August 12, 2024
Rubber plants are stunning houseplants that can add a tropical vibe to any indoor space. Native to Southeast Asia, Indonesia, and Southern China, these fast-growing beauties are the ideal statement plants with shiny, oval-shaped leaves of deep-green to burgundy color or pink-coral variegation, depending on the variety.
Rubber plant care is easy if you provide your green companions with the right growing conditions and water them correctly. Naturally, they thrive in warm temperatures and medium humidity, hence, they are the perfect indoor plants, as you can easily control their environment inside your home.
But what about rubber plant light requirements? What is the best type of light for these exotic large houseplants to flourish and look their best? Let’s find out!
In this guide, you’ll learn all about rubber plant light needs and some helpful seasonal care tips from experts.
So, let's get started.
About Rubber Plants
Rubber plants, known scientifically as Ficus elastica, are popular tropical plants that belong to the Ficus plant genus and originate in South and Southeast Asia. They have broad, glossy, deep-green leaves or variegated foliage of various colors. Their easy-care requirements make them a favorite for both novice and experienced gardeners.
Besides their aesthetic appeal, Rubber Figs (another name for rubber plants) are known for their air-purifying properties, helping remove toxins from indoor environments. However, it's important to note that they can be mildly toxic to pets if ingested, so if you own a dog or cat, you may consider growing other pet-friendly plants.
Among the various types of rubber plants, the Ruby Rubber Plant stands out with its striking red and pink variegated leaves. The Ficus Elastica Tineke features beautiful cream, green, and pink leaves, while the Burgundy Rubber Tree boasts captivating deep, rich “burgundy” foliage that evokes visual interest.
Understanding your rubber tree plant's light requirements is a must to keep it thriving. Let's dive into the optimal lighting conditions for these vibrant plants to ensure they grow healthy and strong.
How Much Light Does a Rubber Plant Need?
A rubber plant needs at least six to eight hours of bright, indirect sunlight each day. It'll appreciate an East-facing window indoors, as it should be shielded from the harsh afternoon sunlight, which can scorch its large leaves. While certain rubber tree varieties can tolerate low-light conditions, insufficient light generally causes them to become leggy, dull, and unhealthy.
What Kind of Light Does a Rubber Tree Need?
Rubber plants thrive in bright, indirect, or filtered light to retain the vibrancy of their foliage. Too much light, especially the hot afternoon sun, can burn the plant’s delicate leaves.
Can Rubber Plants Tolerate Low Light?
Rubber plants can tolerate low light, but as said earlier, this will cause them to become leggy, lose their lower foliage, and affect the variegation on their eaves. Medium bright-light conditions best mimic their tropical habitat, assisting their optimal growth.
How to Tell If a Rubber Plant Needs More Light
If your rubber plant looks sad and unhealthy, watch out for these signs that might indicate that it needs more light:
- Slow or no growth
- Leggy appearance
- Dull or less glossy leaves
- Weakened stems
- Curling leaves
- Poor variegation
To bring such a rubber plant back to its health, move it to an East-facing window or any other bright spot with indirect sunlight. Consider adding a grow light around it to compensate for low natural light in the winter.

Yes, a rubber plant can be affected badly by too much light. Make sure to filter the incoming light using sheer curtains, preventing the harsh UV rays from harming its leaves.
Rubber Tree Light: Signs of Overexposure to Direct Sunlight
These are the typical signs of a rubber tree's overexposure to direct sunlight:
- Leaf discoloration
- Brown, crispy edges on the leaves
- Drooping or wilting leaves
- Yellowing leaves
- Scorch or burn marks on the foliage
Fixing a rubber tree plant exposed to direct sunlight is straightforward if done in due time. Move your beloved Ficus elastica near a window with sheer curtains or a bright spot with only indirect sunlight. Give your plant a quarter-turn once per month to ensure an even exposure to light. Unfortunately, you can’t do much about already damaged and scorched leaves. Just trim them off to make way for the new leaf growth.
Rubber Tree: Seasonal Care Tips
Rubber tree plants often get tricky to maintain as the season changes and the below tips will help you ensure that your botanical buddy stays on top of its health.
