Cold and exposed gardens
How can you encourage plants to grow happily in a cold exposed garden? The key is a shelter belt, which means a deep planting of dense trees and shrubs that deflect and absorb the worst of the wind.
The diagram shows how the wind is ‘broken’ by the trees, but is still allowed to pass through. Single tall trees are not as effective as the wind merely scoots underneath. So once you have a shelter belt, then the downwind side, should be able to develop a more sheltered climate allowing you to plant.
The second problem are frost pockets. Cold air sinks and fills hollows or dips with cold freezing air, if these areas are sheltered from the wind too, then the frost is deeper and more penetrating.
As we can’t control frost, it is sensible to try to only plant with frost hardy plants. Also ensure the soil is well drained as it is a combination of cold and wet that usually kills the plants.
