What to Grow in Autumn

The arrival of autumn signals the perfect time for rejuvenating your garden. In most of Australia, this season offers optimal conditions for planting a variety of crops. As the temperatures cool and the days shorten, gardeners have the opportunity to establish strong, healthy plants that will thrive throughout winter and into spring. This guide will help you discover the best varieties to plant, region-specific tips, and how to care for and harvest your autumn bounty.

Introduction

Autumn is often considered the best planting season across much of Australia. The cooler temperatures and increased rainfall create ideal conditions for plants to establish strong root systems. Whether you're a seasoned gardener or a beginner, autumn provides a diverse array of planting options. From leafy greens to root vegetables and even some fruits, the season is ripe with possibilities. This guide will navigate you through what to plant, how to care for your crops, and when to harvest them for the best yields.

Best Varieties

Southern Regions (Victoria, Tasmania, South Australia)

• Leafy Greens: Spinach, kale, and lettuce thrive in the cooler weather.
• Root Vegetables: Carrots, beetroot, and radishes can be sown directly into the soil.
• Brassicas: Broccoli, cauliflower, and Brussels sprouts are ideal for autumn planting.

Northern Regions (Queensland, Northern Territory)

• Tropical Staples: Plant sweet corn and capsicum while the soil remains warm.
• Herbs: Basil, coriander, and parsley grow well during the milder autumn days.
• Legumes: Peas and beans can be sown for a winter harvest.

Eastern and Western Regions (New South Wales, Western Australia)

• Alliums: Onions and garlic are best planted now for a summer harvest.
• Tubers: Potatoes and Jerusalem artichokes can be started in early autumn.
• Perennials: Strawberries and rhubarb can be planted for a robust spring yield.

Planting Steps

1. Prepare the Soil: Start by clearing your garden beds of summer crops and weeds. Dig in well-rotted compost or manure to enrich the soil.
2. Plan Your Layout: Consider companion planting to maximise space and deter pests. For instance, plant carrots and onions together.
3. Sow Seeds or Transplants: Follow seed packet instructions for sowing depth and spacing. For transplants, water them well after planting.
4. Mulch: Apply a layer of organic mulch to conserve moisture and regulate soil temperature.

Care & Feeding

• Watering: Although autumn is cooler, regular watering is still essential, especially for seedlings. Water in the morning to prevent fungal diseases.
• Feeding: Use a balanced organic fertiliser to provide nutrients throughout the growing season. Avoid high-nitrogen fertilisers for root crops.
• Pest Control: Be vigilant for slugs and snails, which are common in damp conditions. Use natural deterrents or barriers to protect young plants.

Harvesting

• Greens and Herbs: Harvest leafy greens and herbs regularly to encourage new growth. Pick outer leaves first.
• Root Vegetables: Test carrots and beets for readiness by gently pulling one from the soil. They should be firm and brightly coloured.
• Brassicas: Harvest broccoli and cauliflower heads when they are compact and before the flowers open.

By following these guidelines, you can enjoy a productive and rewarding autumn garden. Remember to monitor local weather conditions and adjust your gardening practices accordingly. Happy planting!
