6 Tips to Prevent Pothos Brown Spots on Leaves



Pothos is botanically known as Epipremnum aureum, having originated in the Pothos genus and changing names several times throughout the years. These plants are endemic to French Polynesia’s islands but have naturalized in tropical forests worldwide.

They can be seen outdoors, climbing tree trunks in their natural environments. They produce gigantic leaves in this location, rendering the plant nearly unrecognizable from what we have become accustomed to indoors.

Pothos are fantastic indoor plants due to their tropical surroundings and give a variety of benefits to our homes. But at times, due to some reasons, you may see Pothos brown spots on leaves. Let’s find out how to prevent these Pothos brown spots on leaves.

Benefits of Planting Pothos

Low Upkeep

Pothos is almost always towards the top of any list of beginner-friendly houseplants. These plants thrive in practically any indoor environment due to their tolerance for neglect. When subjected to a little stress, they retain their new appearance.

Apart from enough light, water, soil, trimming, and periodic fertilizer, these plants require little extra care. They may be placed practically anywhere in your home and will spread their lovely tendrils.

Strong Plant

Along with its modest maintenance requirements, Pothos is extremely resistant to the majority of pests and illnesses.

You can leave them practically anywhere and they will remain unchanged even if you forget about them.

As attractive as they appear, this does not imply that they are prospering or even surviving. They should not be left alone or ignored for extended periods of time in order to receive the finest care.

Pothos brown spots on leaves are a frequent symptom to watch for on your pothos plant, which often arises in less-than-ideal climatic circumstances.

Tolerates a Wide Range of Light Conditions

Indoor lighting is a nightmare to maintain. Finding the ideal happy medium that most houseplants enjoy – bright indirect light – may be challenging, even more so when you have a large number of plants to put in a small space.

That is when the Pothos enters the picture. These plants thrive under any lighting circumstances, to the point where they are frequently referred to as ‘no light’ plants. Whether put in a darker area of your kitchen or sparkling in the morning light, these plants will flourish.

However, it is critical to remember that their exceptional capacity to cope with low light does not guarantee that they will grow effectively under those conditions.

Ability to Climb

Pothos make great interior hanging plants, and their stems are frequently let to cascade over the sides of shelves or baskets.

However, few employ them in the other direction. Pothos are adept climbers and are frequently found in close proximity to tree trunks in their native environments. This feature enables them to be used and benefited in a broad variety of ways in your house.

What Causes Brown Spots on Pothos Leaves?

Excessive Watering

Pothos plants that are overwatered flourish in dry, warm settings resulting in Pothos brown spots on leaves. This suggests that excess watering is the most common cause of Pothos leaves turning brown.

Watering your Pothos will vary according to its size, placement inside the home, and environment. A smaller companion plant will require less water than a larger one.

When watering houseplants, a basic rule is to water until the soil is wet. When the water drains through the drainage hole in the bottom of your plant, you’ll know it’s sufficiently watered.

This advice also applies to Pothos plants. However, you will delay watering until the soil has had a chance to dry up.

Inconsistent Watering

While it is critical to allow your soil to dry out slightly between waterings, consistency is still critical. Take notice of the apparent timetable your Pothos plant is following and attempt to keep consistent watering.

Pothos plants are hardy and do not require extensive maintenance. However, creating a watering regimen will help prevent Pothos brown spots on leaves.

If you water your Pothos correctly and on a regular basis, you will keep your Pothos plant happy. This requires watering your Pothos until the water drains through the drainage holes on the pot’s bottom.

While the exact timing will vary for each plant, watering around once a week is sufficient. Keep an eye on your soil for the first few weeks and give it a few additional days if it is still damp at the one-week mark.

Watering Using Tap Water

You can water your Pothos plant using tap water. However, if you’ve addressed some of the other concerns and are still seeing brown leaves, peek into the water.

Tap water, in general, contains minerals, fluoride, and salt that can be detrimental to plants. While this is an improbable cause of Pothos leaves turning brown, it is worth considering it as a possibility.

Infestation by Pests

On Pothos plants, the most prevalent pests are scale insects and mealybugs. Scale insects resemble little yellow blobs with a central black mark.

