Apricots in general are not easily adaptable to climates unusual for a given variety, they may react by dropping the fruit buds and low fertility. In France, they have different varieties for every region.
I have about 6 or 7 fruits on this Afghanistan branch (grafted on a Tilton tree). This spring, Afghanistan bloomed later than all other apricot varieties in my orchard so I’m happy it set a few fruits. Next year, I’ll have more late-blooming varieties (Zard, Supkhani, Paviot), which hopefully will help pollinating each other.
