One of the most popular indoor plants is the Rubber Plant. It’s a very adaptable plant, but it can struggle to grow at times.
Many people question why the rubber plant isn’t growing. Is it normal for them to grow slowly, or do they have a problem? Let’s see what we can find out!
Stunted growth of the rubber plant is caused by a lack of proper lighting, insufficient watering, and the use of the incorrect soil type. To watch a rubber plant develop quickly, place it in a bright position with well-draining soil and plenty of water. During the winter, rubber plants can go dormant.
Aside from those frequent concerns, there could be a variety of causes for the rubber plant’s growth to stagnate. The following are the reasons:
Yes, the fact that your rubber plant isn’t growing is a cause for concern, but you can always lessen your tension by determining the main cause and taking immediate action.
When you get your plant home, you should still be able to figure out what it needs, and we’re here to help. For more information, continue reading.
How do you encourage rubber plants to grow?
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.
How can I get it to branch out from only one stalk?
To get a plant that branches out, you have two possibilities. To begin, you can simply buy it that way (instant gratification). Alternatively, if you have a single stalked rubber plant, cut the top off just above one of the leaves.
At the very least, you should see a couple of fresh stems sprouting soon.
If you have a woody rubber plant, you should consider air layering it.
You may propagate your plant at the same time this manner!
Finally, there’s a technique known as notching, in which you don’t actually cut anything off the plant.
Simply making selective partial cuts on a branch just above a node might cause side branches to emerge.
Why is my rubber plant not growing?
In the vast majority of cases, the answer is simple: light. If your rubber plant isn’t already in front of a window, I urge you to do so immediately and wait. Patience is required.
It spends the majority of its time in a dark corner.
When it comes to plant growth, there are no shortcuts.
The most vital component is light, and your rubber plant will not live and grow effectively if it is placed in a dark area of your home.
Why do my leaves fall off, still green, until the entire branch is defoliated?
There could be a number of reasons for this. One possibility is a rapid drop in light. Have you recently purchased your plant from a nursery and taken it home?
Rubber plants frequently show their displeasure by shedding some leaves until they become accustomed to their new surroundings.
However, because light is so important, your rubber plant must be placed directly in front of a window.
Why are the new leaves smaller than the older ones?
This indicates to me that the growing conditions were less favorable when your rubber plant produced smaller leaves. This is most likely due to a lack of light. Change the location of your plant to one that receives more light (you guessed it…in front of a window).
How do I keep my Ruby leaves pink?
If your Ficus elastica ‘Ruby’ leaves aren’t as pink as they should be, you’ll need to increase the amount of light. To get the greatest effects, place your Ruby directly in front of a window. This will bring out the best color in the leaves.
However, because variegated types are more vulnerable to direct sunlight than non-variegated varieties, too much direct sunlight can scorch the leaves.
I should point out that burning is usually caused by quickly raising the brightness.
Variegated rubber plants can withstand a lot of sun, and I’ve seen them thrive in direct sunlight.
As a result, whenever you move a plant into much brighter light/sun, take it slowly to avoid scorching.
In most circumstances, growing these plants indoors, Eastern exposure windows, or even Western or Southern windows, should suffice.
Outside, rubber plants thrive in full daylight, so there’s no reason you can’t offer your plant as much sun as it needs indoors, where the light intensity is much lower.
Why are some of my leaves folding like a taco?
It’s most likely a problem with irrigation. Take a look at the plant in the picture below. This was a buddy who inquired about my situation. She was measuring moisture in her plant with a moisture meter and hadn’t watered it in months. Months!
The moisture meter said she was fine, but the soil remained bone dry for a long time after a few months, and the ensuing leaves were crumpled, folded, and taco-like.
Why do my leaves get discolored, then turned yellowish, and then turn brown and fall off?
Improper irrigation is usually the cause of this. Either the soil has been left too dry for an extended period of time (“underwatering”) or it has been kept too moist for an extended period of time (“overwatering”).
