An effective windbreak can be most useful in reducing wind damage. The aim is to make a screen which filters the wind, rather than a solid barrier which often causes 'eddying'. Research has shown that a windbreak will protect an area downwind of approximately ten times the height of the windbreak.

PLANTS FOR WINDBREAKS

For tall windbreaks, we recommend planting three rows of trees with 3ft (90cm) between rows and 5ft (150cm) between trees. In later years, the windbreak may be thinned. For windbreaks of 15ft (5m) or more in height, we suggest the following:

Poplar, Lombardy
Poplar, Robusta
Poplar, White

If you wish to include an evergreen in the windbreak, Leyland Cypress or Thuja Plicata Atrovirens planted 10ft (3m) apart with 3 Grey Alder in between is often recommended. If an evergreen windbreak is required, use Leyland Cypress or Thuja Plicata Atrovirens planted at 7-10ft (2-3m) intervals in two rows 6-8ft (1.8-2.4m) apart, or a single row 6ft (1.8m) apart.

For small windbreaks, Grey Alder is reliable planted 2-3ft (60-90cm) apart in a single row, although many other hedging plants can be equally effective.
