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.
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.
How often should I mist my rubber plant?
Keep the soil moist during their growing season, which is usually in the summer in most areas. Once a week, water the plant and lightly spritz or clean the leaves with a damp cloth. It’s fine if the soil becomes dry between waterings throughout the winter, when rubber plants are dormant. During this time, water them every 2 to 3 weeks. Overwatering causes leaves to turn brown or yellow, while underwatering causes leaves to droop.
Why is my rubber plant dropping leaves?
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.
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.
Why is my rubber plant leaves turning yellow?
Inadequate soil moisturein particular, overwateringis the most prevalent cause of yellowing leaves in Rubber Trees. When the top 2-3 inches of soil are dry, water your Rubber Tree. The soil should be moist but not wet. Allow your plant to dry out a little more between waterings in the winter.
How do you encourage the growth of a rubber plant?
Freshening the soil with a composted mixture, watering and feeding, and providing sufficient light are all other strategies to encourage rubber tree branching, or to employ in conjunction with the cuts. Upgrade Soil: If your rubber tree is enormous, you may not want to take it out of the pot entirely.
What temperature do rubber plants like?
Rubber plants thrive in strong light, but they can also thrive in dim light. They thrive in the morning light coming in via an east window. They thrive in rooms that are warm to average in temperature. The optimal temperatures are 60 to 65 degrees Fahrenheit at night and 75 to 80 degrees Fahrenheit during the day. Avoid temperatures below 55 degrees Fahrenheit, temperature dips, and cold drafts.
Thoroughly water rubber plants, but allow the soil to dry somewhat between waterings. Make certain the pot has adequate drainage holes. After watering the plant, remove the surplus water from the saucer where the pot is sitting. A well-drained houseplant mix should be used as the soil mix. Rubber plants like moist environments, but can endure the dry air found in most homes.
During vigorous development in the spring and summer, fertilize with a water-soluble houseplant fertilizer on a regular basis. Every two weeks, you should do this. Fertilize your plants less frequently if they are in lesser light.
Indoors, rubber plants can grow tall and lanky. You can stake them or prune them in the spring to revitalize them. New plants can be propagated through stem or tip cuttings, or by air layering. If necessary, repot in late winter or early spring.
When the leaves become dusty, wash them with water to maintain them appealing and your plant healthy.
Why do rubber tree leaves curl?
Rubber plants are vulnerable to gas fumes, insecticides, and other pollutants, even if their toxicity levels are undetectable to people. Leaf curl on rubber plants can also be caused by pollutants in garden soil or potting soil. It’s possible that repotting in new soil is required.
Leaf curl can be caused by both over- and under-watering of rubber plants. Allow the soil to dry somewhat between waterings, then water deeply until water leaks through the drainage hole with room temperature water. Wait a day or two before watering if the soil feels moist. During the fall and winter, you’ll need even less water, but don’t let the soil dry out completely.
Low humidity – The curling of indoor rubber tree plant leaves could be due to dry indoor air. The humidity level around the plant can be increased with the use of a humidity tray. To build a humidity tray, fill a shallow tray or dish with gravel or pebbles, then place the pot on top of the pebbles. Fill the tray with water to keep the pebbles moist, but don’t let the water contact the bottom of the pot, since moisture can leak up the drainage hole and damage the plant.
