Rubber plants aren’t huge eaters when it comes to fertilizer, but frequent treatments throughout the growth season help the plant produce those enormous, glossy leaves while also keeping it healthy.
You should fertilize your Rubber Plant just when it is actively growing, which is usually from spring to summer. When winter arrives, the plant falls into dormancy and growth slows, thus fertilizer treatments should be stopped.
When watering your plants throughout the growing season, you can use a water-soluble fertilizer. You’ll only need to fertilize the Rubber Tree once a month to keep it happy and healthy.
- You can use slow-release granules, sprinkle them on top of the soil in the container, and fertilize just every couple of months. When you water, slow-release fertilizer slowly breaks down into the soil, and most formulations last two to three months before you need to reapply. Always apply the product in the amounts and at the times advised by the manufacturer.
- You might use a half-strength water-soluble houseplant combination. Simply combine the product in your watering can and use as usual when just watering.
- It’s also possible to employ a balanced water-soluble blend for both indoor and outdoor plants. Apply at half-strength while watering the RubberPlant.
Fertilizers have a propensity to build up salts in the soil over time, therefore flushing the soil to eliminate them is necessary. While Rubber Plants have a modest tolerance for salty environments, too much salt in the soil can cause the foliage to burn.
It’s simple to get rid of salt accumulation. If the Rubber Plant is too large to manage indoors, you can either take the entire container to your kitchen sink or bathtub to flush, or you can take it outside to flush. Allow five minutes for the water to trickle gently through the soil, washing off the salts. Allow the water to drain from the bottom of the container, then return it to its indoor placement.
In a watering can, combine 1/2 teaspoon 10-10-10 nitrogen, phosphorous, and potassium water-soluble fertilizer with 1 gallon of water. During the rubber tree’s active growing season, fertilize it every three to four weeks. Fill the pot with fertilizer solution and allow it to soak into the soil thoroughly. Fill the pot once more. Any solution that collects in the drainage tray of the pot should be discarded. Instead of watering, apply the fertilizer. When the plant’s development slows and stops in the fall and winter, stop fertilizing it.
Should I fertilize my rubber plant?
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.
What do you feed a rubber plant?
Your rubber plants will be ready for a nutritious food once a month has elapsed since planting. Give them what they want by feeding Miracle-Gro Indoor Plant Food once a week while they’re actively developing, an instant source of just the correct nourishment. Use 2 pumps for small pots and 5 pumps for larger pots to apply it directly to the soil and water as usual (over 6 inches in diameter). Always follow the manufacturer’s instructions before using any product.
How often should I feed a rubber plant?
The Rubber Plant (Ficus elastica) is one of the most popular Ficus houseplants. Rubber plant care necessitates a reasonable amount of attention. Rubber Plant thrives in a moist but well-drained environment with a decent combination of light and shade, as well as a fertilizer regimen that changes over time.
Rubber Plant Houseplant Care: Light Requirements:
Rubber Plant thrives in a wide range of conditions, from full sun to moderate shade. Plants should not be kept in rooms that receive direct sunlight throughout the day. Keeping the plant in a room where one’s shadow can readily be seen on the wall behind the plant throughout the day is a fair indication of a room’s proper brilliance.
Leaf loss is particularly typical in Rubber Plants that are housed in overly gloomy or drafty environments. Avoid drafty spaces near wide windows, air vents, and opening doors when growing Rubber Plant inside. When you’re outside, stay away from chilly, dark regions that get little direct sunlight. If leaf drop happens, stop fertilizing and transfer the plant to a warmer, more well-lit place until the leaf drop stops.
Rubber Plant Houseplant Care: Water Requirements:
Rubber Plants (Ficus elastica) need a wet, moist atmosphere to thrive. Rubber plants should be sprayed on a frequent basis, especially if they are in a hot environment. During the growing season, water with lukewarm water in a modest amount. Allow cold tap water to sit until it reaches room temperature, allowing chlorine to dissipate and reducing the shock that cold water can cause plant roots. Reduce watering during the winter months, keeping the soil moist but not soggy, as plants need less water during their natural resting season.
Excessive watering is usually indicated by yellow foliage. Yellow leaves are sometimes misunderstood by those who care for Rubber Plants as a symptom of insufficient moisture. If your leaves start to yellow, wilt, or fall off, stop watering and fertilizing until the soil is adequately wet and the symptoms go away.
