Ficus elastica is a tropical evergreen tree that can be found in southern China, Southeast Asia, and Indonesia. It is a member of the Moraceae family of plants, and its latex sap was used to create rubber until synthetics became accessible. Hevea brasiliensis, on the other hand, produces the majority of natural rubber. Although many plants contain significant levels of isoprene, the latexy sap of these two plants has enough to be used to create rubber.
F. elastica roots are used to build live bridges in tropical Northeastern India, in addition to being helpful for rubber! The F. elastica roots are led along a dead tree trunk that has been placed over a river. The roots grow to the other side of the trunk as it rots, thickening and training new roots to complete the bridge. Because it is flexible, the bridge can withstand strong winds and flooding. This tree is very stretchy in more ways than one! Rubber trees are ideal houseplants since they are low-light tolerant and assist to purify the air.
Moraceae is a plant family that includes shrubs, trees, and lianas that all leak a latexy sap when wounded. Foliar polymorphisms are found in members of this family, which means that their leaf forms vary depending on their life stage. Most other plants produce the same leaf forms throughout their lifetimes, thus this is a peculiar trait.
Can tolerate bright direct light and thrives in medium to bright indirect light.
Allow the soil to dry out between waterings. Water every 1-2 weeks. Increase the frequency as the light level rises.
Over time, this plant will grow to a maximum height of around 30′ (10m) with a spread of about 10″ (3.2m). As a houseplant, however, it will be much smaller.
It’s a plant that’s generally laid-back. Scale and mealybugs are possible. Scale bugs and mealybugs can be treated with weekly horticultural (Neem) oil sprays and regular wipe-downs of the plant as soon as they develop.
If eaten, this plant is poisonous to cats, dogs, and humans. Houseplants should always be kept out of reach of little children and dogs.
How do I know if my rubber plant needs water?
When the plant is dry is the apparent response, but there’s more to it than that. Even indoor plants respond to variations in light and temperature. Plants receive less sunlight in the winter and become chilled. They go into a state of dormancy until more sunshine becomes accessible. As a result, you can cut your watering in half throughout the winter.
Plants placed near a fireplace or furnace, on the other hand, will have their potting soil dry out much faster. In any case, it’s time to water if the top few inches of soil are dry. You can use a water meter or simply stick your finger in the ground. At optimum moisture levels, most water meters should read a 4. During the growing season, rubber plants should be checked weekly. Yellow leaves are a warning that you are overwatering. Reduce watering somewhat at the first indication of yellowing, and healthy green, glossy leaves should appear.
Allow tap water to sit for a few hours before watering to allow chlorine to dissipate and the water to reach room temperature. This gives the plant less of a shock than ice water. Drench the soil completely with water until surplus moisture drains out the drainage holes while watering a rubber plant. This will not only hydrate the roots, but it will also flush out any salts that have accumulated from fertilization. Between waterings, allow the top few inches of soil to dry off.
How much water does a rubber plant need?
Rubber tree plants require only a small amount of water to thrive. Soak the soil with filtered water before it dries fully, letting the excess moisture to drain. In the spring and summer, rubber tree plants should be watered every 7 to 10 days, and in the fall and winter, every 14 to 21 days.
Do rubber plants need direct sunlight?
The Rubber Tree (Ficus elastica), sometimes known as the Rubber Plant, is a low-maintenance ficus found in southern Asia. They may grow up to 200 feet tall in their natural habitat, and their buttressing roots have even been trained to grow over rivers in India to build living bridges.
Because the Ficus elastica prefers moist soil, avoid planting it near a drafty window or vent, a heater, or in full sunshine. The Rubber Plant prefers bright, indirect light, however they are exceptionally tolerant of lower light areas for a ficus. However, it is often recommended that the plant be placed near a southern facing window with sheer curtains to let the greater light to seep through.
If you’re unsure about the lighting in your home or business, we’ve put together a primer on how to measure light.
What does an overwatered rubber plant look like?
Water the plant from below by soaking it in a tray for a couple of hours. It’s more uniform and less prone to overwatering in my experience.
When watering it, don’t soak it and make sure the water drains completely out of the pot. Please, no roots in the water! To do so, I hold my plant by the plastic pot and wiggle it, allowing extra water to flow through the drainage holes. After that, I keep the plant outside the decorative pot for a few hours before replacing it.
Rubber plants are a resilient species that tolerates dry soil well, thus they tend to be kept somewhat under-watered.
It’s a symptom of overwatering if the older leaves (typically the largest ones at the bottom) turn yellow or brown.
If the yellow/brown stains spread from the leaf’s interior section to the outside, it’s another indicator of overwatering.
If the plant is under-watered, all of the leaves, not just the lowest ones, will grow softer or droopy.
The tips will dry out first if the air is too dry, and the yellow/brown blotches will develop inwards.
Leaves are sturdy and firm, holding up well, and have a lovely waxy glow when the plant is well hydrated.
Should I mist a rubber plant?
Your Rubber Tree, as a tropical native, will love it if you shower its leaves to enhance humidity, especially when it gets hot in the summer. Misting the leaves on a regular basis also helps to keep mites (disruptive insects) at bay.
How long can a rubber plant go without water?
Are you going on a trip and won’t be able to bring your plants with you? Or do you have a habit of forgetting to water your plants for a few days and want to know how long they can go without water?
Plants can usually last for up to 7 days without water. However, the type and maturity level of your plants may influence how long they can go without water. Tropical houseplants may go for up to three months without water if they are fully developed, whereas succulents and cactus can go for up to two weeks.
