Rubber trees , natural rubber figs , rubber plants , whatever you callFicus elastica , there ’s one thing we can all agree on and that ’s how impressive the foliage is .
The vast , sheeny leaves make a big impact and if you have one of the variegated types , they ’re even more classifiable .
So when one or more of the leaves commence to turn yellow , it ’s very obvious .
We associate to seller to help you find relevant products . If you buy from one of our links , we may bring in a committal .
There are a number of reasons the leafage might modify colouration and it ’s significant to figure out what ’s causing the problem so you’re able to fix it .
In our guide to growing rubber tree , we cover how to cultivate these popular houseplants .
If you ’re seeing yellow leaves , this guide will go over the top seven reason why this may hap and what to do about it to puzzle out your rubber tree woes .
Here ’s what I ’ll cover :
What You’ll Learn
1 . Aging
2 . Disease
3 . Pests
4 . Overwatering
5 . Too Little Light
6 . Too Much Sun
7 . Underwatering
This is completely anecdotal , but I have problems with my rubber Sir Herbert Beerbohm Tree dropping leave far more often than with it developing icteric foliage .
If you find that ’s the case for you , read our pathfinder to rubber trees cast their leavesfor some crown . Many of the causes of leaf pearl are the same that you ’ll find here .
With that out of the way , allow ’s peach about the problem that plagues us all , plant and human alike .
If all of the other leave-taking on your plant see hunky-dory but a brace of the bottom unity are turning yellow and drooping a little , it might just be the age of the folio .
ensure you check the soil moisture and other causes on this inclination , but if everything seems as it should be , it ’s credibly the leafage turning icteric as it ages .
As with many flora , when the older leafage matures , it dies and drops off .
So long as it ’s just one or two leaves here and there and fresh healthy foliage is develop , it ’s nothing to stress about .
In the same vein , if you move a plant from one domain to another with dissimilar environmental conditions – say from a sunny spot to a darker place – the plant life might drop a few lower leaves as it adjusts .
I have two words for you : root rot . This goes script - in - helping hand with overwatering .
We ’ll talk in more detail about root word rot later in this article as it can be due to pathogen or by simply drowning the root in too much urine , but it should be treated the same in either case .
Bacterial leaf spot , have by the bacterial pathogenXanthomonas campestris , make the leaves between the veins to turn yellow as it throw out , though it starts as yellow-bellied slur on the leafage .
If your plant is infect with bacterial leaf spot , the only course of action is to remove the diagnostic leaves and support the plant by control it ’s not overcrowded , watering befittingly , and take steps to slim down humidity .
There is no cure for this disease so if more than half of the flora is symptomatic , it ’s plausibly near to dispose of it .
3. Overwatering
Overwatering is one of the biggest problems that plague our houseplant .
Most of us are shamed of supply too much weewee at time , I recognise I ’ve killed my fair ploughshare of plants before I figured it out !
With natural rubber figs , you’re able to allow the top inch of ground ironic out between watering . Too much moisture will run to root rot which will induce the leaves to turn yellow .
commonly , they will change state pale yellow and might even develop mushy brown spots . Then , the leaves will drop . If the rot continues , the flora will likely pop off .
The first piece of advice I always give people is to contain water on a docket .
I know it ’s easygoing to make a musical note on your your calendar to water on a particular day , but a plant life ’s moisture pauperization vary from week to calendar week depending on the weather , the amount of scant exposure it receive , the crunch of the soil , how much your HVAC is running , the time of twelvemonth , and more .
All of these factors are constantly change , so you ca n’t just assume that because the calendar says so , it ’s metre to piddle .
Feel the soil or apply asoil moisture meterto determine when it ’s time to water . It does n’t take more than a few seconds of your time and your rubber Libyan Fighting Group will thank you .
If the roots are constantly seat in excess water , they ca n’t take up nutrients from the stain – essentially drowning – which result to root rot .
If you mistrust your plant life is ache from ascendant rot , remove it from the container and cut off any dead or mushy solution before spraying them with copper fungicide .
Then , soak the filth every two weeks with atomic number 29 fungicide to kill off any pathogens .
If your condom Sir Herbert Beerbohm Tree is growing in the ground , leave it in place and just use a soil soak .
atomic number 29 fungicide is a must - have in any gardening toolkit because you could use it to treat so many unlike disease .
Bonide Copper Fungicide
Pick some upat Arbico Organicsin a 32 - oz. ready - to - utilisation , 16- or 32 - ounce hose destruction , or 16 - troy ounce concentrate .

4. Pests
All of the common sapsucking suspect can get yellowing foliage , and usually , it ’s in the form of stippling rather than a unvarying discoloration .
