How to Care for Peperomia obtusifolia indoors?

Peperomia obtusifolia requires regular pruning to keep it neat and minimize pest and disease infestations. Repotting is only needed when the plant becomes pot-bound. Keep reading for more on these growing conditions and how to achieve them.

Watering

How often should I water Peperomia obtusifolia?

Water Peperomia obtusifolia liberally in spring and summer and allow the top 2-3 inches of soil to dry out between waterings. Maintain the soil moderately moist and avoid soggy soil to prevent rotting, drooping, yellowing and leaf drop.

Reduce watering in fall and winter to keep the soil barely moist as growth is minimal at this time. However, do not allow the soil to dry out completely for a long period to avoid wilting, drooping, yellowing and leaf drop.

Use room temperature water as consistently watering with too cold water can result in slowed growth and leaf drop due to cold shock. Ensure the water is free of chlorine and other dissolved chemicals to prevent browning of leaf edges.

Confirm that the pot has a drainage hole and the soil is well-draining to prevent waterlogging which can lead in root-rot and death of the plant. Avoid wetting the foliage to minimize fungal diseases.

Light Requirements

Where is the best to put Pepper Face Peperomia?

Pepper Face Peperomia grows best in bright indirect light; put it near a bright, sunless window which receives 6-8 hours of light. Keep it away from direct sunshine to prevent discoloration of the leaves.

Baby Rubber Plant can tolerate medium to low indirect light for a short period. However, bright light is necessary to maintain the bright and intense color of the leaves especially for the variegated types. If the natural lighting is too low, use a full spectrum grow light to supplement it.

Once monthly, give the pot a 90⁰ turn, to ensure that the plant receives light on all sides for even growth and also prevent leggy growth.

Temperature & Humidity

Pepper Face Plant thrives in a warmth of 18-25⁰C; temperatures that are comfortable for you are good for these plants.

Keep Baby Rubber Plant away from sources of drafts like AC units, radiators, windy doors, drafty windows and others, to prevent temperature flactuations which can cause reduced growth, wilting, drooping, yellowing and leaf drop.

Peperomia obtusifolia prefers a humidity of 50-55%; it has no need for extra humidity. However, if the air is too dry it can result in brown leaf tips and edges. To elevate humidity, set the pot on a wet pebble tray, use a humidifier or group the plants together. Ensure good air circulation to reduce fungal diseases.

Fertilizer

What is the best fertilizer for Peperomia obtusifolia?

Feed Peperomia obtusifolia with a balanced, water-soluble fertilizer every 4 weeks in spring and summer to promote a lush growth.

Do not feed in fall and winter as growth is slowed and feeding at this time may lead to fertilizer burn and death of the plant.

Potting Soil

What kind of soil does Peperomia obtusifolia like?

The best soil for Peperomia obtusifolia should be a rich, well-draining mix that does not get soggy while providing the required nutrients. A blend of 1 part peat moss or coconut coir (retains moisture), 1 part perlite or orchid bark (improves drainage) and 1 part organic potting mix (for nutrients) is ideal for this plant.

Repotting

Repot Pepper Face Plant during the growing season only when the plant has become pot-bound. However, you can refresh the soil at the beginning of the growing season if not repotting.

Use a pot one size larger than the current one as Baby Rubber Plant grows slowly. Ensure the pot has a drainage hole to prevent the soil from getting soggy to avoid root-rot. A shallow rather than deep pot is preferable as it has a small root system. Check out these pots with drainage holes on Amazon.

Pruning & Grooming

Pruning Peperomia obtusifolia involves:

• Regular removal of dead foliage to maintain the plant neat and tidy as well as discourage pest and disease infestations.


• Pinching off the growing tips regularly to encourage a bushy compact growth and to control growth. You may use the stem tips to propagate new plants.

Clean the leaves regularly by damp-wiping with a soft cloth to get rid of dust and also discourage pest and disease infestations.

Peperomia obtusifolia Propagation

Pepper Face Plant is propagated from leaf cuttings or from stem cuttings, in spring to early summer when the plant is actively growing.

1. Propagating Peperomia obtusifolia from leaf cuttings

The leaf cuttings root easily, therefore there is no need for a rooting hormone.

1. Take leaf cuttings from a healthy plant and ensure each cutting has a petiole.


2. Allow some time for the formation of a protective callus tissue over the cuts of the leaf cuttings to prevent rotting.


3. Once callused, submerge the leaf petiole in a jar of clean plain water or in a propagation station.


4. Change the water every 5-7 days to prevent fungal growth.


5. Place the set up in warm, well-lit spot until growth begins at the base of the cuttings leaf petiole.


6. Allow enough time for substantial growth of the roots and new leaves.


7. Transfer the new plants into individual pots in moist, free-draining soil. For a fuller plant, transfer several plants into one pot.


8. Position the pots in a warm, well-lit place away from direct sunlight.


9. Maintain the soil moist until the new plants are well established after which you can begin routine care.

2. Propagating Peperomia obtusifolia from stem cuttings

The stem cuttings root easily, therefore, there is no need for a rooting hormone.

1. Take stem cuttings of about 4-5 inches length from a healthy plant and ensure that each cutting has at least 2 sets of leaves.


2. Allow some time for the formation of a protective callus tissue over the cuts of the cuttings to prevent rotting.


3. Once callused, insert 2-3 inches of the cuttings in moist, free-draining soil.


4. Place the set up in warm, well-lit spot away from direct sunlight.


5. Maintain the soil moist until new growth emerges and there is substantial growth from the cuttings.


6. Transfer the new plants to individual pots and begin routine care. For a fuller plant, transfer several cuttings into one pot.
