I am having trouble with my mango plant. I have had it in a pot for several years now and I am living in UK, so I don't expect miracles....keeping it alive is satisfaction enough. However, most years it has had a burnt, black ring around the margins of the leaves after mid summer. I am not sue if I am overwatering or underwatering, its so difficult to tell in a large pot. Would anyone know if the damage on the leaf margins is.... dry atmosphere?....cold temperatures?....or water problems??? Thanks.
