Australia’s vast landscape offers various climates and growing zones, making October an ideal time to start planting a variety of fruits and vegetables for a family of four. This blog post will guide you through what to grow in October, how much space is required, how to prepare the soil, what to plant, and how long it will take to harvest—tailored for each major growing zone in Australia: Tropical, Subtropical, Temperate, and Arid.
Tropical Zone (e.g., Northern Queensland, Darwin)
What to Grow:
In October, tropical regions are warm and wet, creating perfect conditions for heat-loving crops.
- Vegetables: Sweet corn, beans, capsicum, cucumbers, zucchini, eggplant, pumpkin.
- Herbs: Basil, lemongrass, coriander.
Space Requirements:
For a family of four, you’ll need about 10-15 square meters of garden space. This area allows for a mix of climbing and ground-sprawling vegetables.
Soil Preparation:
- Clear the Area: Remove any weeds and grass from the plot.
- Loosen the Soil: Dig down about 30 cm to aerate the soil.
- Add Organic Matter: Incorporate compost and well-rotted manure to improve soil fertility.
- Mulching: Add organic mulch like sugarcane or straw to retain moisture and suppress weeds.
Planting Tips:
- Spacing: Plant pumpkins and zucchini in mounds at least 1 meter apart. Corn can be planted in blocks for better pollination, with seeds 20 cm apart.
- Watering: Regular watering is essential in the tropical heat, especially early morning or late afternoon.
- Fertilizing: Apply a balanced organic fertilizer every 3-4 weeks.
Time to Harvest:
- Sweet Corn: Ready in 12-14 weeks.
- Zucchini: 6-8 weeks.
- Capsicum: 10-12 weeks.
Subtropical Zone (e.g., Brisbane, Coastal New South Wales)
What to Grow:
Subtropical areas have mild spring conditions in October, perfect for planting a wide range of vegetables.
- Vegetables: Tomatoes, cucumbers, sweet potatoes, beans, chilies, lettuce, rocket.
- Fruits: Watermelon, rockmelon.
Space Requirements:
You’ll need about 10-12 square meters for a family of four, focusing on space-efficient crops like cucumbers and beans which can grow vertically.
Soil Preparation:
- Test the Soil pH: Aim for a pH of 6.0 to 7.0.
- Compost Addition: Incorporate compost and well-rotted manure.
- Raised Beds: If soil drainage is poor, build raised beds about 30 cm high.
Planting Tips:
- Trellising: Use trellises for climbing plants like cucumbers and beans.
- Companion Planting: Plant basil near tomatoes to deter pests.
- Watering: Water deeply twice a week, especially as the temperature rises.
Time to Harvest:
- Tomatoes: Ready in 10-12 weeks.
- Beans: 8-10 weeks.
- Lettuce: 4-6 weeks.
.
Temperate Zone (e.g., Melbourne, Adelaide, Perth)
What to Grow:
In temperate regions, spring is in full swing in October, offering excellent conditions for a variety of cool-season and summer crops.
- Vegetables: Broccoli, carrots, spinach, potatoes, onions, peas.
- Herbs: Parsley, thyme, oregano.
Space Requirements:
A family of four will need about 12-15 square meters of growing space to sustain themselves.
Soil Preparation:
- Enrich with Compost: Add a mix of organic compost and aged manure.
- Soil Testing: Ensure a neutral pH (around 6.5-7.0) for optimal plant growth.
- Mulching: Apply mulch to retain moisture and regulate soil temperature.
Planting Tips:
- Spacing: Plant broccoli and cabbage about 50 cm apart. Carrots and onions can be grown in rows, about 10 cm apart.
- Succession Planting: Plant lettuce or spinach every 2-3 weeks for continuous harvest.
- Fertilizing: Use an organic liquid fertilizer every 2-3 weeks for leafy greens.
Time to Harvest:
- Broccoli: 10-12 weeks.
- Carrots: 12-14 weeks.
- Spinach: 6-8 weeks.
Arid Zone (e.g., Central Australia, Alice Springs)
What to Grow:
Arid regions require hardy, drought-tolerant plants that can thrive in hot, dry conditions.
- Vegetables: Okra, eggplant, capsicum, radishes, melons.
- Herbs: Rosemary, sage, thyme (all drought-tolerant).
Space Requirements:
A family of four will need about 8-10 square meters for a productive garden, focusing on plants that maximize water use.
Soil Preparation:
- Irrigation Setup: Install drip irrigation to conserve water and provide consistent moisture.
- Add Organic Matter: Use plenty of compost to improve moisture retention in sandy soils.
- Mulch: Use a thick layer of organic mulch to reduce evaporation.
Planting Tips:
- Deep Rooting Crops: Plant deep-rooted vegetables like melons and eggplants to tap into moisture further down.
- Watering: Water deeply but less frequently, ensuring the soil is saturated at the root level.
- Shade: Provide temporary shade cloth for young seedlings during hot days.
Time to Harvest:
- Eggplant: 12-14 weeks.
- Okra: 8-10 weeks.
- Melons: 12-16 weeks.
General Care Tips for October Planting
- Pest Control: Keep an eye out for common spring pests like aphids, caterpillars, and slugs. Use organic pest control methods like neem oil or companion planting.
- Weeding: Regularly remove weeds to reduce competition for nutrients.
- Compost and Fertilizer: Top up compost every few weeks and use a balanced organic fertilizer.
- Crop Rotation: Avoid planting the same crops in the same place year after year to prevent soil depletion and reduce the risk of diseases.
Cost Savings of Growing Your Own Food
By growing a backyard garden, a family of four can save anywhere from $500 to $1,500 per year on groceries, depending on the crops planted. For example:
- Tomatoes: Growing 12 plants (costing $10 in seeds and compost) can yield over 30 kg, saving you approximately $200.
- Lettuce: Instead of buying, growing your own can save up to $100 per year.
- Zucchini and Pumpkins: Easy to grow and prolific, these can easily cover months of meals, saving another $200-$300.
