How to Care for a Baby Rubber Plant

Peperomia obtusifolia care is as simple as it gets, which is one of the best things about the plant. A little bit of TLC can make this plant flourish, even if you’re not a seasoned gardener. 

Baby Rubber Plant: Watering and Light Requirements 

The Peperomia obtusifolia plant is not demanding and does not require a lot of attention when it comes to its watering and light needs.

How Often Should I Water My Baby Rubber Plant?

As it can retain water in the leaves, the baby rubber plant doesn't demand frequent watering. It’s slightly drought-tolerant and you can water it every 7-10 days. Check the soil and ensure that the top 2" are completely dry before you water it again 

Do Baby Rubber Plants Need a Lot of Light?  

The baby rubber plant needs indirect light. It can survive in low light, though medium bright light is recommended. Place it in a spot with partial shade or on a window sill facing the west or east where it'll receive soft morning or late afternoon sunlight. Excess sunlight can scorch your Peperomia plant.

Baby Rubber Plant: Soil & Fertilizer 

If you want your baby rubber plant to be healthy, pay attention to its soil and fertilization needs. Ensure that it gets sufficient nutrients to grow and flourish.

What Kind of Soil Does Peperomia Obtusifolia Like?

The Peperomia obtusifolia prefers light, slightly acidic, well-draining, and organically rich soil. An orchid potting medium is a great choice, though you can also use regular potting soil with an equal mix of peat moss and perlite, or coarse sand. 

Do Baby Rubber Plants Need Fertilizer? 

Baby rubber plants are low feeders. So, fertilizing them too often can cause nutrient toxicity, harming the short roots. Restrict the fertilization sessions to 3 times a year in the spring, summer, and fall. Allow your plant to rest during winter. Use a 10-10-10 water-soluble fertilizer. 

How Often Should I Repot a Baby Rubber Plant?

Repotting a Baby Rubber Plant

When you first bring home a new baby rubber plant, wait 6-12 months before repotting it. After that, you can replant it once every two years. 

It's best to transplant the plant during spring. It has a slow growth rate and doesn’t mind being slightly root-bound and snug in its pot, so it doesn't require frequent repotting. 

However, move it to a larger pot when the roots poke out of the drainage holes. It indicates that the roots don't have sufficient space to grow. 

A planter 2” larger than the current one should be sufficient. An excessively large container will keep the soil wet for too long, causing root rot. Also, remember to remove dead or rotting roots before transplanting your baby rubber plant in fresh soil. Water the soil thoroughly, but don’t make it soggy.

Baby Rubber Plant: Temperature and Humidity 

The baby rubber plant enjoys moderately warm regions and medium humidity. It thrives in hardiness zones 10-12. 

What Temperature Do Baby Rubber Plants Like?

The baby rubber plant is comfortable in a temperature range of 60°F-75°F. That means it will be happy in the standard indoor temperature in a US home or office. It doesn’t handle cold well and mustn't be exposed to temperatures below 55°F.    

Do Baby Rubber Plants Like to Be Misted?

Baby rubber plants love to be misted regularly, especially in dry spells of weather. This keeps their surroundings warm and humid. It’s best to grow this plant where the humidity level is 40%-50%.

Baby Rubber Plant: Pruning 

As mentioned, Peperomia obtusifolia plants have a slow growth rate. Still, pruning them will help you maintain their shape, appearance, and health. It’s best to prune the plant during the growth seasons, in spring and summer.  

Should I Prune My Baby Rubber Plant? 

You should prune your Peperomia to remove any discolored or damaged leaves. A good time to trim the baby rubber plant is when you water it. Use the opportunity to give it a better shape and bushier appearance.

How Do You Shape a Baby Rubber Plant?

Pruning is a good way to give your baby rubber plant a fuller look, but only if you do it right. Cut the leaves above the nodes (the point from where leaves grow) to encourage branching. This will control the overall shape of your plant’s foliage. 

Peperomia Obtusifolia: Propagation Techniques 

How to Propagate a Baby Rubber Plant

Propagation helps multiply your baby rubber plant collection. You can propagate your Peperomia obtusifolia from stem or leaf cuttings in both soil and water. 

Where Do You Cut a Baby Rubber Plant to Propagate?

If you want to use a stem cutting for baby rubber plant propagation, pick a 4”-6” long stem with at least 3 leaves and cut below the node. Remove the bottom leaves if needed. For leaf propagation, pick a healthy leaf and cut it along with the petiole above the node.

How to Propagate a Baby Rubber Plant 

To propagate baby rubber plants in soil, you can use a stem or leaf cutting. Let the cut end heal before dipping it in rooting hormone powder. Then, insert the cutting in the potting mix, pressing the soil around it. Water the stem or leaf cuttings and cover them with transparent plastic to create the right humid conditions

To propagate your Peperomia plant in water, you’ll need a stem cutting. Once its cut end heals, put it in a jar with filtered water and allow the roots to develop.
