I am starting to see holes and brown spots on all of my plants:
41+ Mint Leaves Have Brown Spots. Hi marlene, brown spots are signs of bacterial infection from the overgrowth of microbia that naturally exist in the soil. I have read other posts but the pictures don't really seem the same.
Alternatively, you can try these. While diseases are not common, occasionally the plant's leaves can develop brown spots. Also known as phudina, pudina, fudina.
It doesn't seem to be mint rust because there are no rusty orange spots or lesions.
Application of mint paste made by crushing mint leaves on your skin, removes dark spots and pigmentation that tend to occur in the process of ageing. Compounds found in peppermint leaves have been linked to inhibiting enzymes that promote tumors. How do i treat my mint and is there a way to get rid of whatever is causing this? Small, whitish, slightly raised spots that turn reddish orange or brown.
