Gardening in Oceania: guide for New Zealand and Australia

Oceania: the land of reversed seasons

For European gardeners Oceania is a fascinating mirror. Christmas falls in the middle of summer. The longest day is around 21 December. You plant bulbs in March and harvest tomatoes in February. It sounds confusing, but the fundamentals of gardening remain the same — only the calendar is flipped.

Australia and New Zealand together offer an incredible diversity of climates. From the tropical north of Queensland to the temperate south of Tasmania, from the arid Australian interior to the lush green west coast of the South Island — here you find virtually every climate type on earth.

New Zealand: green and temperate

New Zealand has a mild, ocean-influenced climate that shares surprisingly much with British weather. Moist, green, with soft winters and cool summers. Auckland on the North Island is subtropical; Christchurch on the South Island resembles the climate of southern England.

Native New Zealand plants

New Zealand's flora is unique. Pohutukawa (the "Christmas tree" that blooms red in December), silver fern (Cyathea dealbata), Hebe, Phormium (New Zealand flax) and Corokia are all beautiful garden plants gaining popularity in Europe.

Rimu, kahikatea and totara are majestic native trees. The nikau palm is the world's most southerly palm and withstands temperatures down to -5 degrees.

Australia: from tropical to arid

Australia is a continent of extremes. Sydney enjoys a pleasant subtropical climate. Melbourne is more temperate, with four distinct seasons. Perth on the west coast has a Mediterranean climate. And the interior — the outback — is one of the driest places on earth.

Australian native plants

Australian native plants are beloved worldwide. Eucalyptus offers scent and structure. Grevillea attracts honeyeaters with spectacular flowers. Banksia is sculptural and flowers for months. Callistemon (bottlebrush) is indestructible and versatile.

Kangaroo paw (Anigozanthos) is one of the most striking garden plants in the world — velvety paws in red, yellow and green found nowhere else.

Water: the Australian obsession

Water restrictions are a fact of daily life across much of Australia. Drip irrigation, rainwater harvesting and choosing drought-tolerant native plants is not a trend here but a necessity. The celebrated Australian native garden — a garden entirely planted with indigenous species — is the answer to decades of drought.

In New Zealand water is less scarce, but sustainable water management is becoming increasingly important as the climate changes.

Fire-safe gardening

In Australia bushfire prevention is a crucial part of garden design. Maintain a defensible space around the house: no combustible plants within 10 metres, use gravel as mulch instead of organic material, and choose plants with a low fire risk. Succulents, lawns and broad-leafed evergreen shrubs are safer than eucalyptus or cypress.

Seasonal calendar (southern hemisphere)

September–November (spring): Plant everything — perennials, shrubs, trees. Sow vegetables. Gardens come alive after winter.

December–February (summer): Bloom and harvest. Watering is the priority in Australia. Enjoy long warm evenings in the garden.

March–May (autumn): Plant bulbs for spring. Compost. Transplant trees and shrubs while the soil is still warm.

June–August (winter): Pruning season. In New Zealand light frosts occur in the south. In Australia it is the best time to plant citrus trees.
