I live in South Florida and my kids have grown two nice looking avocado trees from Hass avocado seeds. The seeds came from their grandfathers backyard avocado tree in California. It is unlikely the trees grown from seeds will produce fruit. It is also not likely that we can get scions from the original parent tree in California. I would like to find some nice Hass avocado scions to graft, but do not know where to get them. Is there a scion exchange for avocados or a place I can collect them for free or a small fee? Is there a way to ship/send scions safely from California to Florida? Any advice is appreciated.
