Our Customer Stories
Real gardeners, real gardens, real growth. Our testimonials are a mosaic of WormGro successes, from beginners to seasoned green thumbs, all witnessing the transformative power of WormGro in their gardens.
“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.

our quick guide ensures that your garden will be the envy of the neighbourhood.

Step 01:
Plant Your Seeds or Root Dip
Directly plant your seeds into the prepared soil, or opt for root inoculation of established plants. Never dipped your roots before? Check out how to incorporate this simple step to transform your garden:
Prepare the Solution: Mix 1 part WormGro with 10 parts water in a bucket to create a solution for your plants’ roots.
Dip Before You Plant: Briefly dip the root ball of your seedling or the bare roots of your older plant into the WormGro solution. This crucial step inoculates your plant with beneficial biology, setting the stage for robust growth and health.
Plant with Confidence: After the dip, plant your seedlings or repotted plants in their designated spots. WormGro’s root dip method supports stronger root development, enhanced nutrient uptake, and overall plant resilience.

Step 02:
Water as Needed
To maximise the results of WormGro, add to your watering can! By adding WormGro when you water your plants after dipping the roots, you are giving your plants the best dose of nutrition all while acting as a natural pesticide and building plant resilience!
A Gentle, Effective Replacement: Regularly watering with diluted WormGro not only supplements but can also eventually replace traditional NPK (Nitrogen, Phosphorus, Potassium) fertilisers in your gardening routine. Its rich composition provides a more natural, sustainable source of nourishment for your plants.
Broad-Spectrum Benefits: Beyond replacing up to 50% of synthetic fertilisers, WormGro can replace sea mineral products and other microbial, bacteria, or mycorrhizal fungi enhancements. It is a versatile, all-encompassing solution that enriches your garden with everything it needs to thrive.

Your Questions, Answered
It will depend on your soil type and plant type, however generally you can expect to reduce your fertiliser input by up to 50% in the first year and more in subsequent years.
When converting from traditional fertiliser to WormGro, a gentle transition over 1-2 growing seasons is recommended. This will deliver better results than a sudden change.
In most cases yes, however it is best to use as a foliar spray. Depending on the pest or disease, it may be necessary to use WormGro more frequently than recommended on the label.
Yes, as it is low in phosphorus.
WormGro can be used throughout the year, but it’s most effective when applied during the early growth stages of plants and before planting. For established plants, spring and autumn applications can support robust growth and health.
We recommend applying WormGro every 4-6 weeks during the growing season to maintain optimal soil health and plant vitality. Adjust frequency based on plant needs and local weather conditions.

WormGro is pH-balanced and generally has a neutral effect on soil pH. It helps maintain a stable environment that is conducive to plant growth and soil microbial activity. Make sure that you never apply WormGro directly to the soil or plant, always dilute it with water (minimum 1:10 ratio).
While mixing WormGro into your potting mix might seem like a good idea, it’s more beneficial to apply it directly to the plant’s roots.
This method ensures that WormGro’s microbes are exactly where they’re needed most, working in tandem with the root system to promote healthy growth. By concentrating WormGro around the roots, you ensure the plant benefits directly from its nourishing properties.
A quick dip is all it takes! Just immerse the roots in the WormGro solution for a few seconds to ensure they’re sufficiently wet. This brief contact is enough to coat the roots with beneficial microbes, setting the stage for a healthy and vibrant plant.
Absolutely! While it’s true that WormGro originates from worm castings, offering a rich diversity of beneficial microbes, it’s also fortified with essential minerals vital for plant growth.
These minerals are present at concentrations comparable to those found in sea mineral formulations, making WormGro a versatile, all-in-one solution for your gardening needs. It’s like having the best of both worlds – microbial richness and mineral nourishment, all from a single, earth-friendly product.
