Need help with Mandevilla problem
posted this on the tropical forum, no one ever seems to respond over there....maybe you guys will be willing to help me.
I have 3 plants all planted in pots at the same time, on the same watering regime, more or less the same amount of sun etc.
2 are doing great, the other (photo attached) just suddenly went downhill....
If anyone has any suggestions to problem solve this?
