Those grapes are gorgeous. How old are they?
My cousin brought back cuttings from Macotera, reds/whites...I started some, 24 are now growing, year 3, but they did suffer some damage from deer last year, so I think that set them back. A few did make fruit this year, but barely.
Do you fertilize your grapes, give them much water???
¡Muchísimas gracias!
