Appox 3 years, they should be trimmed in the fall after a hard frost. You should drop the bunches for 3 years to allow the trunk to get strong and the roots to go deep. It also depends on the verity and where you are located.

Virtual grapes are quicker!

The first couple of years ours were quite small and it was into the fall, but as I started cutting them back and only allowing one vine, they got bigger and come earlier.

Mine took a couple of years. If you have a fish pond or frog pond nearby collect some of the bottom of the pond and put in on the base of the vine in summer. After a couple of doses of that, my vine just went beserk. The roots of the vine like to be cool so best planted outside. The top of the vine loves warmth and sunshine, the more the better. I trained mine into my conservatory. At the end of summer cut off all or most of the leaves so that the grapes get maximum sun - I was told this trick by a Portugese friend. Also cut back any other stems to one bud, which will grow next year. No matter how tempting, only allow one main stem. Hope this helps Linda, don't give up.

This truly depends on your care, and the soil, and the balance of the chemicals in your soil. Getting all these tested, is the main factor, and using good soil around the base of it, are major factors. Best wishes, J.

I live in Niagara Wine country in Canada. Takes 3 years and depends on light and soil drainage. The grapes here are aligned north/south axis to allow sun to hit the vines all day. There is also a lot of pruning involved.

Lots of sun,place used tea bags around the base,cut back the thin branches in the fall.

this will give the thick branches a boost in the fall
