Watermelon peperomia is the next plant you need to add to your collection of indoor plants because of its resemblance to a watermelon and its purple stalks. Before you claim that you have enough indoor plants, remember that there is never enough. Here is our comprehensive grower’s guide to watermelon peperomia.
Peperomia argyreia, also known as watermelon peperomia, got its name because of how much its leaves mimic watermelon skin. It is native to South America and grows up to 30 cm tall, making it perfect for the Australian climate and tiny areas. This plant is in the easy-grow category and is actually fantastic for beginners with green thumbs.
During the spring and summer, flowers may occur, albeit the slender stalks more closely resemble spikes than flowers.
Care Instructions
There are a few easy guidelines to follow in order to maintain your watermelon peperomia’s happiness and health:
- Keep them in a well-lit area away from direct sunlight.
- Water them sparingly—just enough to make the soil mildly damp, not more.
- Once or twice a year, give them a light natural fertilizer feeding.
- These guys don’t need to be repotted too often because they enjoy growing very compact.
Is watermelon peperomia a simple plant to maintain?
Overall, watermelon peperomia are simple to cultivate and care for as indoor plants, especially if you are good at remembering to water them. This plant might not be for you if you frequently neglect to water your plants for weeks at a time because peperomia love moisture.
Watering Watermelon Peperomia
These plants are more prone to overwatering than underwatering because of their thick leaves, which trap moisture, but they might have issues from either. While preventing the soil from drying up completely, you should also let the soil air out in between waterings.
Before watering, it’s a good idea to allow the top inch or two of soil at the plant’s base dry out. You can anticipate needing to water once every 1-3 weeks in the summer and once every 3-5 weeks in the winter depending on a variety of conditions.
- Light A plant’s soil will dry up more quickly the more light it receives.
- TemperatureHigher temperatures cause greater perspiration, which need more frequent watering.
- Humidity
- You’ll need to water less when the humidity rises.
- GrowthDuring the winter, plants consume less water because their growth slows.
Fertilizing Watermelon Peperomia
Although these plants don’t require very complex nutrients, they will benefit from regular application of houseplant fertilizer.
A typical indoor houseplant fertilizer should be diluted to half the specified concentration. From late spring to early fall, fertilize your plant with this mixture every few months. During the winter, fertilizing is not necessary.
Pruning Watermelon Peperomia
These tiny plants don’t require pruning, but you can trim them whenever you think their growth is getting out of hand. Cut the plant’s stems with a pair of clean, sharp scissors.
Propagate by Division
- Obtain an established plant. You’ll need a plant with developed roots and at least a few leaf clusters.
- Take the soil out. Remove the entire plant from the container with care. Shake the dirt off to reveal the roots.
- Divide the roots. Once you have a clear view, use a sharp knife or set of shears to separate the roots. Each piece should have a root and at least one leaf.
- Replant. Put one of your divisions into each pot that you have. As with adult plants, water in and take care of.
Propagate from a Stem Cutting
- Cut something. Obtain a leaf cutting that includes at least one inch of the red petiole (leaf stem).
- Submerge in water. Put the cutting in a container and cover the petiole base with water. There shouldn’t be any water on the leaf.
- Wait. Every week, change the water, then watch for roots to emerge.
- Pot. When roots appear, you can plant the cutting in a pot with potting soil that drains well.
Propagate from a Leaf Cutting
- procure a cutting. These cuttings don’t require a leaf node for successful propagation, in contrast to many other plants. Make a precise cut that is parallel to the leaf’s stripes in order to obtain a cutting.
- Put in the ground. Cut side down, plant the cutting in the ground. The only part of the cutting that should be buried is the very tip.
- Mist and cover. To boost humidity, place a plastic bag or container over your cutting and spritz with water.
- Wait. Within a few weeks, your cutting should start to grow roots. Keep the humidity high during this period, but stay away from moist ground.
Light/Exposure
Mine is growing in light that is moderately bright. It is eight yards from a window that faces south and gets no direct light.
This particular plant does well with lesser light levels. No growth if the light is too low. Burn if in a scorching sun.
In order to provide your Watermelon Peperomia with the necessary light during the colder winter months, you might need to transfer it to a brighter location. Here are some more suggestions for winter plant care.
Watering
I can’t tell you how frequently to water yours because there are different factors at play, like the size of the pot, the soil mix, the environment of your home, and the area where it’s growing.
Water your Watermelon Peperomia generally when the soil is 3/4 dry. You should water more frequently in the summer and less frequently in the winter.
I water mine every five to six days during the summer months because of the intense sunlight, heat, and low humidity levels in this area. Every 7 to 12 days during the winter. Depending on the environment where you live, you might not need to water yours as frequently.
Water is stored in the dense leaves and succulent stalks. Keep yours from getting too damp to prevent root rot.
The bottom of the pot should ideally have 1 or more drainage holes so that any extra water may drain out.
As you can see, this plant takes on a somewhat open and airy look as it grows. The Watermelon Peperomia flowers are on the wine-colored stalks on the left that are tipped with pale green.
Humidity
Peperomias enjoy humid environments because they are native to subtropical and tropical areas. In spite of this, the ones used for houseplants are typically humidity-adaptable.
The humidity is 11% as I write this in mid-April. To put it mildly, it’s dry, and my watermelon pepperomia is doing great!
In my living/dining area, I have a humidity reader. It works well and is inexpensive. When the humidity falls below 30%, which occurs frequently in Arizona, I turn on my tabletop humidifiers.
Every month I also give my peperomia a bath in the kitchen sink and, when the summer rains come, I leave it outside for about an hour.
Try placing your plant on top of a saucer that has been filled with small rocks and water if you believe yours is under stress due to humidity. Be careful not to submerge the drain holes.
