ESPALIERS, in gardening, are rows of trees planted about a whole garden or plantation, or in hedges, so as to inclose quarters or separate parts of a garden; and are trained up regularly to a lattice of wood work in a close hedge, for the defence of tender plants against the injuries of wind and weather.
The trees chiefly planted for espaliers, are apples, pears, and some plums. See GARDENING.
