One of the most common questions we hear at Greenmachine is:
“When is the best time to plant NZ native plants?”
The short answer is simple:
👉 NZ native plants can be planted successfully at any time of year.
Native plants are naturally adapted to New Zealand’s diverse climate—from coastal salt spray to alpine cold—making them tough, resilient, and forgiving. While certain seasons offer ideal conditions, planting natives isn’t restricted to a single window.
This guide explains how each season affects planting, what to expect, and how to care for your plants—so you can buy and plant with confidence, whenever you’re ready.
New Zealand native plants evolved in challenging environments, which is why they:
Tolerate temperature changes
Handle wind, rain, and dry periods
Establish well from container-grown plants
Require less fertiliser than exotic species
Because our natives are grown in containers at the nursery, their roots remain protected, allowing them to be planted year-round with the right care.
At Greenmachine, we grow hardy, well-established native plants suitable for planting in every season.
New Zealand’s mild climate means planting is possible throughout the year. Each season simply requires slightly different care.
Spring: September – November
Summer: December – February
Autumn: March – May
Winter: June – August
Let’s look at how planting NZ native plants works in each season.
Spring is traditionally one of the most popular times to plant.
Warming soil encourages root growth
Increased daylight supports new foliage
Regular rainfall helps establishment
Spring-planted natives often show visible growth quickly.
Late frosts in cooler regions
Dry winds that increase water needs
Water thoroughly after planting
Apply mulch to retain moisture
Protect young plants if frost is forecast
Common spring-planted natives:
Griselinia, hebes, kōwhai, pittosporum, flaxes
Many gardeners worry about planting in summer, but NZ native plants are well adapted to warmer conditions.
Warm soil promotes root development
Container-grown natives transplant easily
Many natives naturally grow during dry periods
Summer planting does require consistent watering, especially in the first few weeks.
Water early morning or evening
Mulch well to reduce evaporation
Avoid planting on extreme heat days
Summer is a perfectly suitable time to buy and plant native plants—just support them while they establish.
Autumn is often considered the ideal season for planting native plants in New Zealand.
Soil remains warm after summer
Cooler air reduces plant stress
Increased rainfall supports root growth
Plants focus on establishing roots over winter, leading to stronger spring growth.
Plant early in autumn for best results
Mulch to protect roots through winter
Reduce watering as rainfall increases
Winter planting is often overlooked, but it can be very effective—especially in mild regions.
Plants are not actively growing above ground
Reduced stress during transplanting
Natural rainfall helps settle plants
Heavy, poorly draining soils
Areas with regular hard frosts
Ensure good drainage
Avoid planting during frost or waterlogged conditions
Mulch to protect young roots
Many native trees and shrubs establish extremely well when planted in winter.
Thanks to modern nursery practices, you don’t need to wait for a specific season to plant natives.
At Greenmachine, our native plants are:
Container grown
Well rooted
Hardened in Southland, to NZ conditions
With correct watering, mulching, and site selection, planting natives is successful in every season.
This makes year-round planting ideal for:
New builds and landscaping projects
Coastal and restoration planting
Home gardens planted in stages
Autumn and spring are ideal, but native plants can be planted successfully at any time of year with proper care.
Yes. Summer planting is common in New Zealand. Ensure regular watering, mulching, and protection from extreme heat.
Yes, especially in frost-free or mild areas. Winter planting allows roots to establish before spring growth.
Most NZ natives tolerate light frosts. Young plants may need protection in colder regions during their first winter.
Generally no. Native plants prefer low-nutrient soils. If needed, use a fertiliser specifically formulated for NZ natives.
Spring & Summer: 2–3 times per week initially
Autumn: Weekly, depending on rainfall
Winter: Only if soil dries out
Once established, most native plants require minimal watering.
Yes. Mulching helps retain moisture, suppress weeds, and regulate soil temperature. Keep mulch clear of the stem.
There’s no need to wait for the “perfect” season.
NZ native plants are tough, adaptable, and well suited to year-round planting.
With the right care and guidance, every season offers an opportunity to grow a thriving native garden.
