Water Peperomia quadrangularis thoroughly when the top 2-3 cm of soil feels dry. Allow excess water to drain completely. Avoid overwatering, as this can lead to root rot.

Reduce watering frequency during the cooler, dormant winter months, letting the soil dry out more between waterings.

Prune Peperomia quadrangularis to maintain its shape and encourage bushier growth. Pinch back the tips of stems occasionally. Remove any yellowing or dead leaves promptly to keep the plant healthy and attractive.

Pruning can be done at any time, but is most beneficial during the active growing season.

Propagate Peperomia quadrangularis through stem cuttings or leaf cuttings. Take 5-10 cm stem cuttings with at least two nodes, removing lower leaves. Alternatively, use a healthy leaf with its petiole.

Both methods can be rooted in moist potting mix or water, with cuttings typically rooting in 3-4 weeks.

Repot Peperomia quadrangularis every 2-3 years, or when it becomes root-bound. Choose a pot that is only slightly larger than the current one.

Use a well-draining potting mix, such as a cactus or succulent blend, to prevent waterlogging. Repotting is best done in the spring.
