A splash in the can.A garden that jumps.
The same worm cast biology Queensland farms put on by the hectare, in a 1L twin-chamber bottle with the measure built in. Certified organic. Safe on natives, edibles and indoor plants. 20ml in a 10 litre can covers 10 square metres.

What changes in the bed
It is not a tonic. It is the biology your soil lost.
Bagged potting mix and tired garden beds are close to sterile. WormGro puts over one million microbial species back, and they do the work a bag of fertiliser only pretends to.
Soil that holds water
Microbes bind particles into crumbs that soak up a watering instead of shedding it. Pots dry out slower, beds stay moist deeper.
Greener leaves, bigger blooms
Freed phosphorus grows larger root systems, and larger roots grow everything above them. Flowering comes on stronger and lasts longer.
Fewer pests and diseases
A plant with high Brix and a busy root zone is a harder target. Many gardeners drop the sprays once the biology is back.
Nothing synthetic
Certified organic, so herbs, vegetables and fruit grow in a clean bed. You are what you eat, and so is the tomato.
How to use it
Dip, water, stand back.
There is no technique to learn. The twin-chamber bottle measures the dose for you; the watering can does the rest.
Dip the roots at planting
Mix 1 part WormGro with 10 parts water in a bucket and dip the root ball or bare roots for a few seconds. Seedlings, repots and bare-rooted trees all get the same start.
Add it to the can
20ml in a 10 litre can does 10 square metres. Every 2 to 4 weeks through the growing season, on the soil or over the leaves as a foliar.
Watch it jump
Expect more flowers, bigger fruit and roots you can see the difference in at the next repot, with up to half the fertiliser you used before.

How much for your patch?
Slide to your garden's size and read off the dose. A little goes a long way: most backyards get a season from one bottle.

Rule of thumb: 20ml in a 10 litre can does 10 square metres, every 2 to 4 weeks through the growing season. One 1L bottle covers about 500 square metres per application.

From a watering can
Black Russian tomatoes, second attempt.
“The tomato plants fairly jumped out of the ground. Excellent flowering, and some of the biggest tomatoes I had ever grown. Just a splash in the watering can. A little goes a long way.”

Gardeners ask
Natives, pots, pH and how often.
Yes. WormGro is low in phosphorus, which is the thing natives object to in most fertilisers. Grevilleas, banksias and the rest of the phosphorus-sensitive crowd take it at the same dilution as everything else.
Yes, and it is one of the best uses. A few drops in the watering can, or a quick root dip when you repot, gives potting mix the biology it never had. Dilute it as you would outdoors, a minimum of 1:10.
Every 2 to 4 weeks is the label rate for a domestic garden through the growing season; the farm's general guidance for established gardens is every 4 to 6 weeks, adjusted to the plant and the weather. It does most for plants in their early growth stages and at planting, with spring and autumn applications carrying established plants.
No. WormGro is pH balanced and has a neutral effect on soil, so it will not push acid-lovers or alkaline-lovers either way. Just never pour the concentrate on neat; always dilute it in water first.
Apply it to the roots instead. The microbes need to be where the roots are, so a root dip at planting and WormGro in the can afterwards puts them exactly there. Mixing it dry through a bag of potting mix wastes most of it.
It can replace sea mineral and microbial products outright, and most gardeners cut their synthetic fertiliser by about half in the first year and more after that. It is a worm cast extract fortified with minerals, so you get the biology and the nutrition from one bottle.
