It’s very disappointing we know-

It’s upsetting to see your cherished Peperomia plant suffer mainly because the cause of this is most likely your bad decisions and carelessness.

Your minor errors are why your plant is sick right now if you don’t properly care for it!

But we will assist you in resolving this!

To assist you, we have outlined your errors and their solutions-

 1. Faulty in watering Faulty in watering

Peperomia are native to tropical and subtropical regions of the world, in particular Central America. They prefer water when the soil is dry out. If you water your Peperomia before the soil dries out, it means you are watering more water.

 It can also cause your Philodendron leaves to turn into brown spots. But always remember Philodendron love moist in their soil but not wet.

So, how much water do Peperomia plants need? 

Well, Peperomia plants do not require a lot of watering. They need to be Watered every 1-2- weeks; this will allow the soil to dry out between waterings. Look for the signs of overwatering-

Overwatering of peperomia plants can be rotting stalks, wilting or yellowing leaves, a heavy pot, and waterlogged soil. We would recommend, typically only, water peperomia plants every 7-10 days. But- 

You might have to water the plant more-

If you live in a dry climate or where the average winter temperature is 28-39 degrees Fahrenheit. Summer temperatures range from 69 to 78 degrees Fahrenheit. More specifically, we say watering the plant every morning.

You won’t be overwatering the plant this way. Even if you didn’t know, overwatering would cause the plant’s roots to rot. Brown spots appear as a result of this situation.

It is also essential to check the soil before watering again. Because if your drainage system is in poor condition-

Watering daily raises the risk of brown spots on leaves.

Solution

Don’t worry if you made a mistake when watering the garden! Instead, remember how to care for the plant right now!

To begin, you must examine the soil to decide whether you have under or overwatered the plant. If the soil is hot, you’ve overwatered the plant. And it wasn’t able to absorb everything.

So, pick up the plant and place it in a different container or pot. At least 3-4 drainage holes should be present in the pot. Be patient after the replanting. And there is water that needs to be drained.

Once you’re sure, enough water has been drained, test the soil. Use a moisture meter to know whether the soil is moist or not. If it is, you can start watering again. Now, if you touch the soil and it’s scorched. That means you haven’t provided enough water. 

If you water your Peperomia at a specific time, the leaves will begin to emerge from the brown spot.

But from the other side, there is an easy way to water your Peperomia: stick your finger in the soil at least an inch deep, and if you cannot adhere your finger in a simple form in the soil, it means your philodendron needs water.

2. Insufficient Humidity electric humidifier

When growing a Peperomia Plant, one of the most important factors to consider is humidity. Low relative humidity (less than 50%) is ideal for Peperomia plants. And it is for this reason that they can function in environments such as homes and workplaces.

When the surrounding air becomes drier, the problem arises. The moisture in the plant is quickly depleted. Wilting and browning of the leaves will occur if that amount of water is not replaced. That is why, in addition to proper soil watering, ensure that there is sufficient humidity.

Solution

You can spray the air around your houseplants and directly on the plants with a simple spray bottle. Some moisture will vaporize directly, raising humidity, while most will fall on your plants’ leaves and surrounding surfaces.

An electric humidifier may also be used. These can be tiny and inconspicuous, and they can be switched on and off to produce the ideal amount of humidity in a space for you and your plants.

A pebble tray is an easy way to increase local humidity for one or a few plants in an otherwise arid climate. Place your houseplant pot on top of the pebbles to be safe and not submerged in water.

3. Too Much use of FertilizerJulyPanny Soil pH Meter

Now, too much fertilizer use is the first reason why the plant has brown spots on leaves. 

A Peperomia plant prefers a pH level of  6-7. The brown spots on leaves mostly appear due to the greater pH level in the soil. 

So, if a plant lacks this nutrient-

They’ll stop growing, and their leaves will brown spots. Moreover, they’ll simply die if you don’t act quickly. 

How can you be sure there is being used of too much fertilizer

Stunted growth, dried or burnt leaf margins, wilting breakdown, or plant death are all signs of over-fertilization. The most severe threat to fertilizers is “burning.”

Fertilizers contain high amounts of various salts, and humidity from their sources can be extracted using a process known as reverse osmosis.

When the surface content of salt is greater than that of the plant’s soil, and the plant is at risk of chemical burning and dehydration, reverse osmosis occurs.

Just read the instructions of the kit and test your soil. This tool will let you know how much of the nutrient is missing in no time.

How to save the Peperomia plant? 

To be honest, it’s not that hard to turn the situation back to normal. Therefore, just follow our lead-

Firstly, remove the affected leaves. We suggest cutting the leaves where their stems have begun. This way, you can prevent damaging the plant’s tissues.

Once you’ve discarded the brown spotted leaves-

Grab yourself a soil testing kit. Which will help you determine how much fertilizer you might need to add.

We’ve mentioned these tools-

4. Insufficient Lighting & Wrong TemperatureLED Grow Light for Potted Plants

Inadequate lighting and temperature will destroy your plant over time. These unsanitary living conditions aren’t only to blame for brown-spotted leaves. But also for turning Pothos black

Peperomia plants now grow in bright environments. This plant needs 6-7 hours of direct sunlight every day. They should be exposed to an LED light for at least 8 hours. Since this plant cannot produce food in the absence of light. This inevitably results in the brown mark on the leaves.

It is now also important to check the temperature. During the day, the plant should be kept at a temperature of 65-70 degrees Fahrenheit. At night, the temperature drops to 55-60 degrees Fahrenheit. As a result, it is preferable if the lighting is given by the temperature range.

Excessive or inadequate lighting and temperature are also disliked. And too much heat will cause the leaves to burn. A lack of light and temperature can cause the plant to starve. As a result, the purple leaves would be visible on the vine.

5. Infestation of InsectsInfestation of Insects

Insects can definitely be a reason behind those Brown Spots on leaves. Because they are well known for sucking the juice out of the leaf tissue. And this causes a plant’s leaves to lose chlorophyll.  

Now, you’ll mostly see spider mites, aphids, and thrips around your Peperomia plant. Because these three love Peperomia.
