Radiator Plants (Peperomia) can be propagated in four easy ways; from seeds, from leaf cuttings, from stems cuttings and by plant division. The cuttings root easily and usually, there is no need for a rooting hormone. The cuttings can be rooted in water or in soil.
The best time to propagate Radiator Plants is during the growing season when the plant is actively growing. At this time, the plant has enough food reserves which are necessary for faster establishment.
Peperomia (Radiator Plants) grow best in bright, indirect light and moderately moist fertile, well-drained soil coupled with monthly feeding during the growing season. They prefer warm, humid conditions for lush growth. Check out our post on Peperomia (Radiator Plants) Indoor Care, Common Problems and Remedies
We have outlined herebelow 4 easy Radiator Plants (Peperomia) propagation methods. Keep reading for a detailed account on these methods.
Peperomia Plants seed propagation; Some Radiator Plants do flower and produce seeds which can be used to propagate new plants. The seeds are also readily available from growers.
Radiator Plant seeds germinate easily. Fill a seed starter tray with a seed starting mix, sow the seeds and water moderately.
Place the set up in a warm shaded place and maintain the soil moist until the seeds germinate.
Once germinated, move the set up to a warm, well-lit place and maintain the soil moist until the new Radiator Plants are well established.
When the seedlings are about 6-8 inches and have 6-10 leaves, transplant into individuals pots in moist, free-draining soil after which you can begin routine care.
Peperomia Plants leaf propagation in water; Radiator Plants leaf cuttings root easily and there is no need for a rooting hormone.
Take leaf cuttings from a healthy Radiator Plant and ensure each leaf cutting has a petiole as this is where new growth will come from.
Allow some time for the formation of a protective callus tissue over the cuts of the leaf cuttings to prevent rotting.
Place the leaf cuttings in a jar of clean plain water or in a propagation station and change the water every 5-7 days.
Place the set up in a warm, well-lit place until growth begins at the base of the cuttings leaf petiole. Allow enough time for substantial growth of the roots and new leaves.
Transfer the rooted cuttings to individual pots in moist, free-draining soil. For a fuller plant, transfer several cuttings in one pot.
Place the pots in a warm, well-lit place. Maintain the soil moist until the new Radiator Plants are well established after which you can begin routine care.

Peperomia Plants propagation from stem-tip cuttings; Radiator Plants stem cuttings root easily and usually there is no need for a rooting hormone.
Take stem cuttings of about 4-5 inches length from a healthy Peperomia Plant and ensure each cutting has at least 2 sets of leaves. Strip off the lower leaves.
Allow some time for the formation of a protective callus tissue over the cuts of the cuttings to prevent rotting.
Fill a rooting container or pot with a free-draining soil. Moisten the soil lightly.
With a pencil or anything similar make a hole in the center of the container. Ensure that the hole is wider than the diameter of the cutting.
Once callused, insert about 2-3 inches of the cutting in the previously made hole. Gently tap and firm the soil around the base of the cutting.
Cover the set up with clear polythene to increase humidity and warmth but allow space for air circulation to prevent the cuttings from rotting.
Place the set up in a well-lit and shaded place; avoid direct sunlight as it can cook the plants.
Maintain the soil moist until new growth emerges and there is substantial growth.
Remove any dead foliage to maintain the set up clean and avoid disease infestation.
When, you observe substancial growth, transfer the rooted Radiator Plant stem cuttings to individual pots in free-draining soil. For a fuller plant, transfer several cuttings into one pot.
Thoroughly water the soil until the water comes out through the drainage holes.
Position the pots in a warm, well-lit place and begin routine care.

Peperomia Plants propagation by plant division; Water the Radiator Plant thoroughly at least 1 day before to make it easier to divide and also hasten establishment. A well hydrated plant suffers less shock and takes a shorter time to take root.
Take the Peperomia Plant out of its pot and carefully divide it into sections by pulling apart the roots. Ensure each section has adequate roots to hasten establishment.
Select a 6 or 8 inches pot and ensure that the pot has a drainage hole to prevent the soil from getting soggy as it can lead to rotting.
Fill the pot with free-draining mix and make a hole in the center of the pot. Ensure that the hole is slightly wider than the root base of the Radiator Plant section.
Place the section in the previously made hole and lightly firm the soil around the base while taking care not to bury it too deep; maintain the section at the same soil level it was in the previous pot.
Water the soil thoroughly and place the set up in a warm, well-lit place away from direct sunlight.
Maintain the soil moist until the new plant is well established after which you can begin routine care.
