Natives of the warm
regions of the Mediterranean, pears require greater
warmth than apples for the fruit to ripen correctly
and so attain their full flavour and keeping qualities.
Pears require the sunniest places in the fruit
garden, where they may be grown as standards or
bush trees and in the pyramid and cordon form,
requiring similar culture to the apple in their
pruning. Pears are, however, at their best where
grown as espaliers or in horizontal tiers, the
arms being either fastened to a wall or to strong
galvanised wires supported by posts at intervals
of 240cm (8ft). Espaliers may be grown in the
open, possibly alongside a path, or to divide
one part of the fruit garden from another, but
it is important that they have full sun.
