Spring is the busiest planting window in the Australian gardening calendar, but what actually goes in the ground varies a lot depending on where you live. A planting guide written for Melbourne doesn’t translate directly to Cairns, and vice versa. Here’s a practical, climate-aware starting point.
Know your climate zone first
Australia spans several distinct growing climates, and spring means something different in each:
- Temperate south (Melbourne, Adelaide, Hobart, southern NSW): spring is a genuine transition from cold to warm, with frost risk lingering into early spring in some areas.
- Subtropical (Brisbane, the Gold Coast, northern NSW): mild winters mean spring arrives early and warms quickly, with a shorter frost risk window.
- Tropical north (Darwin, Cairns, far north Queensland): spring falls in the build-up to the wet season, hot and increasingly humid rather than cold-to-warm.
- Arid and semi-arid inland: spring brings welcome mild temperatures before summer heat sets in, with water-wise planting a priority.
- Cool and alpine areas (Tasmania, Victorian and NSW highlands): frost risk can extend well into spring, so timing matters more here than almost anywhere else.
If you’re not sure which category best fits your area, a local nursery or your state’s gardening extension service can confirm your average last frost date, which is the single most useful number for timing spring planting.
Vegetables to plant in spring
Once frost risk has genuinely passed in your area, spring is prime time for warm-season vegetables:
- Tomatoes, capsicum and chilli
- Cucumber, zucchini and pumpkin
- Sweet corn
- Beans (both climbing and bush varieties)
- Herbs like basil, coriander and parsley
In warmer subtropical and tropical zones, many of these can go in earlier, while cooler and alpine gardeners are often better off waiting until late spring to avoid a late frost knocking back tender seedlings.
Flowers and ornamentals
Spring is also the standout season for colour. Australian native options like grevillea, bottlebrush and kangaroo paw generally establish well in spring and are more forgiving of dry spells once settled in. For a quicker colour hit, petunias, marigolds and dahlias are reliable spring performers across most of the country.
Fruit and perennials
Spring is a good time to plant citrus, which benefits from establishing before summer heat arrives, along with passionfruit vines and strawberry runners. These are longer-term additions to a garden, so it’s worth giving some thought to their eventual size and sun requirements before choosing a spot.
General spring garden tasks
- Refresh garden beds with compost or well-rotted manure before planting
- Apply a layer of mulch to retain moisture as temperatures climb
- Start checking regularly for early pest activity, aphids and caterpillars tend to appear as the weather warms
- Ease into a regular watering routine rather than waiting until plants are visibly stressed
A few practical planting tips
If you’re planting seedlings raised indoors or bought from a nursery that’s been kept under cover, harden them off gradually over a week by giving them a few hours of outdoor conditions each day before planting out fully. Water new plantings in well at the time of planting, and go easy on fertiliser until they’ve had a chance to settle in, overfeeding new plants can do more harm than good.
Spring planting works best when it’s matched to your local conditions rather than a generic calendar. Checking with a local nursery for exact timing in your area, particularly around frost dates, will save more disappointment than any general guide can prevent.
