Hi, Kalen, It sounds like your mint is being attacked by a pest, possibly plant bug (yup, that is what it is called). The dots are damage from the plant sucking sap from the leaves.Check around for bugs/pests. If you are fairly certain this the culprit, you can get any number of chemical or organic sprays to deter them. Kathy C
I have noticed some tiny black specs on the underside of my mint leaves, since then I have seen them on the basil and sunflowers too. They seem to be surrounded by a milky substance, either that or the leaf is slighty thinner around the black dots. The dots are so small I can only see them because they are grouped. Does anyone know what these could be?

Its flowers are very attractive to butterflies, including the small tortoiseshell shown in the photograph. It is a native of moist banks in the south-west, but occurs elsewhere as a naturalised garden plant. It is one of the less invasive mints, but still needs plenty of space to grow.
