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.


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.


You might find these of use.
