  4. Press the soil around each leaf to ensure that the leaf is firmly in the soil. Water the plant, once a day for three days, you can do this using a spray bottle.

Although caring for your plant seems simple, a lot of people, unknowingly, make life-threatening mistakes with some of their care routines. The following guide will teach you just how to care for your plant the right way, and also help you strike a balance between overdoing it and underdoing it.

1. Light

To keep its colors and beauty, the peperomia quadrangularis will appreciate being provided sufficient light. Keep in mind that these plants are outdoor plants; hence they love their environment to be well-lit. However, they cannot tolerate being placed where the direct rays of the sun will hit them.

We recommend that you expose them to bright, indirect, or filtered light throughout the day. Ensure that they are not placed in the shade as this will make them lose their color, variegation, and beauty.

If you find your plant to be pale, yellow with few leaves, as well as a leggy stem, it is an indication that your plant isn’t receiving as much light as it should. You can place these plants by the south, west, or east window during the day.

If you will be growing them outdoor, you should place them behind other plants, the other plants will filter the sun before it gets to the quadrangularis.

2. Water

The peperomia quadrangularis will not appreciate overwatering or under-watering. The good thing is that this plant is similar to succulent, which means it can store water in its leaves and stem, hence you can water it as one. It also loves rainwater and likes that its soil is kept moist but not soggy.
