Mango Leaves Turning SOLID Brown!
I have some mango leaves that are turning brown. Or rather, it is a color between maroon and brown. And the pigment is a good degree darker than my camera illustrates.
They start to quickly and softly fade from green to brown until they become a solid brown color. No patches or anything. Just solid brown. Most of the brown leaves still appear otherwise healthy. Other brown leaves appear somewhat contorted and crumpled. A minority of my green leaves also appear somewhat contorted and crumpled. What might be causing this. What is a possible solution? Roughly 8% of my mango leaves are brown.
The plant has been there since the beginning of the year. This problem dates back as far as I can remember (in other words, I don't remember when it started). I've tried a variety of watering patterns. I recently used SuperThrive twice, as well as installed some fertilizer stakes. There hasn't been much change at all. It is planted in an area which has full sun. I've posted pictures of the plant as well as the ground on which it is planted.
