I bought 3 persimmon trees with interstock .They ve been in ground since december.
They are growing slowly.
What is the reason for the interstock? Was a mistake made by the nursery?Compatablity reasons
with prefered varieties? Is it normal for persimmon grafted trees to have interstock?
Other possible reasons for this to occur?
Will the double graft affect the movement of the juices /hormones etc .of the tree thus affecting its growth and its
frut setting capability?
The root stock may be a full sized variety for hardy roots, the interstem for dwarfing, and the top for best fruit. I think that'd be the most common reason for an interstem. I think they're sometimes used if the rootstock and the top variety aren't graft compatible.

What variety are they?
Most likely it is the non astrigent one. Fuyu?
Thank you for the reply and help.
One of them looks healthy probably due to better mulching.The other two a bit dry.
Someone said to me that the grafting guys didn;t sell the first trees with the grafting with the A variety ,so the next year they used this as rootstock to graft the B variety onto the unsold trees.Does it mean that its going to have a growth problem if the two varieties are not much compatible?
Don't know about Persimmon but double grafting is common with pears as some pears are incompatible with dwarfing rootstock and thus are commonly grafted twice to get round this .
The idea of using stuff twice to get rid of old stock seems a bit over the top to me