Rubber Plant Houseplant Care: Fertilizer Requirements:
Apply a high-phosphorus fertilizer to the young roots of Rubber Plant to encourage root development. Apply a high nitrogen fertilizer every four (4) weeks throughout growth as the plant matures to produce a lot of foliage, since this promotes full and healthy foliage development.
Rubber Plant Houseplant Care: Pests & Diseases:
Mealybugs, scale insects, spider mites, root knot nematodes, and thrips are all typical pests that attack rubber plants. Leaf spots, crown gall, twig dieback, and Southern Blight are examples of pathogen (fungal and bacterial) concerns.
Rubber Plant Houseplant Care: Propagation & Potting:
Rubber Plants must be transplanted into larger pots on a regular basis. Failure to transfer pots as they expand might result in root damage, causing the plants’ growth to be stunted. Binding is required for stability and to keep the root ball tight for transplanting. As a result, each time you transplant Rubber Plant, make sure to use pots that are no more than one (1) inch greater in diameter. For each new potting, make sure to use fresh soil.
In the spring or summer, use bottom heat to root semi-ripe or leaf-bud cuttings. Seed should be planted in the spring at a temperature of 59-70 degrees Fahrenheit. In the spring or late summer, rubber plants can also be air layered.
How often should you water rubber plants?
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 can I make my rubber tree grow faster?
Don’t you already know what I’m about to say? So, let’s get this party started! “PROPER. PLANT. CARE!” says the narrator.
You guessed correctly. The most efficient strategy to encourage your Rubber Tree to grow quickly is to provide for all of its requirements. Light, water, nutrition, and space must all be taken into consideration.
Locate a location for your plant that receives plenty of bright, indirect light. Pull it back from the window a bit or draw a sheer curtain to protect the leaves from direct sunlight. While you’re at it, make sure the area where you’re going to put your plant has regular warm temperatures (above 65° F) and isn’t subjected to excessive hot or cold gusts.
It’s critical to have good watering habits. Only water as needed (when the top inch of soil is dry) and thoroughly, ensuring that the soil and pot drain well.
Rubber trees aren’t heavy feeders, but a well-balanced fertilizer will help keep the soil nutrient-rich. During the growing season, all you need is one treatment, diluted to half-strength, about once a month.
Finally, make sure your plant has enough area in its container. If the roots are brushing up against the container’s sides, pot up to the next size, leaving one to two inches between the roots and the pot’s walls.
How do you bring a rubber plant back to life?
It’s time to resuscitate the rubber tree plant once you’ve determined it’s getting too much water. Stop watering the plant right away and let the soil dry up. Wait until the soil is dry to a depth of 1 inch before watering the plant again. Remove the plant from the pot and the soil if you fear root rot has set in. To remove the discolouration, cut back any brown or black roots using scissors. White and strong roots are ideal. Repot the plant in a fresh pot with new soil.
Why is my rubber plant dying?
Rubber plants are recognized for being one of the easiest houseplants to care for because they are less sensitive to their surroundings than other houseplants. This isn’t to suggest that your Rubber Plant won’t struggle from time to time if its environment isn’t right for it, so keep an eye out for warning signs and treat them as soon as possible to keep your rubber plant alive.
Changes in light conditions, over- or under-watering, dry air, and pests are the most common causes of rubber plant death.
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 area.
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 fingertips as soon as you spot 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 establish a balance.
Reread the section on watering previously 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 badly pot confined 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 at 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 variety of reasons for your soil remaining moist 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 resting 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 quite 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 might 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 may make your home more humid by using a humidifier. Although proper watering is considerably more vital, 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, nonetheless, 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 adapt 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 good 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?
When you first bring a plant home, it’s common for it to drop leaves in a spectacular manner. The plant may be shocked by the change from 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 bring 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.
How do you save a fertilized rubber plant?
Houseplants might be harmed by too much fertilizer. Overfertilization can stunt plant growth and make them more susceptible to pests and diseases. It can also lead to the plant’s eventual death. Stunted growth, scorched or dried leaf margins, wilting, and plant collapse or death are all signs of excessive fertilizing. Plants that have been over-fertilized may develop yellowing of the leaves.
Salt accumulation on top of the soil can also be caused by too much fertilizer, making it difficult for plants to absorb water. Simply lay the plant in the sink or another suitable spot and completely rinse it out with water, repeating as needed, to alleviate over fertilizing and excess salt buildup (three to four times). Between watering intervals, make sure the plant has plenty of room to drain.
It will be easy to avoid using too much fertilizer on your houseplants if you fertilize just during active growth periods and reduce the dosage.
