Hi Alex, what varieties can you confirm to be dwarfed by grafting onto Piva rootstock?
I really love the flavor of Cac, but I also read it's a big tree. There are a few other biggies that have interested me over the years (I can't recall which offhand) that I thought would never work in my space. I've been hoping Piva might be a game-changer in that regard.
Thanks!
Piva is known to dwarf old Florida varieties and some mangos of Indian descent.
What I’ve found is it dwarfs some stuff, stunts other stuff, and does nothing to a lot of mangos. It doesn’t seem to do anything to Lemon Zest for example. We’ve actually discontinued offering graft orders on Piva rootstock because of all the variability, plus the stocks take a long time to be ready to graft to begin with compared to the vast majority of other rootstocks.
We do still sell Piva rootstocks though , and will probably continue to graft to them sparingly on our own time as an experiment
I would be pretty skeptical of its ability to slow down Cac. But I haven’t tested it out yet.
