Wind increases water loss, stresses plants, and can physically damage foliage. Soil can dry out quickly, especially on slopes or in exposed terraces. Proper plant selection and design are crucial for survival and longevity.
A layered planting strategy reduces wind stress:
Plagianthus regius – Forms shelter for smaller plants.
Pseudopanax arboreum – Evergreen, flexible canopy.
Sophora microphylla – Drought and wind-resistant.
Corokia Yellow Wonder – Compact, bushy, and wind-tolerant.
Dodonaea viscosa Green – Strong, deep roots.
Olearia dartonii – Hardy, dense foliage reduces wind penetration.
Phormium tenax Green – Architectural, protects soil.
Austroderia richardii – Tussock grass that bends without breaking.
Leptinella squalida – Ground-hugging cover, prevents erosion.
Coastal wind requires salt-tolerant species:
Coprosma acerosa – Low-growing, salt-resistant.
Phormium cookianum Green – Thrives in sandy soils and wind-exposed sites.
Windbreaks: Use tall, dense shrubs perpendicular to prevailing wind.
Curved plantings: Reduce direct wind channels.
Dense clustering: Protect sensitive species and retain soil moisture.
Layer heights: Trees, shrubs, then groundcovers create a protective microclimate.
A well-designed wind-tolerant garden supports native biodiversity, reduces soil erosion, and thrives in challenging exposed sites when layered planting and appropriate species are used.
