How to Care for Your Baby Rubber Plant (Peperomia obtusifolia)

baby rubber plant, scientifically known as Peperomia obtusifolia, is one of the easiest and most rewarding houseplants you can grow. With its glossy, round leaves and compact size, it brings a lush tropical look to any indoor space — no green thumb required! This was one of the very first plants I got when I started my collection (obsession 🤭), and it's still going strong today, years later.

Whether you just bought one from us or are looking to keep yours thriving for years to come, here’s your complete guide to baby rubber plant care!

🌿 What Is a Baby Rubber Plant?

Despite its name, the baby rubber plant isn’t related to the large rubber tree (Ficus elastica). Instead, it’s part of the Peperomia family, a group of small, low-maintenance tropical plants native to Central and South America. The name “baby rubber plant” comes from its thick, shiny leaves that resemble rubber — but in miniature form!

This plant is perfect for apartments, offices, or any space with moderate light. It’s also pet-safe 🐾, making it a great choice for homes with cats or dogs.

There are also multiple varieties for baby rubber plants, so you can add more color to your collection! Keep in mind, the more green the leaves have, the faster the plant will grow. Plants with variegation, like the two in the pictures below, grow slower due to having less chlorophyll (remember learning about this in science class?? 🤓).

☀️ Light Requirements

Baby rubber plants prefer bright, indirect light. Too much direct sunlight can scorch their leaves, while too little light can cause them to grow leggy. I have two of mine in a north window, and they are very happy there, however, my third one is right in front of a grow light and grows faster because of this. Its flexibility with light requirements is just one of the reasons this plant is a great option for anyone, from beginners to expert level plant lovers.

Best locations:

• Near an east- or north-facing window for moderate growth
• A few feet away from a bright south- or west-facing window for faster growth and more variegation

If you notice your plant stretching or the leaves losing their shine, it’s probably asking for more light.

💧 Watering Schedule

Peperomias are semi-succulent, which means they store water in their leaves and don’t like sitting in soggy soil for too long.

Watering tips:

• Let it mostly dry out before watering again. Use a water meter if you can't easily tell when it dries out.
• Do the "taco test"🌮 - if the leaves bend easily into a taco shell, it's definitely ready for more water! 
• Always use a pot with drainage holes to prevent root rot.
• You may need to reduce watering in the winter when growth slows down.

Overwatering is the most common mistake with baby rubber plants — when in doubt, it’s better to underwater than overwater.

🌱 Soil & Potting

Use a well-draining soil mix to keep roots healthy. A combination of:

• Standard potting mix

• Perlite or pumice (for aeration)

• A bit of orchid bark (optional)

Repot your baby rubber plant every 1–2 years or when roots start peeking out of the drainage holes or you notice that it needs water a lot more often (every day or two vs. every week or two).

🌡️ Temperature & Humidity

These tropical plants thrive in average indoor temperatures (65–80°F) and moderate humidity. Keep them away from cold drafts, air vents, and heaters.

These guys aren't too picky when it comes to humidity and will do just fine even in drier climates.

🌸 Fertilizing

Feed your baby rubber plant once a month during the growing season (spring and summer) using a balanced, water-soluble fertilizer diluted to half strength. You can skip feeding in fall and winter when the plant naturally slows down, but this is optional.

✂️ Pruning & Propagation 

Pruning helps your Peperomia stay bushy and compact. Trim leggy stems or dead leaves with clean scissors.

Want more baby rubber plants? You can easily propagate from stem cuttings:

1. Cut a healthy stem with 2–3 leaves.

2. Place it in water.

3. Wait a few weeks for roots to develop before potting it up.
