Although you may mother over and carefullytend your Dracaena plant , it could still amount down with a disease .
This can happen preciselybecauseof the attention you have given it , in fact . Unlike many other types of lush houseplant , these plants prefer allow the soil they ’re planted in to dry out between lacrimation .
lachrymation that is too frequent can get the roots to become vulnerable to diseases and rot , leading to symptoms including black stems .

Read on to learn how to prevent these diseases , and what to see for if your plant becomes septic .
Here ’s everything we ’ll cover :
What Is Causing My Dracaena’s Stems to Turn Black?
Several types of infections can have black stems in Dracaena .
Fungal Root Rot
Your flora may first let you know that it is infected by wilt severely . While your inclination to solve this problem may be to give it a lot of weewee , this could make the place even high-risk .
Paradoxically , wilt in Dracaena can bea sign of diseasethat ’s actually due in part to an overweening amount of water .
At this item , rotted , dim area may become visible on the middle of the shank .
While you are not likely to desire to prune open your short plant , if you do , you will find that the tissue paper inside have a brown discoloration if fungal contagion is the culprit .
Types of Fungi that Cause Black Stems
A number of species of fungus have been found around the world to cause stem rot on Dracaena . These let in :
Do n’t interest about this long listing . Just because a pathogen is active in Egypt does not inevitably mean that it will be a job for you .
My intention here is to illustrate the preponderance of these type of symptom in these plants when due to fungous pathogen .
At home in the US , Fusarium solaniis a vulgar fungus , and it is the coinage that ’s most potential to be a job topically .
What to Do with an Infected Plant
In possibility , you could transfer the plant life from its can and trim back the rotted roots .
However , if your plant has already progress to that point , and it ’s already badly infect , you will probably not be capable to heal it .
As painful as it may be , your best bet is to dispose of the plant and desexualize the pot with a 10 pct whitener solution if you want to recycle it .
Tomato Spotted Wilt Virus
There is another fearful pathogen that can afflict Dracaena plants , and it ’s known as tomato blot wilt virus ( TSWV ) .
Do n’t let the parole “ tomato plant ” in its name slang you . This pathogen can attack over 1,000 specie of plant life .
It is ever - present in some areas , because it can infect many native specie , widow’s weeds , and landscape plants .
TSWV has been known to cause C of grand of losses in a single greenhouse flower crop . And it can affect your houseplant too .
TSWV Spread
Without the littleinsects known as thrips , tomato spotted wilt virus would not be a problem .
Young thrips acquire the computer virus as they fertilize on pathologic plants . When they become adults , the insects can transmit the infection .
The computer virus requires living plants to survive , and there is no shortage of potential hosts given the enormous host range of this virus .
Symptoms
Although symptoms start appearing seven to 20 day after the thrip acquire the virus , it is difficult to diagnose .
This is because so many other kinds of organisms and stress to flora can mime or closely resemble the symptoms of a tomato spotted virus wilt infection .
Black or purple streaks on the fore can be symptomatic for TSWV infections on Dracaena . The plants may be stunt , and leaves may drop prematurely .
anthesis industrial plant may expose tintinnabulation or stripes , business , or colored patch on their flower petal .
Infected Plants Should be Purged
unfortunately , since this disease is so contagious and it may impact such a huge regalia of flora , you should throw out of your Dracaena if you think it is infect with this computer virus .
Black Stems on Dracaena are a Harbinger of Bad News
Several different sort of pathogens can cause your works to evolve fatal stems , ranging from a who ’s who of kingdom Fungi to a widespread and pernicious virus .
Unfortunately , by the clip your flora develops opprobrious stems , the condition is likely incurable .
you may prevent fungous infections bywatering carefully , and await for the soil to dry out before you water .
