Any variation in the colour of your plant should raise a red flag . Your calathea ’s brown foliage tip could bespeak a gadfly or disease infestation . However , this is not always the case .
The most common causes of brown tip on calathea leaves are dehydration , insufficient humidity , and erythema solare .
To remove the problem , soak your calathea , increase humidity , or move it out of lineal sunlight . Brown bakshis can also be triggered by insensate wound , fertilizer burn , poor city water supply , and pest plague .
you could remove the brown folio tips without harming your calathea .
However , this will only cover the underlying topic causing the Robert Browning of folio crest . I ’ll show you how to identify and resolve each potential progeny .

What is Causing My Calathea to Brown at the Leaf Tips?
The damage is principally on the dispirited leaves leads me to believe there is a nutrient deficiency . Could it be that it kills off parts of itself to receive nutrients and energy ?
How long has it been since you fertilized it ? Also , the leafage appeared in direct striking with the grease .
Perhaps the moisture from the soil combine with the humidness harmed the folio ? you’re able to move out the yellowing part ; I guarantee you ’ll forget about it .
Only be pertain if it continues . Also , keep in judgement that plant are n’t consummate in nature . We ’re all doing our best to grow perfect plant in our household , and you ’re doing a fantastic task .
The following are a few reasons why your flora might be stressed :
[1] Watering Stress
embrown at the edges or tips of the leaves is frequently an meter reading of deficient , unconventional , or temperamental tearing . In other words , your calathea is either receiving deficient or excessive water .
On the other hand , underwatering is more likely to stimulate brown tips in calathea than overwatering . desiccation of your plant can occur for a variety show of grounds .
The soil structure has been weakened – If this is the cause , the growing metier will no longer retain wet well .
This is especially true if you potted your calathea in a sandy growing medium and get the irrigation water drain too promptly .
As a result , your plant is n’t get enough moisture , which may explicate why the wind of your leaves are change state browned .
ascendent damage – When the leaf tips and edges turn browned , check to see if the radical have been damaged . If there is a lack of body of water due to ancestor damage , your calathea ’s xylem tissue can not transport nutrients , minerals , and food for thought to the extremes of the leaves .
This , mix with tissue desiccation , will stimulate the farewell to turn over brownish at the edges . Waterlogged or flooded growing sensitive can suffocate root word .
Perhaps the soil around the stem system has compacted , cause root injury . If the soil remains wet for an extended period of metre , your plant will develop root rot .
As a result , the roots will die back and unable to channel nutrient and water to the plant .
Constricted roots – scrutinise the solution scheme to ensure the root are not constricted . If the ascendant are too strained , they will be unable to seek wet in the dirt .
If your calathea has become root - adhere , you will acknowledge this . The roots can become too constricted if the growing medium has become too impenetrable due to an excess of dense Lucius DuBignon Clay content .
The same thing can hap if you pot your calathea in the untimely size container .
Because of the excessive heat , the soil is dry out too quickly – If the parting are toast up and the pourboire are browning , your calathea is hungry . One of the most vulgar causes is that the growing medium dries out much too apace .
In most cases , your calathea may have been parked in an to a fault bright location . Perhaps it is in direct sunlight . It could also be standing near a draughty warming vent , radiator , or in the south - face window sill .
You neglect to irrigate your plant – Calathea is a moist - loving perennial . During the high - increase bounce and summertime months , you should deeply irrigate it once a hebdomad .
If your works has chocolate-brown leaf tips , it ’s potential that you skipped one or two watering sessions . If you gave it too much water in the previous irrigation , the leaf top and bound will embrown more sharply .
An submerged calathea will also show the follow symptoms :
The best way to keep your calathea depend on what ’s causing the watering stress in the first seat :
[2] You Have Overfertilized Your Calathea
The high subject of plant food salts in the growing culture medium is another common campaign of leafage tip embrown in calathea . It ’s also possible that you used soil with a high salt cognitive content .
However , if the initial potting mix was right , there ’s a honorable prospect that salt buildup triggered by over - fertilizing is to blame for the brown peak .
Calatheas are heavy raiser , but if the soil intermixture is already nutrient - rich , they do n’t require much fertilizer . You may overfeed it with fertiliser in the false belief that it will maturate quicker and more lushly .
regrettably , overfeeding it can cause more harm than adept . If this is the case , the leaves will become gentle , floppy , and browned at the tips and edges .
The leafage tips are the first to sprain chocolate-brown . You may also notice some fertiliser salt scabs on the soil ’s airfoil .
