There are over 800 metal money of Ficus , include well - known trees like the rubber eraser tree and the weeping Libyan Fighting Group . These tree , which are native to India and Asia , are have intercourse for their glossy , leathery farewell that seem to unload every time their surroundings changes . However , if your ficus leaves are turn dark-brown at the top , it ’s probably due to moisture problems , a want of nutrient or disease .
Step 1
Ficus plants are native to tropical areas and call for medium to high humidness . If the leaves are turning yellow or developing brown tips and margins , they may be suffering from dry air . A room humidifier will add wet to the airwave , or you may place your tree container on a tray of gravel . Add water to the tray , but keep the level of the water just below the top of the crushed rock layer so your Sir Herbert Beerbohm Tree is n’t sit in water .
Watering
Improper watering is another cause why leaf tips turn brownish . Ficus trees should be watered with way - temperature pee until the H2O pours through the drainage holes . Drain off excess water in the tray . Most genus Ficus plant should be take into account to dry a trivial in between lachrymation . One elision is the crawl Ficus carica , which postulate to be water as soon as the surface of the soil prohibitionist .
Step 2
Fertilizing
A lack of smoothing iron or atomic number 19 can also turn leaf tips brown . Iron deficiency also induce older leave to white-livered , and brown areas may appear between the veins or on the border . Your tree will also produce few leave . Symptoms of potassium deficiency include the show of numb smear between veins and at the tips of the leaves . fresh leave will be modest and scandalmongering with fleeceable vein . In addition , leaf may strike down . Exposure to chlorinated or fluoridated water supply can also cause browning . even the soil to take excess fluoride from the soil . genus Ficus Tree should be fertilized every three or four weeks during full stop of active growth . The strength of the fertiliser should be half what is recommend on the recording label .
Anthracnose
Anthracnose is a fungal disease that induce moody brownish spot to seem anywhere on the parting , including on the bakshis . face for slightly sunken spotlight with dark brown margins . As the disease progress , large areas may ferment brownish , and the leaves will degenerate . Masses of yellowish spores recrudesce in the pathological area . check anthracnose by removing diseased leave . forfend overhead watering and reduce stress from water and heat .
Botrytis
Botrytis blight is a fungous infection that causes browned spot with concentric rings to seem on the foliage gratuity or between the foliage and sheath . It ’s principally a problem for rubber works , during nerveless weather . As the disease move on , touched areas wilt and crack up . Grayish - browned fungal threads and spore develop on the place when the humidness is high . The spores are spread by wind and weewee and may taint salubrious leaves if they are wet . Control botrytis by hit deadened and pathological leave and burn or inter them . Fungicides can be applied as a protectant .
Cercospora
Cercospora is another fungous disease that can make genus Ficus leave of absence to die , starting at the baksheesh . Look for reddish - brown spot on the leaf , specially along the allowance and leafage tips . As the disease progresses , the spots grow bigger and the nerve centre of the spot turns light brown with a dark-brown border and yellow nimbus . Control cercospora by removing morbid farewell . nullify getting the leaves squiffy , and prune to ameliorate line circulation and encourage drying .
