Q.My 20 Year Old Vine Yields Ony 1 Or 2 Bunches Of Grapes If Lucky. Do I Need To Replace It Please?
It is planted against my garage wall in a southerly direction and I prune it to 2 buds in the dormant season. I was advised not to feed it as they do better without ?

A soil test will help decide if it needs fertilizer. Make sure the vine has full sun all along the vines. You won't get many grapes without it. Also, check the vines for disease or insects. It also could be a pollination issue. Some varieties need a second "pollinator" vine.
