Is it advisable to clip off first-year grapes so they grow back larger

Question

I am new to growing grapes. After 2 years I have a grape crop but they are very small

Answer 1

Here is a good Extension fact sheet about growing grapes in the home garden. It suggests the first harvest be during the third season. I also included an article from our website. See if these help:
