Why Autumn & Winter Are Key Planting Seasons
Autumn and winter may seem like quieter times in the garden, but they are actually some of the best seasons for planting in Australia and other regions with mild winters, such as New Zealand, parts of the southern USA (California, Texas, Florida), Mediterranean regions (Spain, Italy, Greece) and parts of South Africa.
For many gardeners, cooler months allow plants to establish strong root systems before the heat of summer. Whether you’re growing vegetables, flowers, or fruit trees, this time of year allows plants to establish strong roots before the heat of summer.
✔️ Stronger Root Development – Cool-season planting helps plants develop robust root systems before rapid growth in spring.
✔️ Better Water Management – Cooler weather and increased rainfall reduce water stress that plants experience during the hotter months. However, this can also lead to flooding and waterlogging in some areas. With good drainage, better soil and raised beds you can help prevent root rot.
✔️ Pest & Disease Management – Fewer pests compared to spring and summer, reducing the need for intervention.
✔️ Year-Round Growing Potential – In warmer coastal areas and regions with mild winters, many vegetables and flowers can be grown almost year-round.
👉 In colder climates, winter is the time to plant bare-root fruit trees, prepare soil for spring, or use cold frames/greenhouses for growing leafy greens.
The Most Important Step: Preparing Your Soil for Autumn & Winter Planting
No matter what you’re planting, healthy soil is the foundation of success. Before sowing seeds or planting seedlings, take these steps:
- Improve Soil Structure – Add compost and products like Humus Powder or ViAGrow to boost water retention and microbial life.
- Replenish Nutrients – Use an organic fertiliser like UGF6in1 to provide essential nutrients. Organic fertilisers like UGF6in1 are more bio-available and therefor your plants can utilise more of these essential nutrients and trace elements.
- Mulch for Moisture & Protection – Applying mulch helps regulate soil temperature and prevent weeds.
- pH Testing – Certain plants, like brassicas, thrive in slightly alkaline soil, while berries prefer acidic conditions. Adjust pH accordingly.
👉 In colder climates with harsh winters, prepare soil for spring planting by adding organic matter and covering garden beds with mulch or row covers.
Best Herbs & Vegetables to Plant in Autumn & Winter
Autumn and winter are the perfect seasons for growing cool-season crops that thrive in lower temperatures.
Australia (Temperate & Cool Climates)
🌿 Herbs – Hardy varieties like rosemary, thyme, oregano, parsley, coriander & chives (Harvest: from 4–8 weeks, some perennial)
🥦 Brassicas – Broccoli, cauliflower, cabbage, Brussels sprouts (Harvest: 10–16 weeks)
🥕 Root Vegetables – Carrots, beets, radishes, turnips (Harvest: 6–12 weeks, radishes from 4 weeks)
🥬 Leafy Greens – Spinach, kale, silverbeet, rocket, lettuce, watercress, sorrel or chervil (Harvest: 4–8 weeks)
🧄 Alliums – Garlic, onions, leeks, shallots (Harvest: 16–30 weeks depending on type)
🌱 Legumes – Peas, broad beans (Harvest: 10–14 weeks)
👉 In colder climates with harsh winters (Northern USA, Canada, UK), many of these crops can be grown in greenhouses, cold frames, or indoors with proper lighting.
Flowers to Plant in Autumn & Winter
Many flowering plants thrive when planted in autumn and winter, setting the stage for beautiful blooms in spring and summer
Australia (Temperate & Cool Climates)
🌷 Bulbs – Daffodils, tulips, jonquils, crocuses, hyacinths
🌸 Hardy Annuals – Pansies, violas, snapdragons, sweet peas
🌿 Perennials – Delphiniums, foxgloves, aquilegias, hellebores
🌻 Wildflowers & Natives – Kangaroo paw, grevilleas, bottlebrush
👉 In colder climates, plant bulbs before the ground freezes, or start flowers indoors in seed trays to transplant in spring.
Best Shrubs, Fruit & Nut Trees to Plant in Autumn & Winter
Autumn and winter are the best times to plant deciduous fruit trees, as they can establish their roots before spring growth.
🏡 Native shrubs – Banksias, grevilleas, wattles
🌳 Deciduous trees – Maples, oaks,
🍎 Fruit Trees – Apples, pears, peaches, nectarines, plums, cherries
🍋 Citrus Trees – Lemons, oranges, mandarins, limes (ideal for warmer regions)
🌰 Nut Trees – Almonds, walnuts, hazelnuts
🍓 Berries – Raspberries, blueberries, blackberries, strawberries
👉 In colder climates like the UK, USA, and colder European regions, winter is the time for bare-root fruit trees, which should be planted before early spring.
Want Colour Now? Plants That Bloom During Winter
While most flowers planted in autumn or winter bloom in spring or summer, a few hardy varieties bring colour even during the coldest months:
- Pansies & Violas – Reliable performers that flower through winter in mild climates
- Hellebores (Winter Rose) – Blooms from late autumn to early spring
- Calendula – Often flowers right through winter with cheerful orange and yellow tones
- Snowdrops & Eranthis – For cooler climates, bloom in late winter
- Grevillea & Correa (Native Shrubs) – Many varieties flower during winter and attract birds
These flowers can be planted earlier in autumn, or if you’re looking to brighten up your winter garden, many are available as seedlings or potted colour (blooming potted plants)— perfect for adding cheerful blooms even in the cooler months.
How to Protect Your Winter Garden from Frost & Pests
While winter gardening has fewer pest problems, frost and hungry animals can be a challenge.
🔥 Use frost cloths – Protect delicate plants with row covers.
🌱 Mulch heavily – Insulates roots against cold temperatures.
🐛 Monitor for pests – Aphids and caterpillars can still be an issue.
👉 In colder climates when growing in snowy regions, create raised beds or poly tunnels to extend the growing season.
Boost Your Garden with a Natural Fertiliser Like UGF6in1
Giving your autumn and winter plants the right nutrition is just as important as choosing what to grow. While cooler weather reduces water stress and pest pressure, nutrient availability in soil can still be a limiting factor—especially for crops and flowering plants that need a strong start.
A high-quality, natural fertiliser like UGF6in1 helps:
- IMPROVE root establishment for stronger, more resilient plants
- SUPPORT lush, healthy foliage even in cooler weather
- ENHANCE flowering & fruiting for trees, veggies, and ornamentals
📌 Tip: Australian Gardener of the Year Chas Smith swears by foliar feeding with UGF6in1 for his dahlias in Tasmania—proving it works wonders even in cooler seasons! Read more HERE
How to Apply UGF6in1 for Best Results
- As a soil drench before planting to boost microbial activity
- As a foliar spray to strengthen leaves & stems
- As a seasonal booster for flowering plants and fruit trees
