How to Care for Peperomia Argyreia (Watermelon)?

Peperomia argyreia, more often known as watermelon peperomia, is a species belonging to the Peperomia genus that is quite popular. It was given the name watermelon because of its superficial resemblance to the rind of a watermelon.

How to Care for Peperomia Argyreia (Watermelon)

Peperomia Argyreia has skyrocketed in popularity among houseplant aficionados thanks mainly to its strikingly beautiful leaves, which are patterned like a watermelon. They like to grow in a tight cluster, and their bright, shimmering leaves seem lovely when illuminated by the sunlight. In its native South America, the watermelon peperomia is a tropical plant species. Although their typical habitat is the shaded ground of rainforests, these plants thrive in the bright light of a greenhouse.

How to Care for Peperomia Argyreia (Watermelon)?

Watermelon peperomia thrives in warm, somewhat humid conditions. Still, typical indoor temperatures & humidity levels are just suitable for these tropical plants. If you have peperomia, keep it away from drafty windows and vents, so the air around it doesn’t dry out.


Pick a spot for the Peperomia argyreia that gets bright to moderate indirect light. This will help the plant thrive. Because their leaves are prone to burning, they should not be subjected to lengthy periods of direct sunlight. They can live in settings with less light, but their leaves will become more diminutive, and their growth will become more spindly.


These Peperomia argyreia do well in most conventional potting mixes as long as they allow enough drainage and retain moisture. Steer clear of soil explicitly designed for plants that thrive in arid environments, such as cacti and succulents, because this type of soil does not take enough water to keep the plant alive. Peat moss & perlite combined in a ratio of one to one will also work for growing watermelon peperomia.


The Peperomia argyreia can only grow in the humid conditions of the tropical rainforest if the soil is kept moist at all times but never allowed to get saturated. Similar care should be taken with the watermelon and Peperomia plants in your home watering.

You should water your watermelon Peperomia whenever the top inch of soil becomes fully dry. Slowly saturate the soil with warm water until it has absorbed as much as possible and the excess drains away from the base. The watermelon Peperomia would do better with distilled water or natural rainfall than with the tap water available in your water due to potentially harmful contaminants. If you must drink tap water, let it lay out overnight so the fluoride and chlorine can evaporate.

Temperature and Humidity

Warm, somewhat humid conditions are ideal for watermelon peperomia. As a result, tropical plants may thrive in the typical home’s light and humidity temperatures. You should move the peperomia away from drafty vents or windows, as these locations tend to have drier air.


A light amount of fertilizer in the spring and summer benefits the Peperomia argyreia, but it is unnecessary. Fertilizing Peperomia argyreia with a 20-20-20 liquid houseplant fertilizer is ideal for its fertilizer and development.

It is imperative that the liquid formula for Peperomia argyreia fertilizer be diluted to just half of what is indicated to guarantee proper application. Quickly and evenly pour the soil over the top of the soil once you have soaked it. That way, you know the body is absorbing everything evenly.

Once in a while, a thin coating of white crust would form on the soil’s surface. This signifies that fertilizer salts have built up in the soil and might injure the plant’s roots. Salts in the soil can be flushed out by irrigating them with a continuous stream of water for about 10 minutes.

Potting & Repotting 

Peperomia argyreia only has to be repotted every two to three years because it grows slowly and tolerates being rootbound. When roots develop from drainage holes, repot the watermelon Peperomia. When transferring it, simply expand the pot by one size because too much soil might limit its growth.

Find a new draining container. Use glazed or unglazed earthenware or a sturdy plastic pot. Use freshly-made potting soil. You may not need to move pots, but you must still use new growth material.


All the Peperomia argyreia pruning you’ll ever need is to take off the diseased or dead leaves. This plant’s aesthetic value is diminished and can provide a safe home for pests and illnesses. The watermelon peperomia, or peperomia for short, is a slow-growing plant that naturally forms a dense bush without pruning or another tending on the grower’s part.

