How come my grape vine doesn't produce grapes? Does it need pollenation?

There was a grape vine when I moved in, its been about 6 years now although I have never seen it produce grapes but it grows tremendously every year and I cut it back every year. I recently bought a new grape vine and that one has already produced grapes. I noticed the leaves are different but both are bright green leaves. Do grape vines need to be pollenated or is it too old or what? Any advice would be great, thanks!!!

they have to be old, 10-15yrs, and when they start, need alot of water.
Reply:Grape growing is an art form.


They are picky plants that need proper soil and lots of attention.


Consider calling a grape grower in your area and asking questions. There are many websites about the subject. Books too. Go to the library, it's free and the employees can help you find what you're looking for.

Reply:What they need more than anything is fertilizer, I dont think they need pollination, you should be able to see the grapes form in the spring you should also be able to see a very small flower in front of the grape thats forming. At this time you cant shake it, or cause little flowers to fall before their time. A grapr vine should produce evn asmall amount from the first year. If you dont see these things happening the vine may even need to be grafted, (a piece taken from another vine and grafted on to yours)
Reply:If your new grape vine has already produced grapes then pollination is taking place ther in your area. Perhaps your old grapevine is not compatible to your climate. Perhaps the small grapes are being frosted before they can become grapes. That happens to mine here in Texas sometimes. Or maybe you are right about the pollination. Certain grapes are self pollinating while others are not. Do they bloom atthesametime
Reply:all plants are male and female, the one that is producing grapes is a female, are you pruning the other vine at the right time of year? There are certain times to prune them and you might be cutting them when they are making there blooms. Look up when to prune them. Otherwise just keep enjoying your plant.
