thanks any ways

hi we get a powder called fish blood and bonemeal in the uk. it is a by product of the food industry.

I suspect you will have something similar. if not then a all purpose granular feed will work just as well.
welcome to GoY too.

I wouldn't recommend feeding a grape vine at all - they grow in very poor soil naturally.

I was once told the best thing for a vine was to bury a dead dog under it....

Well they certainly don't do that in the vineyards Steragram!