Additionally, you can mist your peperomia a few times per week. Here is the tiny sprayer that I have been using for more than 3 years and it is still in excellent condition.
My Peperomia obtusifolia, Peperomia caperata, and Peperomia Raindrop. Various, but they all have lovely leaves.
Fertilizer
I apply a little amount of worm compost/compost to all of my houseplants (apart from air plants, bromeliads, and orchids) every spring. Avoid using too much; a 1/4-layer will do for a 6-pot batch. Every time you water, it gently decomposes and seeps into the soil.
Throughout the warmer months, I water my peperomias with Eleanor’s VF-11 three or four times every week. Due to the 2022 supply chain issue, online orders of this product are currently delayed, however if you can’t get it locally, keep checking again.
Alternatively, I also feed with Maxsea three to four times year. Here, the growing season is lengthy, so my plants appreciate and require the nutrients.
Other choices are Joyful Dirt and this kelp/seaweed fertilizer. Both are well-liked and get favorable ratings.
For your peperomia, fertilizing twice a year might be sufficient. Because many fertilizers are heavy in salts and can eventually burn plant roots, avoid overfertilizing (using too much of a ratio or doing it too frequently).
Soil/Repotting
The best times for repotting are spring, summer, and early fall, much like for fertilizing and feeding.
For all the information and a step-by-step guide, see this post and video on Peperomia repotting.
Because they stay compact and don’t grow quickly, watermelon Peperomias only require repotting every five years, providing they aren’t stressed out from being potbound. Just increase the size of the pot by one. By way of illustration, from a 4 to a 6 grow pot.
In a nutshell, I make my own succulent and cactus mix using a 1:1 potting soil mixture. The latter has coco coir and chips, which peperomias adore and is a more ecological alternative to peat moss. I add a couple handfuls of compost as well, and then I sprinkle worm compost on top.
In the page, you’ll also find various soil mixtures appropriate for repotting peperomia.
Pruning
With this plant, little pruning is necessary. I only remove a fading or dead bottom leaf once or twice a year.
In contrast to its cousin, the Baby Rubber Plant, it does not trail and develop inward. No need for pruning because it maintains its compactness.
You can notice how this peperomia develops more compactly and tightly in comparison to the Watermelon Peperomia, which is more open.
Propagation
I’ve never divided or taken stem cuttings from a Watermelon Peperomia, but I do have Peperomia obtusifolia.
By using stem cuttings in water, my friend successfully propagated a Watermelon peperomia. I’ve read that leaf cuttings can also be used to propagate it.
Pests
Pests have never invaded my peperomia plants. Because of their soft leaves and stems, I can see how they would be vulnerable to mealybugs. Watch out for spider mites as well.
Pests can quickly spread from plant to plant and multiply over night, so it’s important to take control of them as soon as you notice them.
Flowers
They do, indeed. On the tips of stems with a wine-colored tint, the tiny, green flowers are arranged in clusters. Your Watermelon Peperomia will flower if it is in good health and is content.
I have a few more pepperomias. Peperomia Hope is the plant in the white metallic container, and Peperomia Rainbow is the one just behind it.
How does Peperomia Watermelon become bushy?
It’s easy to fix the problem. Move your lanky watermelon peperomia to a more well-lit area. The already stretched leaves won’t get any shorter, but the new growth will be fuller and bushier.
Remember that direct sunlight will injure your plant when you move it to a brighter spot, especially in the summer when it will sear the leaves. A window that faces east or west is great since the plant will receive enough light during the day. Remember once again that summer solar rays can injure your plant even in this place.
This plant grows well under artificial growth lights if natural light is not an available.
Since peperomias don’t generally grow quickly, it can take some time for your plant to develop a bushy appearance.
Is peperomia a healthy houseplant?
Since peperomia have so many characteristics that make them perfect houseplants, they are wonderful plants to cultivate indoors. They are perfect for anyone wishing to add to their collection of houseplants because they tolerate a wide range of growing conditions and have a wide variety of lovely foliage.
How Should a Peperomia Plant Be Cared For? The majority of Peperomia plants require temperatures between 65 and 80 °F and bright, indirect sunlight. They should be potted in well-draining potting soil, watered sparingly after the top inch of soil dries out, fertilized every month throughout the growing season.

Is it better to water pepperomia from the top or bottom?
The choice to avoid constantly wetting the leaves is entirely up to you, especially if the water doesn’t dry off right away. When you water from the bottom, the soil is evenly moistened and the ideal volume of water is absorbed. Make sure the water reaches the root level if you water from the bottom. Some peperomias grow better when watered from the bottom, while others grow better when watered from the top. Try both and decide which is preferred by you and your plant.
If you choose to water your peperomia from the bottom, another thing to keep in mind is that doing so won’t remove the salt and mineral accumulation from the soil. For that reason, it is occasionally advisable to water from the top.
Is Watermelon Peperomia Misting Necessary?
Misting your plants is an excellent technique to enhance the humidity in the air for them. The leaves of your Watermelon Peperomia will be able to access the moisture more easily if you regularly wet them.
The only drawback to spraying your plants is that it adds another responsibility to watering them that you must remember. Because of this, some people choose to use a humidifier.
Why is the Peperomia on my watermelon dying?
Overwatering or the roots being exposed to excessive amounts of water in any other way are the most common causes of a Watermelon Peperomia dying. In general, peperomia plants prefer to dry out between waterings and dislike being overwatered. Although this is the most frequent problem, there are other causes as well, such as underwatering, inadequate light, excessive light, and low or fluctuating temperatures. To try to determine the cause of your Watermelon Peperomia’s demise, let’s look at each of these problems individually.
