October Planting Guide: Spring into Abundance with Earthfood

Spring in Australia is a season of renewal and abundance. 
The soil warms, daylight stretches longer, and gardens wake up with energy and promise. Blossoms appear, bees return, and the urge to plant is irresistible. October is when we set the stage for a thriving summer harvest.

But spring also brings its challenges 
Frosts in the south, monsoon humidity in the north, sandy soils that dry too fast in the west, and fruit flies just waiting to pounce in the east. Getting it right means planting the right crops at the right time, and giving your soil the living biology it needs to support plants naturally.

With Earthfood’s nitrifying living microbes, you become what I like to call the world’s laziest gardener - microbes do the work, you get the results.
Here’s what to plant across the states this October, plus a few seasonal warnings.
New South Wales & ACT
What to sow: Beans, beetroot, capsicum, carrots, cucumber, lettuce, pumpkin, radish, spinach, silverbeet, sweetcorn, tomatoes, zucchini, watermelon, basil.
What to plant as seedlings: Cabbage, kale, eggplant, chilli, celery, spring onions, strawberries, tomatoes.
Seasonal cautions: Late frosts still bite in Canberra and the Southern Highlands. Tomatoes and zucchini need protection with cloches or frost fleece if planted early.
Earthfood advantage: Microbes improve calcium mobility, preventing blossom end rot in tomatoes. They also buffer soils stressed by frosts, helping seedlings bounce back faster.


Victoria
What to sow: Beetroot, broccoli, cabbage, carrots, kale, lettuce, peas, radish, silverbeet, spinach, spring onions, sweetcorn, tomato, zucchini, pumpkin, watermelon, basil.
What to plant as seedlings: Broccoli, cabbage, cauliflower, kale, leek, lettuce, onion, silverbeet, strawberry, tomato.
Seasonal cautions: Cold snaps and soggy soils still hit southern Victoria. Slugs and snails surge in wet weather, chewing tender seedlings.
Earthfood advantage: Living microbes create a biofilm on roots, increasing resilience to both cold and waterlogging. Healthier seedlings mean fewer losses to slug pressure.


Queensland – South-East & Coastal
What to sow: Beans, beetroot, capsicum, carrots, cucumber, lettuce, pumpkin, radish, spinach, silverbeet, sweetcorn, tomatoes, zucchini, watermelon, basil, coriander.
What to plant as seedlings: Eggplant, capsicum, chilli, sweet potato slips, tomato, passionfruit vines, cucumber, zucchini.
Seasonal cautions: Fruit fly season begins now. Without protection, they’ll ruin your hard work on tomatoes, capsicum, and stone fruit.
Earthfood advantage: Higher Brix (sugar + nutrient density) in plants makes them less attractive to pests. Healthier cell walls = less insect attack.


Queensland – Far North / Tropics
What to sow: Sweetcorn, beans, cucumber, pumpkin, watermelon, okra, snake beans, chilli, capsicum, eggplant, basil.
What to plant as seedlings: Cassava, taro, yams, sweet potato, tropical fruit trees.
Seasonal cautions: The build-up to the monsoon means high humidity, fungal outbreaks, and sudden downpours. Drainage is critical.
Earthfood advantage: Microbes reduce fungal stress by outcompeting pathogens and protecting roots from drowning in saturated soils. Raised beds plus Earthfood = resilience in the wet.


South Australia
What to sow: Beetroot, broccoli, cabbage, carrot, lettuce, peas, pumpkin, radish, rocket, silverbeet, spinach, tomato, zucchini, watermelon, basil.
What to plant as seedlings: Broccoli, cauliflower, kale, leek, lettuce, onion, strawberry, tomato.
Seasonal cautions: October in SA brings dry winds and heat spikes, especially inland. Seedlings can wilt fast.
Earthfood advantage: Earthfood microbes improve water retention, holding condensation at the root zone. SA growers see up to 70% water savings, making seedlings more resilient in dry winds.


Western Australia – South & Perth
What to sow: Beetroot, broccoli, cabbage, carrot, kale, lettuce, peas, pumpkin, radish, rocket, silverbeet, spinach, tomato, zucchini, watermelon, basil.
What to plant as seedlings: Broccoli, cauliflower, kale, leek, lettuce, onion, strawberry, tomato.
Seasonal cautions: WA’s sandy soils lose moisture fast and struggle to hold nutrients. Aphids and whitefly also arrive early with warmer weather.
Earthfood advantage: Microbes create soil structure, improving both water-holding and nutrient retention. They also build plant immunity, reducing aphid attack.


Northern Territory – Top End / Tropical
What to sow: Beans, capsicum, chilli, cucumber, eggplant, pumpkin, radish, snake beans, tomato, watermelon, basil, okra.
What to plant as seedlings: Sweet potato, taro, cassava, pawpaw, tropical fruit trees.
Seasonal cautions: Heat spikes and sudden tropical storms can shock seedlings. Termites are also active now, often targeting stressed plants.
Earthfood advantage: Earthfood microbes strengthen root systems and cell walls, meaning plants survive shocks and resist termite attack.


Tasmania
What to sow: Beetroot, broccoli, cabbage, carrot, kale, lettuce, peas, radish, rocket, silverbeet, spinach, spring onions.
What to plant as seedlings: Broccoli, cabbage, cauliflower, kale, leek, lettuce, onion, strawberry.
Seasonal cautions: Frosts can still hit well into October in the Derwent Valley and Huon. Delay tomatoes, zucchini, and basil until after the frost window closes.
Earthfood advantage: Microbes improve nutrient cycling in cold soils, giving early crops like peas and brassicas a strong start while others wait for warmth.

 A note on Tonification

Spring is the season of abundance 
But only if the soil is alive. Across every climate in Australia, the difference between struggle and success comes down to biology. Water-borne microbes like compost tea and worm juice and “tonics” like Seasol which was 97% water and a 3% salty seaweed tea that dries soils and stresses plants, now it is a Hazardous material called Potassium Hydroxide - since 2024 and changed ownership from Yates to DuluxGroup.

Earthfood is the opposite - a rainforest of living microbes in a bottle.

From backyard gardeners to broadacre farmers, the secret to being “the world’s laziest gardener” is simple: let the microbes do the work. They’ll feed your plants, hold your water, protect your roots, and make you the envy of neighbours and fellow growers.

Gardening SHORT CUT NOTES:

Veggies 
Tomatoes, cucumbers, zucchini, capsicum, beans, lettuce, rocket, and corn.
Tip: Give climbing plants like beans and cucumbers trellises to save space and boost yields.

Herbs 
Basil, coriander, parsley, chives, and mint.
Tip: Plant basil alongside tomatoes — they’re perfect companions that help each other thrive.

Fruits 
Strawberries, passionfruit, and melons.
Tip: Strawberries thrive in well-drained soil and a partly shaded spot. Mulching not only keeps them sweet and pest-free, but also helps retain soil moisture, protects the roots, and reduces weeds.

Flowers (for pollinators) 
Sunflowers, marigolds, and nasturtiums.
Tip: These flowers not only add colour but attract bees, beneficial insects to keep your plants healthy – and edible well. Great to have them in salads.
