At first I noticed yield dropped considerable, the grapes dried up on the vine. Then one vine died, then the yield on the others dropped and this year there were no grapes only further die back of the stem.
I am a newbie to this site . I have been back yard vineyard for some time now...never saw this happening. Could someone help me identify what's going on here?
I need some help identifying this problem. I saw it a year ago when my yield significantly dwindled. On examining the vines I notice these aerial like root symptom all over each vine:?
