What do you think is wrong? They are in sun, I water frequently and fertilize too. They just keep growing huge grape leaves and no fruit. Shouldn't they have blossoms by now?

OK, nevermind. Apparently not many grape growers on here. Anyway, I figured it out. Too much fertilizer. Solved my own problem.

I grow grapes and have for many years. Concords are the best for juice and Jam. We used tio grow them in white and black, when I lived in CA. Now I grow only Interlaken. I'm glad you solved your problem, I was going to ask how old they are. Normally it will take at least 3 years to fruit, and then only if pruned properly.

A few ideas
Are you pruning them in fall?or early spring?
You may be removing fruiting wood in an attempt to keep them neat
they make grapes on 1 y o wood- if you cut that wood- you won’t have grapes for a year.
Concord can get unruly- the fruiting canes grow down vs wine grapes where the canes grow up! So you need to put them on trellis.
Sorry if you already know that
Just realized that you are in Arizona- your grapes may not have enough of winter chill- depending where you are in AZ

Long pdf- could be helpful to scan through?

Maybe this is better?

Even without grapes, the vines are decorative! My in-laws had a grape arbor with a picnic table underneath. It was beautiful!

Yes, they are nice, but it's the grapes I want. My nursery man said in Oregon he grew grapes at a vineyard and I am probably not watering deeply enough. That, along with over fertilizing, probably means no grapes this season. Live and learn in gardening.

You need to give them potassium as a fertilizer. I gave them both bone meal and blood meal. Blood meal is for leaves, bone meal is for fruit production.
