How to Care for Your Rubber Plant (Ficus)
Read in: 6 min
The popular Ficus Rubber Tree is a moderately easy-to-care for flowering plant known as “Elastica” does produce a milky and white latex sap, but it is not where rubber comes from. The rubber plant that produces the rubber we use comes from the “Hevea Brasiliensis” plant. While the rubber producing plants native to Southeast Asia can grow up to 100 feet tall, and Benjamina can grow up to 60 feet tall in the wild, houseplant Rubber Trees only grow between 2 and 10 feet tall indoors.
The lack of height comes from the way we raise the Rubber Tree plants including root restriction, a non-natural growing environment, and the selective breeding done by collectors, nurseries, and horticulturalists.
Knowing the natural environment that the Rubber Tree plant comes from has an advantage, it lets you create a similar habitat in your home so it can have the lush, waxy, and rich colored foliage like it is growing in the wild. And that’s what this guide will teach you.

Where Rubber Tree Originates
Rubber Tree Ficus Plants come primarily from the tropical rainforests in Myanmar, India, Malaysia, and Indonesia in Southeast Asia. Some species of Ficus Elastica can even be found in the tropical regions of Nepal.
Through the years they’ve been cultivated and gained the ability to grow in temperate climates meaning there are four seasons and no extreme weather like you’d experience the freezing conditions and year-round winter in Antarctica or their native tropical regions with endless summer weather.
In the wild the Ficus species of Rubber Tree (the one we have as houseplants) can grow between 40 and 60 feet tall on average as they have their ideal environment with plenty of humidity, warmth, and have clay based soils rich in iron and aluminum oxides giving it a yellow and reddish color. The soil also tends to be highly acidic due to the heavy rains and quick decomposition of organic matter like fallen leaves and branches.
The good news is the cultivations have made it easier to create environments where your houseplant version of the Rubber Tree can thrive without needing the acidic soils and hot temperatures. But they will need some specifics that help them grow like humidity, and we provide easy ways to do this so your Rubber Tree plant can grow healthy and lush in your home below.

Rubber Tree Plant Care Instructions
Caring for your Ficus Rubber Tree houseplant is easy with these instructions.
Watering
Add water to your Rubber Tree plant’s potting mix when the top one to two inches are dry. If you are not sure how dry the potting mix is, either test it with your finger or use a water meter for the most accuracy.
Sunlight
Ficus Rubber Tree plants need between 6 and 8 hours of bright but indirect sunlight each day so keep them near windows facing south east or west when possible. The gentle brightness of golden hours are ideal for them where the harsh noon sun can cause leaf burn.
Humidity and Temperature
Keep humidity levels between 40% and 60% for your rubber tree to thrive and a temperature range of 65 to 85 degrees Fahrenheit. The average home has a humidity range of 30% to 50% depending on the season, and you can measure your home’s level with a hygrometer.
If you fall below the 40%, use a pebble tray under your Ficus Rubber Tree or group it with other plants to increase the humidity around it.
Health Issues to Look For
Rubber Tree houseplants are hardy, but they do face issues when exposed to the wrong environments.
Leaf Spots
When you notice brown or black spots on the leaves of the Rubber Tree it is normally a sign of bacterial, fungal (mold), or viral infections. Fungicides may help with bacterial, viral and fungal infections on your Rubber Tree plant, and you’ll want to trim the infected leaves and change the potting mix. It wouldn’t hurt to make sure there is enough air circulation in the area, especially if it was mold.
Discoloration
When you notice the leaves have become less vibrant or discolored, this is normally due to over or under watering, or an incorrect amount of sunlight. First check the potting mix and make sure it isn’t too wet or too dry. You want slight moisture.
If it is too wet change the potting mix and reduce the frequency you water your plant. If it is too dry add a bit of water and increase the frequency of waterings to 1 to 2 times per week. Watch to see if it begins regaining its vibrancy over the next couple of weeks.
If the cause was too much or too little sunlight, move it to an area of your home where there is more or less natural light. This can change seasonally and based on the direction the window is facing.
Sun and Leaf Burn
If the leaves turn brown and get crunchy, your Rubber Tree Plant likely has leaf burn. Trim the brown parts off and move your plant further away from direct sunlight.
Root Rot
Root Rot for Ficus Rubber Trees shows up in the form of yellow leaves (unless the variegation was yellow). If you suspect root rot, carefully remove the plant from its potting mix and rinse the roots clean. If they are mushy and yellow or have a foul smell, cut the rotting roots off with sharp and disinfected shears.
Next rinse the root system off under clean running water and disinfect the pot it was in. Now re-pot your Rubber Tree plant in fresh potting mix.
Potting Mix and Nutrition
Use well draining and aerated potting mix for Ficus Rubber trees with perlite, pumice, or vermiculite for draining and coconut core for aeration. Try our Coco bag if you want to take the guesswork out as it is designed specifically for Ficus and other plants that need aeration and moisture control.
The Types of Rubber Tree Plants
Although there is only one natural type of Ficus Rubber Tree for a houseplant, there are countless cultivars. Here are a few of our team’s favorites.
Ficus benjamina
Also known as the Weeping Fig, Ficus benjamina has slender, arching branches and small, glossy green leaves that give it a soft, tree-like appearance. It prefers bright, indirect light and steady conditions—sudden changes in light or temperature can cause leaf drop. Ideal for corners or bright rooms where you want a classic, airy look.
Ficus elastica ‘Ruby’
This colorful rubber plant features thick, glossy leaves with shades of pink, cream, and green. Ficus elastica ‘Ruby’ thrives in bright, indirect light to maintain its variegation and needs infrequent watering. It adds a bold, tropical vibe to modern interiors and does best when allowed to dry slightly between waterings.
Ficus benjamina ‘El Dorado’
A variegated cultivar of the Weeping Fig, El Dorado features creamy yellow and green marbled foliage. Its upright, airy growth habit is similar to the standard benjamina, but the coloring adds extra visual interest. Best suited for bright spaces with consistent lighting and minimal drafts.
Ficus elastica ‘Tineke’
Tineke is a popular variegated rubber plant with broad, creamy-edged leaves and splashes of green throughout. It's a slow-growing variety that prefers bright, indirect light to maintain its variegation. Low-maintenance and striking, it's perfect for well-lit living rooms or offices.
Ficus elastica ‘Robusta’
This variety has wide, deep green leaves that are thicker and glossier than the standard rubber plant. Ficus elastica ‘Robusta’ is highly adaptable and easier to grow than more finicky ficus types. It works well as a low-effort statement plant in both home and commercial spaces.
Ficus shivereana
A rare rubber plant variety with pale green to minty leaves speckled with darker green or cream. Ficus shivereana has a more subtle, marbled appearance than Tineke or Ruby and thrives in bright, indirect light. Its muted coloring makes it ideal for neutral or softly styled spaces.
