Exposure decides the plant list before soil does
Many Wellington suburbs face harbour or Cook Strait exposure directly, while sheltered valleys just a short distance away behave completely differently — Kelburn and Karori's more sheltered pockets can support a noticeably softer, more varied palette than an equivalent aspect in Island Bay or Miramar facing open water. A garden design that assumes one district-wide planting approach will get some of these sites badly wrong, losing new specimens in their first exposed winter.
Wind is described in Wellington's own planning material as a major comfort, planting-establishment and detailing constraint on exposed sites, and the practical response is a palette built around wind-firm, salt-tolerant, low-profile species rather than taller, showier planting that looks appealing on the nursery bench but struggles once it's out in genuine coastal wind. Fast-changing weather compounds this: a calm design-visit afternoon can be followed within days by conditions that test new planting hard, so a Wellington garden design has to plan for the site's worst realistic exposure, not its best afternoon.
None of this means a Wellington garden has to look austere. Compact, wind-firm species used well can create genuinely layered, textural gardens — the constraint changes the plant list, not the ambition of the design.
01 · Cost drivers for Wellington gardens
What changes the price of planting here
Planting cost in Wellington is shaped as much by exposure and establishment risk as by the number of plants going in the ground.
Planning noteA smaller, genuinely wind-firm plant list matched to this property's real exposure typically outperforms a larger, softer palette that looks better on paper but struggles in its first Wellington storm season.

03 · Wellington-specific planting factors
What decides the plant list before appearance does
Harbour and Cook Strait exposure
Many suburbs face harbour or Cook Strait exposure directly, which calls for a genuinely wind-firm, salt-tolerant palette rather than planting chosen mainly for appearance.
Sheltered valley alternatives
Sheltered valleys behave differently from exposed ridge and coastal suburbs, and a garden in one of these pockets can support a noticeably wider, softer plant list.
Fast-changing weather
Wellington's fast-changing weather means new planting can face testing conditions within days of installation, which should influence staking and establishment planning, not just species choice.
Compact multi-use spaces
Compact multi-use garden spaces usually matter more than maximum area here, which affects how a planting plan is laid out around a smaller, well-used footprint rather than a sprawling one.
Close-neighbour boundary sensitivity
Compact sections and close neighbours raise boundary and staging sensitivity, which affects how tall structural or shelter planting can be placed near a boundary without becoming a neighbour issue.
04 · Before planting begins in Wellington
Set the garden up to establish through an exposed season
- Assess this specific site's wind and salt exposure, not just the suburb's general reputation.
- Sequence hardy, wind-firm shelter planting ahead of more tender or taller species where exposure is real.
- Specify adequate staking or anchoring given how quickly Wellington weather can change.
- Check access for delivering soil and plants, especially on steps-only or narrow-path sections.
- Sequence planting after any hardscape or retaining work, not before, so beds aren't disturbed twice.
- Consider boundary impact of taller shelter planting given how close neighbours typically sit.
05 · A worked Wellington scenario
An exposed front garden in Island Bay
One example of how exposure shapes a real Wellington planting brief.
Coastal-facing front garden, open exposure with no existing shelter
The front garden faces open water with nothing established to break the wind, so the plan leads with a low, dense band of wind-firm, salt-tolerant species along the boundary before anything taller is introduced further back. Rather than staking a handful of larger specimens against the exposure and hoping they hold, the design favours a genuinely low-profile palette suited to the site as it actually is, with height and softness introduced gradually toward the more sheltered area closer to the house. Soil in the exposed bed is amended for drainage given the site's aspect, and new planting is checked and re-firmed after its first few weeks in the ground, since a calm planting day here is no guarantee the following week will be equally kind. A small side courtyard, sheltered by the house itself from the worst of the exposure, is planted with a slightly softer, more varied selection, giving the owners one exposed street-facing zone and one gentler private zone rather than forcing a single compromise palette across the whole garden.