If you notice dark-brown tips and leaf scorching presently after apply a heavy dose of fertilizer , the problem is most probable an excess of fertilizer salts in the territory . You must immediately cease feeding your calathea fertilizer .
If the common salt buildup is small-scale , you may palliate the problem by increasing irrigation frequency for a few workweek .
The best solution , however , is to flush the growing mass medium with distilled uncontaminating water supply . Repeat until the fertilizer salts have been washed out .
From April to September , feed your calathea a pee - soluble limpid fertilizer once a month . Fertilizer should be watered down to one-half strength before software , and feeding should be reduced when winter make it . ( germ : North Carolina State University )
[3] Poor Water Quality (Chlorine and Fluoride in City Water)
dross in irrigation water can also be bespeak by brown tips on calathea leaves . Most probably , you ’re irrigating your plant with water directly from the faucet .
The issue with city hydrant weewee is that it often contains high levels of fluoride , chlorine , and deposit . These impurity have accumulated in the soil or on your plant as a solvent of buffer tap water over time .
brownish leaf tips may also signal a salt buildup from fertilizer or softened water over time . Fluorides frequently damage the leaves and roots of Calatheas . This is common if you only use body of water from the bottom .
muted city water may make the tips of your calathea leave to brown . That is why to keep your calathea happy , you should switch to filtered or distilled water .
You should consider water your calathea from above on a even basis . This will aid blush out any chlorine , fluoride , or other water softener buildup .
It is also a skilful idea to repot your calathea every 2 - 3 years in the spring . I ordinarily use African violet - specific potting mixes .
[4] Lack of Humidity
The front of dark-brown tips on your calathea can also indicate a want of humidness in the surrounding air .
Calathea , like most herbaceous plant aboriginal to the Brazilian tropics , favor to raise in areas with gamey humidity . You must ensure that its environment intimately resembles the jungle conditions of its aboriginal habitat .
As a result , if your living surround is passing dry , the leaves of your calathea will rapidly dry out and turn brown at the tips . Typically , this is followed by wilting and curling of the leafage .
The situation is exacerbated in the wintertime when fundamental heating system or air conditioning is turn on .
Calathea is a humidness - loving tropic . You must boot humidity levels around your plant by :
[5] Calathea Burnt Leaves Due to Excess Sun Exposure
Calathea plants thrive in medium to bright , filtered light . It is quite tolerant of low - brightness level conditions , but it can not resist excessive direct sun .
If you place your calathea on the windowsill of a Confederacy - veneer or Benjamin West - face window , you are invite sunburn . The tips of the leaf will become crunchy , wry , and chocolate-brown .
The yellowing of leave of absence is ordinarily the first sign of overexposure to sunshine . However , if you move your calathea suddenly outside or to a location with direct sun , it may develop scorched tips .
The worst office is the windowsill , because the glass can beam and magnify estrus , causing leaf scorch .
Move your calathea to a placement where it will get dappled light source . Ensure it is shielded from unmediated sunshine , especially during the red-hot time of day of the afternoon .
Move it three to four feet aside from the south - facing window so that burnished , indirect sunlight can make its leaves .
[6] Cold Injury (Drop in Temperature)
Another common causal agency of brown tips in tropical plants , include calatheas , is cold damage .
To keep your calathea thriving and happy , you must provide consistent warmness . It favour warm temperature graze from 70 to 85 ° F ( 21 to 29 ° C ) .
temperature below 55 ° F ( 13 ° C ) can cause cold grievous equipment casualty to the foliage . Calatheas are not accustomed to drafty , cold , or frosty conditions , and they will react aggressively to stress make by a temperature drop .
Cold damage symptoms , like piss focus , will appear first in the leaf ’s extremities . Both the leaf tip and the leaf edges will become scorch or browned .
[7] Pest Infestation
If pest infestation is the first matter to come to your mind when you see brown tips on your calathea , you could be right . tick your plant for defendant like spider mites , fungus gnat , mealybugs , and aphids .
Some of the bugs feed on the edge and tips of the leaves , causing the tissue to bend glowering brown . See if you could find other clew , like pitchy mould or a ill-humoured black layer on the leaves .
As before long as you notice sign of pest on your calathea , treat it immediately by spray it with a natural pesticide like neem oil .
You should treat pest infestations as presently as you discern them . To get rid of calathea vulgar glitch :
Should I Cut the Brown Tips Off My Calathea?
you may contract the browned foliage crown off without suffer your calathea . Instead , this will encourage your flora to grow novel , goodly foliage .
Sharing is care !
