Kong coleus is dying---help!
I bought a gorgeous, healthy kong coleus last summer, but it is not doing well now indoors. I have tried it in several windows, but the stalks keep turning this deep brown that starts at the roots and goes up, gradually turning the stalk brown. It's down to three stalks, and I'm at a loss what to do. I just asked a friend with a big picture window to "foster" it, since his home is warmer & gets more light than mine. I know it's a low light plant, but it's BEEN in low-to-moderate light with no improvement.
Please, any help would be very appreciated :)
