While rubber plants thrive in bright, indirect light (such as that provided by south- or west-facing windows), they can also thrive in lower light, making them ideal office plants. Aside from the fact that bright, direct light might sunburn them, they aren’t fussy about light. Rubber plants are tropical plants that don’t appreciate being struck with chilly blasts of air from doors or drafty windows, and if they are, they may drop some leaves.
Rubber plants can be grown outside in both sunny and shaded regions if you live in zones 10 through 12. Rubber trees grown in rich, well-draining soil can grow to be quite large (20 to 30 feet tall), so make sure you place them where they can spread out a bitor cut them.
Can a rubber tree survive outside in the winter?
Your rubber tree will survive most winters if you live in USDA Plant Hardiness Zones 9-11. If the temperature drops below 60 degrees for an extended period of time, you may need to take precautions. Plant your rubber tree in a protected location. Wind and cold can be deflected by a few larger trees, the side of the house, or even the patio.
If you have an outdoor potted rubber tree, consider bringing it inside during the winter months. Then it will have a better chance of surviving whatever winter throws at it. Remember, this is a tropical plant, therefore it prefers warm weather.
When can I put my rubber plant outside?
Rubber plants can be grown outside in zones 10 and 11 in the United States. (Zone 9 is also an option if you can protect them throughout the winter.) Otherwise, store them in a jar to bring inside once the temperature drops below 30 degrees in the winter. Plant them in the shade or in dappled sunlight, where they can reach a height of 100 feet. They make excellent space dividers and privacy screening on patios and decks due to their size.
What temperature can a rubber plant withstand?
Temperature: Rubber plants thrive in warm temperatures of 60 to 75 degrees Fahrenheit, although they can withstand temperatures as low as 50 degrees in the winter. If the air is too dry, you may want to water the leaves of your rubber plant to keep them moist.
Light:
According to ProFlowers, rubber plants want bright light to thrive, but don’t put them in the brightest spot you have just yettoo much hot, direct sunshine might scorch your plant’s leaves. Your best bet is to place your rubber plant in a location that receives plenty of sunlight but is shaded by a sheer curtain. Colorful or variegated rubber trees will require a little additional light to bring out the colors in the leaves, but according to Bloomscape, rubber plants’ leaves will actually grow larger in lower light conditions (which they can tolerate, don’t worry!) but fade to a lighter shade of green.
Water:
In the summer, keep the soil of your rubber plant wet but not waterlogged. You’ll want to water it less in the winter, when it’s dormant. Allow the top two inches of soil to dry between waterings; simply feel the soil to see if it’s dry. What’s the good news? Rubber plants are very vocal about their demands, so if the leaves begin to droop, you’ll know your plant needs more water.
Temperature & Humidity:
Because rubber trees are tropical, they thrive in hotter, more humid conditions and struggle in colder, drier regions. They should be kept between 60 and 78 degrees Fahrenheit, and any large cold breezes or sudden temperature decreases should be avoided. They also require spraying on a frequent basis to maintain their humidity.
Do rubber plants come back after a freeze?
A rubber tree can withstand frost as long as it isn’t too severe or prolonged. If the freeze was not too severe and only a tiny portion of the stem and a few leaves were damaged, the plant is usually not killed. Most plants can usually recover from this with a little TLC.
How do you care for an outdoor rubber plant?
Rubber plants can be grown in full sun or light shade outdoors. Because they like heat and humidity, it’s a good idea to mulch the roots with a 2-inch layer to keep the soil moist for longer. When the top inch of soil on your trees becomes dry, water them. The optimum time to water is in the morning. Any water splashed on the leaves will have enough time to dry before the evening. Diseases like downy mildew thrive if water left on the leaves overnight. During the winter, when the trees are dormant, you can cut back on watering. Fertilize every three months during the growing season using a balanced fertilizer like 10-10-10. To avoid illness or insect infestation, always remove any dead leaves or branches as soon as possible.
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 just the right amount of sunlight, place it near a window with a sheer curtain. More variegated varieties 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 small 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 growth, and keep its size under control so it doesn’t get too big. Pruning a rubber plant is best done in the spring to avoid the winter, but 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.
Where do 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.
Can rubber trees grow anywhere?
Ficus elastica is native to South and Southeast Asia, although it has naturalized in a variety of locations around the world. The Rubber Tree may reach heights of 90-150 feet in its natural habitat, with occasional peaks of 200 feet! To maintain the height and weight of the tall trees, they generate a large number of shallow roots around the base of the trunk (known as buttressing roots).
Although cultivated Rubber Tree Plant varieties will never reach these heights, their native relatives should give you an idea of how quickly your indoor Rubber Tree might grow.
Are rubber tree plants Hardy?
Rubber trees are hardy plants that don’t attract a lot of pests or illnesses, whether they’re indoors or out. If you’re planting in the garden, keep an eye out for mealybug and aphid infestations in the early summer.
Scale can also be a concern, causing the rubber tree’s leaves to wilt or droop. Remove the bugs with your fingers if you catch the infestation early. If the infestation is severe, use an organic insecticide like neem oil to spray your tree.
Allow the soil to dry out between waterings to avoid root rot in your rubber tree, but keep it moist beneath the surface. Spider mites lay their eggs in dry soil, speeding up the infection.