Are rubber plants easy to care for?
Balance is the key to rubber plant care. It need exactly the proper amount of sunlight and water to thrive. You’ll have a happy, strong, and tall rubber tree if you can give it just the perfect quantity of both. If your rubber plant starts to drop its lower leaves, it’s a sign that it needs more sunlight or water. Continue reading to learn about the best conditions and ways to care for your rubber plant.
Bright, indirect light that isn’t too hot is preferred by rubber plants. Leaves that are exposed to direct sunlight may become burned. To give your rubber plant exactly the proper amount of sunlight, place it near a window with a sheer curtain. More variegated types require more light to help bring out their colors, so make sure they get plenty of it.
Water: During their summer growing season, these plants require extra water. It’s important to keep the soil moist but not soggy. To keep the leaves moist and to assist your plant receive more sunshine, wipe them down with a damp towel. If you don’t want to wipe clean every leaf, misting is another alternative. To avoid root rot, keep your rubber plant in well-draining soil at all times.
You want to keep the soil dry but not too dry during their dormant season in the winter. Allow the top few inches of soil to dry between waterings to avoid overwatering. If your rubber plant’s leaves begin to droop, it’s alerting you it needs more water.
Temperatures: Rubber plants prefer temperatures ranging from 60 to 75 degrees Fahrenheit. They can withstand temperatures as low as 50°F in the winter. A healthy temperature balance is ideal for this plant’s growth, just as it is for water and sunlight. Because of its tropical origins, it favors wet and humid air, but it may thrive in less humid conditions. Rubber plants are sensitive to temperature variations and prefer to dwell in regions where the humidity and temperature remain constant.
Toxicity: The sap of a rubber plant might irritate some people’s skin. After touching your plant, make sure to fully wash your hands, especially if you come into contact with the sap. Depending on how much of this plant is taken, it might produce mild stomach problems or more serious symptoms including diarrhea or vomiting.
Mealy bugs, mites, scales, and aphids are just a few of the pests that might infest your rubber plant. These bugs can be removed with a warm soap and water solution or an insecticidal soap if detected early.
Problems: Because rubber plants want equilibrium in all forms, it’s easy to make them unhappy if you don’t pay attention to their needs. The easiest method to avoid this is to monitor the amount of light it receives, the moisture in its soil, and the ambient temperature of the space it is in.
Rubber plants are particularly vulnerable to plant diseases caused by excessive watering. To avoid drowning your plant, let the soil dry out between waterings, as we previously recommended.

Repotting: To allow your rubber plant to grow, you should repot it. Depending on the size of your pot and how quickly your rubber plant develops, you may need to do this every few years or every year. If you want to retain your rubber plant at its current size, don’t repot it.
The simplest method of propagation is to take a short branch from a healthy rubber plant and root it in soil or water. Before planting, you should let the sap from the stem dry. Air layering is another method of propagation. To do so, cut a healthy plant open and insert a toothpick into the aperture. To keep it on the toothpick, cover it with damp moss and then wrap it in plastic wrap. Cut the branch off and replant it in different soil once you detect roots forming in the moss.
Pruning: Pruning your rubber plant will help it support itself, promote new development, and keep its size under control so it doesn’t get too big. Pruning a rubber plant is ideally done in the spring to prevent the winter, although it can be done at any time of year. Cutting the branches will cause some of the plant’s sap to leak out.
Rubber plant maintenance is simple if you keep an eye on your plant and respect its demand for balance. If you want to amaze your guests with a tall houseplant, rubber plants are definitely worth the effort.
Why are the leaves of my rubber plant falling off?
A change in the light is a common cause of a rubber plant losing its leaves. This frequently occurs when you move your rubber tree plant inside from the outside, and the change can result in the rubber tree leaves dropping completely. When the light levels shift from summer to fall, a few rubber tree leaves may fall off the plant.
When you bring the rubber tree indoors, acclimating it gently and shining a few plant lights on it can assist keep the light levels up and prevent the rubber tree from losing leaves.
Pests – Another typical cause of rubber tree plant leaves falling off is pests. Rubber tree plants, in particular, are subject to scale bug infestations, which cause the leaves to fall off unless the plant is treated.
Where should I put my rubber plant?
Bright, indirect sunshine is ideal for rubber plants. They should get morning light from an east-facing window if possible. Place your plant near a window where the light is filtered by a sheer drape or curtain.
Because the leaves of your rubber plant might burn if exposed to direct sunlight, keep it out of direct sunlight. They can also adapt to low-light environments and thrive in workplaces and other dimly lit environments. It’s a good sign that your rubber plant needs additional light if the leaves are becoming paler or the bottom leaves are dropping off.
Is rubber plant indoor or outdoor?
- Depending on the age of the plant and the time of year, the dark green, waxy leaves turn a deep crimson or purple color at the tips.
- Rubber plants thrive both indoors and out, as long as gardeners give them with the right growing circumstances. Established plants can endure cold winter nights without protection because these trees are relatively hardy.
- Rubber trees thrive in USDA Zones 9 to 11 in the United States. These trees prefer warm conditions, so you’ll have to bring them inside if you wish to cultivate them in the northern states. Indoor rubber trees continue to thrive, reaching heights of 6 to 10 feet with ease.
- To keep the plant from becoming out of hand, the indoor gardener will need to continually cutting it back. Outdoor rubber trees are in the same boat. Rubber trees placed near walls and other trees have the potential to become invasive as they grow in size. Fences will be pushed over, and the roots will rip up driveways.
