We have grown grapes for the last 4 years and honestly haven't done much with them...they seem to care for themselves. We do cut out the dead vines but that's really it. I know there are lots of books out there on how to care for them with lots of different advice. But we have ours placed against buildings and they get consistent light watering from a drip system. Our harvest is abundant...so much so that we ended up selling bunches at the market last year! In addition, we made juice, jelly and froze a couple of pounds of whole grapes (for cereal toppers! MMMMM!) Good luck! We love our grape vines!!
