dark-brown edges and tips in your calathea can stand for that your plant has water and humidness progeny . However , urine way out may not be the only reason why your plant is turning dark-brown , so , it ’s of import to determine the job to apply the right repair .
chocolate-brown edges and tip on calathea leaves are due to lacrimation using surd piddle . Calatheas are extremely sensitive to the minerals and salt found in water tap water . The accumulation of chlorides and fluorides in the pot pulls water from calathea , make a drought - same condition that causes brownish tips and edges . You will also notice a band of blanched deposits on the soil telephone line .
piquant body of water also increases calathea ’s susceptibleness to insects and diseases . Coupled with humidity below 60 % , calathea edge and tips turn browned .

Use rainwater or distilled urine this time , and on a regular basis mist the leave .
Why are my calathea leaves turning brown?
Browning leaves can lead from one or a combination of several factors . In their native base in South America , calathea thrive as underbrush , which means they ’re protect from supererogatory visible radiation . In addition , the prevail humidity and rain enhance their growing and beauty .
Here are some of the intellect your calathea leaves are turning dark-brown :
Over-fertilizing
Excess fertilizer has the same impact as short pee quality . fertilizer have varying degrees of phosphates , sulfate , and carbonates that will accumulate on the soil if there ’s no proper drain . Over - fertilizing causes plant food sunburn , whereby accumulated salts in the potting soil cause calathea to have brown edges and tips .
Although calatheas do not need frequent fertilizer , knowing the correct amount of fertilizer and the nitrogen , phosphorus , and atomic number 19 proportion are critical for respectable leaf . I will explicate more later on how to fix over - fertilizing .
Low humidity
Low humidity is the leading cause of chocolate-brown edges in calathea . Since they are aboriginal to the South American tropics , calathea can only expand in area with humidness above 60 % . Dry air curb petty moisture to keep calathea healthy .
In down moisture atmospheric condition , calathea will sag and wiltas its cell desiccate . The leaf will eventually decease at the leaf margins .
Although increasing humidity indoors can be a challenge , improve moisture conditions in your home can help oneself revive the brown edge and bakshis for mostvarieties of calathea .
Water quality
Although most masses practice tap urine tocare for calathea , no botanist would advocate it . While some people may see success with their watering , tap water from other places like Perth and the United Arab Emirates comprise many salt and minerals . fade out salts such as chlorides and fluorides have significant damage to calathea .
Therefore , water quality is key to the tenacious - term survival of calathea . If your calathea edges and tips flex brown due to saline water , you may also mark a ring of blank deposit in the pot and around the drain hole . The accumulation of Strategic Arms Limitation Talks in the potting soil make osmotic pressure , pull water from the plant get the parting to plow Brown University .
Overwatering and underwatering
Overwatering and underwatering calathea can importantly damage your plant . Early signs of damage are yellow or brown and crispy calathea edges and tip . Overwatering is arguably the leading causa of death to houseplants because waterlogging cuts off oxygen from the soil and drowns calathea roots .
You ’ll know your plant life is overwatered when the filth is constantly sloshed to the mite . Calathea leaves start to bend yellow , and you may also notice lenient , spongelike stem . On the other helping hand , underwatering causes drouth - similar condition .
Temperature stress
Temperature extremes can also have a substantial impact on tropical flora like calathea . Cold drafts and warmth stress interfere with the plant ’s biologic procedure . For instance , heat strain encourage transpiration and evaporation , drying up the dirt and sear the plant , and forcingcalathea leaves to droop . finally , the prayer flora ’s leaves will develop chocolate-brown bound and tips .
Exposure to direct sunlight
Direct sunshine fade away the beautiful colors on calathea leaves . to boot , unmediated sun raise soil and air temperature . luminousness beyond 1000 luxcan cause significant harm to calathea leave , make them plough dark-brown start from the edges and tips ..

3. Flush out excess salts and irrigate with soft water
We have seen how raw calathea is to saline water . In the wilderness , calathea uprise right with rain . Unlike hard tap water , rainwater is soft .

The effect of temperature on calathea is also influenced by exposure to light . Although the plant want shining light , the igniter should not strain the plant life directly . or else , dribble out excess light . If the temperatures are high , root elongation reduces , the flora stunt , folio colour fade , and eventually dries up .