How to Take Care of a Rubber Plant in Summer?
Take care properly of your rubber plant in the hot, dry summer season with these expert care tips:
- Rubber plants require six to eight hours of bright, indirect sunlight each day, so protect your Rubber Ficus from the harmful summertime light in the afternoon.
- Use a well-draining and well-aerated soil mix, since it'll retain the right amount of moisture, preventing waterlogging.
- Keep your plant properly hydrated throughout the hot summer days. This also includes wiping its leaves with a damp cloth or even misting them as needed.
- Use a diluted, liquid fertilizer once a month during the growing (summer) season to replenish the soil with all essential nutrients.
Should I Put My Rubber Plant Outside in the Summer?
You can put your rubber plant outside in the summer, provided you keep it in partial shade on the porch, where it’s shielded from the UV rays. For a young rubber tree, gradually acclimate it to the outdoor environment, ensuring it doesn’t get overexposed to heat and direct sunlight.
How Do You Take Care of Rubber Plants in the Winter?
Rubber plants enter their dormant period as the winter approaches, thus requiring less attention and effort compared to the summer season.
- Place your Ficus elastica in a spot with bright indirect light; as the winter sun is lower, you may have to adjust its location in your home.
- Hold back on watering your rubber plant too frequently in the colder months. The best practice is to water every 1-2 weeks or when the topsoil feels dry. Additionally, use lukewarm ‘overnight’ water to hydrate your plant.
- Winters are generally less humid, so place your rubber plant on a pebble tray to make it comfortable. Wipe the foliage with a damp cloth to clean it and maintain hydration and the leaves’ glossiness.
- If your plant has been kept outside in the summer, bring it back indoors when the temperatures drop below 50°F to prevent stress and cold damage.
- Stop fertilizing your rubber plant in the winter, as it doesn’t need feeding during the cold months.
When Should I Bring My Rubber Plant Inside?
Bring your rubber plant inside when temperatures drop below 50°F (10°C). These plants prefer a stable indoor environment and can suffer from cold temperatures. Moving them indoors before the first frost ensures they stay healthy and thrive during the cooler months.
Rubber Plant Light Needs: FAQs
Q: Can rubber plants survive in a dark room?
A: Rubber plants can survive in a dark room for a short period but for the long term, they will show signs of poor health. Their growth will slow down, leaves will turn dull, and fall off. The stem will also weaken and start to bend. Variegated rubber tree varieties will soon lose their beautiful leaf patterns.
Q: Can a rubber plant tolerate full sun?
A: A rubber plant can't tolerate full sun, which will potentially burn its leaves. Instead, let it sit under indirect light for at least six to eight hours for good health.
Q: Do rubber plants like heat?
A: Rubber plants flourish in warm tropical environments as long as they are kept out of direct sunlight and are properly hydrated. Hot weather may affect them adversely if extra care is not provided. Ideally, they thrive in temperatures ranging from 60°F to 75°F (15°C to 24°C).
Q: How cold can Ficus elastica tolerate?
A: Ficus elastica can tolerate temperatures as low as 50°F for a few days. They are too sensitive to the cold, so it’s best to bring your plant indoors when the temperature is around 60°F to avoid damage to your green companion.
Q: Can a rubber plant survive winter?
A: Rubber plants don't go fully dormant in winter, but their growth typically slows down, due to lower light levels and cooler temperatures. During this period, they require less water and should be kept from cold drafts. Ensuring they receive adequate indirect light can help them maintain their health through the winter months.
Conclusion
Understanding and providing the right light conditions is essential for a thriving rubber plant. These plants flourish in bright, indirect light and should be protected from direct sunlight to avoid leaf damage.
Some companion plants with similar light requirements that you can grow with your Ficus elastica are Snake Plants, the popular ZZ Plant, and everyone’s favorite Golden Pothos. These low-maintenance plants also thrive in indirect light, making them perfect buddies for your rubber plant. With proper care and the right lighting, your indoor garden will flourish beautifully.
