- Summer (December – February) is milder than in much of mainland Australia, allowing for a longer growing season for various crops. Gardeners should be careful of heat waves, which may necessitate extra watering and plant care.
- Autumn (March-May) provides cooler weather and more rain. This season is ideal for establishing winter crops and harvesting numerous summer-planted crops.
- Winter (June – August) is relatively cold and rainy. While low temperatures limit the growth of many plants, some winter crops flourish in these conditions.
It is crucial to note that the climate of Tasmania differs around the state. The west is wetter and cooler than the East, affecting what and when you can plant.
When designing your garden, keep your geographical conditions in mind. The distinctive Tasmanian climate presents both obstacles and opportunities. With the proper knowledge and preparation, you may have a productive garden all year.
What veggies to plant now in Tasmania
What to plant in Spring (September – November)
Spring is a time of regeneration and growth in Tasmania. Temperatures are rising, days are getting longer, and the soil is warming up, creating ideal circumstances for many plants to thrive.
Some of our favourite things to plant in Tasmania for Spring include:
Celery is an excellent spring vegetable in Tasmania since it thrives in lower temperatures and matures for a long time.
September is an excellent month to begin planting, allowing your celery to get a jump start on the growing season. Because this plant adores sunbathing, choose a sunny spot with well-drained, pH-neutral soil rich in organic matter.
Watering regularly is necessary to avoid bitter-tasting stalks, and a layer of mulch around the plants helps keep soil moisture. With appropriate care, you should be able to harvest your celery by February.
Celeriac, like celery and mild spring weather, makes September an ideal time to plant. This vegetable prefers full, light and well-drained, organic-rich soil.
Regularly water and support growth with compost or a balanced organic fertiliser. Keep an eye on your celeriac; harvest when the root bulbs reach around 10 cm in diameter, usually around February.
Corn grows best in warmer weather, so planting in Tasmanian spring, particularly in November, provides the optimum conditions.
Make sure you plant your corn in a sunny spot with well-drained soil. Work in old manure or compost before planting to assist its high nitrogen needs. By February, your corn should be ready for harvest.
Eggplant loves heat; therefore, planting in the spring is vital for a great yield. We recommend planting undercover in November to give this veggie enough time to mature over the Summer.
Ensure your eggplant gets enough sunlight and grows in healthy, well-drained soil with a pH of around 6.5.
Consistent watering is essential, especially during fruit growth. If all goes well, you can harvest your eggplant around February or March.
Because peas prefer milder weather, planting in the spring, especially in September, assures a decent crop before the summer heat. Choose a place with full sun to partial shade and well-drained, nutrient-rich soil.
Peas dislike too wet circumstances, so keep the soil moist but not waterlogged. You should be able to enjoy your pea harvest around December or January if you take care of it.

What to plant in Summer (December – February)
Summer in Tasmania, which lasts from December to February, is distinguished by mild temperatures, long sunny days, and lower rainfall than other seasons.
With average temperatures ranging from 12 to 21°C, it’s a good season to cultivate a range of vegetables, using the abundant sunshine and the natural fertility of Tasmanian soil.
Some plants to consider planting during the Tasmanian Summertime include:
Due to their fast maturation rate and resilience to a wide range of temperatures, Asian greens such as bok choy or pak choi are perfect for summer planting, particularly in December.
They grow best in full sun or partial shade on well-drained soil treated with organic compost. Watering regularly and weekly dosing with liquid fertiliser will promote foliage development. Harvesting may usually begin 4-6 weeks after planting, so you can expect a healthy crop in January or February.
Although broccoli is generally a cool-season crop, it can be planted in the Summer, particularly in February, for an autumn harvest in Tasmania’s temperate environment. Broccoli requires full sun and healthy, well-drained soil that is somewhat acidic.
Watering regularly and feeding with high-nitrogen fertiliser are essential. Broccoli heads should be ready for harvest by late April or early May.
Cauliflowers, like broccoli, can be planted in February for an autumn crop. A site with full sun and organic matter-rich soil is best for their growth. Watering constantly is another essential factor for the development of the cauliflower head. Providing balanced nourishment to the cauliflower plant will ensure a strong crop suitable for harvest in May or June.
Cucumbers thrive in the summer heat and should be planted in a sunny, well-drained site in December. They are heavy feeders, so amend the soil with compost or well-rotted manure before planting.
We also recommend regular watering to avoid bitter-tasting fruit. Cucumbers should be ready to pick in February or March if properly cared for.
Tomatoes are a popular summer produce that should be planted in December for a bumper crop. They demand a sunny location with well-drained, nutritious soil and regular irrigation.
Lower leaf pruning and tomato cages or poles can assist in promoting ventilation and reducing disease risk. If everything goes as planned, you can enjoy ripe, luscious tomatoes from February to April.
