Peperomia obtusifolia, which is also known as the American Rubber plant, is a hardy succulent that can decorate any home or garden.

It is low maintenance, and it stores its water in its leaves, that’s why they’re so thick.

Peperomia Obtusifolia Care & Growing Guide

1. Light requirements

Direct, intense sunlight is not ideal for this plant. The best type of light is direct morning light, followed by full indirect light. It also does well under artificial light. If planted in the shade or kept away from indirect light, the peperomia will experience leaf drop as well as faded coloring.

2. Water

Because the peperomia is part of the succulent family, it doesn’t need frequent watering for it to survive and grow. Always check to see in the soil around the plant is dry before you re-water it because it is a desert plant. It is worse to leave it too wet than too dry. 

3. Climate

The peperomia loves climate that is warm but humid. It is a topical and desert plant, so moisture in the air is a necessity. You can dry the plant with water if you have a warm house. It can also be at home in a greenhouse, where there are constant heat and humidity.

4. Soil

The best kind of soil for peperomias that are in pots is a soil that is mixed with perlite and peat moss. The soil cannot be clumpy or hold onto water, and it must drain quickly. If it is outdoors, then the soil needs to be chunky enough to allow rainwater to drain and have low acidity.

5. Temperature

Peperomia plants do not do well with temperatures that dip below 30F. It is used to some cold weather, but not snowy or rainy weather. They are mostly tropical plants that love humidity and warm heat. 

They can survive hot heat if they’re not in direct sunlight, but they should be kept below 80F. 

6. Repotting

Because of the Peperomia’s slow rate of growth, it does not need to be repotted every year. When you do repot them, choose a container that is no more than two inches wider than the pot they were in before.

Furthermore, only repot it when you see the rots coming out from the bottom. Combine its current soil with other soil that is slightly acidic.

7. Speed of Growth

The peperomia doesn’t grow quickly at all. Throughout the entire growing season, you’ll barely see this plant grow up to 12 inches if all of the conditions are right. 

Because they don’t experience much growth, they tend to be placed on the windowsill. Cold weather does stunt their growth, so watch out for the temperature wherever the peperomia is placed. 

8. Height and spread

This is a relatively small succulent plant. It can grow up to 2 to 2 ½ feet in height, whether it is indoors or outdoors. But this plant usually grows to around one to two feet in height.

It’s spread can differ depending on the rate of trimming, but if it can take a while to grow out. It’s spread is 8-12 inches across, which is great if you want to put it on a desk or table.
