Universities often do not have the time to answer individual questions of such a nature. That is why they create Forum discussion sites like this. Many universities in the US provide agricultural extension service. Here are some articles on growing grapes and specifically Concord grapes in Texas and elsewhere. Will Concord grapes grow in Texas? - Ask an Expert https://aggie-horticulture.tamu.edu/fruit-nut/fact-sheets/grape-arbors/ This manual from Colorado State give very detailed information on grape growing. https://extension.colostate.edu/docs/pubs/garden/550a.pdf https://extension.umaine.edu/highmoor/research/growing-grapes-in-maine/ I hope these sites help. Happy growing!
After all the centuries that humans have been growing produce, there should be a database with all of this information somewhere. I am not asking for anything new or abnormal.
