But apparently it's not invulnerable.
Our mint had been looking amazing: full and luscious.
But now it's hardly a shell of its former self. It's yellowy leaves and brittle stems wither away and fall off. :( There are some little bugs in the dirt but they aren't easily identifiable.
Our plan... I believe... is to uproot them, wash them off, and replant them. But this probably won't be done between now and the end of May.
Here's hoping they survive!
