Fixing Brown Leaves on Monstera with Simple Solutions

Plant lovers all over keep Monsteras as the crown jewels of their decor collection. But when those big, beautiful leaves start turning brown, suddenly, the shine fades, and it’s no longer a sight to behold.

But fear not, my friend! I’ve got your back. I’ve structured this article so we can team up and figure out the culprit behind the brown leaves together. And remember, misdiagnosing your plant is like giving it a one-way ticket to plant heaven.

We’ll go through all the possible care blunders that cause brown leaves on your Monstera, and before you know it, we’ll have your Monstera back to its former green glory.

Solving the Mystery of Brown Leaves on Monstera

The spots on Monstera leaves may result from various causes. Typically, improper watering or sunburn triggers the browning of leaves.

However, it is also normal for the plant to shed its lower leaves during its aging process. In such cases, there is no need for concern.

Nevertheless, if a problem causes the brown leaves, it is imperative to take prompt action to save the Monstera from potential death.

Brown discoloration can sometimes sneak up on the tips of your Monstera’s leaves and spread like wildfire, taking over the entire leaf.

But don’t worry; it’s not a monster (a-ha!) problem; it’s just a slight discoloration. So, what’s causing this brown takeover? But first, let’s take a closer look.

Monstera Leaves Have Brown Leaves with a Yellow Halo: A Mite Attack!

Don’t let dry and warm conditions welcome these pesky visitors, make sure to give your plant a daily shower and spritz it with black soap once the leaves dry.

If you take a closer look at the back of the leaves, you might even see the attackers. Time to break out the water guns!

Give your plant a good shower daily and spray it with black soap as soon as the leaves dry. Repeat for about five days, and the mites will run for the hills.

But wait, there’s more! You can also bring in reinforcements in the form of Phytoseiulus persimilis, the mite-eating superhero.

And for all, you greenhouse enthusiasts, Amblyseius Montdorensis, the mite predator, and blue sticky strips make a great team to keep your crops mite-free.

Just create a barrier by placing long blue sticky stripes around your Monstera tables.

Just a heads up, mites can be a bit tricky, and your Monstera is a sensitive plant. Keep an eye on it, especially if it’s near other plants. And if you can’t find a quarantine area, just make sure to observe it often.

Solving the Browning Blues in Your Monstera Variegata

Monstera variegata's white leaf areas may brown due to environmental stressors like high light exposure, drought, or nutrient deficiencies.

If you’ve got a variegated monstera and its white parts are turning brown, don’t panic. This happens to the best of us.

Remember, your Monstera is weaker than a classic monstera deliciosa because it’s got white areas instead of green!

You must give it more love and attention to keep your variegated Monstera looking its best. Make sure it’s close to a window for some indirect sunlight, but not too close, or you’ll fry it with direct rays!

Also, cut back on the nitrogen in its compost and fertilizer because too much is terrible for its white areas.

Keep your Monstera away from any drafts and temperature fluctuations. And if you want to keep its white parts looking their best, ensure it’s always at 60% humidity.

Spraying it often or putting it near a humidifier will do the trick. So now, go forth and keep those white parts looking white!

The Monstera’s Brown Leaves: Placement Pitfalls

Monstera plants need bright, indirect light near a west or east-facing window to grow well and avoid browning

Site conditions play a significant role in making that happen. But watch out; too little light, scorching sun, and dry air can cause those leaves and leaf tips to turn brown faster than you can say “jungle giant.”

Monsteras come from the lush forests of Central and South America, where they climb tall trees using their liana-like tendrils and thrive in the soft light of the jungle canopies.

To survive and thrive, these plants avoid dark spots near the ground and hot, direct tropical sun.

So, the closer you get to mimicking their natural habitat, the more vibrant, healthy, and richly colored your Monstera’s leaves will be.

If you suspect site deficiencies are the cause, move that baby to a better location, and the problem is solved!

These plants can get too little light in the winter, and a lack of light, blazing sun, or dry air can quickly cause brown leaves or leaf tips.

These tropical beauties also don’t tolerate cold or temperature fluctuations, so watch out for those drafts when airing your home.

And remember, the Monstera may handle darker locations, but it will grow slower and lack those signature incisions.

Finding the Right Placement

The key to healthy, vibrant leaves is mimicking your living space’s natural conditions. Place your Monstera near a west or east window for best results.

If you have a south-facing window, just make sure to provide some shade in the afternoon to filter out direct sun rays.

In the summer months, from June to September, feel free to bring your leafy friend to the sunny balcony – just make sure to protect it from the blazing sun.

Keep your Monstera warm and cozy by avoiding cold temperatures. Aim for temperatures between 68°-82°F from April to September and 64°-70°F from October to March.

Keep humidity levels as high as possible, and steer clear of drafts. Opt for a bright to semi-shaded location, away from the blazing sun, with a minimum distance of 6-9 feet from the window or wall.

Note: Constant contact with windows or walls can also cause brown leaves. Keep a safe distance to prevent any damage.

Prevent Your Monstera’s Leaves from Turning Brown with Proper Hydration!

When your Monstera isn’t getting enough water, it can’t spread the H2O love to all its parts, and presto! The leaves turn yellow, then brown, wilt, and eventually bite the dust.

Don’t worry; checking the moisture level is a breeze. Just poke your finger an inch into the soil; if it feels like the Sahara desert, your plant needs some hydration.

And if the humidity is too low, you’ll see brown tips and edges on the leaves. Remember, monsteras are rainforest dwellers and love a good humidity of 50-60%.

