I had my landlord babysit my beautiful baby lemon mint plant. When I gave it to her 3 weeks ago, it was deep green with no brown spots and rigid stems (no drooping).
Now, it's a very pale green with a bunch of brown spots, drooping stems.
She said she watered it daily but when she gave it to me, the soil was very dry (she even said she just watered it).
What caused this?
