I was so excited to find those little leaves! I practically danced when I found 'em...my dog thought I was losing it, I think...
Your infected. You have a life-long disease now. It's called gardening.

I have been finding baby leaves on all my plantings of lemon balm this week. Even the one that the unknown critters attacked the worst. I made 5 plantings out of what OT sent me. Two of those have doubled in size now!!! Keep in mind, my growth season is a bit ahead of yours too though.
