Will you like to suggest me to grow grapes in my backyard?

In some point it seems doesn't make sense to me that you are going to change your house (If i'm not wrong,you means moving to other place) some day after you have your graps grown in your back yard. But if i look at another positive way is that you may sell your house for higher price because of an extra grap farm. However ,the most important thing is you need do some research on internet in order to learn about how and what is the proper way to grow graps. Well,wish you good luck.

First thing would be do the atmosphere of your area is good for grapes growing. If yes, they go ahead. This is good idea. One more thing you have told that you will leave the present house after 3 years, then who will eat the fruit. This will be just social work. Though it is good to grow fruit.