When collecting Peperomia argyreia leaves, remove the entire stem from the ground up to where the leaves are located. No new leaves will form on a withered stem. In time, new stems will sprout and reveal a new crop of leaves. To keep the soil free of chopped leaves, use sharp, sterilized scissors while pruning your Peperomia argyreia.

Peperomia Argyreia Propagation

Leaf cuttings are the most typical and straightforward method for propagating this particular species of peperomia. Before sowing in seedlings plus cutting compost, you should remove leaves with their petioles (stalks) and apply rooting hormone to the cut. Keep the soil wet and warm by leaving a stalk about one inch long with at least one leaf on it.

To propagate Peperomia Argyreia by division, proceed as follows:

  • To begin, take the entire plant and remove it from the potting container. This will allow you to study the roots and gently separate the offshoots.
  • Identify the offshoots of the plant that you wish to separate from the main plant (it is recommended that you keep offshoots less than 1 inch in length in the original container), and then carefully pull the roots away from the main plant.
  • Plant the just severed branch in its container, and then thoroughly water the soil.
  • After the seeds have been separated, plant them in an area exposed to indirect light that ranges from medium to bright, and maintain an even level of moisture in the soil for the first one to two weeks.
  • After a few weeks have passed, you’ll be able to resume your typical watering routine.

Common Problems of Peperomia Argyreia

The watermelon Peperomia, like many houseplants, is more vulnerable to problems if inadequate conditions are provided for its growth.

Regarding Peperomia argyreia, most problems may be easily identified and fixed. A plant’s leaves can provide clues about its general well-being, so if they start to wilt or look unhealthy, it’s time to find out what’s wrong.

Pests & Diseases

These plants are sensitive to various common illnesses and pests affecting houseplants. Several different pests might cause problems for Peperomia argyreia. Some pests are sap-sucking, such as scales, aphids, and mealybugs. This peperomia is also susceptible to rot caused by root rot if they are overwatered, and if their watering is not adequately regulated, they can acquire the condition fast.

Peperomia Argyreia Curling Leaves

The presence of crinkled leaves on a plant is typically an indicator that the plant is being overwatered or that the leaves are being subjected to excessive direct sunlight.

Peperomia Argyreia Leaves Are Falling

If the leaves on your plant are beginning to droop, it may be because it lacks water and needs to be hydrated. In most cases, this can be immediately remedied by giving the plant good watering.

Peperomia Argyreia Leaves Turning Brown

Several factors could contribute to the browning of the leaves on your peperomia, including recent changes or stresses in the environment, damage caused by pests, inadequate humidity, excessive watering, and a lack of humidity (if they are brown and mushy). Consider your plant’s setting and the type of care it receives, and decide which of these two categories best describes you.

Peperomia Argyreia Leaves Turning Yellow

An overwatered watermelon peperomia is the most likely culprit when leaves begin to turn yellow. To prevent this, you should allow the soil to dry for a short period in between waterings and ensure adequate drainage. Pests are another potential cause of the yellowing of the leaves.

Why do my watermelon peperomia’s leaves have long stems and little leaves?

An indicator of a healthy watermelon peperomia is a bushy appearance attributable to the plant’s large, glossy leaves. Leggy growth, caused by an absence of light, is characterized by long, floppy stems and few unimpressive leaves. Put your peperomia in a more brightly lit area to promote robust, healthy growth.

How can Peperomia Argyreia develop more quickly?

The Peperomia Argyreia plant will develop rapidly if placed in the brightest possible position but shielded from direct sunlight while the temperature is high. Adding more fertilizer won’t make the plant grow more quickly.

How quick is the growth of watermelon peperomia?

You’ll notice white roots emerging in about 6 to 8 weeks. Plant in soil, then enjoy once a few roots have reached 3 to 4 cm.

Peperomia Argyreia can tolerate how much cold?

The watermelon Peperomia plant can tolerate temperatures as low as 50 degrees Fahrenheit (10 degrees Celsius). Still, below that, it will begin to lose its leaves, and temperatures that drop below freezing will cause it to die.
