2 grape vines, 2 problems. Pics!
I have two grapevines.
One is green grapes (not sure what exactly they are) and the other one is a combination of concord and riber.
The "green grape" grape vine has 3 weird issues. The first is it has "chicken pox", some missing grapes in each bunch and I just noticed an odd shaped vine of leaves growing from the main vine. (also affected with "chicken pox") These aren't the typical grape vine leaf.
The second vine, "concord and riber" grape vine has missing grapes from each bunch and is rotting halfway through.
The "green grape" vine is over 20 years old and the mix of concord and riber is about 2 years old. What can I do to produce fuller bunches without missing grapes and rid them of the chicken pox and rot?
