Rubber Plant Care

Ancient Mesoamericans used rubber trees as a key ingredient in the creation of bouncy balls. In parts of India, people use their roots to create ‘living bridges’ across smaller rivers, while they’re best known these days for being attractive interior plants whose smooth finish enhances any room, carrying with it health benefits too!

Rob the rubber plant has a variety of shades in his leaves and is variegated; whereas, his brother Robin only has one shade of leaf. Remi and Melika are made for homes with low ceilings that don’t want trees blocking out light from windows. And, Reuben’s pink-hued leaves will stand out from the rest. 

Propagation of a Rubber Tree Plant

It’s easy to propagate indoor rubber trees once you know how to care for a rubber tree plant. A few different methods exist when trying to make new cuttings of your own; one is that you take a healthy branch from one of your plants, place it in some good potting soil or water, and wait for it to grow roots.

Another method is called air layering – which entails making a small incision at the base of one of your healthy trees (making sure not to harm any part of the trunk), placing an object inside (like a toothpick) with damp moss wrapped tightly around the wound. Wait until there are signs roots are forming before cutting off the stem and planting it accordingly. 

Rubber Plant Characteristics

Rubber plants originate from India, but can now be found all over the world. They are thick-leafed, dark green, and can grow up to 6 meters in height – though it is unknown how high they can grow because they’ve never been experimented on outside of the jungle before.

In their natural environment, the plant’s trunk is an average of 6 feet 7 inches. However, when grown inside it becomes an average houseplant at just over 3ft tall or a large tree reaching heights no taller than 8ft. You’re best off buying them while they’re still young so they can adjust to being inside – anything less and they’ll never survive! 

Selecting Soil for Rubber Tree Plants

Rubber plants need well-draining soil to prevent root rot. The soil needs to drain completely after each watering, but they also enjoy moist (but not soggy) soil that stays moist but doesn’t stay wet for too long. A recommended mix of 1 part peat, 1 part pine bark, and 1 part sand will keep the roots happy.

Propagating Rubber Plants

It’s easy to propagate rubber plants. Cuttings should be at least 6 inches long, including 4 leaf nodes, and dipped in the rooting medium after the sap has dried. After removing the bottom leaves from the cutting (leaving 2-3), plant it about 1 inch deep in an all-purpose potting soil mix of peat moss and perlite–be sure to keep it moist!

If you want to encourage root growth, plant the stem in soil and place its container on a heating pad. When propagating houseplants, it’s best to do so in the early spring through late summer when they are in their growing season.

Safety Considerations

The milky white latex that rubber plants produce can cause irritation for people, so it’s important to wash your hands right after you touch one. They are also dangerous if eaten, so make sure they are out of reach from pets and small children at all times.

Potential Pests and Diseases

Rubber plants are relatively pest-resistant and won’t typically succumb to an infestation, but they’re still sensitive to bugs. Aphids, spider mites, thrips, and scale are a few of the most common culprits. You can use a natural or chemical insecticide to ward off these pests for good if you spot them on your rubber plant. These pests can also be eliminated from your houseplant with neem oil and other horticultural oils.

Overwatering might cause root rot in rubber plants. Make sure you let the soil dry completely before watering again if you notice the leaves drooping or yellowing.

Are rubber plants easy to look after?

These plants are tough, hardy, and don’t need much attention to keep them happy. You just need to keep their soil slightly moist while giving them enough sunlight every day. If you’re keeping them warm enough, they’ll stay comfortable as well!

Just make sure you keep rubber plants out of the way from small hands and inquisitive paws, as contact with the latex found in these plants could cause some skin irritations or even poisoning if eaten.

How often should I water my rubber plant?

As with most houseplants, there are some simple clues to tell whether your plant is thirsty. If your finger comes out mostly clean and dry after digging about 3 inches into the soil, it’s time to water! Wait another couple of days if there’s still plenty of moisture left on your fingertip. During periods of excessive heat (spring/summer), you’ll want to water more frequently because plants need more water in warmer temperatures.

Make sure you water your plants adequately so that each individual root gets watered thoroughly. Make sure to drain your plant before putting it back in the decorative pot to prevent water from sitting at the bottom, which can cause root rot. If your rubber tree’s leaves start going yellow or brown, or if they’re falling off entirely; then this could be a sign of overwatering.

How much light and humidity does my rubber plant need?

Their leaves are super hydrated, so they’re totally cool with normal room humidity levels. If you’re wondering how much light they need, the rule of thumb is to keep them in bright rooms a few feet away from windows that get direct sunlight; or just find the most comfortable temperature for yourself – it varies depending on who you ask.

Repotting rubber plants

Rubber plants grow rapidly, so keep an eye on them during the summer if their roots poke out of the pot. It’s time to report if they are. Thus, their roots have enough room to spread out, absorb nutrients, and grow. Click here for more information on repotting.

Show your rubber plant some extra love

This will need to be diluted with an equal part of water because they are not heavy feeders. Rubber plants also like their leaves to stay fresh and clean, so feel free to wipe down their leaves using a damp cloth to keep them dust-free and spritz them with water every few days!

How big does a Rubber Tree get?

Outdoors, this plant can grow up to around 30 ft. (10 meters) tall and about 10 ft. (3.2 meters) wide over the years; inside, it will only grow up to 6-10 ft. or 2-3 meters high at best, given the right conditions.

Are Rubber Trees safe for pets?

This plant isn’t pet-friendly; because of its milky sap, it has been known to cause feline toxicity, canine toxicity, and human toxicity when ingested. The best practice is to keep this type of houseplant away from small children and pets at all times.

Rubber Plant Care Tips

The key to caring for your rubber plant is finding the perfect balance of water and light. When you provide it with just enough of each, you’ll have a happy, thriving, and healthy rubber tree. If you notice that your rubber plant’s lower leaves are drooping, it means it needs more sunlight or water – read on to find out what type of conditions are ideal for these trees.

SunLight

Direct sunlight can burn the leaves; so you might want to place them next to a window with a sheer curtain that helps diffuse the light coming through. Variegated types will need extra lighting to bring out their colorful stripes so make sure they’re getting enough brighter light in order for this effect to happen effectively.

Water

You can also wipe down each leaf with a damp cloth and misting regularly will increase the absorption of sunlight too. Finally, do your best to maintain good drainage at all times to avoid root rot, which could turn out fatal for your plant.

Let the top few inches of the soil just about completely dry out before watering again to make sure you’re not over-watering – otherwise, your rubber plant will start to show signs of being overwatered (such as drooping leaves).

Temperatures

The ideal temperature range for rubber plants is 60°F to 75°F. They can survive in temperatures as low as 50°F during the winter. In the same way that plants need water and sunlight, a balance of temperatures is ideal for their growth. It prefers moist and humid air due to its origins in a tropical climate, but it can tolerate less-humid climates too (although it doesn’t like them). This plant is sensitive to changes in temperature and moisture levels, so it lives best when exposed to stable conditions.

Toxicity

If you are sensitive to the sap from rubber plants, be sure to wash your hands thoroughly after handling them, especially if you come into contact with the sap. Consuming this plant may cause mild stomach problems such as stomachaches or constipation; but if consumed in large quantities, it may also cause more severe symptoms like diarrhea or vomiting.

Pruning

Maintaining the appearance of your rubber plant and encouraging new growth is important, as is controlling its size to prevent it from growing too big. A rubber plant can be pruned at any time of the year, but it is best to prune it in the spring to avoid the winter months. Keep in mind though – when you cut branches from the stem – that some sap may be released as well.