Check the soil with your fingers as soon as you notice yellow leaves, and lift the pot if possible to check the weight.
Is the soil fully dry, and has it been dry for an extended period of time?
Is the pot light in weight?
Is it dripping wet, and has it been that way for some time? Yellowing leaves can be caused by either of these causes.
When it comes to watering, you must strike a balance.
Reread the section on watering earlier in this blog post and make an effort to follow all of the other cultural practices, such as light, fertilizing, and so on.
It’s also possible that your rubber plant is severely pot bound and requires repotting into a larger container.
Before you repot any houseplant, make sure you read these important repotting tips.
Why are there brown spots on the leaves?
It’s possible that a bacterial or fungal infection is to blame. Bacterial infections usually have a yellowish halo surrounding the brown area, whereas fungal infections usually don’t.
Plants can become infected if they are kept excessively damp, especially in places with little light and poor air circulation.
Why do my leaves have tiny white spots?
There’s no need to be concerned if you notice little white specks on the outside edge of your rubber plant leaves.
Lithocysts are the microscopic white spots that make up a lithocyst.
Lithocysts are swollen cells in rubber plants that contain calcium carbonate crystals.
I’m not sure what they’re there for, but it’s perfectly natural!
Why are my leaves curling up and drooping?
This is almost certainly due to a lack of water. The leaves can droop and curl if the soil is kept too dry or too damp.
Feel the soil of your plant as soon as you detect your leaves curling and/or drooping.
Is it extremely dry?
Is it raining?
This will inform you of the situation.
If you have neglected your plant and it has become too dry, you must water it more frequently.
There could be a number of reasons for your soil remaining wet for an extended period of time:
- Your plant will stay wet for longer if it is in low light. Place your plant near a window.
- Has your plant been sitting in a saucer full of water for a long time?
- Rubber plants could be in serious trouble as a result of this.
- Excess water should always be discarded.
- Is your plant in a pot that doesn’t have a drainage hole?
- This is a complete no-no.
- Transplant your rubber plant into a pot with a drainage hole as soon as possible.
- Ficus are extremely sensitive to being submerged in water.
- Maybe everything else is in order, but your plant is in a cool/cold environment.
- It should be moved to a warmer place.
- These plants despise chilly temperatures and are irritated by drafts.
Lower humidity can also contribute to curling. I wouldn’t be concerned if the curling is little and the plant appears to be healthy otherwise.
Many parts of the world experience harsh winters, but you can make your home more humid by using a humidifier. Although proper watering is far more important, increasing humidity is also beneficial to your plants.
Why are the new leaves deformed?
This can be caused by a multitude of factors, including pests, nutrient deficiencies, and inconsistent and/or incorrect maintenance, as with many other aspects of houseplant care. All of these stresses on the plant can result in distorted leaves.
Check for pests on your plant.
Is there anything crawling or flying in the area? If everything appears to be in order, consider your care. Have you been neglecting your houseplant? Maybe let it dry out for a long time while the new leaves sprouted? Perhaps it’s also in a dimly lit area?
Deformed young leaves can develop from inconsistent care.
Your plant will reward you and new growth will seem normal again if you resume constant watering, light levels, and so on.
Nutrient deficiencies are less prevalent, but if you use a good, complete fertilizer like Dyna-Gro Grow (available on Amazon), you shouldn’t have any problems.
And, regardless, you should fertilize!
Why are there brown edges on the variegated rubber plants like tineke and ruby?
This can be caused by inconsistency in watering or sun scorch from not adequately acclimating your plant to brighter light. Rubber plants with variegated leaves can withstand a lot of direct sunlight. If your plant has previously been in a darker location, gradually acclimate it to any direct sunlight to avoid any problems.
If your plant is growing in extremely warm or hot settings and is exposed to direct sunlight without acclimating, the leaves may be scorched.
Variegated plants are particularly vulnerable.
