Rubber Plant Care

The rubber plant, also known as Ficus elastica, is a lush, tropical tree that has become a popular indoor houseplant. It is favored for its robust, glossy leaves and its ability to purify the air. Proper care is essential for this plant to thrive indoors. This article will guide you through the necessary steps to ensure your rubber plant remains healthy and continues to grow, enhancing your living space with its natural beauty.

Scientific Classification

When you look at a rubber plant, it belongs to a large family of plants. But like people have names, so do plants, and scientists have a special way of sorting them. Here’s where a rubber plant fits in the plant world:

  • Kingdom: Plantae
  • Division: Magnoliophyta
  • Class: Magnoliopsida
  • Order: Rosales
  • Family: Moraceae
  • Genus: Ficus
  • Species: Ficus elastica


Rubber plants need the right amount of light to grow well. They like bright, indirect sunlight. This means you should place them near a window, but not in the direct path of the sun’s rays. Too much direct sunlight can burn the leaves, causing them to turn brown and crispy. On the other hand, if the plant doesn’t get enough light, its leaves will become too dark and its growth will slow down. Ideally, you want to find a spot that gets plenty of light during the day, but where the sun isn’t hitting the plant directly. That’s how you can make sure your rubber plant has the light it needs to be happy and healthy.


When you take care of a rubber plant, water is like a balanced meal. Just like you don’t eat too much or too little, your rubber plant needs the right amount of water. The plant’s soil should be moist, but it shouldn’t be soaking wet. To check if it’s time to water, feel the top inch of soil with your finger. If the soil is dry, it’s a good time to water. If it’s still damp, wait a couple of days and check again. Over-watering can be bad news for the roots. It can cause root rot, which is like a plant’s cold. So remember to water your rubber plant when needed, but don’t overdo it. Just enough water keeps the plant happy and healthy.


Soil is like a home for your rubber plant’s roots. It needs to be just right so the plant can grow well. For your rubber plant, you should use soil that doesn’t hold too much water. This means it should drain well. The best kind of soil to use is a mix made for indoor plants or a mix that has peat, pine bark, and perlite. These ingredients help water flow through the soil. Your rubber plant will not like soil that is always wet. Wet soil can cause the roots to rot, which is bad for the plant. Therefore, choosing the right soil is key to keeping your rubber plant healthy.


Rubber plants like it warm. They thrive when the temperature stays between 60°F and 75°F. This range is close to what we often have in our homes. However, these plants get stressed if the temperature drops below 50°F. Keep your rubber plant away from drafts and cold windows in the winter. Also, make sure it’s not too close to air conditioners or heaters. Temperature changes can shock the plant, leading to leaf drop. Therefore, consistency is key for a happy rubber plant. During the summer, protect your plant from too much direct sunlight as it can get too hot. If you take care of your rubber plant with the right temperature, it will grow well.


Humidity is the amount of water vapor in the air. Think of it as the air’s wetness. Your rubber plant needs a certain level of humidity to be happy. It loves the air to be a bit moist, like a tropical forest. If the air in your room is too dry, your plant might get sad. Its leaves can start to look droopy or get brown edges. You can raise the humidity around your rubber plant by misting it with water, placing it on a wet pebble tray, or using a humidifier. These help create an environment like the plant’s natural home. You’re aiming for a humidity level that makes the air feel just slightly damp, not wet or soggy. This level of humidity keeps your rubber plant looking fresh and healthy.


Fertilizer is like a vitamin for plants. It gives your rubber plant essential nutrients that may not always be present in the soil. Think of it as food that helps your plant grow strong and healthy. You don’t need to use it all the time. Once every month during the growing season, which is spring and summer, is enough. But remember, in the fall and winter, your rubber plant doesn’t grow much and doesn’t need extra food. So, you should stop fertilizing during these cooler months. When you do fertilize, pick a liquid fertilizer made for indoor plants. Follow the directions on the label closely—it will tell you how much to use. If you use too much, it can harm your plant, just like eating too much can make you feel sick.

Size & Growth Rate

Rubber plants are known for their impressive growth. When given the right care, they can grow very tall. Inside a house, they can reach up to 6-10 feet. Some may even grow taller with enough time and space. In their natural habitat, they can grow over 100 feet tall! However, indoors, their growth rate slows down. You’ll notice your rubber plant growing more during the spring and summer. This is their active growing season. During the colder months, they grow slower or not at all. This is normal, so don’t worry. To help your rubber plant grow well, provide it with proper light, water, and nutrients. With these, it will grow strong and healthy. Remember, growth can also depend on the plant’s individual conditions and care.

Common Issues

When you take care of a rubber plant, you might face some problems. These plants can get sick or look less healthy if not treated right. For example, the leaves might turn yellow or drop off if something is wrong. Often, this happens when you give it too much water or not enough light. Pests such as spider mites or mealybugs can also attack your plant. These tiny bugs feed on the sap of the rubber plant, weakening it. The leaves can become sticky or covered with a black sooty mold. Plus, if the air is too dry, the tips of the leaves might turn brown. However, knowing the right ways to care for the plant can help prevent these issues. If you spot them early and take action, you can usually save your rubber plant.


The term “toxicity” refers to how poisonous a substance is. In the context of a Rubber Plant, it means that the plant can be harmful if you or your pets eat its leaves. The sap inside the leaves and stems contains chemicals that can cause skin irritation. They can also upset your stomach if you swallow them. Cats and dogs are curious by nature and might chew on the leaves, so it’s best to keep your Rubber Plant out of their reach. If you touch the sap, you should wash your hands right away. Remember, just because a plant is toxic, it doesn’t mean it can’t be a happy part of your home. You just have to be careful about how you handle it.

Pro Tips

Taking care of a rubber plant might seem tricky, but you can do it with some easy tips. Here’s what you should keep in mind:

  • Placement is key: Find a spot with bright, indirect light where your plant can bask comfortably.
  • Don’t overwater: Wait until the topsoil feels dry before giving your plant a drink to prevent root rot.
  • Stay consistent: Keep your rubber plant in an environment with stable temperature and humidity.
  • Feed it right: Give your plant a balanced liquid fertilizer during its growing season for best results.
  • Wipe the leaves: Clean the leaves with a damp cloth to keep them shiny and healthy, allowing them to breathe.
  • Watch for pests: Inspect your plant regularly for signs of pests or diseases and address them quickly.
  • Prune when necessary: Trim any excessive growth to maintain your rubber plant’s shape and encourage healthy growth.