Mealybugs are white, fluffy insects. Both damage the plant’s immune system by sucking its juice, which might result in Pothos brown spots on leaves.

Bacterial Leaf Spot Pothos

Bacterial leaf spot on plants can present in a variety of ways. Bacterial leaf spot can manifest themselves in the form of black-edged lesions, brown spots with yellow haloes, or simply light and dark regions on the leaves. Spots are uneven in shape and range in width from 3/16 to 12 inches (5 mm to 1 cm). They can appear on either the top or bottom of a leaf and cluster together to destroy areas of tissue. Bacterial leaf spot symptoms may sometimes emerge on the edges of a leaf, where the tissue becomes reddish yellow and eventually breaks off. When the bacterial illness infects the leaf margins, the leaves become exceedingly papery and fragile. Although the illness is most frequent on older leaves, it rapidly spreads to fresh tissue.

Bacterial Leaf Spot Pothos: Causes

Organisms that are invisible to the human eye are responsible for this visibly destructive plant disease. Wet, chilly circumstances favour the development of these bacteria, which may swiftly spread on plants. Bacteria may splash onto leaves or overwinter in soil on plant waste. Bacteria reproduce via division, and a single bacterium may proliferate rapidly in a couple of hours. Increased infection rates result in leaf loss and can adversely impair a plant’s health. As a result, the condition is exceedingly infectious, making bacterial leaf spot disease treatment critical.

How to Treat Brown Spots on Pothos?

Once you’ve identified the source of the Pothos brown tips and Pothos brown stems, you want to address it immediately to avoid the plant withering and dying. Bear in mind that if you do not sufficiently water the plant, the brown leaves might be a sign of drought.

  • Repot the plant

Typically, the first step in reviving a pothos plant that has been damaged by excessive watering is to uncover the plant and evaluate the soil on which it grows for dampness. Replace moist soil in the planter with dry, well-draining soil when you notice Pothos brown spots on leaves.

Allow the plant to rest bare-root overnight before repotting it into the fresh soil the following morning. This will assist in resolving any concerns with overwatering that may be resulting in brown and yellow leaf discoloration in pothos plants.

  • Modify your Watering Schedule

Pothos brown stems caused by overwatering is a typical occurrence for Pothos gardeners who have just relocated their plants from an outdoor site to an indoor environment. When a plant is brought indoors, its water requirements vary, since it does not require as much water to flourish as it does outside.

  • Provide an Enough Amount of Indirect Light

To prevent future leaf browning caused by excessive direct sunlight, you implement procedures to guarantee that your houseplant receives just the proper quantity of light—not too much, which can be detrimental.

For example, if your Pothos is growing near a window, you may use a sheer curtain to reduce the amount of direct sunlight it receives. Alternatively, you may relocate it to another location in the room that receives some natural light but not as much as a window area.

  • Inspect your Pothos for Plant Problems

The majority of illnesses that afflict pothos do not kill the plant, but they do alter its appearance. A popular do-it-yourself remedy for brown spots on pothos leaves and stems is to apply a fungicide containing Dimethomorph, such as BASF Stature SC Fungicide.

If you are unsure about treating the illness that is producing Pothos brown tips on your own, contact your local extension office for expert diagnosis and successful treatment.

  • Remove Excessive Salts from Fertilizers

If you believe that an accumulation of nutritional salts in the soil is generating brown leaf blotches on your Pothos, try flushing the excess salts off with water. To flush the excess fertiliser salts that are causing the Pothos brown spots on leaves, drill holes in the bottom of the planter and then pour water twice the volume of the pot into the holes. Allow the water to drain from the bottom. Repeat this procedure twice to ensure that all fertiliser and excess salts are removed from the soil.

  • Maintain an Appropriate Room Temperature

Your potted Pothos houseplants should be cultivated in a climate-controlled environment with a temperature range of 70-90°F. This is the optimal temperature, despite the fact that the plant may thrive in a variety of situations.

When temperatures are too hot or too low, beyond the range of 70-90°F, growth might be slowed and can result in Pothos brown spots on leaves.


We have discussed all the relevant points relating to the prevention of Pothos brown spots on leaves. After going through the entire article, you can figure out the reasons for Pothos brown spots on leaves and therefore, act accordingly.
