Mint - Why Are The Edges of My Mint Leaves Brown?
I placed some mint inside a large outdoor pot with proper drainage and a combination of Miracle Grow potting soil and last year's compost material.
Almost from the start, most of the leaves began to develop a brown, crispy edge. I can actually crumble the brownish part of the leaf and it feels just like a dead, dried leaf from a tree in the fall/winter.
The plant receives sun all day and temperature has been very hot the past month 80s - 90s. I water every day (maybe that is too much) as the heat seems to dry the soil each afternoon.
Below is a picture of one of the leaves.
Can anyone help me with this?
Thanks so much!
