, the solution is usually straightforward.

For the most part, all you need to do is make sure that your plant gets the right amount of sunlight and other nutrients. Check out our instructions if you need a refresher on how to grow peace lilies.
