I agree Steve. If he has a full size tree and a tree on dwarf rootstock, the dwarf will
bear fruit a few years before the full size tree.

....... I wouldn't bother with that. Your other tree is normal so your
soil is good enough.

..............as I said it is a hybrid with 3 different types of
apples,1 cooking the other 2 eating

.......That doesn't make it a hybrid, that makes it a tree with 3
grafts. So the tree doesn't have a name but the 3 varieties grafted onto
it would have a name if you knew what was grafted on. That doesn't
matter much at this point. I thought maybe it was one of the varieties
that has to get older to produce or had special pollination needs. Since
there are actually 3 varieties involved, the problem is something else.

and it does flower at more or less the
same time as the other one but they do not flourish to fruit and finally I
do not feel we are pruning too hard..........................

....... Maybe your tree that does produce well is a variety that tends
to produce well on a small/young tree. Maybe the other tree isn't and
just needs to get bigger to produce well. You didn't say if these trees
are young, or older trees with some size.

How does the 3 variety tree look? Is it as healthy looking as the other?
Are the leaves as nice and green as your other tree? The leaves aren't
smaller and stunted are they?
