How to Grow, Care and Prune Peperomia Angulata (Quadrangularis)

The Beetle plant, Peperomia quadrangularis, is well-known among houseplant lovers for its distinctive ovate, green leaves. It looks lovely in hanging baskets and can reach a height of 12 inches.

What Is Peperomia Quadrangularis?

Peperomia Angulata (Quadrangularis)

Peperomia quadrangularis (also known as Beetle peperomia, Radiator plant, and Peperomia angulata) is a Piperaceae family tropical perennial shrub. It’s a South American plant that thrives in Brazil and Panama.

It may be used as a trailing plant in containers or as a ground cover. It also thrives in terrariums as a ground plant cover. Peperomia quadrangularis, which is sometimes mistaken for a succulent, requires more humidity and care than a succulent.

Peperomia Quadrangularis Plant Care

Size & Growth

Peperomia quadrangularis has thick, dark green variegated foliage, making it an excellent addition to any indoor plant collection. Peperomia quadrangularis, a creeping peperomia species (like Peperomia perciliata), is a simple plant to cultivate.

When trailing, they can reach a length of 12 inches. The leaves of Peperomia quadrangularis are striped, oblong, dark green, and grow up to 1 inch in length.

Flowering And Fragrance

Quadrangularis has lovely white blooms that resemble a boot or an ice-pop. Spring and summer are the plant’s flowering seasons.


This plant need a lot of light to survive, and although though it’s an outside plant, it won’t withstand direct sunlight, especially in the summer. It may grow in moderate to low light, but the color of its leaves will fade.

It may be grown outdoors if it is shaded by other plants or cultivated beneath a garden net to keep the leaves from being burned by direct sunshine.

Water And Feeding

Because this plant is similar to a succulent in that it stores water in its leaves and stems, you should water it similarly. The plant should not be overwatered, nor should it be allowed to dry out completely.

Water it once a week, just enough to keep the soil wet and allow water to drain. Prevent waterlogging of the roots, since root rot is the most common cause of mortality due to inadequate drainage and/or over-watering.


Because it is native to tropical settings with moderate/high humidity, controlling/maintaining a range of 40-50 percent humidity is critical in caring for this plant. Occasional sprinkling will assist boost the humidity, especially in arid conditions.

If you want to grow it in a temperate area, keep it away from heaters and air conditioners since they dry up the air. In the winter, methods like using a humidifier to preserve humidity are included.


For optimal growth circumstances, it prefers temperatures over 60°F, but it can take typical indoor temperatures. While it is known to endure a wide range of temperatures, temperatures below 50°F will cause its leaves to drop off. This plant may be grown outside in tropical climes.

Soil & Transplanting

For rapid growth and development, the plant requires well-draining wet potting soil with a pH of 5.5–6.5. Its growth necessitates the use of light fertilizers.

Grooming And Maintenance

Peperomia quadrangularis is a low-maintenance plant. Trimming the plant every two months will enough to keep it in good shape. Even if trimming isn’t always essential, you’ll need to keep an eye on the plant’s size if it’s reached 15 inches or more.

You should only prune damaged leaves, stems, and foliage since severe trimming can harm the plant and prevent its growth.

How To Propagate Beetle Peperomia

Peperomia quadrangularis can be propagated from leaf cuttings. Remove the large leaves of the plant with their petioles (stalks).

Place the cutting in a warm, light location and bury the leaves in moist houseplant potting mix. You will see the growth of the new plant.

Peperomia Quadrangularis Uses

Peperomia quadrangularis is a popular houseplant, ground cover, and hanging basket that is easy to cultivate. It may be grown in container gardens – just make sure you have the right pot size – and kept on a desk or window sill by plant enthusiasts.

Many people grow peperomia in hanging baskets to embellish their outdoor lounging areas, such as a pergola, because it is a creeper plant. In a terrarium, plants can also grow wild.

The plant may grow both terrestrially and epiphytically in a vivarium. Many people, on the other hand, use them as an epiphyte, like an epiphyllum orchid cactus. This plant is well-liked for its attractive leaves and ability to fit into small places. It’s a lovely ornamental plant that requires very little upkeep.

Additional Care

This plant reacts well to being treated once a month throughout its growing phase using a fertilizer diluted thrice the specified dose – for example, if the dose is 5ml per gallon of water, dilute it to 5ml per three gallons of water, or use balanced and diluted cacti/succulent fertilizer. During the winter, do not feed.

If you don’t want to use chemical fertilizers, you may replace the top few inches of soil in your garden with organic manure every month or two.

Repotting Peperomia Quadrangularis

Peperomia quadrangularis has a shallow root system, which allows it to thrive in small pots for long periods of time. They prefer to be tethered to the ground. However, this does not imply that it prefers to be in extremely compacted soil. The soil should have some perlite or gravel in it and be well-draining.

Winter is the optimum time to repot Peperomia quadrangularis. It’s time to repot when you observe the leaves becoming yellow and dull, or the roots coming out of the drainage hole, and the plant has stopped growing. Select a pot that is one size larger than the previous one.

Do not disrupt the roots of your plant when repotting it, and add fertilizer to the soil to boost the nutrition level. If you assume that repotting your plant would make it bushier and bigger, you’re probably incorrect. Peperomia quadrangularis can’t grow much more than 12 inches.

Propagate the current plant and put the cuttings in the same container to make the plant denser and bushier.

Common Problems

  • While bugs and pests seldom attack this plant, it’s a good idea to include an organic pesticide spray of neem oil or insecticidal soap in your maintenance regimen just in case. If pests are discovered, thoroughly clean the leaves and treat them with insecticidal soap or neem oil.
  • Avoid splashing the soil with water while misting, and don’t soak the leaves and stems for too long, as this plant is susceptible to stem rot.
  • Fading and/or drab Insufficient light is most likely the reason of the plant’s leaves. Make sure it develops in bright, shady light.
  • Whether you detect quick and rapid leaf drop, investigate the plant’s base to see if it has been afflicted by root rot. The stems get moist and discolored around the roots nearly usually indicates this.
  • Root rot can be devastating, especially if the plant is young, and there isn’t much you can do to save it from dying. You can, however, clean the roots and remove the rotting areas of the roots if the plant is older and mature with many branches. Reduce watering in general and repot the plant in newly aerated soil.
  • If plant development has been restricted or stunted for an extended period of time, it may be time to repot the plant in new nutrient-rich soil and maybe enhance lighting conditions.
  • Under-watering is frequently the cause of your plant’s limpness and droopiness. Simply give it plenty of water and see if it recovers. Severe under-watering can cause the roots to die completely, and the plant will not recover when it is irrigated. The only way to save the plant is to try to propagate it.
  • Leaf discolouration and leaf loss are caused by exposure to cold weather. Check the temperature right away, and if it’s too cold, move the plant to a warmer spot.
  • Yellow leaves indicate a lack of nutrients; feed the plant with a diluted balanced fertilizer and keep an eye on the leaves. Repotting it with extra organic manure mixed into the soil is another option.
