I have a couple of vines trained up an over a grape arbour I purpose built. One is a 'table' grape and one a 'juicing' grape. As Crash says, keeping them under control in the growing season is a job in itself. I'd say in a good year mine produce about 25-50lbs each and the birds/squirrels/chipmunks get most of those.
Does anyone still grow gooseberries?