Brown spots on your variegated leaves are usually caused by insufficient watering or general soil moisture extremes.
This can be caused by both “underwatering” and “overwatering.”
As soon as the top one or two inches of the pot (depending on the size of the pot) are dry, give your plant a thorough watering.
Remove any surplus water.
How can I get hard water stains to come off the leaves?
Those obstinate hard water stains on your rubber plant leaves can be safely and quickly removed. 1 teaspoon white vinegar in a gallon of warm water is all it takes.
Wipe the leaves with hard water stains gently.
The vinegar aids in the dissolution of those pesky mineral deposits left by hard tap water.
Why did my rubber plant drop leaves when I first brought it home?
Some plants may drop leaves when you first bring them home because they are in shock from being in a bright, humid greenhouse to normal indoor settings.
To make the transition a little easier, set your plant directly in front of a window (at all times, but especially when you first bring a plant home).
Why is my plant staying bushy but not growing tall?
If your rubber plant remains bushy and does not appear to be expanding, it most likely requires additional light. Give your plant some time if you’ve just transferred it into brighter settings. Watering, lighting, and fertilizing properly will eventually get you there, but be patient.

Rubber plants, as you’ve discovered, can cause a slew of issues.
They are, however, simple to grow if you follow my cultural norms for light, hydration, and soil.
It’s one of my simplest and least finicky plants.
Why is my rubber plant growing so slowly?
If dormancy has been ruled out and you know your Rubber Tree should be growing vigorously during its growing season, the next most likely cause is a lack of light.
Rubber tree growth is slowed or interrupted due to a variety of environmental factors, the most common of which is inadequate light. Rubber Trees, like many other Ficus varieties, can be fickle about how much light they receive, and even a few inches closer or farther from a window can make a big difference.
Rubber trees are endemic to Southeast Asian rainforests, where they have evolved to grow tall quickly in order to collect as much dappled, indirect sunlight as possible as it filters down through the dense forest canopy. So, while our domesticated versions don’t grow as tall as their wild counterparts, they still have the same rapid growth tendency and require a lot of light.
If you think your Rubber Tree isn’t getting enough light, try to find a location in your house where it can be as close to an east- or south-facing window as possible without being in direct sunlight (which is too hot and can scorch the leaves). These plants prefer bright, indirect light, so they thrive in the reflected light that bounces off the room’s surfaces. Allow the plant to settle in its new location for a few weeks before checking to see if growth has resumed.
While Rubber Trees can tolerate and thrive in a wide range of light levels, with a little trial and error, you’ll be able to figure out which areas of your home (and thus what light levels) are best for keeping your Rubber Tree happy and growing.
Why are my rubber plant leaves small?
There are a few common difficulties with rubber plants, despite how simple they are to care for.
You can figure out what’s wrong and how to fix your plant with a little digging (no pun intended).
Leave a comment below if you have any additional questions about rubber plant maintenance or want to share your plant’s tale!
Leaves Dropping
The leaves usually fall off as a result of overwatering or too much fertilizer.
Rubber plants dislike being moved and will shed leaves in response to unexpected changes in light or temperature.
Leaves Drooping
If you find your rubber plant’s leaves are drooping, it’s nearly often due to a lack of water.
Your rubber plant is underwatered if it becomes limp and the soil is dry. Give it a soak and it’ll brighten up in no time.
When the leaves begin to droop while the soil remains moist, the droopiness is due to overwatering. Water will be used less frequently in the future.
Small leaves
It’s usually due to a lack of light that your rubber plant’s leaves remain little.
Another reason could be that your plant is still young and has smaller leaves to begin with. The leaves will grow in size as the plant matures.
Toxicity to Pets
You may have guessed it based on the sap inside the rubber plant, but rubber plants are harmful to pets such as cats and dogs.
If your pet ingests portions of this plant, they may vomit and lose coordination. Keep your rubber plant away from your dogs to stay safe.