So, how do we keep our Monstera hydrated and happy? Here are a few tips:

  • Give it a good drink in the summer and just enough in the winter.
  • Keep the soil moist but not soaking wet.
  • Use warm, plain water.
  • Spray the leaves with lime-free water regularly.
  • Keep the air moist and away from dry heat.
  • Use humidifiers and hygrometers to monitor humidity levels.
  • Dip its aerial roots into a container filled with water.
  • If needed, fully immerse the root ball in the water.
  • Place the root ball in a bucket with water until no more air bubbles rise to the surface.

And that’s it! With these tips, your Monstera will be green and thriving in no time!

Waterlogging = Brown Leaves for Your Monstera. Here’s What to Do

Excessive waterlogging causes root rot, disrupting nutrient absorption and leading to brown leaves due to chlorophyll decline.

Waterlogging can be a real bummer for your Monstera, causing more harm than a temporary drought. When the soil stays too wet, it becomes compacted, and the roots can’t breathe, leading to suffocation.

That means the roots can’t transport water and nutrients to the rest of the plant, causing brown tips and edges on the leaves, not to mention root rot.

To prevent waterlogging, be mindful of over-watering, using large quantities of water, clogged drainage holes in the pot, or standing water in the saucer. If you do encounter waterlogging, take action!

Here’s what to do:

  • Gently remove the Monstera from its pot.
  • Remove the wet soil.
  • Rinse the roots with lukewarm water.
  • Cut off any brown or diseased roots.
  • Clean the pot with hot water.
  • Ensure that the drainage holes are unblocked.
  • Add a 2-inch layer of expanded clay, shards of clay, or gravel at the bottom of the pot.
  • Fill the pot halfway with fresh soil.
  • Place the root ball in the pot.
  • Fill the remaining soil, making sure not to bury the plant deeper than before.
  • Leave a 0.75-inch margin for watering.
  • Wait one week before watering, then water regularly, but allow the top of the soil to dry a bit between waterings.
  • Remove excess water from the saucer.
  • Use a moisture meter for optimal results.

Note: If you see the light brown spots with a darker edge on the leaves, it’s a sign of sunburn. Move the Monstera to a spot with partial shade to avoid direct sunlight.

Don’t Let Your Monstera Suffer from Nutritional Deficiency or Overdose!

If your Monstera’s leaves start turning yellow and falling off, it’s time to check the nutrition levels. Too much fertilizer can also give you brown leaves, as the roots get burned and the leaves wilt, yellow, brown, and finally die.

Don’t let overfertilization ruin your plant! Undiluted liquid fertilizer is a big no-no. The only solution is to repot in fresh soil. To keep your Monstera healthy, remember to give it a balanced diet:

  • Monstera has moderately high nutritional needs
  • Fertilize every two weeks from March to September with a liquid fertilizer for houseplants
  • Dilute according to the manufacturer’s instructions
  • Stick to fertilizer sticks for houseplants if you’re not into liquids
  • Take a break from fertilizing from October and onwards

Pro Tip: Give your Monstera leaves a spa day with seaweed juice. This will give them a subtle shine and supply the necessary vitamins, minerals, and nutrients!”

Monstera Leaves Turning Brown Due to Fungal Diseases

Are your Monstera leaves turning brown with round, light spots with a darker edge?

Unfortunately, it sounds like your plant has caught the notorious Eye Spot Disease (Spilocaea oleagina), also known as Peacock Eye because these spots resemble the feathers of a peacock. But don’t panic just yet, we’ve got you covered!

The pathogen spreads slowly, regular inspections are crucial to detecting this disease early and saving your plant from great damage.

The fungus owes its name to brown Monstera leaves with light halos that spread over the entire leaf. It’s time to fight back!

Here’s what you need to do:

  1. Cut off infected leaves and say goodbye to them in the trash can.
  2. Disinfect your scissors with spirit before each cut. No one likes a germaphobe, but in this case, it’s better to be safe than sorry.
  3. Treat re-infected areas with a copper-based fungicide.
  4. Don’t let it spread! Do not put the diseased leaves on the compost heap.

Since Eye Spot Disease spreads slowly, removing infected Monstera leaves may already be enough to control it. But why take chances?

Treat the leaves with a copper-based fungicide and watch as your Monstera bounces back to its healthy, beautiful self. It’s time to show this fungus who’s boss!

Sunburn Prevention for Your Monstera: Avoiding Brown Leaves with the Perfect Light

Are your Monstera leaves turning brown? Could it be sunburn? Yes, it’s possible! Monstera plants love partial shade, but a little bit of direct sunlight is good for them.

However, too much direct sunlight, especially during midday, can cause sunburn. Don’t worry, we’ve got your back!

Check out our guide to finding the perfect location for your Monstera, where you’ll learn all about the optimal light conditions for your plant.

Summertime is when sunburn occurs most often, and it usually affects the leaves that are further away from the roots, which receive less water and are more susceptible to sunburn.

Young Monstera plants are also more vulnerable to sunburn than old plants.

If your Monstera has suffered sunburn, it’s time to move it to a new location with partial shade. A water bath can also help it normalize its water balance. At the very least, make sure to water it vigorously once.

The Humidity Solution: Avoid Brown Leaves on Your Monstera:

Did wintertime get you down? Is your Monstera sporting some unsightly brown  leaves? Blame it on the low humidity!

If you’re seeking ways to ensure your monstera flourishes through the winter, then this article contains all the essential information you need.

Heating air and lack of ventilation can make the humidity in your home drop, causing your Monstera’s leaves to dry out and turn brown. But don’t worry; we’ve got a few tricks to help.

First, make sure to avoid placing your Monstera directly next to a heater, as the humidity in that area is the lowest.

Spraying your plant with water three times a day can increase humidity, but who has time for that? Instead, consider grouping your houseplants to create a microclimate with higher local humidity.

Or, you can use a humidifier to bring the humidity to a subtropical level that’s perfect for your Monstera.

Say goodbye to brown leaves and hello to a happy, healthy Monstera plant!
