Mandevilla Dying - Suggestion?
I have this mandevilla growing on a trellis, it came in a 3 gallon pot and looks like it is either connected or splitting with another mandevilla at the base. I planted this about a month ago and the left side has really started going down hill.
The left side (photos 1-3) is droopy, poor colored leaves, black, etc. While the right is doing fine. Not sure what is wrong!
Very new to this, in a zone that can handle them and what is throwing me is that the vine from the same pot on the same side of the trellis is doing just fine. Should I snip this at the base and just work on getting the right side to cover the whole trellis?
I am thinking this is a disease, since it's all getting the same amount of water and sun.
