Hey!
I'm thinking of top working a second jiro fuyu tree since I already have the one big tree and don't need 2.
I don't think I need more than 1 or 2 sticks max.
I grow from seed but I do have some cultivars
Pears:
Korean giant pear
Honeysweet
Peach:
Hale Haven

Apples:
some kind of popular NJ orchard apple, I have no idea what it is but it's grown in orchards around here so probably disease resistant (maybe McIntosh?), seedling of a "hidden rose" apple no fruit yet

Plum:
Seed grown, probably a black beauty/ asian plum

Cherry:
Rainer, Royal Anne, Carmine Jewel (bush cherry)

Apricot:
Seed grown, no fruit yet
Kiwi:
Issai
Blueberry:
Reka
Feijoa:
Probably a seedling. Fruit is good, skin isn't bitter just sour.

Poms:
Afganski (I think you have this one from me!), other ones are too tiny to cut
PawPaw:
Al horn's, Lehman's Chiffon, IXL, Tropical Treat (these are new grafts so will have to check how much can be cut)