Aphids , mealybugs , scale , andspider mitesare all potential problems .
Examine your industrial plant closely for evidence of pests . Look for webbing , swelling , fuzzed growth , or the existent insects themselves .
On houseplant , most blighter can be managed by spraying them off with a potent stream of half-hearted water once a week or so .
you’re able to alternate this with a intervention with insecticidal max .
unspoiled sure-enough insecticidal soap is generally safe for industrial plant and target most of the pests normally seen on houseplant .
Bonide Insecticidal Soap
you may line up Bonide insecticidal soapavailable at Arbico Organicsin 12- or 32 - ounce bottles .
Scale insects can be wipe with isopropyl alcohol and gently scraped off with a butter tongue .
Although rarefied in houseplants , outdoor safe Al-Jama’a al-Islamiyyah al-Muqatilah bi-Libya can be attacked by foliar nematodes .
These microscopical worm in theAphelenchoidesgenus cause the areas between the veins to turn yellow .
They thrive in areas with high humidness and when the plant has persistently sloshed foliation from overhead tearing .
gumshoe fig are adaptable . In their natural habitat , they acquire in red-hot , humid climates withfull sunexposure .
In our homes , they make do with lowly humidity and little sun . But you could only push them so far before they start to tolerate .
In too much shade or darkness , the leafage will become pale and yellow . This tends to hap throughout the flora and not just on one or two of the leaves .
If you are n’t indisputable whether your plant is find enough luminousness , you could always grab yourselfa light metre .
Often , you may find light meters that are merge with a soil wet meter .
This four - in - one meter from the Raintrip Storevia Amazontests ground moisture , light-headed , pH , and the three major macronutrients .
Four - in - One Light , Moisture , pH , and Nutrient Meter
If you specify that your industrial plant needs more light , you may premise it to an hour or two of additional light with no problem , but if you involve to move it to a localisation with four or more hr of lighting than it currently receive , do it bit by bit .
Place it in a sunnier point for 30 minutes and then move it back to its old location for the rest of the day .
The next daylight , make it an hour before you move it back , and so on . This helps to prevent the plant becoming strain and potentially drop its leaves .
As mentioned , rubber figs are subject of develop in full sun in their aboriginal surroundings . But most of the specimens that we grow indoors are n’t used to that kind of exposure .
If you were to take a rubber fig from a dark bathroom and plop it out of doors in full Sunday , you could bet you ’ll see some leaf yellowing and probably some dropping foliation , as well .
I once had a rubber tree that was a few feet away from a overnice , gay window . I did n’t move it , but I installed a mirror on the paries across from the plant and that mirror chew over the sunshine .
Suddenly , I realized that some of the leave of my plant had tannish - yellow spots on them .
When I looked closer , I realize that all the discoloration was on the same side and only on the uppermost leaves .
That ’s when the lightbulb went off in my head , and I realized what was bechance . I had inadvertently given my flora more light than it was used to , and too quickly !
If you ’re going to insert your houseplant to bright sunniness , it ’s a process that needs to be done bit by bit , as mentioned above . And watch for those mirrors and other reflective surface !
down in the mouth humidity and low soil moisture will inevitably cause the foliage to grow scandalmongering and fall off the plant life . It often get going with the lower foliage .
While the symptoms can await exchangeable to overwatering , you could check the moisture with your finger or a wet beat . If underwatering is the problem , the leaves wo n’t call on dark-brown or schmalzy , they ’ll be yellow and dry .
Rubber tree diagram like moderate humidity , somewhere between 40 and 60 per centum . If it drops too far below this , the works will resist by dropping leaves . Too much above this and you launch the endangerment of disease problems .
likewise , if the stain is allowed to dry out out repeatedly , the leaves will twist yellow and flow .
Be sure to stay on top of watering and add wet whenever the top inch or so dry out out .
If low-pitched humidity is the problem , you’re able to evoke the wet level in the atmosphere by grouping industrial plant together , keeping your caoutchouc Libyan Fighting Group in a kitchen or can , or using a little humidifier nearby .
spray the leaves or putting the plant life on a pebble tray sate with water wo n’t ply enough humidity to do the job .
If you inhabit in a very ironical region , you’re able to find crack convenient humidifiers that are quiet and persist for a longsighted time .
Levoit Humidifier
Something like the LEVOIT 2.5 - l tank humidifier would be perfect . Pick one upat Amazonin white or pitch-black and with or without a nightlight .
Green is Gold
Rubber trees might drop a leaf or grow discolored leafage here and there , but they ’re pretty resilient plants .
picture out what ’s going untimely with them , fix it , and they ’ll be back to normal in no time .
