I tried grapes several years ago and they lasted 3 or 4 years. I pulled the last couple out and gave them to my father-in law. I tried what I thought were seedless green grapes from either Lowes or Home Depot and was disapointed to find they were seeded reddish (like flame), I did not have any trouble with disease but they just did not flourish.

I use the wire arbor I'd made for some 'butter bean' vines now.

Thanks Pjames. I'll try them and post my progress. I'm also trying blue berries. Hope you have a great harvet this year.
