Real Stories, Real Success with WormGro

“I’ve been wanting to avoid synthetics and stay as natural as possible, but our soil tests showed we were low in N,P,K & S and Zinc. WormGro Balance was tailored to what the soil actually needed, and I can honestly say the results blew me away. The oat hay came up so healthy — we’re on track for about 250 bales an acre (625 bales/ha). Even other local farmers have been stopping to ask what I put on it, assuming I’d used heaps of urea. When I tell them it was only WormGro, they can hardly believe it. I’d recommend it to anyone who wants healthier soil and a strong crop without relying on synthetics. The results have been amazing, and I plan to buy more WormGro soon.”

262 Bales Per Acre Without Synthetics – Oats for Hay Success

“I used WormGro Plus on a pretty run-down ryegrass paddock here in Wodonga. I put MAP and Calciprill on both plots — one got 100 kg of Urea per Ha and the other WormGro Plus 10L per Ha. The results were just as good with WormGro, but it worked out a lot cheaper. I’m exploring trying it on a bigger scale.”
— James Wallace, Wodonga, Victoria

WormGro Plus Matches Urea Performance at Lower Cost – Pasture Trial

We came across Kookaburra Worms entirely by chance – how grateful we are. We used the WormGro product on some of our commercial lucerne hay crops on a 16 acre black clay soil plot. The outcome of that was that prior to application it needed 4 waters and produced an average of 25 bales/acre with nil synthetic fertilisers. After application of 20L/ha WormGro, we needed only 2 waters and got an increase in yield up to 30 bales/acre.

Vermijuice is not easy to find. I searched far and wide. Then I remembered Kookaburra Worm Farm. A local, and well known for his fishing worms. I rang and asked about the worm pee, or vermi juice. George was happy to sell me a few litres. I wanted to move away from the chemical fertilisers. After all, you are what you eat, and worms are all natural, as is the stuff they eat. The first lot I tried on my Black Russian Tomatoes. I had tried to grow them the previous year, but they didn’t do well, and weren’t exactly fruitful.
So, I tried again, this time with Kookaburra Farms Worm Gro. Wow, what a difference. Using the Worm Gro as a fertigation method, with only water, no other additives, the Tomato plants fairly jumped out from the ground. Excellent flowering, and some of the biggest Tomatoes I had ever grown. Next I tried it on some of my ornamental plants. Green shoots all round, healthy root systems, and great flowers.
I didn’t need to use a lot. Just a splash in the watering can. Probably 30-50ml per can. I love my natural plant tonic from Kookaburra Worm Farm, and I’m so glad it will be on sale to everyone. Just a little goes a long way.

Your Questions, Answered
Think of WormGro PLUS as your regular WormGro that went off to agricultural college and came back with a degree in plant nutrition. The headline difference is the balanced 10:10:10 NPK formulation that gives your crops immediate access to the major nutrients they crave.
But here’s where it gets interesting for your bottom line: Unlike traditional NPK fertilizers where you’re essentially feeding the neighborhood waterways and atmosphere as much as your crops, the microbes in WormGro PLUS fully chelate these nutrients. This means nearly 100% plant availability without the usual leaching and volatilization that has you applying more product than your crops actually use.
The result? You’re applying significantly less product for the same or better results. Your plants get the immediate productivity boost they need, while the million-plus microbial species (yes, that’s not a typo—million-plus species) continue working behind the scenes rebuilding your soil structure and health.
This isn’t just another input—it’s George’s answer to the question farmers have been asking for years: “How do I transition away from high chemical inputs without sacrificing yield?” After decades of research, WormGro PLUS delivers that rare agricultural unicorn: better yields, healthier crops, enhanced water storage, reduced disease and pest pressure, AND improved profitability. It’s the transition technology that lets you have your cake and eat it too…or perhaps more appropriately, grow your cake and sell it too.
WormGro stands apart as a natural bio-fertiliser, rich in beneficial microorganisms and essential nutrients. WormGro does not always replace chemical fertilisers but significantly enhances their effectiveness, thereby reducing the amount needed.
Absolutely! WormGro is versatile and suitable for a wide range of crops, including vegetables, fruits, grains and ornamentals. Its balanced nutrient profile and microbial content make it adaptable across various soil types and climatic conditions, ensuring optimal growth and health for virtually any plant species.
WormGro is an eco-friendly choice, contributing to regenerative agriculture by reducing reliance on chemical inputs, enhancing soil biodiversity, and improving water retention. Its production process is low-impact, and its use promotes a healthier, more resilient environment by fostering natural soil regeneration and reducing carbon footprint.
The application frequency of WormGro depends on the type of plants and their growth stage. Generally, it can be applied every 2-4 weeks in a domestic garden situation. For commercial farming guidance it can be tailored to your crop needs and we can even brew bespoke batches following soil samples being shared.
Yes, WormGro plays a significant role in enhancing plants’ natural defence mechanisms. The diverse microbial life within WormGro helps build biological resistance, making plants less susceptible to pests and diseases. This reduces the need for chemical pesticides, leading to healthier, more resilient plant growth.
On average you can supplement at least 50% of your chemical fertiliser use with WormGro. Contact us for specific, tailored advice for your unique farming situation.
That’s the signature of our nitrogen-fixing powerhouses at work. These carefully selected microbes aren’t just hanging around looking pretty—they’re your soil’s new fertility engine. The stronger the smell, the harder they’re working to boost your next yield.
Dilute to apply 10-20L/ha depending on your soil conditions and crop demands. Unlike that expensive chemical fertilizer collecting dust in your shed, a little WormGro goes a long way. Your wallet and your soil microbiome will both thank you.
Those million-plus microbes prefer the VIP treatment: low-pressure, high-flow nozzles. High pressure turns your biological investment into microbial confetti. These aren’t your standard inputs—they’re living organisms that deserve some respect!
Apply when UV radiation is lowest—late afternoon or evening is ideal. And if your irrigation is scheduled or rain’s on the radar, even better. Think of it as giving your microbial workforce the perfect conditions for their night shift.
You know the drill—it’s for your soil, not your stomach. Don’t drink it, don’t inhale it, wash up after application. You’ve handled enough farm inputs to know the basics. It’s natural, but nature isn’t always meant to be consumed directly!
Test before you invest! Always run a compatibility jar test before combining WormGro with other liquid inputs. We’ve got over a million microbial species in there working their magic, and some of them don’t play nicely with certain chemistry. That precipitation you might see isn’t just inconvenient—it’s a warning sign that could lead to blocked nozzles, filters, and an afternoon spent disassembling your sprayer when you should be in the cab getting work done.
WormGro has a shelf life of 12-24 months, with longevity depending on your storage conditions. Think of it like your seed inventory—keep it cool and it’ll maintain viability longer. The cooler your storage area, the longer your microbes will remain active and ready to perform in the field. Just avoid freezing temperatures that could damage those hard-working microbial populations.
