    Growth rate

    Peperomia plants are popular as houseplants because they are small and compact. Indoors, most Peperomia plants will stay small, usually not exceeding two feet in height.

    How to care for Peperomia Obtusifolia


    For optimal growth, the Baby Rubber Plant appreciates bright light but can also tolerate lower light conditions, including fluorescent lighting. While indirect bright light is ideal, this plant can tolerate artificial light better than other plants. Avoid exposing it to direct sunlight, as it may require more frequent watering in brighter conditions.


    The Peperomia Obtusifolia prefers warmer temperatures and appreciates humidity, although it can still thrive without extra humidity. It can tolerate temperatures above 10 degrees Celsius, but rapid drops in temperature may result in leaf drop. The ideal temperature range is between 18 and 30 degrees Celsius.

    To protect baby rubber plants from frost, bring them indoors during winter or keep them in a sheltered area with no strong winter winds. Also, mulch them well.

    Watering requirement for Peperomia Obtusifolia

    In terms of watering, this plant is low-maintenance. Its succulent-like leaves retain water, allowing it to tolerate longer periods without watering. It is better to underwater than overwater. Wait until the top 5 centimeters of soil are dry before giving it a thorough watering. The watering frequency may vary depending on your location’s conditions. In summer, watering every fortnight is common.

    Repotting Baby Rubber Plant

    Potting and repotting Peperomia plants is a simple process. These plants like to be root-bound in small containers and can survive for many years without needing to be repotted. However, when you start seeing roots coming out of the drainage holes, it’s time to move them to a slightly larger container. Choose a pot that is only a couple of inches bigger than the current one.When repotting, use an acidic potting mix or orchid bark to provide the right nutrients for the plant. This will help it thrive in the new container.

    Humidity requirement

    Baby Rubber Trees can tolerate most household humidity levels. However, they will grow faster when the humidity is over 60 percent. Increase humidity for these indoor tropical plants by using pebble trays with water, grouping plants together, or using a cool-mist humidifier.Peperomia obtusifolia can reach a height of 24 inches when grown indoors, with proper care. Pinch back leggy growth to maintain a full rubber plant.

    Fertilizing Baby Rubber Plant

    Feeding the Baby Rubber Plant is essential for its growth and health. A complete NPK type fertilizer with a wide range of minerals, including calcium, is recommended. Avoid urea-based nitrogen fertilizers to prevent fertilizer burn. Adjust the feeding schedule according to the plant’s growth rate and season, with slower growing plants requiring a quarter dose every feed in spring and summer.

    Perfect Soil

    Using a free-draining soil is recommended for this plant. It should not have “wet feet,” so a lightweight and airy soil mix, such as a peat-based mix, is suitable. Thanks to its water-storing leaves and shallow root system, repotting is not necessary frequently. Some plants have thrived for up to 3 years without repotting.


    Peperomia plants don’t often flower when kept indoors, but sometimes they do. The flowers are small and unscented, appearing as spindly spikes in brown and greenish-white colors. They may not look like typical flowers and can even detract from the overall appearance of the plant. If you prefer, you can cut off the flowers at the base of the shoot or wait for them to naturally wither and fall off.


    In early spring, lightly prune Peperomia plants to fix any thin or weak growth. Pinch the stems just above a leaf node to encourage more branching and make the plant look fuller. You can use your fingers or pruners to remove the end of each stem and the first set of leaves.

    Propagation of Peperomia Obtusifolia

    You can propagate Peperomia plants at any time, but it’s best to do it in spring or summer when the plant is growing more actively. If you plan to prune your plants in spring, you can take a stem cutting with extra growth and use it for propagation. Here’s how:

    • You’ll need sterile pruning snips or scissors, a small pot, potting soil or orchid mix, plastic wrap, and a well-lit area.
    • Cut off a leaf with at least an inch of its stem from the mother plant.
    • Place the cutting, with the cut end down, in a small container filled with potting soil. Put it in a bright spot with indirect light and cover it with plastic wrap to create a mini-greenhouse and retain moisture.
    • Water the cutting regularly and make sure the soil doesn’t dry out. Within a few weeks, roots will form, and you can transfer the cutting to a larger container when it outgrows the original one.

    Growing Peperomia From Seed

    To grow Peperomia from seed, you’ll need a soilless seed starting mix, enough water, and a warm, sunny location with indirect sunlight for the seeds to germinate. Keep the soil consistently moist until germination occurs. Once the young seedlings are ready, transplant them into a container and place the plant in a bright area with indirect sun. Note that if you collect seeds from your plant, the new plants may not be exactly like the parent, especially if it’s a hybrid cultivar. Propagating from cuttings ensures that the young plants are identical to the parent

    Finally, the Peperomia Obtusifolia is pet-safe, making it a great choice for households with pets and children.

    Common Issues

    Like other houseplants, Peperomia plants can be susceptible to common pests such as mealybugs, spider mites, and whiteflies. If you notice any infestation, insecticidal soap can be used as an effective treatment.

    Here are some pro tips and problem-solving techniques for the Baby Rubber Plant:

    • Slow growth is normal for this plant, so don’t worry if it is growing slowly.
    • If you notice sparse or leggy growth, pinch off a growth tip to encourage bushier growth and fill in the bare area.
    • Changes in leaves may be caused by overwatering or cold temperatures. If the soil is not too wet, try moving the plant to a warmer spot.
    • Wilting leaves can be a sign of both overwatering and underwatering. Check the soil to determine the cause.
    • Brown, crispy leaf edges may indicate under-watering or salt build-up and potassium deficiency in the soil. Consider using a urea-free fertilizer and reevaluate watering practices.
    • Curling leaves are often a result of under-watering.
    • Yellowing or black stems can be a sign of overwatering and root rot, which should be addressed promptly.