It is quite rare for pets to die as a result of eating plants. They can, however, become ill. It’s usually a good idea to do some research and figure out what kind of plant you’re bringing home.
How do I make my rubber plant bushier?
Take a step back and take a look at your rubber plant. Consider its location and current growth when deciding how you want it to look.
If your rubber plant is on a table or shelf where there isn’t much room for it to develop, it’s usually best kept as a short, circular shrub.
Pruning lateral branches will encourage new growth to fill in the plant’s centre portion, so pick a size you can work with and then let it fill in on its own.
Step 2: Remove any branches which seem out of place.
Begin by trimming back any lower branches that appear to be growing straight out horizontally or that are interfering with the plant’s desired shape.
Some branches will grow in unusual directions, twisted, or at a significantly faster rate than others. To keep the plant looking tidy and appealing, remove these.
To keep the plant from looking overly dense, trim some branches and leaves from the middle section, but this is a matter of personal opinion.
Step 3: Cut to your desired height.
Trim the top set of leaves before the node after your rubber plant has reached the appropriate height. By cutting before the node rather than after it, you’re essentially leaving a stump. The plant will no longer be able to send out any more vertical chutes as a result of this.
Trim the top of the rubber plant when it reaches a maximum height of four feet for a more compact shrub-like shape. Instead of growing tall and narrow, this will encourage the plant to grow more horizontally and produce a more rounded form.
Step 4: Encourage leaf coverage by pruning often.
As previously said, caring for a rubber plant as a bushy shrub needs a little more effort than caring for it as a larger tree-like houseplant. Pruning is required to maintain a bushy rubber plant.
When a cut is made after a node, one or two additional branches will begin to grow from the location where the cut was made. Cut them back as well after the plant has recovered from the previous pruning and sent out some new chutes.
You may manage how thick and bushy the plant develops by trimming the new lateral growth on a regular basis.
Step 5: Propagate new cuttings back into the pot.
Propagating rubber plant cuttings is simple and straightforward. You can achieve a more shrub-like appearance by planting these cuttings back into the pot of your rubber plant, which will help to fill in the lower sections of the plant.
After pruning, cut branches can be immediately transplanted back into the same pot as the original plant, or they can be rooted first in a glass of water.
Where should I place a rubber plant in my house?
Place your rubber tree in a light-filled, south-facing window. Every day, it needs a lot of bright indirect light. This indoor plant will get leggy in low-light situations as it searches for sunlight.
Is my rubber plant dead?
Rubber plants despise sitting in water, therefore this will destroy your plant faster than underwatering. Overwatering your plant can cause root rot, which causes the plant to become unstable and unable to obtain vital nutrients through its root system. Root rot is one of the most common causes of houseplant death, and it must be treated right away.
Overwatering is indicated by the yellowing or browning of the lower leaves of your rubber plant. Check the moisture level in the soil and adjust the irrigation accordingly. If the potting soil becomes waterlogged, refill it right away (rather than waiting for it to dry out naturally) so that the roots can begin to recuperate.
How often should I water rubber plant?
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 long does it take for a rubber plant to grow new leaf?
Mine used to produce a new leaf every 3-4 weeks when it was in bright sunlight in a southern window, but now that it is in a west facing window with lower temperatures, it hasn’t produced a new leaf in over 8 weeks. That makes me happy because the summer growth is nice and compact and healthy. On that branch, I don’t want an etiolated section.
My Ficus elastica ‘Tineke,’ which rests on the same windowsill, surprised me by unfurling a leaf the other day.
How do I make my rubber tree leaves bigger?
Rubber plants that lose their leaves might become leggy, which means they have no leaves on the lowest half of the plant. Rubber plants only sprout leaves at the top of their stalks, not at the bottom. As a result, there is no way to make a plant leaner.
Replant lesser stalks in the planter with the larger ones to make your Rubber Plant appear fuller. This will make the plant look bushier by filling in the lowest naked space.
