I have a couple concerns with 2 different plants. The first is some black/grey mold that has grown on the vine itself. It is still early spring but we are getting some moisture this week. This is a 3 year old vine and had mold growing on it, it also almost looks as if the vine has split in a few spots. I can see some moisture leaking out of the cracks. This concerns me that this mold may be getting on the inside. I thought about spraying the vine with some foot powder (antifungal). Is this some mold I need to worry about? Should I spray my vine with foot powder? See picture of outdoor vines.
The second problem is my indoor grape plant. I tried to make a bansai out of it, but the leaves are constantly dying off. I tried to let it dry between watering, I tried keeping it the soil wet, I even tried giving it nutrients with the water. Nothing has cured this leaf problem. Any ideas? See picture of leaves
