Grapevine Leaf Rust and Die Off
I have a Concord grapevine and it does not seem to be doing very well. The leaves are curled up and indicate a rust color. Normally by this time of year, the leaves are large and green, and I see groups of grapes starting. Very concerned that I will lose this plant, which has been here for about 35 years!
