ok i'm back~
I am also planting lemon balm(for~1 year(?)
I put it under a desk,(that means it's not very bright)it still 燶葉,
so 燶葉may br cause by "泥太濕->腐根"/too hot.
But if it 腐根,how can it surrive for ~1 year?
Thanks for your experience and suggestion. They look OK to me, so all you need to do is improve the English a little bit, on my suggestions.
Since some friends got other meaning, and it is so difficult for my to read the message initially
