I've often read that one needs to plant more than one apple tree in one's
garden to maximise fertilisation. I presume the same thing apply to pear
trees, yes?

If so, should each of the two pear trees be of differing stains or the same
strain?

Can pollen from an apple tree pollenate a pear tree and vice versa?

(I already have two apple trees and would like to plant a single par tree,
ideally. I don't know of any other pear trees in the immediate vicinity.

Thanks...

This is from the Ken Muir site......

Pear varieties are separated into pollination groups according to when they
flower, starting with the earliest flowering varieties as group A, group B a
little later and so on. Varieties within the same pollination group will
usually cross pollinate one another because they flower at the same time.
Varieties in adjacent pollination groups will also serve as pollinators for
one another because in most seasons there is sufficient overlap of pollen
resulting from an overlap in the flowering period.

So you need to find out which group your tree is and then get another
different variety in the same group. Same thing applies to apples.

It is also worth noting that unless you are in a particularly sparsely
populated area in all probability unless you have particularly rare
varieties there will be trees near enough to be used by the insects that
are using yours.

Apples can not pollinate pears, but if you chose a self fertile variety you
can get a crop with just one tree, you will nearly always get a better crop
with a cross pollinator but pears are prolific croppers so usually you have
more than enough anyway!

So far only diploid (needing two pollinators) apples/pears have been
discussed. It is also worth mentioning that Bramley apple trees are
triploid, meaning that they need three trees for pollination. Bramley
is a fairly well known case, but there may be others.
